Another peculiar (and strictly anecdotal) situation: the Turbine blu-ray files offer superior results on my Android TV. I don't know why this is.

I tried playing the raw Universal DVD files and the raw Turbine blu-ray files of "Luck of the Draw" on my Android TV box (hooked up to my HDTV) with the MX Player app.

My Android TV box did something strange: it oversaturated all the colours, making Quinn and Arturo look weirdly orange. Everything was too rich. There seemed to be some oversharpening as well: the raw DVD file looked blocky, jagged and the amped up colour accentuated the DVD compression and artifacts. It looked hideous.

I tried playing the file in VLC and got the same results. It must be something within the MiBox 3's SoC and decoding settings that's adding increased saturation. I've never noticed oversaturation with my other video files on my MiBox 3. Maybe they benefit from it and Season 1 of SLIDERS doesn't.

I have no idea why it did this; my HDTV has the same colour profile for the blu-ray player. I played the raw file on my blu-ray player and my blu-ray player didn't increase the colour or sharpen the video so unflatteringly.

I played the Turbine version of "Luck of the Draw" on my MiBox 3 -- the blu-ray file as MKV. The colour saturation was increased here as well, but because the raw file was discoloured, the increase made it look normal. In addition, there seemed to be some mild sharpening and the raw blu-ray file looked okay -- certainly not HD or even at the level of the post-Season 1 episodes, but adequate and acceptable as an upscaled image on an HDTV. It looked as good as the upscaled Universal DVD on my blu-ray player.

It's very strange. Speaking only for the equipment I have here: for Android TV playback, the Turbine versions turn out best. For upscaled DVD playback, the Universal versions are best.

Now you know why colorists tear their hair out trying to do film coloring.  So many variables.

Interesting..

Yeah, looking at the Universal DVDs (any episode): there's compression artifacts. Blockiness. Noise that isn't film grain.

Looking at the Turbine blu-ray: the compression artifacts are not there. Any noise on the image is film grain. However, the compressed Universal DVD is artifacted and blurry for post-Pilot Season 1 episodes. The uncompressed Turbine image for Season 1 is not artifacted, but a bit blurrier and missing almost half the colour.

Put the raw video files from the discs side by side and Turbine looks washed out and fuzzy while Universal looks saturated, blocky and also a bit fuzzy if you look past the blocks. Put the discs in an upscaling player and they end up looking about the same.

I'm afraid I made a mistake. You see, when I first got the blu-ray, I was raving about how great the blu-ray SD files looked for Season 1 on my HDTV. But I see now: I was ascribing to the disc all the great work that my disc player was doing. I have a feeling my job application for blu-ray.com will not be going forward.

big_smile

One thing to also remember is how different Goodfellas looked for you vs. me.  I had what seemed to be a lot of pixelation (compression artififacts?).  I know it's S2, and you're talking about S1 above but the image looked terrible.  That said, I mostly found S2 episodes better on turbine than universal.

I've been rewriting the first post of this thread, updating it with a summary of the video quality of each DVD set.

I've come to realize something: the Universal DVDs are not bad. I've said repeatedly that they are, but they aren't. Yes, DVD compression and interlacing can diminish video quality, but upon further review and comparison, the Universal SLIDERS DVDs don't have particularly small file sizes (1.6 - 1.8 GB per episode). The non-Pilot Season 1 episodes look terrible because the video masters are blurry, because they were film transferred to analog low resolution videotape. The DVD compression and interlacing don't do it any favours, but lifting off the compression and decombing have only further revealed the poor quality of the image underneath.

Seasons 2 - 5 on the Universal DVD sets look good. DVD compression and interlacing have marred them, but the underlying video image is sharp, detailed and defined; the film to digital videotape transfer has maintained a scaled down version of the film's crisp detail. An upscaling blu-ray player and/or HDTV upscaling can make them presentable; AI upscaling can make them look like impressive HD approximations.

Mill Creek, however, is bad; Season 1 looks terrible, blurry and artifacted from overcompression, Seasons 2 - 3 are hovering around poor to okay, looking fuzzier than the Universal versions and covered in blockiness and noise. Seasons 4 - 5 look average; the 16mm film image is grainy to begin with and a decent blu-ray player and/or HDTV upscaler can smooth out Mill Creek's damage while AI upscaling can remove it completely.

I think Season 1 looking so bad on Universal just made me feel biased against the rest of the Universal discs, but I've come to realize that SLIDERS' video quality on the Universal DVDs is as good as it can be within the limitations of DVD and the masters.

It's interesting that you mention that. I've always thought seasons 3-5 look good on dvd, 4-5 really respectable for sd.

S1&2 hasn't held up for me but the initial reviews were pretty positive. 

As far as I understand though universal was still doing 500mb per episode, correct?   Outside the pilot.

It would be interesting to see Tracy and Marc's work together since they both have an appreciation for the Twlight Zone angle of sliders.

That said, I honestly wonder if Tracy's black comedy or SNL type humor in general would be a "frequency" Marc would totally also be able to operate on. 

I think Tracy and Larry Wilmore might be an interesting pairing where they could riff of each other tho I am not sure if they'd have some clashing worldviews (not to mention Larry would be like who the heck is this Quinn guy and why are we going back to him.. so there's that oroblem)

With THE DEAD ZONE: Seasons 1 - 3 after Topaz upscaling look absolutely perfect. 10 out of 10. They look like a digital film scan.
It's because Seasons 1 - 3 are grain based images from 16mm film, edited on high definition digital videotape and downscaled for broadcast and DVD and with all the film grain still present and available for an upscale.

However, THE DEAD ZONE's Seasons 4 - 6 after an AI upscale look like an upscaled DVD. It is an amazing upscale and no blu-ray player could do this sort of upscale during playback because all the compression artifacts are gone and the resolution has been increased through smooth pixel blending specific to the image textures to ensure no new artifacts or imperfections. But fine details like pores and grass have a slight blur to them. It's because these seasons are pixel based images from digital cameras, edited digitally, then downscaled for broadcast and DVD.

The DVDs themselves look pretty much the same across all six seasons of this show in terms of video quality and characteristics (grain, sharpness, clarity, detail). There's no weird discrepancy like Season 1 of SLIDERS being denoised and blurry and Season 2 being sharp and grainy. THE DEAD ZONE made some effort to retain its visual identity even though its cameras and filming location changed.

However, THE DEAD ZONE's look certainly shifted with digital cameras, but where SLIDERS benefitted greatly from the digital videotape format, THE DEAD ZONE suffered a little for the transition into a fully digital format. The first three seasons of DEAD ZONE benefitted from film because for film, productions light everything with thought as to how that light will show up through the film chemical process.

In contrast, digital videography captures video 'as-is,' and lighting and colour are often adjusted afterwards. There is less thought put into lighting a scene as it's adjustable in post, there are also artistic limitations. Seasons 1 - 3 were very artful and deliberate in lighting. Johnny Smith's house in THE DEAD ZONE had, in Seasons 1 - 3, a cozy warmth with a sense of amber comfort where every room seemed to be lit like it had a fireplace even if it didn't. From Seasons 4 - 6, Johnny's house just becomes 'dark.' It could be fairly said that THE DEAD ZONE's later seasons' use of digital cameras just make it look cheaper and shabbier much like SLIDERS in Seasons 4 - 5 not really bothering to use colour or its absence for storytelling and just looking beige.

Nothing to do with video quality itself, of course.

