I got to see the Band of Brothers C-47 take off back in August of 24. All I had was my 2018 cellphone, so the 60 second video’s quality was marginal. Here are some example crops from the video.
I tried to sharpen it up with Theia and after 3 and a half minutes it had finished with this result.
Starlight mini took 484 minutes to produce this.
Generally I like the improvement, I just wish it hadn’t distorted the invasion stripes and insignia star.
Try Proteus Manual with only Fix Compression turned up to anywhere from 15 to 40.
Well, I don’t know if that’s what you are hoping for. I think it looks a tiny bit better than the Theia result, but there’s not much improved in any of them from what I can see.
Try Starlight mini at 3x resolution.
Text and logos are handled MUCH better there than in 2x or even 1x.
Took your image u posted here and upscaled it with Nano Banana Pro from Google
I hope we get closer to this kind of quality upscaling in the next few years on PC 
I will wait till that time for restoring my old movies
Where you have D-Day should be the serial number 292847
Yeah, AI still makes many mistakes. The lighting by Nano Banana is also wrong, original is much more flat. But there are a lot of details which seem quite accurate and shows what could be possible if they are able to make those AIs more accurate in the future.
Atm, I almost only work on 1080p and 4k material with Topaz because it does a decent job for de noising and sometimes detail enhancement. But for lower quality source material Topaz is not powerful enough. Best image upscale AIs available today give sneak preview of what should be available on local PC in a few years.
Here I have an interesting example for face restoration
Here is the original where almost all details of the faces are lost (it’s from the british WW2 documentary ‘World at War’)
One version with reasonable face restoration which is far better than whats available in TVAI atm:
And one version which goes way too far and hallucinates a lot of additional details which is kinda fun but certainly not accurate:
