all i want is a video compression algorithm that detects which parts of the image have some kind of high-frequency shit in them, stores that before it encodes the image, and then on the other side it resynthesises a kinda plausible distribution of noise/grain/dithering at the approximately correct magnitude in the roughly correct places
all i want is that. and for youtube and everyone to start using it
(bonus points if you can also resynthesise water ripples)
@jk this is basically the video version of how the opus audio codec handles "noise" (which honestly is pretty cool)
AV1 has film grain simulation: https://norkin.org/pdf/DCC_2018_AV1_film_grain.pdf which is part of the way there. it might help, at least once the encoders get good.
