I do not know if this is a bug -- I think it is really in the video. If
you put your cursor randomly in the video anywhere around 02:10:00 to
02:11:xx where it is easy to see the swimmer, and then use frame reverse or
forward, you can see the frame move easily.

So I can confirm what you see in other parts of the video though so I will
have to ask GG for an explanation.
