I seem to have encountered a bug: I sent an offline edit sequence as XML from FCP7 to RCX-P 14, all worked well. I then exported "timeline separate clips" from RCX in online quality (QT ProRes4444) with 50 frame handles in the export settings and "generate FCP XML" turned on. However, when I import the XML from RCX back into FCP, the clips on the timeline have been slipped by 50 frames. That is, if on my timeline I had a clip where the starting timecode of the clip was 10:45:23:17, it has now become 10:45:25:17. The clips are otherwise placed correctly in the sequence and their durations are what they should be. But for some reason they've all slipped 50 frames.
As this was just a short test sequence, I can fix all the slips by hand, but I've got a longer project coming up soon that needs handles when going from RCX-P to online, so if there's a way to fix this it would be appreciated.
