So I captured some footage the other day into FCP from my XL2 (24p 16:9 encoded in Apple's ProRes Codec) I edited the whole thing, rendered it out. Everything was peachy. Any time I try to export it, the audio stays in sync, but some of the video clips get offset by a 1-3 seconds, occasionally a black frame will be put in before and after cuts. Sometimes when I try to print to tape this doesn't happen, but my XL2 refuses to receive the video and audio. I can see a still image when I'm in the timeline, or even see animation and the eq bars bouncing when I scrub, but when I just play everything goes still. I should alsp add that after exporting everything in my timeline is offset too, but not always. I've tried different editing timebases in different sequences. I can normally get back to a working version of the video if I copy and paste it into a new sequence. Has anyone had this problem? Can anyone help? This is for a school project that is due Thursday, so I would greatly appreciate your help.