Keep in mind, the reason they went to digital video and cut out film in the deadzone may have been a strong need to lower cost, and in that strong need, the desire to light it well or work longer hours to light it well may have diminished.  I guess I am saying, it may not have been 100 percent about the flexibility to adjust in post, it may have also been like, "this show isn't not a big enough of a hit to put as much thought in it, let's just shoot in dv and keep it moving. get to 88 episodes and syndication."

hmm. I am comparing it with Into the Mystic and not noticing a difference?

So does that mean that THE DEAD ZONE content for S1-3 looks better after topaz processing than S4-6?

I assume on the dvds itself, the 1-3 don't look as good at 4-6?  Or maybe that's a draw.

You know, RussianCabbie, I think you're right that the Artemis medium quality preset might be better suited to the Season 1 episodes. Here's "Fever" via Artemis MQ preset. 

I have to say, this is looking better than the HQ result. The wide and medium shots had serious aliasing issues in the original video files. The HQ preset didn't make that worse, left it alone but inflated the issue of edges of people and objects having phantom outlines around them. The MQ preset smooths that out, adding a touch of blur to those outlines, blending these flaws out of the image. There's a bit of blurriness, but it's for a wide shot.

Well you get all the credit here, I was just asking some questions along the way. 

ireactions wrote:

I guess I'm upscaling the other seven post-Pilot episodes of SLIDERS again, this time on the MQ preset. What is this, the seventh time? The eighth? I've had to position some ice packs below the laptop stand for extra cooling.

About 15 years ago, I broke an older laptop whose fan was dead because I kept watching video on it for a sustained period of time and it got to hot..



I don't hear anything in the commentary about the technical means for filming the Pilot scene with Quinn and Smarter Quinn aside from remarks that they found a body double who looked just like Jerry O'Connell once they put a wig on him. Torme says that Jerry had an uncannily close body double in the recent livestream, too.

I'm guessing that this person is James Bamford, a Vancouver stuntman who's career began in 1994 with VIPER (shot in Calgary) and MANTIS (in Vancouver). Bamford performed as Jerry's body double in "The Unstuck Man," and I'm assuming that he was Jerry's double between the Pilot and Season 5 too before going back to Vancouver to serve as stunt coordinator on numerous shows and then moving into superhero TV directing in 2016.

They did merge alternate sides of the film negative over each other. But it's customary to have a body double play the other side of the scene so that the actor has a scene partner for timing. Jerry would have performed in the shot as Quinn alongside a body double playing Quinn-2. Then Jerry would have performed the same shot as Quinn-2 with a body double for Quinn. These shots would then be composited on top of each other; the sides of the shots with Jerry's Quinn would be kept and the sides with the body double would be covered.

I can't recall where I heard the two week thing, but I don't misremember those sorts of things.  Maybe it was in the Sliders EPK, if not the dvd commentary, maybe it was in an article.  I remember being quite surprised.  I think the result turned out amazing though.  Especially the side shot of the vortex.


I would argue that in "Greatfellas," Cleavant plays Rembrandt and Rembrandt-2 and Clinton is used as a body double. Cleavant plays Rembrandt-2.

Yes, in shots where both Rembrandts are in the same frame, Clinton's face is certainly visible and can be distinguished from Cleavant, but Clinton is always slightly angled or moving (but not obscured). Also, the double shots have Cleavant and Clinton switch roles to try to average out the differences.

At the end, Clinton (playing Rembrandt) and Cleavnt (playing Rembrandt-2) are standing together.


Then Clinton/Rembrandt runs out of frame, leaving Cleavant/Rembrandt-2 alone.


We go to a shot of Rembrandt, now played by Cleavant and not Clinton, saluting Rembrandt-2.

Then we cut to Rembrandt-2 and Rembrandt-2 is also played by Cleavant.


Clinton is removed once there's only one Rembrandt in the frame.

Good breakdown... helps me know what I was seeing. I think it's pretty easy to tell when it's Clinton.  Actually, now that I think back about it, I have noticed how well Cleavant plays the agent more straightforward than his remmy character to the point it's like two different people.

Regarding the STARGATE SG-1 blu-rays: I have only seen two episodes of the show (the first two, and on the blu-ray). But even from those, it's clear that distributor, Visual Entertainment Inc., didn't do a very good job.

I don't know the show well, but fan reviews remarked that on the box art, the Stargate is incorrectly drawn and that the cast photo uses a character lineup that was only in place for one season out of the 10, indicating that the distributor had clearly never watched the show -- which reflects their upscaling process.

VEI not only failed to improve effectively on SD video, they actively damaged HD video. Seasons 1 - 7 were edited on digital videotape. VEI upscaled them to 1080p, but their process was the equivalent of Topaz LQ, creating a clean image, but one that was also a bit blurrier than it needed to be. It would have looked like the 720p upscales of Seasons 4 - 5 where there was a bit of natural film grain on an HD-acceptable image. But then VEI ran the files through another round of image smoothing. Likely, they did this to avoid all the jagged edges that often show up in upscaled video files, but rather than do it selectively, they did it to every episode, adding another layer of blurriness.

It was probably unfeasible to watch seven seasons of TV to find the specific scenes that didn't upscale well, but then it would have been best left it alone and let some shots be flawed rather than adding further blurriness to all shots.

With Seasons 8 - 10, VEI ran their image smoothing process again -- which was nonsensical. Seasons 8 - 10 were shot on digital cameras; they were already in 1080p. VEI took sharp HD video and made it blurrier. The only reason I can see for this: one of their marketing elements is to declare that their blu-ray products offer a "Super Clean" picture, even if the image does not need to be super cleaned.

VEI also reportedly messed up the surround sound. Sometimes, enabling it on the disc turns it off while disabling it turns it back on, and it's completely random across each episode.

It sounds like a mixed bag, but also it does seem like some fans are happy to have that release. But it emphasizes my larger point -- I would be quite concerned about any party doing an upres or restoration without input from a party who is really going to try to help in quality assurance. These entities don't have the time to compare different settings for different things, they don't know the content, etc. They want to do a batch job.  They dont have the man power or time to sit through and rewatch everything.

I've mentioned in the other thread about my desire for Tracy to oversee a restoration process if the peacock gig doesnt happen and they could do a sliders special or roundtable alongside it.  Or something.  I was just saying that because I want someone on the inside who'd actually give a crap the way things looked.

The best way to really do it is get a scan on the 35mm from the studio and then handle the rest outside of that.  The post production.  That said, studios are big on not allowing anyone to change their content. I am not sure what deal VEI, had, and it's MGM that owns stargate i think but generally, i think even doing an upres isn't necessarily allowed for like a tv broadcast, but then again we suspected that may have been done by The Hub, so I don't know.

Point being studios tend to not want content altered.  Anyway, I think it's highly unlikely a scan of the original s1 film reels can happen, but i do think there's a course to make it happen.  It would just be hard to make happen.  But, you look at The Prisoner on streaming now, and it's like wow.  Why can't we have that? It'd be incredible to see Sliders the way it was meant to be... although I doubt it would have the color vibrance of The Prisoner. Not even Back to the Future seems to have that.


Back to SLIDERS: in terms of upscaling, Seasons 2 - 5 would look good if upscaled, but there will always be a certain haziness to medium and wide shots that separates true high definition from HD approximations.

There is one more thing I haven't tried with Season 1 yet. There was a fan upscaler who shared his process awhile ago. (He then went dark and destroyed all his social media posts.) His process: he didn't just use Topaz video upscaling. For numerous shows including XENA and LOIS AND CLARK (but not SLIDERS), he used Topaz Video to extract an upscaled version of each frame of the video masters (which he somehow acquired) and saved each frame as a PNG file.

