Thanks for the response OSUblake. This is a difficult one to describe. I want the sweeping animations (and an opacity "#flash") to cover up the video looping glitch, reliably. When it's synced up, it looks great, but I've no idea how to keep them from getting out of sync, which is why I was thinking 'Timeline'.
('#sweep_fast' animation runs twice for every ONE of the other animations and video loop, which is 15 seconds)
