Hi Jeff,
Yes, I nested the track which contained the multiclips. I had 8 videos all together that I edited, 5 of the videos exported without incident, but these three would crash every time and not allow me to export.
I ended up calling FCP Professional support and the guy suspected that FCP had somehow become corrupted. He suggested trying to export on another computer I have with FCP and also reinstall FCP on the computer I was having issues with. I did this and the export, yet again, crashed. I decided to re-digitize all my footage and then completely rebuild the edit from scratch. This time I did not encounter any of the weird issues I did the first time, so I was hopeful when the export began. Unfortunately, it crashed again.
At this point, I am completely stumped. Does anyone out there have any ideas about what could be going on here?
Thanks!
