Hence why StudioCanal backtracked on a 4K upgrade of Irreversible once they realised that it was fundamentally a 2K digital work and that the only way of changing that would be to scan in the Super 16mm elements (assuming they survived) and redo literally all the extensive post-production - and in that film, there isn't a single shot that hasn't been digitally processed in some way, even if it's as basic as reframing it from 1.66:1 to 2.35:1, but in a lot of cases it's a lot more elaborate than that. (One of the film's most famous characters - the guy who enters the subway, sees what's going on and then beats a hasty retreat - was digitally added.)EddieLarkin wrote: Wed Oct 04, 2023 12:40 pm This is why studios (rightly) basically never try to present something in "trooo 4Kay" when they're dealing with a film that was put together digitally at 2K (or lower in this case). It costs a lot and the results can be terrible anyway, and revisionist to boot. It would have been a far better service to this film to simply go back to the DI and present it warts and all, gaining some small benefit from the superior formats that UHD offers.
And even if they were mad enough to actually do it, the visible difference would be negligible except to the most obsessive Caps-a-holic scrutineers. You'd be more likely to get people complaining that a new effect hasn't turned out exactly the same way as an older one.
(This is a perennial headache with turn-of-the-millennium films; there's simply not way of achieving a 4K upgrade without cheating in some way, because they were never designed at the time to receive such treatment.)
