made two quick vids doing a test of the gopro 3 black edition camera.
Both clips are run at 100%, then 50%, then 25%.
Because 720p records in higher frames per second, at 25% its a LOT smoother.
Excuse the grainyness/blotchyness of the vids, still mucking around with export settings
First is in 720p, 120fps.
second is in 1080p, 60fps.
