Bear in mind how compression works. As I recall, it transmits one full picture frame only every (say) 20 frames. In between it changes only the parts that have moved and uses a "guess" algorithm to predict where that moving object should be in the subsequent frames.
So what you are seeing could be normal compression artifacts. This is why the tribunals are reputedly being recorded on film.
I've seen news broadcasts (in the distant past) where the news reader made a sudden move and left his face behind for one frame!

I watched 0.25 speed and you can see black spaces appearing out of nowhere between teeth.
Also edges of 4head changing a little bit too. But I don´t know if it is because of low quality video. (even when 1080p)
