7D video drops frames when played back using on Mac using QuickTime Pro.
Recorded video with 7D in full auto exposure mode in full HD at 1920x1080 and 30 fps. Lens IS may have been active, not sure.
In-camera video playback is smooth, and so is playback on HDTV via the HDMI port. Playback of *.mov file on Mac using QuickTime Pro drops frames - very jittery. What's the problem?