Then he ran an upscaling process on each PNG file, apparently sharpening them up, refining all the details, and bringing the resolution to as high as 15,000 pixels tall. Then he scaled the PNG files back down to 4K or 1080. Then he reintegrated the PNGs into a video sequence via Premiere Pro and added back the sound.

I have Topaz Gigapixel for upscaling still images. But I'm not sure I would get the same results for SLIDERS as this fan upscaler had actual video masters whereas I have DVDs. In addition, I don't even know if these frames we're seeing can be upscaled because, as he explained his (destroyed) notes, the upscalers use grain and these Season 1 files are very short on grain. I'm also not sure if my external 1TB spinning hard drive and external 120 GB SSD are enough for even one episode of this increasingly over-the-top endeavour.

I've actually thought a little about this myself, if Topaz AI hits his limits, is upconverting with their photo software each frame a way to get even better quality.

The issue might be that the video AI may do something that's either entirely the same and breaks down all the frames and makes it a batch photoconversion job, or they have made some trade offs for processing time to get a 1 hour piece of content done.  I'm not sure how realistic speed wise it would be.  And you noted possible storage drive issues.

I'm also just not sure there algorithm is any different for photos vs. video.  I have used some AI photo things in the past on the web, and I have been trying to find them the past couple of weeks, but I can't find what i used. I wanted to try on a frame of sliders to see the results.  I suspect it may still have a hard time with the underlying content from s1.  But it would nice to be surprised.  In anycase, whenever I google, I can't find the ones I tried in the past (which were great back then). 

Maybe they were taken offline because they couldn't handle the cost of doing free photo demos for people.

here's an old one I did:

Open each photo in a new tab and flip between tabs to compare.  There was a fair amount of grain in the original shot, of course.

In the Pilot and "World Killer," Jerry O'Connell is interacting with a live person. His name is James Bamford, a stunt coordinator and body double. Jerry performed as Quinn in one shot with Bamford playing the other Quinn. Then they'd switch. Then they'd edit the scenes together, having recorded with a motion-controlled, motion-recorded camera so that the camera movements would match on both versions of the shot. Cleavant and Clinton should have filmed the same way, but in "The King is Back," an odd choice was made where Clinton played all of Rembrandt-2's scenes. Production should have had Cleavant film Clinton's scenes as well, and then arranged it in editing so that whenever Rembrandt or Rembrandt-2's face is clearly in profile, it's Cleavant's face and not Clinton's.

It took two-weeks to do that Pilot scene shot so I suspect they had Clinton play Remmy2 for speed/production cost purposes...

I have never been clear on why they used Clinton as Rembrandt-2. I wonder if some early attempt at DeepFake was in mind. However, "Post Traumatic Slide Syndrome" in Season 2 attempts DeepFake with the Professor and his body double and it's so bad it's funny; thankfully, Adam Nimoy made it a very brief shot blurred by motion. In "Greatfellas," Clinton and Cleavant shot each scene twice; switching roles for the second version, and then editing put it together so that Cleavant's face is Rembrandt and Rembrandt-2 and Clinton is always slightly angled away from the camera when his face is in view.

Really about Greatfellas?  Because I always felt I could tell the difference between the two actors...

In the pilot, even with the body double, there are scenes where both jerrys are in the same shot, and i think in the pilot commentary they explained how they did that.  Didn't they just superimpose the film negative over each other in that one?

*sigh* If SLIDERS had just been delayed by one year, Season 1 would be on digital videotape.

I've been watching some 2002 - 2008 episodes of THE DEAD ZONE on DVD. It's a DVD image and it's 3 - 4 episodes per disc, so the video quality is only adequate and a touch fuzzy, very much the average DVD. However, it was clearly shot on film (aside from digital cameras for some special effects sequences). And it looks like it was edited on high definition digital videotape, so that high definition video detail is still there, just muted by the reduction from high definition HDV to standard definition broadcast and DVD.

As a result, Topaz has absolutely no trouble restoring the high definition video quality of these episodes because it's mostly there on DVD, diminished but not destroyed.


A couple of ideas have come to mind.  There's obviously some of the dvd/blu-ray companies.. including the one that did the stargate bluray.  I'm gonna think more about that.  You'd essentially have to push someone at Universal to see the "bigger picture" of having an hd version of the s1 (especially if the show comes back), for global syndication (it's still in re-runs on occasion worldwide) and peacock, and then if you can find a blu-ray partner who'd pay part of the restoration cost (up-resed special effects of course)...

But that will be a little difficult to communicate / get going.

Another idea I had was.... well, let's say a SLIDERS documentary was being put together, and there was an inquiry to licensing the footage for use in the doc.  Let's say the documentary was aiming to be in all HD.  Because that's what distributors/streamers in the marketplace expect nowadays.  How much would it cost the filmmakers to get 35m scans of let's say 10 minutes of footage?  It's a way to see if they still have negatives, and how much maybe per minute an HD upgrade might cost.  Universal has an inhouse studio services division that would likely do the work for them-- this services team actually also works with outside parties on all types of content as well.

I mean one never knows, maybe there's an S1 blu-ray with a special documentary.

ireactions wrote:

I will actually run "Fever" through the MQ preset and share some screencaps. But until then, here's "Last Days" looking okay. This is the image once the compression artifacts are removed. Aside from that, it's just the DVD image with all its other qualities preserved at 1080p.

Even though s1 non-pilot doesn't get the holy grail out of this process, it clearly is a cleaner image, and more HD ready.

Strengths and weaknesses of the Artemis HQ upscale for "Fever"


I always thought Fever and Last Days were among the most crappy looking episodes in all the mediums (streaming, dvd, vod, etc).

When you look at those screenshots, do you think the HQ setting is definitively the best for Fever?  LQ hits waxyness too greatly, I assume?

ireactions wrote:

I think it might seem a peculiar proposition: of the 88 episodes of SLIDERS, 80 can be upscaled via plug-and-play, but eight need the original negatives rescanned. A distributor would probably elect to upscale all 88 even if eight would be below the standard of the rest.

They could do that... and I wish they would.  The issue becomes if they feel comfortable labeling a blu-ray as a blu-ray if it's all upscaled content.  How much precedence is there for that?  How do they handle.

I would love for Turbine or someone else to release an upscale. Or universal to do it.  That said, 65 hrs of upscaling is still somewhat expensive I think.  I mean off 88 episodes. 

So you got consumers who mostly don't want to pay north of 40 bucks for something.  Not many are willing to spend 150 bucks plus.  And yet the expense of upscaling everything... because machine time.

I don't really know how much it would cost, or if consumers would accept it as a blu-ray, or if they'd complain and you get bad reviews.  I would very much like to see a GOOD upscale job.  I think your samples for s2-5 people would consider mostly viable as 1080, especially because it is just so much better than anything we've had before, and s1 is still better as well, and the pilot is gorgeous.  But if someone does a shitty job, because they are lazy (that will be most production houses/distributors) than it's harder to market as a blu-ray.  I guarantee you would have done a better job on Stargate or some true fan of the content, because of LOVE.

I honestly never would trust universal with an AI upscale job or anyone else that we couldn't have direct contact with.  They would choose one standard setting, and push start. And that's it. Someone like Turbine would probably listen and be less lazy about it.

ireactions wrote:

Would you be inclined to look up the instructions and devise a process for DeepFake where we replace Clinton's face with Cleavant's in "The King is Back"? I have the hardware, but I lack the knowledge. We could post clips of all the Clinton scenes here; that wouldn't be the whole episode, just a selection to show proof of concept.

