Camera operation from FCP and another earlier edit program I used on OS 9 - Cinestream - was also flaky. I think I rebooted when it happened. -- To de-mung my e-mail address:- fsnospam$elliott$$ PGP Fingerprint: 1A96 3CF7 637F 896B C810 E199 7E5C A9E4 8E59 E248

If the tape was really bad, I'd capture in two clips to "different" reels to eliminate the break. Timecode breaks were too much hassle to work around. You could never offline your assets because you could never recapture in batch. -- To de-mung my e-mail address:- fsnospam$elliott$$ PGP Fingerprint: 1A96 3CF7 637F 896B C810 E199 7E5C A9E4 8E59 E248

For some reason when I download to the slow disk it doesn't actually 'drop' the frame, but appears to 'repeat' it, so when playing back the action freezes for two or three frames, and there's no discontinuity in the time code. Doesn't answer my original question, though, so I'll just start using the fast disk. Thanks for the help. MST

Camera operation from FCP and > another earlier edit program I used on OS 9 - Cinestream - was also > flaky. I think I rebooted when it happened. I nailed it! It's iDVD causing the problems. Yet another ridiculous, inconsequential bug in this festering latrine of a program. What the hell does iDVD have to do with my camcorder? This is on a par with the bug where it forces DVDs into widescreen if the audio is in a format it doesn't care for. If there is a hell I know how the inhabitants will be doing their DVD production.
