Jeremy,
My footage is 1080 30p ProRes, and I’m in a 720p project so I can still pan and zoom etc. So there’s no 720p project setting at 29.97, which is what your last advice recommends setting FCP’s playback settings to, so I can’t do that. Working at 59.94 seems to work, but I am noticing the sync drift now just playing back the timeline, not in ETT, but it’s the same lag.
This is frustrating because it’s so close to working, just no cigar. BTW I don’t have a FireWire hooked up to this computer per Oliver’s suggestion, and the video playback and audio settings are where they should be.
Have a wonderful day.
