no it wasn’t. Although I’ve read shooting with the firestore has similar issues. We shot to cards, and offloaded to a PC formatted drive in the field (not fat 32), and then moved them over to the mac. I used P2 log to view and convert the MXF files for FCP, but I do still have access to the original MXF files. I’ve discovered something else in my quest for a solution. If I stitch back together the clip (broken over two P2 cards) in an HD timeline, the missing “frames” show up. but in a SD timeline they’re gone. tried to trick FCP by exporting the two clips as a QT movie, but in the QT movie file (SD or HD) the frames disappear again. Am I making sense to anyone? Yikes.
