I think you're missing the point of this paper—the precise thing it's showing is upscaling previously downscaled video with minimal perceptual differences from ground truth. So you could downscale, then compress as usual, and then upscale on playback. It would obviously be quite attractive to be able to ship compressed 480p (or 720p etc) footage and be able to blow it up to 4K at high quality. Of course you will have…

Why would you not enhance the compressed data?

In our hypothetical example, the compressed 4k data or the compressed 480p data? You would enhance the compressed 480p—that's what the example is. You would probably not enhance the 4K, because there's very little benefit to increasing resolution beyond 4K.

Once AI tech gets fully integrated, the movie industry will cease to exist.

Hollywood has incredible financial and political power. And even if fully AI generated movies reach the same quality (both visually and story wise) as current ones, there’s a lot of value in the shared experience of watching the same movies as other people, that a complete collapse of the industry seems highly unlikely to me.

Unlikely in the next 10 years or the next 100?

Not if there isn't coherency between those chunks

Easily solved, just overlap by ~40 frames and fade the upscaled last frames of chunk A into the start of chunk B before processing. Editors do tricks like this all the time.

And now you end up with 40 blurred frames for each transition.

Another boon for the porn industry

Why, so they can restore old videos? I can't see much demand for that.

There are a lot of old porn videos out there which have become commercially worthless because they were recorded at low resolutions (e.g. 320x240 MPEG, VHS video, 8mm film, etc). Being able to upscale them to HD resolutions, at high enough quality that consumers are willing to pay for it, would be a big deal.

(It doesn't hurt that a few minor hallucinations aren't going to bother anyone.)

I didn’t rate the film really, but loved the book. Apparently it is based on / taking style inspiration from real first hand accounts of ww2.

It’s style is based on the oral history approach used by Studs Terkel to document aspects of WW2 - building a big picture by interleaving lots of individual interviews.

Making the movie or a documentary series like that would have been awesome.

So sad they didn’t keep to the idea of the book. Anyone who hasn’t read this book you should, it bares no resemblance to the movie aside from the name.

I know two movies where the book is way better, Jurassic Park and Fight Club. I thought about putting spoilers in a comment to this one but i won't.

The lost world is also a great book. It explores a lot of interesting stuff the film completely ignores. Like that the raptors are only rampaging monsters because they had no proper upbringing having been been born in the lab with no mama or papa raptor to teach them social skills

The video comparison examples, while impressive, were basically unusable on mobile Safari because they launched in full screen view and broke the slider UI.

Yeah, and in my case they immediately went fullscreen again the moment I dismissed them, hijacking the browser.

Decent editors may try that once, but they will give up right away because it will only work by coincidence.

Videos autoplay in full screen as I scroll in mobile. Impressive tech, but could use better mobile presentation

Yup, same here (iPhone Safari). They go fullscreen and can't dismiss them (they expand again) unless I try it very fast a few times.

It's offtopic, but this is very good advice. As near as I can tell, there aren't any real similarities between the book and the movie; they're two separate zombie stories with the same name, and honestly I would recommend them both for wildly different reasons.

Funny - this is also a good description of I Am Legend.
