film grain is added in post for tons of modern movies. ANything with a 3d model VFX shot basically has grain added on top, unless it's spy kids 3D because it's not so great for 3D. film grain has a lot of practical applications and cannot be judged by a still. 1) it can unify the scene if you have multiple layers, VFX, or greenscreen. 2) It can increase the appearance of resolution where there is not enough to fill your medium (most optical transfers of film only resolve about 1.2K of resolution when there is at least 2K of resolution to pack in) It explains why that image above looks like it has no detail when it's been denoised. 3) it eliminates banding when you transcode to a 4:2:0 medium like blu-ray/DVD Also you cant judge it's strength from a still, When you see it in motion at full framerate, it's hardly noticible until you pause it But nobody watches movies a still at a time, so it's moot saying "look at how bad film grain is!!!!" from a still.

yes lets add noise in a codec thats fundamentally inept at handling high-frequency data like that xiph was playing around with a codec that would split out the noise and compress that separately, but it was hard to do the noise detection and removal in real time. worked very well off-line though, but couldn't be used for streaming, so they dropped it.

the problem is that with a film transfer, that grain is still in there (unless you removed it for some high end DI/VFX stuff), and so many DoPs are so adamate about keeping their kodak vision something something something grain pattern in there that nothing else will do it would make sense to be able to throw film grain in post as part of a codec standard, but watch VLC gently caress it up or something. also it would be uniform across the entire movie, and sometimes you want to tweak it per shot. also sometimes you want the grain to appear in the highlights and shadows, so you have to do some trickery either pulling back your max highlight, or making your film grain transfer actually darken the image (change opacity) There's a lot of little details that still need to be preserved, but yeah it does make your encode like 3x bigger

also there would be a big group of spergy people who would want it off all the time and the DoPs wouldn't like that they gave an option to remove "film grain" in mass effect and apparently they took it out because so many people played with it off, and the directors artistic vision was being ruined.

but anyway when restoring a film you need to restore it to its original state, it ruins the artistic integrity of the film to touch it up and make it "better" than it was which is why crap like airbrushing the grain out of Patton is such a travesty

it has nothing to do with film grain looking "better" or even artistic vision, it's just about authenticity. real art restorers try to preserve the integrity of the original and so should film
