Hey my man, NAW this is all Final Cut Pro..I've opened after effects like twice and i'm like EH? So i'm kinda just sticking to Final CUT. It's all mostly layering and under MODIFY/COMPOSITE mode...BOOM BAM, yummy transparencies...check it out.
Thats some darn good video scrubbing if that was for a live show. All in all very good. Did you do that in After Effects Mr. Multiple ? That stuff is the food I like.
