I'm really confused. I just watched the video again, and I cannot really see the effect that you're talking about. In fact, I struggle to see any difference fr

  I think it would be easier to see if they had a comparison between a high bit rate traditionally compressed video and their neural net compressed video. To me the facial shapes and movement seem just a little bit wrong like you’re looking at a 3D animation of a person instead of a video.

    They do this using GANs so I don’t think it is compressed in any way. Instead, the points on the face are sent across the net and the face is actually generated. I’m sure it can get better with time. There is a site thispersondoesnotexist.com that uses the same tech but looks real.

The bits that are missing are reconstructed using a bias built in the compression algorithm. Deep learning based algorithms simply have a more realistic bias, so the artifacts that introduced to replace the missing bits are less noticeable.

  I want to see if people notice this effect when they don't know it's artificially generated. I have a feeling that the uncanniness is at least part because you know it's fake.
