I’ve done quite a bit of XDCAM and this is what I do.
do the xdcam xfer, while in xfer you can find out what flavor
of xdcam it is, ie 1080P 30 VBR etc…. to load the appropriate easy setup.
then edit in an xdcam timeline in final cut pro..BUT change
the render settings of the xdcam sequence to ProRes, that way you
don’t have to render the whole timeline.
This has worked well for me for quite some time.
Save often. if you happen to have multiple timelines open you will likely get the spinning beach ball and a crash. This is a characteristic of fcp7 with xdcam and having multiple sequences open.
