Some comments have touched on some possible issues such as the swapping of key-frames of someone else's face and possible funky effects by introducing other faces and or objects into the camera image.

But I haven't seen anybody touch on the compute cost required to implement this. As I'm not in the machine learning field I don't have a good idea what the compute cost is for something like this. Can anybody chime in on that?

If this "codec" were to require a somewhat beefy gpu I don't see the benefits at all. Current H264 is usually done by hardware decode and sometimes even encode. In areas where bandwidth is constrained I would imagine a lack of computing resources, thus nullifying the entire premise. That said, in current times it would save a substantial amount of data transmitted. But I'm not sure if we should lock-in our entire videoconferencing system to nvidia just to save some bandwith.
