The Astin shot is a weird one. The finger snaps are certainly at the correct speed, but yes, the footage before does indeed run in slow-mo. I'm assuming it was done to extend the footage, but that's how it was originally broadcast.

As the person who created the video, I think one has to take it in the
manner it was intended – something done as a novelty in the spirit of
fun. It's not intended to be a replacement and you can read my thoughts
behind it and how it was put together here:
