I've shot some footage with a gh2 at 720p60 that I've logged and transferred via FCP. When I play it back, I keep getting an intermittent dropped frames message and the playback is jittery. When I simply open up the quicktime files with quicktime, they playback fine. I double checked the sequence settings and they match the clip settings. I don't have any problems with 1080p footage and fcp. What's going on here!?
