I am importing P2 footage into FCP X 10.0.9 and am running into an issue where footage comes in with only a few seconds of audio and jumpy video on playback. (The latter looks like playback varies between a modest slo-mo and modest speed ramp.)
I have read elsewhere that this has something to do with advanced pull-down and that the proper import setting was to UNcheck "Remove Advanced Pulldown" on import.
However, this footage appears to be shot in straight-up 29.97 progressive, so that does not seem to apply.
(The pulldown option is greyed out in the Import window.)
The raw MXF files play back fine in Premiere Pro CS6, so footage corruption does not seem to be an issue either.
