Can you do an 8K remaster of a movie shot in 4K digital? With film you can just rescan the negative with a higher resolution.

This will not magically make extra detail appear, though. Film does not have infinite resolution.

For instance, the ARRISCAN film scanner goes up to 6k for 35mm. They could go higher, but there's no point.

Yes? There's a ton of AI upscales coming out and they're becoming really good; plenty examples on youtube including iconic scenes from iconic movies. Perhaps another 12 months max before AI upscales go from enthusiast/amateur remaster community to commercial.

Having an AI generate 75% of the movie pixels that weren’t there in the original work doesn’t really count as a ‘remaster’ imo

It's what most of those "HD remasters" of film are doing. (Well, sometimes it's a human or a chemical/mechanical process rather than an "AI", but either way you're fabricating details out of noise and/or thin air).

I suspect that getting objective improvements from a 4K to 8K film scan would require extremely well-produced film and probably a large-format film like 70mm.