I don't have knowledge on that as well, but I assume they are mapping/scanning some celebs face, and then map the models face as well, and super impose.  I think there are cell phone apps that do this as well.  I will see what I can find, if there's any programs built for it.

I guess the Clinton's face bothers you but I kinda like it knowing it's another real human being in the same room rather than taking the same actor and splitting the image.  Although they did a great job in the pilot and world killer with Jerry on that.

I'd guess 12 per cent, mostly vortex shots, the spider wasps, the flood, the shark, the oil wells in San Francisco, Quinn's billboard face, the shot of the asteroid exploding from the missile and the birth control cola shot. Aside from that, I can't see there being much and the vortex is even more infrequently onscreen in Season 2; they sometimes don't even bother to show the sliders jumping into it one by one and just have the actors run offscreen. There's a peculiar irony to how SLIDERS at its most expensive had the fewest special effects whereas its budget overruns in Seasons 3 - 5 had it attempting as many effects as possible.

Interesting. . I was thinking it was a couple minutes of content per 43m episode.  We get our vortex shots but most of it is practical. As you said, s3 is where they ramp up that stuff.

12 percent would be about 4 to 5 minutes per episode.  You know the material better than I.

Well, without the billboard shots, the swarm, the flood, the shark, the oil wells and the asteroid, I would have put the effects at seven per cent (three minutes per episode). I'm just guessing. We could probably calculate it down to the second. It's only eight episodes after the pilot.

I wonder if at some point, we'll get software that can create computer generated models from the frames of the Season 1 episodes and rebuild the episodes as photorealistic computer animations that mimic the standard definition image but at HD levels. Alternatively, we'd just get better upscaling technology that can sharpen even without the grain.

One effect that I do think we could do as fans although I don't know how yet; I would like to use DeepFake technology on "The King is Back" and replace Clinton's face with Cleavant's.

I'd be willing to log the special effects shot for the stakeholders just as a proof that the series, while sci-fi, is not special effects dominant, and may not be an inhibitor.  I'd be willing to do whatever labor to cut down on there's.  I bet you would too.

I'm really interested like you where the up-res tech goes.  Has it platuted?  Or can it keep going further?  And is there any incentive for them to work on training models for visuals as fuzzy as the source content (s1) we are talking about? Or is it too niche for them to even try to address that use case?

I think trying to smartly add texture/grain back into the image, and then building off that gain might be a solution, but you also really have to figure out how to sharpen images/boundries without pixelating/jagging content.  You have to figure out how to condense blurred boundries and not sharpen areas that don't need the work.

I think it will be awful hard for anything to intelligently build/reconstruct the s1 objects/forms as they should be.  They may make some gains in wider shots, not bluring on people in the distance etc.

I've certainly dreamed of deep fake technology being able to make old characters have "new" content again... maybe in 25 years we'll be able to work with realistic character models of the sliders group and put them against backgrounds, and pull from an audio library of their words to insert sound. lol 

Here's the thing about Season 1:

Peacock would probably see a 2x lift in viewing numbers if they had S1 in HD.  Now how much add dollars does that translate for them?  I suspect it's not all that much.  I don't recall how many commercial minutes peacock inserts but they make about 10 dollars for every 30 second ad per 1000 views.  Let's say they get 25k streams of an episode at this point.  If they have 6 minutes of commercials, that's 12 ads, which is 12 cents per stream in revenue.  So that's $3k in revenue for that episode with 25k views.

If you double that stream total, it's another $3k in revenue.  Across 8-9 episodes, you are basically talking about a total additional $24-27k in revenue as an estimate for HD content, assuming S1 is HD.  It would have a halo effect on the other seasons viewing, so you can bump that to $35k.

I'm making assumptions of course, but it gives a general picture.


Now, $35k in increased revenue, may be $100k over a ten year span (sliders on peacock has only been on two years).

Then when you add you add $60-150k off a blu-ray profit, and increased sales on VOD, it sort of all adds up to some small justification for HDing a S1.  But barely, and not very clearly, and also, companies want to go after big opportunities, not small ones like this.  An upres is ballpark $~100k cost.

And it's tough because Universal's licensing group acts like its own company from peacock, and a peacock is seperate from a third-party blu-ray company.   So the benefit to take on the entire HD cost may not be clear for one individual party, but adds up for everyone collectively.

I was poking around and I noticed Stargate did a blu-ray release, and actually just up-resed some of the older content without re-scanning.  Some of the issues with the waxy look and lack of grain were there, but it's clearly better than the dvd.

I also noticed that company I linked to with iConform technology (to scan the negative and then automatically edit it together from a reference source) used the tech on a recent Baywatch Season 1 release.  They've also done jobs on the star trek and x-files blu-ray releases.

If Sliders really isn't that special effects heavy, at least for s1 non pilot, you almost wonder if it wouldn't be that much more work than what they did on Baywatch.  Grab some time codes for the vortex or the killer bees and insert upconversions on the special effects shots.  X-Files actually did this in some of their stuff.

I'd guess 12 per cent, mostly vortex shots, the spider wasps, the flood, the shark, the oil wells in San Francisco, Quinn's billboard face, the shot of the asteroid exploding from the missile and the birth control cola shot. Aside from that, I can't see there being much and the vortex is even more infrequently onscreen in Season 2; they sometimes don't even bother to show the sliders jumping into it one by one and just have the actors run offscreen. There's a peculiar irony to how SLIDERS at its most expensive had the fewest special effects whereas its budget overruns in Seasons 3 - 5 had it attempting as many effects as possible.

Interesting. . I was thinking it was a couple minutes of content per 43m episode.  We get our vortex shots but most of it is practical. As you said, s3 is where they ramp up that stuff.

12 percent would be about 4 to 5 minutes per episode.  You know the material better than I.

There's propertiery technology that is out there for scanning film negative and automatically re editing the content to match a reference source (an existing edited version).  It makes the process more manageable.   https://www.illuminatehollywood.com/services/iconform/

Special effects shots would basically have to be upconverted. 

I think the pilot and s2-5 can clearly be made into a damn good picture through topaz.  Non pilot s1 you've made look better than we've seen before with that tech but the source is still stubborn in pushing it further.

Theoretically with about 50 or maybe 100k I think ep 2 through 9 coukd be scanned, reedited snd have special effects shots inserted (upconverted from original source).

Would Turbine Media Group ever be willing to do a worldwide blu ray release for s1?   Would Universal keep the license to $100k to $200k or less?  With the idea that a partner who pays for that true HD content enable universal to then provide peacock and other partners HD for s1?

Turbine or let's say Shout Factory may say they need some exclusive window for the Hd content.  So what can they do in sales?

I am guessing globally we are talking 4 to 10k units a s1 blu ray moves.  At 15 dollars or off per unit that is $60k to  $150k in revenue.

It's tough.  Not a lot of wiggle room. 

If I were ever rich I would throw money at it myself...  spend the 100k to try to get it done.  If only we had some ability to raise a crazy amount if money like those Mystery Science Theater fans do.

Aside from the pilot episode, out of curiosity, what percentage of shots in s1 would you say have special effects in them?  I have a guess in my head but don't want to influence your answer.

This is how "The King is Back" looks after the HQ preset takes the Universal version to 1080p. I guess we have gone from VHS quality to adequate DVD quality.

Probably the most reasonable-to-watch image on a hdtv we have seen. And better than is out there commerically.

The source is so compromised that it would be hard to imagine being able to make the image crisper.

