I just upgraded to FCPX 10.1 and tried to use Plural Eyes 3 to synchronize a shoot I just worked on (2 dslrs and external audio). I synced the footage in Plural Eyes without issue, and exported a multicam clip into FCPX. The problem is that no matter what I do, when I drag the clip into the timeline, it gets a big red bar and says that it is (missing). When I open the clip in my browser window all the files are there. But the second I drag the clip itself down into the project timeline, nothing shows up and I can't seem to modify the event settings.
Any ideas? I've got 40 minutes of footage and a synced multi cam clip is a lifesaver.
