I've had problems on a DVCPRO HDVp60 footage. The footage when edited will be jerky in some parts and not others and on the same clip. From what I've gathered, its usually either all jerky or not, but this not so in my case.
I've tried recapturing but the problem persists. Any ideas?
Select any of your video clips in the browser and type cmd+9. Post everything in the window that will open.
Match the sequence settings to it. You've not done that. You make it the size you want in the end... but edit in the same format you've shot, or gathered materials with. This is your problem or you're using a format not supported by Final Cut Pro. The frame size is odd, and it's either DVCPROHD or HDV.. right?