If I was putting this out on peacock I might tinker with the the coloring a bit. I might also try to see if adding any additional sharpness would be tolerated but I suspect not.

I feel safe buying anything off eBay because eBay clearly has zero support for sellers and is clearly eager to take any opportunity to refund buyers, but I can see how this system could be abused by buyers.

Yea there as some abusive buyers from what I understand but it's probably a one percent or less incidence rate.

I once got screwed by a merchant as a buyer.  I never took it up with eBay support.  Waited too long.  I thought he'd act like a reasonable person but it's incredible the things people are willing to justify themselves.  I am sure that happens with buyers too who decide they don't want something.

Here's another question to which we may or may not ever know the answer:

What do the NTSC video masters of Season 1 look like? Is the quality the same as my deblocked, decombed/deinterlaced Universal DVD files? Or are the NTSC video masters better than that?

(They probably aren't worse.)

We know from the German blu-ray: the PAL masters of Season 1 are blurry and the colour is washed out. It looks like the NTSC videotape was copied onto PAL format videotape, stretching the video and converting the NTSC colour to the PAL standard. 

A 20 per cent increase in size doesn't create that much blurriness in a digital format; it must be the analog duplication process back in 1995 when Universal was preparing for overseas broadcast.

The PAL masters for Seasons 2 - 5 are crisp and detailed, likely because digital videotape duplication retains fidelity and can withstand a 20 per cent increase in size.

All the post-Pilot S1 episodes on the DVD are fuzzy. I used to think it was overcompression. But the blu-ray has the same problem and to a greater extent. The Pilot on blu-ray is blurry compared to the Universal DVDs, but the rest of the Season 1 episodes are even blurrier. That's the PAL master. So what does that NTSC master look like?

I think it's likely that the NTSC masters of the post-Pilot S1 episodes are at a lower level of sharpness than the Pilot and Seasons 2 - 5. But how much lower?

In other news, I recently put my gaming laptop on a stand and directed a small fan at the underside for additional cooling as I upscale Season 1 of SLIDERS yet again. Is this the fourth time? Fifth? Sixth? Will this ever end?

lol

Who knows, maybe at some point we can ask Turbine to do an SD on Blu-Ray for the North American market, where they can get their hands on those NTSC masters.  And quite honestly, if they ever did, with some of the knowledge you've picked up here, if they were willing to try to upconvert the stuff to 1080, it might help.

I'm not sure though the demand is great enough for a Sliders blu-ray on SD for the north american market. It would have to look really really good to attract hard-core fans to re-buy.

One thing I really do love though about the blu-rays though is how many episodes they can fit on disc.  It's a lot more user-friendly than other home releases.  I wish they had a "play all" button though.

In my original upscales, Artemis Low Quality would smear wide shots, especially wide shots with human faces. The Universal DVDs were covered in compression artifacts, so treating it as low quality video seemed best at the time. I limited the upscale to 720p to minimize flattening out the detail in the image.

However, I think Artemis LQ is really meant for cleaning up video covered in compression blocks, video like late 2000s YouTube video at 360p or digitized consumer grade VHS. The resulting Season 1 upscales on LQ were a step up from the DVDs, but still very blurry in addition to being smeared. Seasons 2 - 3 came out well but a bit airbrushed and suffers a bit because it's 720p and the TV has to upscale it by another 50 per cent. I should have upscaled them with the HQ preset to 1080p.

Ok. I ask because it would seem like if one were to make the perfect restoration (absent of anything but dvds), that, theoretically (i only mean theoretically), would S1 (not pilot) be best on LQ for close shots, maybe MQ for medium shots and HQ for wide shots (and maybe medium)?

Out of curiousity, does the LQ setting work best for non-pilot S1 episodes on close-up shots, and the problems it introduces only come when the camera is more zoomed out and there's less fidelity in the image to work with?  You may have already addressed that here, but I dont recall.

I've never seen that episode look that good...

ireactions wrote:

I'm not sure what you mean. Noise layers are pretty common in video editing software. The problem is that unless the noise is image-forming, it's useless for AI upscaling. Topaz can tell the difference between grain that forms the image and grain that's just a layer on top of the image.

Yea, I was saying it would be nice if there was an AI tool that formed grain around objects rather than flatly across the image.  The link I pointed to I thought may have done that (for photos) but I could be wrong.

Torme is nice to fans. I'd agree with that.

However, I haven't seen Torme give away his writing for free -- nor would I ask him to, nor would I hold him to his past promises to do so. I don't expect plumbers to fix my pipes unpaid; I don't expect technicians to repair my fridge for a thank you. If Torme's pilot pitch is rejected, I wouldn't expect him to put his pilot script on the internet. It'd be nice of him to do so, it'd be welcome -- but I wouldn't find fault with him preferring to keep it to himself, conceivably to repurpose the ideas in some other project he can sell, etc..

Agreed.  It's not anything I certainly would expect or think he somehow owes anyone.  What I'm getting at though is I think he might have interest in doing something informal like that under the right circumstances.

But it's something that only really becomes relevant if his talks with universal don't lead to anything.

I think the first couple of seasons were tough for tracy but season 3 and dealing with peckinpah is what was really something that was hard and was the lasting taste he had.

Tracy is indeed very fan friendly... just today he did another episode of "The Prisoner" rewatch with a podcaster on youtube who is a sliders fan.

I also noticed how he said he'd never do a woke version of Sliders or something cookie cutter to chase where hollywood is going.  I don't think he's at a stage in his life where he's driven by money, and I think moreso just interesting things.

He does have a fully written pilot he did for the pitch so maybe if there's not a go, he'll find a way to get it to a sliders fan site, as he's shared some of his other concepts in the past.

ireactions wrote:

Season 2 - 5 episodes are sharper because they were edited on digital videotape with 540 lines of resolution.


Theoretically, if Universal ever wanted to make Sliders look better, but didn't want to invest much money or time into that process, I wonder if making use of the DV tapes for S2-5 would be fruitful.  Because, in theory, they had 540 lines (near native PAL quality) to work with and then striped away 10-15 percent to get down to 480. 

I don't understand the post production process well enough... I am assuming edited on DV does not mean that all the sound and visual effect elements are a part of those dv tapes and it'd only be incorporated once on SD 480 tape.

But Season 1 episodes on DVD, despite being less blurry than on blu-ray, are still severely denoised. The video files lack the grain needed for AI upscaling to re-render the files to a better level of picture quality.

Anyway, Cabby I don't think Tracy has trauma from the original run of the series.

I say it for a few reasons but if you've heard him go into details either peckinpaugh stuff, that was really hard for him.  Tracy isn't a type A personality like a lot of showrunners, at least back then, could be. In other words he has less asshole in him, and it didn't always do well with power accumulation or jockeying in those environments.

I think the experience was frustrating for him but once it got to peckinpah and the guardian, that's when it became super personal.

I have heard some more stuff from a former crew member helping shape some of my thoughts here but I want to leave that out.

As far as sliders coming back, I think we all know it's pretty unlikely.  It would be great if peacock took a chance but... well you know.  It's not like 2012 or even 2015.  It's 2021.  I hope to see it but won't get hopes up.

What has been beautiful about the last couple of years has been seeing bitter JRD talk nicely about sliders again.  Ask for fans to help and even emailing the CEO of universal himself. 

It's been nice to see Sabrina positively acknowledge it.  After she went through her own trauma.  I don't think she had good feelings about it for awhile.

It's been nice to see Jerry and his revival attempts.  And seeing him get together with Cleavant again to talk possibilities.

