STAR WARS: EP IV 2004 <strong>REVISITED</strong> ADYWAN *<em>720p HD VERSION NOW IN PRODUCTION</em>
Time

I’d agree that deepfaking fake wedge would be great, though I’m not familiar enough with the process to know how much work that would be. I’ve seen a lot of impressive deepfake videos but most still have noticeable artifacting, so I would only say it would be good if it can be done to a certain level of quality.

Star Wars Prequels 35mm 4K Filmized Editions by Emanswfan
Time

Just saw Once Upon A Time in Hollywood in 35mm this past weekend, and it was a really nice reminder to see how a modern 35mm print should look.

It’s given me a better idea of the look of modern film, and I’m confident I can truly master something close to that. What I do really struggle with is creating an authentic older look from the 60’s, 70’s, or 80’s. When I research for recommendations regarding emulating older stocks, there’s not much to find.

Also it seems that the projection I saw has more flicker, a softer look, and a warmer appearance especially in the skin tones.

Also here’s two more sources I’m wanting to use as reference. They have a very pure film look, something I want to strive more for. Even many movies shot on film today overdo it with the digital color grading that it ends up looking too similar to digital.

Gigapixel AI vs. infognition Super Resolution or What to use to upscale SD to HD or 4K
Time

I’ve been recommended by a smart dude something that may be even better: ESRGAN/BasicSR. It’s an AI-upscaling algorithm just like Gigapixel, but you can train it with your own datasets, so if you have a representative dataset of what you’re trying to upscale (you need high res and low res reference for training), you can get really incredible results.

I’m currently playing around with it, and while training is very slow (we’re talking many days), it’s impressive what it can do imo.

I’ve tried some pre-trained ESRGAN upscalers, and I’d say it is a more natural looking upscale than ai gigapixel, but I’d still say ai gigapixel wins in the detail, even if it looks a bit too sharp. And I’d still say in terms of noise reduction ai gigapixel and waifu2x are better at removing compression artifacts. Of course waifu2x doesn’t try and add or recover detail, but simply a high resolution upscale that retains all the original detail.

All three are really good tbh, and all have their purposes. I’d say a mix of them is ideal.

I turned down the denoising setting from full to half in gigapixel, and this is what I get. It seems full does smudge some fine detail, but no denoising keeps those hideous compression artifacts in, so this might be a better balance. Either way you can definately see the big difference that the software does to take highly compressed 1080p and transform it to uncompressed 4k.

Here’s six new screenshots from AOTC using the new HDTV source, denoising, and AI upscaling, along with the methods I’ve previously used. I haven’t put much work into the new grade yet. But goodness, I’m happy to not be dealing with the horrid blu-ray colors anymore.

I’ll post a comparison too once screenshotcomparison is back up (I can’t seem to get framecompare to work either).

Hey emanswfan, any chance of rendering up a full 4k shot of something with your film grain/grade applied? These upscales look promising but I think many of us would love to see what they look like absent that nasty digital sheen. 😃

For sure, I’ve just wanted to try out upscaling with gigapixel and esrgan which seem to be the best two AI upscalers, although they do bring weird artifacts that non-AI upscalers don’t have. So I’ll still have to figure out the best method which may vary from shot to shot, or a combination of several. Previously, I’ve also used Waifu2xPhoto (AI upscaler), Detail-Preserving Upscale (Adobe, non-AI), and RedGiant Instant 4K (non-AI).

For AOTC, I will now be using Schormann’s HDTV preservation over the Blu-ray It has the theatrical/DVD colors (which saves a hell of a lot of work not having to deal with shitty bluray colors) and once denoised to get rid of compression artifacts, actually carry over more fine detail.

Of course, there is the strong possibility of a 4K release by Disney premiering this November on Disney+, and later in May 2020 on UHD Bluray. These may look better in detail by them going back to the original files and possibly re-rendering VFX. Hoping though, that AOTC has correct colors, TPM isn’t poorly DNR’d, and that ROTS just stays mostly the same.

Proper filmized screenshots should be coming soon again.

Until I build my new computer next year, I’m pretty much stuck to doing tests and samples on my Macbook Pro, but I can at least save grading work as presets for future work.

Star Wars OT SE 1080p 70mm Filmized Concept
Time

Just thought I’d post upscales of the OT here as well. It’s been denoised and upscaled to 8k, although these are sourced from Adywan’s new 1080p ANH SE grade from last year. If I ever carry out an OT restoration, it’ll be based on the rumored upcoming 4K releases that I assume will debut on Disney+ in November, and come out on UHD Bluray May 2020. The project will be rendered out at 4k, but I may upsample to 8k and sharpen and denoise at that resolution, which is how I was doing this project previously. Of course I hope to be building a new computer next year and add plenty of hard drive space for my PT project, and this one if I decide to afterwards.

https://lensdump.com/a/anh-8k.W1ShD

There are some artifacts, and the denoising needs some tweaking, so very much see these as drafts. Also, I have not applied the 70mm regrain yet, as to show off the raw amount of detail added.

I may also try to mess around with squeezing more detail out of 4K77, 4K80, and 4K83 in the future, if I want to make the best out of the theatrical versions, assuming Disney doesn’t release official versions of the unaltered cuts.

I showed ESB Revisited to a friend a few days ago, and noticed the resolution more so this time than when I first watched it nearly two years back.

I have a 75" 4K screen and so it is pushing the image harder than most but I think the more our eyes become accustomed to watching 4K content the more you notice when the presentation is lower def. Just like the moment came to most of us who’d amassed an old VHS collection, where you’d take it to the charity shop because you realised you’d stopped putting the tapes in the player after becoming used to clarity of DVD.

Adywan, I don’t know if you’ve gone too far down the road with 720p to change direction now, but if there is the potential to use the 4K source for either SW:R or ROTJ:R then I think that would be really wise - as the ‘last gen’ feel of 720p is a gulf that is only going to increase in the coming months and years. I don’t think keeping them consistent with ESB:R is a good reason not to as has been suggested, as intentionally hobbling something to bring it ‘down’ to a lower quality would be self-defeating. Technology is moving on and the longevity of the Revisited project would be better served with 4K. At the time of their release fans may have to choose between watching the best edited version (Revisited) or the best looking version (4K), and it will be a compromise. Star Wars fans have long had to compromise on owning the version they really want, and it would be nice to have one that is finally perfection!

Adywan, I know you prize presentation and always have good reasoning, I’d be interested to hear your thoughts and the challenges around Revisited 4K?

I’ve been trying out upscaling the Revisited films to 4K, maybe you could check what these look like on your tv? https://lensdump.com/a/esbr-4k.AG8Hq

Speculation about the 4K Future of AOTC and ROTS
Time

Here’s an updated look at the HDTV master vs the Blu-ray:

Blu-ray: https://i.lensdump.com/i/WPdnTP.png

HDTV: https://i.lensdump.com/i/WPdvOm.png

As you can see the blu-ray smudges so much detail, and that once you clean out the compression artifacts from the HDTV master you can see all the missing fine detail.

So hopefully they will either make a brand new 4K DI with re-rendered CGI, and definately not an upscale of the blu-ray master.
