Dropped Frames don't matter. It's just playback, most systems will drop frames with HD video. It could be any combination of a number of things, but it doesn't mean anything. Turn off the warning, ignore it. When you Export your final work, all the frames will be there.
Its defenitly not a slow hard drive as im working with the latest and greatest macbook pro. I will turn the warning off and continue with my editing. Thanks a lot BenB, youve been a great help
Um, MacBook Pro? If you're on a FW800 drive, that's barely fast enough for HD editing. And I hope you're not using your internal drive as your Scratch Drive. What is your drive setup?
