Ok, so here’s an 8K frame from AOTC without any regrading. This is a test of AI Gigapixel.

I’m very happy with these results, I’ve since fully revised my upscaling techniques.
Yes, there’s some haloing which I am trying to reduce for my next preview.
There’s also some relevant discussion here too for those who haven’t read: https://originaltrilogy.com/topic/Speculation-about-the-4K-Future-of-AOTC-and-ROTS/id/67513
Have you tried out AI Gigapixel? does great upscaling.
Just looked at it as well as the other products they offer, and it looks promising. I haven’t used one of their products in a really long time, but if it’s AI driven, it might be pretty good.
A little birdie told me the 70mm print is from 1984 so it shouldn’t have the fade…but it is definitely the original film.
So I’m guessing that means no original crawl tho? And would the mix be the same as a 1977 70mm print, or a more refined mix closer to the mono?
Wow, I am speechless. This is incredible.
That’s the only thing that sucks about me not working at a movie theatre anymore. One of my managers would always host after hours showings for all of us staff, and we’d pick a movie to watch. I told him about Revisited and Despecialized and he said we would do it eventually, but he ended up leaving around the time I left, so sadly it never happened.
This is a comparison between the Blu-ray and the HDTV preservation of AOTC both blow-up to 8k to see the difference in the fine-detail.
Apologies, for them not being the exact same frames, but it’s close enough to still work as a comparison.
So in terms of upscaling AOTC, I compared a straight lanczos3 4K upscale up against a waifu2xphoto denoised 4k upscale.
As you can see some objects scale well that already have sharp lines, but most of it is still a blurry mess and doesn’t look that much better. I used the maximum setting for denoising which cleans up all the image but does scrub away some detail. So essentially there’s no big difference.
The reason being is that the shot is already cropped in from the full 1080p output of the camera with poor upscaling, so the footage is already sub-1080p. George Lucas frequently cropped shots in, sometimes for a zoom effect. AI upscaling usually only looks good if the input is in it’s native resolution. If it’s been previously upscaled it blurs the input and the AI can’t find the edges and fine detail.
What might work better is a multi-frame upscale for each shot that accounts for details that change across the frames.
This video could be helpful for understanding some things. It doesn’t go into HDR as much as it should, but it does explain that our uscales usually use just one method, while the professionals use different upscaling methods per shot sometimes. So AotC/RotS would benefit from a professional upscale, not to mention the less-compression UHD provides AND wide color gamut.
This video does a great job at explaining things. I’ve been doing a lot of research into upscaling footage, and there’s a lot of newer algorithms that are pretty exciting, such as AI and neural network driven upscaling.
Even I’ve very much advocated that even SD material, like many shows shot in video prior to digital HD, would benefit from profesional upscaling and other clean-up. Doctor Who has been re-releasing their classic series on blu-ray and even those manage to get more out of sub-HD material and allow for a cleaner, less compressed image.

