Well, it's not that important. Probably just 2/3 frames with that and it looks more like a fault from ytv and not you. The scene wasn't in the Funi version, I don't even know why it's there.

It's a frame corruption issue caused by (we think?) either my CPU or my RAM that's making it pull the wrong frames into place on certain keyframes.
It's really frustrating as I thought I'd fixed the problem this week and didn't notice that specific corruption because of how short it was, until it was too late.
Really sorry about that, I'm looking for ways to get around it for now, either by using the group's server or someone else's PC. It won't happen again.