And it's been nice to see Tracy not just look at all the bad stuff but be able to think about the good stuff. 

So in some ways we've had a little revival.  If the group ever sees the probable writing on the wall (that universal won't green light them) i could see them willing to participate in something Tracy has written and put together with no character names or show title... and just released for the fan groups.  Sound effects on an audio drama doesn't take a genius and they can easily record dialogue on a cell phone mp3 player in an hour.  Send a quick email from LA, New Zealand, Africa/Canada. 

We don't need it but if Tracy had someting written or in mind... everyone might as well do it.

Then again maybe the actors would be more by-the-book than I think.

Anyway it's just an idea smile

Well, looking at the un-upscaled files direct from DVD and the blu-ray:

https://i.ibb.co/9thLTdQ/01.jpg
https://i.ibb.co/BBB5pBT/02.jpg
https://i.ibb.co/kxFHbkW/03.jpg

The Pilot on the blu-ray is blurrier. And the problem seems to be specific to the Pilot. It looks like for the PAL master of the Pilot, Universal took the NTSC version and simply stretched it from 640x480 to 720x576, meeting the PAL standards but losing image quality.

I'm currently finding it difficult to tell if the other Season 1 episodes suffer from the same problem. They are slightly better on blu-ray than on DVD, but it's possible that the blu-ray versions are only improved because they're not as compressed and have also been stretched from 640x480 to 720x576.

But it's just as possible that the Universal DVD versions have, under that compression, better (but still bad) versions of the Season 1 episodes and those are the files I should have upscaled to HD via the Artemis HQ preset. They looked okay (but not great) on Artemis LQ but the blu-ray SD-files were were smeary and awful after Artemis LQ. Maybe the DVD files are a better starting point for Season 1 with two Artemis HQ passes, one to de-artifact and one to AI upscale.

However, Seasons 2 - 5 blu-ray versions look good and have more film grain than the DVDs, so if they were stretched, the videotape image had sufficient film fidelity to withstand it and not suffer for it.

It would not shock me if the blu ray was simply better because of less compression.

Occam's Razor would perhaps point to that.

Overall the pilot from your up res samples was quite beautiful but the other s1 episodes certainly didn't reach the same standard as the other episode samples and maybe a different VQ setting would help with it. But it's hard to say because it seems like those s1 episodes need quite a bit of AI help and so it's hard to imagine the hq setting would be right for them.  Doing two passes though might be an interesting experiment.

the Universal upscale with the lq setting is clearly better there...

ireactions wrote:

Well, the issue with the low and medium presets: they remove compression artifacts but add additional pixels to the grain and smooth it out, creating an overly airbrushed, waxy look to the picture. I'm not entirely sure what the results will be if no additional resolution is sought. The idea would be to remove all compression artifacts while leaving a grain-equipped image that Artemis HQ can bring from SD to to 1080p, and it's possible that the results would be better as the algorithm wouldn't be trying to work around compression artifacts on the second pass. But it's possible this would produce the same results as a single pass on the HQ setting.

.

I noticed on your up res sample of the pilot from February that the waxyness was less of an issue when there was a zoom/crop to get to 16:9.

Theoretically you might be able to produce more natural grain by taking the up res at low preset, and then doubling it in size without any AI doing smart resizing.  I don't know how you'd do this though or if it would really give you the grain you want.  I just know the up res looks much more.like It was shot on film when zoomed and cropped. There's more texture.  An additional up res on something like that with us preset may be useful.

I think that as fans, we have accomplished anything and everything that could possibly be achieved with SLIDERS via unofficial fan works. We don't have fan films, but we have fan scripts and fan novellas which, given our numbers, is very impressive.

At this point, if SLIDERS can't come back officially through Tracy, we don't need to do anything more. We don't own this property and we can only steward it to an extent and we have reached that upper limit and surpassed it by now.

It's really up to Tracy and NBCU at this moment in 2021; our patronage has taken this TV show from 1995 as far as we can without actually having a TV show.

I don't think we have to do anything more but my sense is all the creatives involved would be up for it.

It took a long time for Tracy to get over the trauma he suffered on the original series and how he was marginalized. But all the cheerleading from fans, from John, Jerry,  cleavant.. I think allowed him to move back into a creative head space around it and push some of these issues aside and feel good about the original sliders core.  I also think JRD coming around and even Sabrina developing some good feelings lately indicative that they appreciate what they achieved, they appreciate each other and they appreciate the fans.

And Jerry would be up for something like that if he knew the doors were closed.   I think they all would want to give the characters and the fans a proper and deserving send off.

So yea it's not so much about what we as fans need to do to create content but I think this time it's about recognizing the feeling that all of the original creatives have and perhaps suggesting an outlet to channel it.

I feel like John, Jerry etc might look the other way and do it on "the low" and Tracy might want to do it because he has always appreciated how fans have stuck with the series to this day.  If universal says no he frankly might feel it's something he can offer (like he almost gave earthprime a story a few years back).

I don't think we need this but if they'd like to do it then it would be cool to do.

Regarding the upscaling process -- I got some nice results from AI upscaling the BIRDS OF PREY DVD's TV pilot with the HQ video preset. Most of the compression artifacts are gone and the grain remains -- but blurred out backgrounds still have a certain flickery blockiness to it. And when upscaling on the LQ preset, everything looked great but a bit too smoothed out. I'm wondering if a two pass approach is best: use the medium quality or HQ preset to deblock/de-artifact the video without increasing the resolution at all, and then run this new version through the HQ preset to bring it to 1080p..

Perhaps even low then high would work if it could find enough grain in that smoothness to work with.  But I assume you are suggesting medium as a middle ground

Anyone see those star trek fan films?  Jon Povill even wrote and  directed one of them.

I'm starting to think it's time to do a Sliders return "off the books". No use or the title Sliders.  No use of even the character names.  But a script written by Tracy, audio recorded on mp3 recorders on ones phone by our core four all from their homes around the world.  And produced by fans into a 20 to 40 minute audio drama in which the sliders get home.  Universal wouldn't come after it if it was just informally released on sliders social channels.  I think the actors would do it for the fans. I think Tracy woiud consider it as well. 

This assumes of course universal gives Tracy their pass on his discussions with them on a revival series.

Well, I would describe myself as a 'purist' of sorts in that I like film grain. And I sought out HD versions of the STAR WARS series without any of the 90s CG revisions.

However, having reviewed the SLIDERS PAL masters obsessively and intensively, I am no longer certain that the washed out look of Season 1 is in any way 'pure,' in any way faithful to the intention of the directors, cinematographers, lighting technicians, editors and storyboard artists (unless their intention was to create a fuzzy, out of focus, blurry storytelling product in a visual medium). I would support increasing the saturation to make it more suitable to HDTV presentation.

If we could just find some way to sharpen up these masters...

Either the AI technology gets better (it will I think) or we get a film negative scan would seem to be the only options.  Unless a re-scan of the master tapes would somehow help (and Turbine never did that themselves).

The machine time is what is expensive for any of these organizations.  You know the hell of video processing, and they are often thinking about the same things, I think.

I've been revisiting the upscale samples a bit this weekend, and actually figured something out I hadn't before. When I connect my pc to my tv, I used the tv's PC mode instead of standard for the picture quality. It did something that made the colors pop more... might be a gamma change thing. I've already got some changes to the image in vlc player I had told you about before.

The changes with PC mode made everything look gorgeous and lively and made the show feel newer and more modern.

I'm very, very, very mildly torn on this.

