Hmm, I don't think I misunderstood? I get that they're using MuZero to decide the bitrate for equivalent perceptive quality as a function of the content. Sure, once they decide on that using MuZero it's a valid compression and the end-user doesn't have to do something extra... But it's super expensive to run that on the server's end, no? So it ends up being a bit like an asymmetric (in terms of client/server) compute/compression tradeoff, right? And you need to run this for each file you want to compress, hence it's "online".
