I suspect that this isn't feasible. Otherwise lossy video codecs wouldn't exist (or would be very niche). Because if you sent a perfect diff you would essentially have lossless compression again. So either your idea will revolutionize video compression or the "diff" would bring you back to the ballpark of lossless codecs.

It is a lossless codec yes, but I has a “base” image for the key frames (which are the most expensive) which can be transmitted as the key points. The question is how much that actually helps the end result vs how much it costs. As I said it would likely kill at lest nearly all the gains, but again - a small improvement in the state of the art for “normal” looking video would be more impressive than three orders of magnitude vs sending instructions to my head puppet.
