You'll be waiting for a long time then, probably. Making codecs is actually a hard problem, the type of thing that AI completely falls over when tasked with.
It works amazingly well with text compression, for example: https://bellard.org/nncp/
AI video could mean that essential elements are preserved (actors?) but other elements are generated locally. Hell, digital doubles for actors could also mean only their movements are transmitted. Essentially just sending the mo-cap data. The future is gonna be weird

You could probably also transmit a low res grayscale version of the video to “map” any local reproduction to. Kinda like how a low resolution image could be reasonably reproduced if an artist knew who the subject was.
