Speaking of which, Nvidia has built-in live AI upscaling on the Shield TV android box. - Is there any stand-alone live AI upscaling / 'enhance' alternative for android or any other platform?
It’s pricey, and being so old, I fear it will soon be obsoleted…

YouTube tends to post a downscaled SD version first, then they encode and post the higher-res versions when they get around to it. This can take days in some cases. Meanwhile the creator catches the flak...
4K processing takes just minutes, but HDR processing can take over a month to… never. There is no indication of this at all, no progress bar or eta. Just check manually every few days! This is why everyone is giving up on HDR, it’s just too painful because the content distributors are all so bad at it, with Netflix being the sole exception.
So now we need to stop making fun of cops pressing the "enhance" button in films...
I recently had some old super8 films shot by my parents scanned into 1080p resolution in ProresHQ. Because of the poor optics of the original camera, imperfect focus when shooting, poor lightning conditions, and general deterioration of the film stock, most of the footage won't get anywhere near what 1080p could deliver. What I'd like to try at some point is to let some AI/ML model process the frames, and instead of…
I also restored some Super 8 footage recently and had great success. The biggest win I had wasn't resolution, but slowing down the speed to be correct in DaVinci, and interpolating frames to make it 60fps using the RIFE algorithm in FlowFrames. I then used Film9 to remove shake, colour-correct, sharpen and so on. Correcting the speed and interpolating frames added an amazing amount of detail that wasn't perceptible t…

I'm a filmmaker... I don't know a single DOP or director who wishes they could work in HD but is limited by finances or knowledge. Again, shaping light is the essence of cinematography. Modern DSLRs far surpass the dynamic range (although not the effective resolution) of 35mm film. And yet the image they produce isn't comparable. When it comes to image quality, bit depth is enormously more important than dynamic rang…
Very informative comment! Could you please tell me what you mean by "effective resolution?" Is it the resolution in px or something to do with dynamic range? (I don't know anything about filmmaking.)

A bit of a let down that the video demoing SDR->HDR conversion is itself only published in SDR. Makes as much sense as demoing a colorization tool in a grayscale video!
If they were serious about showing this tech off they should've provided a video file download. Also indicate that it's a HDR file and should only be viewed on a HDR display. Youtube is just making this look bad as people won't see a difference.

An HN search of ''Deep Space Nine'' and ''Topaz'' will show some great discussions here covering the dearth of such upscaling solutions, as well as some huge efforts before commonplace AI.
I found this single discussion? https://news.ycombinator.com/item?id=19453745 And that's by avoiding the word "topaz", where I see no story results with discussions and not much of comment results.

Links to the artciles found in those discussions are to some very enlightening efforts by Joel Hruska to find an upscaling solution related to what the person asked about. As somebody else mentioned, Topaz is out there and Hruska gave it a good shot, but it is not open source.
The upscaling doesn't seem particularly convincing, however, the HL2 RTX video on the same page definitely is.
