I still see video artifacts and not ball movement. Watching the cue ball dots, you can see the expected rolling as the last dot rolls out of view at the top of ball. Coincident to this, a lone dot appears just above the cushion in what appears to be motion consistent with a rolling ball. There is a jump in focus at this stage that might be construed as ball motion but the 6 ball at the top enlarges in concert; therefore still no contact.
In the very next frame, the rising dot is clearly moving vertically - consistent with rail induced spin and it is only in this frame that that actual movement by the three ball is captured. Split at best, and un-callable by eye on the fly.
Nitpicking this because it's not just video that can synthesize ball motion. In practicing feathering, I have on many occasions detected movement when no contact had occurred. Shadows, reflections, IDK for sure but it happens.