On one level, I think it's ridiculous to think that a TV show made decades ago can ever be made to look 'modern.' I also have a certain low level exasperation with 70s and 80s young adult/middle-grade novelists Lois Duncan and Gordon Korman who would, every few years, revise their novels to replace teletypes with fax machines and outdated musical references with current hits -- all of it completely pointless and futile. Stories set in the 'present' eventually become period pieces; the plots of PRIDE AND PREJUDICE and ROMEO AND JULIET would not happen with instant messaging and cell phones. It's fine for art to be a product of its time.

The poster child for futile efforts to keep dated works looking 'modern' is George Lucas and his asinine Special Editions which tried to make STAR WARS look like it was filmed in the 90s but only ever looked like a 70s/80s movie series with 90s effects clumsily pasted on top of the frames. These older films and shows and novels don't need to be forced into relevance for a new audience; they found their audience when they were originally released or they failed to do so.

But all you're suggesting is increasing the colour vibrance. I don't think it's harmful to SLIDERS, but I do feel that the low contrast, low saturation look of Season 1 is effective. Parallel worlds don't look like fantasy environments nor do they look like the overpolished TV commercials that Season 3 of SLIDERS often resembles. It's not a theme park version of reality; Season 1 looks like actual reality. Reality can be drab, lacking in rich colours, unpolished and that makes Season 1 all the more real.

And yet, this is instantly undermined with Season 2 which goes for a high contrast look. The colours aren't artificially amped up like in Season 3, but the increased contrast means more saturation.

Season 2 is my favourite visual look for the series with some real effort in making the image more delineated in terms of light and shadow. This is distinctly less unmodified than Season 1. So yes, Season 1 does look great when you raise the saturation a bit. And it would be great for an HDTV presentation.

This leads to another question that may or may not have an answer: is the gray, washed-out look of Season 1 deliberate? Is this actually what was intended by cinematographers Glen MacPherson and Peter Woeste? Or is the lack of colour a failure of videotape? Did the 35mm film, when transferred to what looks like a 240 lines of resolution tape format, lose colour detail and richness in the process? The fine detail and film grain of the image has clearly been muddied; has the chroma data also been diminished by the videotape format as well?

There is no way Season 1 was meant to look like it's in perpetual soft-focus like it does on the PAL masters. So was it also supposed to look like it was desaturated to gray tones?

If Season 1 had been edited on DV instead of U-Matic or such, would it look like Season 2? Was Season 1 actually supposed to look as high contrast as Season 2?

I don't know.

You could say I'm definitely not a purist, but I do empathize with Star Wars fans.  I think originals should always be accessible...

That said, in this case they are.  Via DVD.  And with Sliders on a service like Peacock, that should be appealing to a broad audience, and not the purists.

I don't mind tinkering with the original intent of cinematographers here, given that whatever look they have been going for assumed better conditions, and the content airing on SD.  Everything now is interfering with the look they hoped to achieve, so it basically doesn't work under the current conditions.  And yes, I think additionally their vision got out of whack anyway with how the content was maintained/produced. 

Plus, frankily, when you have some dated looking elements (most apparent in the pilot, with the wallpaper in quinn's home, or the wardrobes, or wade's look, or the computers..), you have to try to make sure the material looks more newly shot or the age of the program feels more out-of-date.  Stale.  If the picture looked as good as The Prisoner, let it be a period piece... but it can't even show the period with clarity.

i'd also argue for a peacock, the content should perhaps be dynamically cropped to 16:9.  It's 2021.  Look at how HBO Max takes pride in their library.  Sure's it's archival stuff but give consumers a half way decent experience, not just the schlock Universal sends you.  Even Seinfeld is cropped.

I'd love to see Tracy oversee somesort of upgrade, or restoration for Peacock.  Let him decide.

My hypothesis is that the Pilot was also edited on a lower grade of videotape than Seasons 2 - 5, but the format was still better than the post-Pilot S1 episodes. I'm thinking that the Pilot was edited in Betacam SP or some other format with about 340 lines of resolution. That could be why the Pilot looks approximately 20 per cent less sharp than, say, "Into the Mystic."

The post-Pilot S1 episodes seem to have been edited on tape with even fewer lines of resolution, likely U-matic, Betamax or 8mm videotape (250 lines of resolution) which would explain why those episodes look only half as crisp as S2 - S5 episodes. And I would guess that from Season 2 onward, the show was edited in a DV or DV equivalent format with around 540 lines of resolution which is why the film grains are so visible afterwards and why the image quality takes such a drastic upswing.

Makes sense. They really had some unforgiving formats back then... the fact that it went to 250... well, it was fine for those sd tvs but obviously awful for now.

Why do you have so many TVs!?! :-D

The 2004 release was made for CRT televisions. The Mill Creek release was not really made with any thought to how it would be viewed; it was just to have bargain bin product to sell. I sometimes wonder if modern HDTVs should offer a diode/scanlines filter for older content.

It's curious. On the whole, I find that the blu-ray's SD episodes for S2  - S5 look better than my upscales. However... the pilot is an odd case. My upscale looks better than the blu-ray version; the blu-ray version is a bit fuzzier and less defined than my upscale (made from the Universal DVD). The pilot is the only upscaled episode I still have on my hard drive.

Comparing the Universal DVD's pilot to the blu-ray version of the pilot side by side -- I'd say I find the Universal DVD a bit brighter, almost like during the scan to MPEG for the DVD, Universal's home video department brightened the image slightly. In contrast, the blu-ray version, taken from the PAL master, is a bit darker and has less apparent shadow detail. My upscale looks better than the blu-ray, but I'm going to try upscaling the blu-ray's pilot tomorrow just to see what happens. I can't do it right now, unfortunately, as I am re-upscaling BIRDS OF PREY's pilot episode with the Artemis HQ preset.

Modern tvs really should have an SD mode but then again maybe this is such a small use case.  It's just ironic situation.

I haven't compared the universal dvd vs. turbine blu-ray on the pilot.  I will say if I was ever put in charge of a restoration project, I would tweak the colors on almost every episode.  Not necessarily just to match the original intent (which could have lost some color as it was transferred/edited) but also to make it seem like it was shot more recently.

I usually thought the coloring was pretty good on the dvds/streaming S4/S5 content but veered toward dated as you go back.  After my changes to the pilot, with the up-res, it was pretty convincing to me that peacock could have a version of sliders that a 15 year old could enjoy and experience for the first time because it's much more watchable.  It felt HD or like a remastered scanned from negative thing.  Surprisingly, not that far off from Back to the Future (1986) blu-ray.   The only clues with the better look Sliders to the dating of the show are the cars and clothes but it doesn't ruin it.

A 16:9 image helps but I dont know how you can do a crop that isn't dead-center all the time. It worked for the pilot (though wasn't perfect and made all the shots more intimate) but you'd want to dynamically adjust it to make it work better in other episodes.

It can be pretty frustrating that a older shows look far better than sliders... I was really surprised how incredible The Prisoner (streaming on IMDBTV and amazon prime) looks.  Obviously filmed and edited on 35mm.

I was rewatching "As Time Goes By" on the SD blu-ray and I have to say, in my opinion, my upscaled version really does not compare. The SD blu-ray lets you see all the weathering on Dennis MacMillan's face and the texture of Quinn and Daelin's flannel. The upscale was smooth and attractive, but overly airbrushed.

However, I think it was also a mistake to use the Artemis Low Quality setting on the upscale; the Artemis High Quality preset would have cleared away the blockiness of the DVD compression but left the film grain texture and the fine detail largely intact (although it would still seem a slightly more airbrushed). I think the Low Quality setting is best for deblocking severely artifacted video (like on the Mill Creek discs), but the Universal DVDs were not as bad as that.


