Went to Europe, shot an hour of HD video on the iPhone 4. Looks good on the phone, smooth video playback.
Got home, imported the video into iMovie '11, arranged the clips sequentially, left all settings at default, added a little background music, nothing fancy.
Hit the Export > 720p button, waited 3 hours, got my completed video, runs 35 minutes.
Upon playback on that MacBook or my iPad or my Apple TV, the video is jerky. Whenever the camera pans and there's motion on the screen, it stutters or hesitates for a quarter-second approximately every 3 seconds.
When the camera's not moving, can't notice it. But if you're watching the glass elevator ascend the Eiffel Tower, you can see the stuttering. If you're watching a car drive next to the tour bus, you can see it 'jump' forwards a few feet every few seconds instead of moving smoothly.
When I use iMovie on the iPhone I never see these issues. I used the MacBook to do it because there are too many clips to edit on the iPhone, thinking that if anything the playback quality would be better on the high horsepower notebook, not worse.
Can anyone tell me what settings I should be using to eliminate this issue? iMovie has a bunch of options, including one called "stabilization" but I take that to mean that if I have a shaky hand it'll steady the image. That's not my issue. I'm rock-steady when I shoot video. The issue is somewhere in the iMovie '11 conversion process.
TIA if you can point me in the right direction.
