I tested with a couple of different projects today & haven’t been successful creating a new trimmed project yet. Exporting XML from FCP 7. If I were to guess, I would say it bails out at the same clip each time. So I would blame the assets. I didn’t know if you’ve heard of users having troulbe with MXF files. One of the tests just completed 1 of 20 clips then crashed. I’m running a quad core Mac Pro with 32 GB Ram, Nvidia Quadro 4000, AJA KONA LHE etc. Don’t know all specs right now.