I'll do a comparison of the hi res sample vs. turbine release to see the difference on my end.

I've been revisiting the upscale samples a bit this weekend, and actually figured something out I hadn't before. When I connect my pc to my tv, I used the tv's PC mode instead of standard for the picture quality. It did something that made the colors pop more... might be a gamma change thing. I've already got some changes to the image in vlc player I had told you about before.

The changes with PC mode made everything look gorgeous and lively and made the show feel newer and more modern. 

This doesn't really do it justice but here's a cell phone pic

The other s1 episode samples dont look like this of course, but it was pretty incredible to see the pilot look this good. I cropped it to go to 16:9.  Some of the smoothness qualities you mention actually become less apparent when you zoom/crop (and you get more grain).  Although I think the pilot may be more forgiving w/ regard to cinematography than others (say Murder Most Foul, which didn't quite do as well with cropping).

I also have noticed, the old dvds, even mill creek don't look bad on SD tvs.  I have one, a tube 13 inch... wish i kept a larger sd tv I threw out last year.  I think a lot of these dvds have always been decent for SD tvs, it's just when you bump to HD tvs do they become problematic.

Thank you.  That's quiet different... Maybe your PC and player are processing the data better.

I just checked some more episodes and honestly not seeing it. Maybe Goodfellas was handled differently in the original editing / post production.

Even darker lit parts of The Good, The Bad and the Wealthy don't have the issue.

Here's what I mean regarding pixelation (Goodfellas).  Not really seeing it in "Rules of the Game"

In some cases maybe it's just upscaled grain.  In other cases not really sure what's going on. 

The universal dvds are just more "hazy" where it fails where in this case it's sharper and more boxy/pixelated.

Revisiting this, it's apparent this is not necessarily an issue everywhere.  It's most apparent in low-light situations, perhaps just early seasons, and perhaps also influenced by motion.  I'm looking at greatfellas which has darker scenes.

I'm not sure if its grain, but it may be partly that. So not sure if my initial description was accurate.

Well, I've run a few Season 2 shots through Topaz' high quality preset and it is recognizing those square-looking bits of data as grain. When upscaling the shot from 720x576 to 1474x1080, that graininess is resolved into pixel-rendered detail.

Topaz seems to be able to distinguish between digital noise /compression artifacts and image forming grains. At all presets, image forming grain is resolved into pixel rendering. At presets for low and medium quality video, digital noise and artifacts are filtered out; at the high quality preset, digital noise and artifacts are ignored.

Btw pretty interesting thread here started by turbine

On balance, i'm glad I got it.  I'd rather own a copy with files that have the best resolution that we know in existence.

It's really a beautiful release from a packaging / menu standpoint as well. Maybe one day we can push Turbine to do an "upconverted hd blu-ray" although they probably wouldn't bite.

I wish we could take a look at the image The Hub had again as they may have done upconverting on that.  I do recall it looking good.

The pixelation is actually film grain. I don't believe it has anything to do with Turbine; it's the film stock. I don't think PAL is grainy in itself because the post-Pilot episodes don't have this graininess which means that Topaz AI can't properly upscale them.

I wonder if some dvd players process the pal to ntsc conversion better.

I am very, very, very sorry for recommending a home video release that I now see has issues in being enjoyed by North American fans with NTSC hardware. I did not realize this would be the case as I didn't experience these issues myself, but I clearly got lucky. I am going to re-update the information in the first post of this thread with warnings about the PAL format.

I just did a comet vs. german release vs. original up-res samples comparison on goodfellas.

then universal dvd Rules of the Game vs. german release.

On the dvd/sd on blu-ray comparison, there was a clear advantage to the german release.  The universal release had a comparative noisy haze over the entire picture.

On the greatfellas comparison, the upres blew the german release out of the water.  The german release was an order of magnitude better than comet.


it's difficult for me to say if the german release looks better than peacock on goodfellas.  Close ups may be better and peacock seems to have more of a greenish hue to the image (i think) but on farther shots there is a far amount of pixelation on the german release that is smoother with peacock.  Then again, standing 12-14 feet, away the german release just looks better.

Yeah I'm watching Greatfellas on WatchComet right now. As bad it is, it makes the Peacock version look remastered in HD.


ha!

Got it working on another DVD player.  Certainly looks an order of magnitude better than the CometTV broadcast (happening now).

On a 40-inch tv, you can see the issues with the content upclose (sharp, pixelated noise on turbine vs a very fuzzy Comet image) but it looks pretty decent from 12-14 feet away.

I'll still have to compare against the universal blu-rays. I'm still hitting the higher pitched audio issue but I'm am not noticing the frame rate issue nearly as much.

Sorry to hear blu-ray playback is problematic. I have not experienced anything you describe, but I can see why some of what you describe is happening.

Turbine used PAL masters and is based in Germany, so their blu-ray is PAL. PAL video is played at 25 frames per second, but you may be using an NTSC player and NTSC is 30 frames per second, so your XBox may be playing the disc 20 per cent faster than designed and unable to sync the audio. That's also why the voices are sped up and high pitched.

Are there Xbox display settings to enable PAL framerates?

I'm not sure why my North American blu-ray player didn't have these issues; it was a bargain basement purchase. I'm surprised that it can accommodate PAL discs. My player has no upscaling whatsoever and my TV also doesn't have any upscaling aside from a noise reduction filter (which I've turned off). It is a monitor with poor speakers (plugged into a small PC subwoofer bought for $20 years ago).

I was happy with the Season 2 - 5 video quality, but I'm only watching it on a 55 inch TV (about one-fifth smaller than yours).

My external blu-ray drive was able to read the disc, but I've never tried to play the disc on my computer, just copy the files as MKVs for upscaling experiments for home viewing. The file framerate is 25 frames per second. Also, I've learned that PAL resolution is 720 x 576, that's why it's higher than the 480i files on the North American DVDs.

I'll check re: PAL frame rates on the xbox settings and then see if i can try it on a couple of other blu-ray players to see if they handle it any different (assuming they can play PAL).

Perhaps the solution would be to rip the discs, then somehow convert it to NTSC but I assume I'd have to do it as non-SD files or the 576 lines of resolution might be bumped down to 480?

It is interesting your blu-ray player seemed to handle the frame rate thing better (and obviously audio as well).  Xbox's blu-ray player is supposedly really good for upscaling content but not sure about other aspects.

My german blu-ray came!

The packaging is very nice and the prints on the discs themselves are gorgeous.

The menus are also really nice.

Unfortunately, playing PAL didn't work on my blu-ray player where I have a projector.  So I tried it on an XBox.  Fortunately, Xbox played the episodes but I have to say I was pretty unimpressed with the image quality.  I had it on a good quality HD tv (about 70 inches) and it may be that it couldn't scale for that size well or the xbox's upconvertor on the blu-ray didn't upconvert pal format (or maybe because it was sd on blu-ray it didn't upconvert it like a dvd it would). 

I tried the pilot and the first episode of season 3.  The pal format actually caused the strobe / frame rate effect that you commonly see with some of the European shows played on PBS.  Weirdly, the english audio was blatantly out of sync in some spots (I wonder if this would happen on all blu-ray players or just xbox?) and the voices were a bit more high-pitched than i ever remember hearing them on other Sliders sources..

I'm gonna do a comparison against the universal dvds on that same xbox/tv to see how it compares as maybe I am being overly harsh.