Eman, I’d be curious about your candid opinion of the HDTV master we have from schorman13 for AOTC. Head-to-head, how does it do compared to the BluRay?
You know I actually haven’t seen it yet, I was at one point considering switching to it as the main source for AOTC considering it has the theatrical colors.
I’ll take a look at it soon, and get back.
The color balance was shifted warmer and more pink to compensate for the teal shift introduced on the Blu-ray. I could grab probably grab an HDTV rip or my DVD for reference to make it just right. I think I still need to figure out more adjustments to match the visual quality of ROTS, let alone the new films.
While I was working on upscaling the existing blu-ray of AOTC, I was reminded at just how god-awful it looks. There’s digital noise, compression artifacts, misaligned color channels, etc. ROTS is actually a huge improvement due to them using a newer digital camera.
So I’m hoping they really clean up the footage well, because it’s a pain to fix this.
This program I was planning on using if they don’t release 4K versions: https://www.videoartifact.com/va/
It can do some amazing stuff!
But I’d hope Lucasfilm can do better than me with cleaning up the footage.
Here’s a comparison of all the shots:
Here’s some AOTC shots testing out the new upscaling process along with an itteration of my whole movie grade.
I don’t like the color of every shot, but that is only something I can fix in my later in my shot by shot grade. I’m trying to come up with a consistent grade to maintain the original color timing with a filmic twist.
And also this is without film grain as to show off better the upscaling improvements.
Reviving an old thread here, but I’m planning to start up work on these edits once again sometime next year.
I’ve watched many prequel edits over the years, and while I enjoy a lot of them, I’ve still never been completely satisfied with any of them.
I’m planning on releasing two versions of the prequel trilogy films possibly. The first versions would seek to maintain much of the current continuity and feel like simply alternate cuts. Second versions will work out more radical ideas and take longer to complete.
I’ll be posting here some more as I come up with and gather ideas as I rewatch the blu-rays and other fanedits over the next year. There have been many recent ones I haven’t seen, so it’ll be interesting to see what other editors have done.
I’ll be simultaneously working on these edits along with my prequel regrades.
Emanswfan, did you create any LUTs of your Technicolor emulation? And if so, would you be willing to share them?
Not sure how I would create LUT’s for my color grades now with how I do them. Theoretically I could tho, as my intentions with Version 1 releases is to create a grade to apply consistently across the whole films in order to keep most of the original color timing decisions. I’ll look into it tho, as that may be a good way to get my work into some faneditors hands sooner.
Eventually I’ll have to do a shot for shot color grade, but I don’t think it’d be worth it till the official 4K releases.
But really, with my desktop broken and money being tight right now, it’s gonna be a while till a release comes out. My macbook pro which is my everyday computer is just too busy with other stuff, that I don’t have time to be doing long renders.
I’m expecting to save up for a massive upgrade in power for my next PC, which I’ll be building myself, and which can be used solely for my video editing and gaming purposes.
I’m also gonna transfer my hard drive from my old PC to recover any older work I did on this project.
I’m betting that in the new 4K release next year, they will have way more deleted scenes for the OT given how it’s been revealed that they’ve scanned all the original raw footage and have even shown some.
I’ve always wanted to see an extended cut of all of these films.
Plus, there’s still a lot of PT deleted scenes that have never been seen before either. And I’m crossing my fingers that we’ll get the DVD deleted scenes in HD.

Are you one of the twelve people in the world who actually owns a UHD optical drive?
Yep, I ended up upgrading to one of those considering my other bluray drive is internal and is in my currently dead PC that I need to either fix or replace.
They’re pretty much the same price as I paid for my internal bluray drive 8 years ago.
And to note the extra bit depth is incredibly useful for color grading work in fanedits.
I’ve run into many issues with regrading the prequels due to the limited amount available on the current blu-rays. Meanwhile working on Solo from the 4K Blu-ray, it’s incredible just how much you can alter the image.
As usual, your color grading is spot on and makes for a look that seems to retain the retro feel but still have proper colors.
And interestingly they make it sounds as if AOTC and ROTS are going to be native 4k masters instead of an upscale of the existing 2k DI’s. Of course the footage was shot at only 2k, but re-rendering the cgi and redoing the compositing would bring about a lot of improvement.
Also I would love if they would fix the color timing on AOTC. Trying to work with the god-awful blu-ray colors is not fun. ROTS has been the most enjoyable since the colors aren’t botched.
Also for the love of god, I hope they bring back the grain or redo the denoising for TPM. I’ve seen some extremely impressive denoising over at the 4K77 forum on SW and ROTJ, so I know you can denoise without making everything look waxy.
Hey, so I tried upscaling ESB:R to 4K. I denoised, upscaled, and regrained the footage all in After Effects.
Honestly, I still have to mess around with the denoising and regraining, both of which might be overdone.
So essentially it’s very much a work in progress, but I’m using the same techniques here as I have for my PT regrades.
I’m honestly gonna wait and see if we get 4K versions of these next year in a 1-9 boxset.
Working with Solo from the 4K blu-ray has been a much more enjoyable experience due to the 10 bit, wider color spectrum video source.
There are some ways of upsampling the footage to 10, 12, or 14 bit video and removing compression artifacts, but it’s very tedious, and I’ve only done it for small previews.
If they don’t make 4K releases, I’m going to try and decompress the footage as I have been but try using the photo mode on waifu2x to upscale instead of Instant4K which I’d used in all the past examples.
I know you’ve seen Revisited before, but just for handy, you should look through the changes gallery for Revisited if you haven’t:
I know your approach is more modern and radical, but there’s many changes I would say that are worth redoing for your project.
Also, I’m assuming you’re doing this project at 1080p? Just in my experience in working in 4K for my prequel regrades, it’s one hell of a hassle.
