I recently imported native 720p canon t2i footgae via a memory card reader to my late 2011 MBP (2.2 i7, 8GB RAM) and the playback is choppy. The stagnant nature shots are smooth, but when riders come on screen it starts to 'stutter' and it needs to be paused for a little bit before resuming in order to temporarily aleviate the problem.
What gives?
