Xto7 for Final Cut Pro ($49.99), previously named Project Xto7, translates the FCP X Project XML (fcpxml) and converts it for import into Final Cut Pro 7. You can also go directly to Color, Soundtrack Pro, and to other Final Cut Pro 7 XML workflow programs, as well as to Adobe Premiere Pro (and thus to After Effects via dynamic link).
The multicamera said multiclip might not be around in this version of Final Cut. It turned out to be an issue with the way Apple handled the audio data. I had to reassemble the multiclips in FCPX, record and return them to Final Cut. I then bring them into PluralEyes and synced up most of the Multiclips, but wanted to work through the sync issue for the last one. Extra audio cues left on the multiclips in Final Cut made it harder to sync.
By creating multiclips first we could see how much of the first version of the story we could move into the new multicameras. Then I exported the file to IEX Pro for editing. I could preview the multicamera clips in ProGrade to make sure they were conforming. If any multiclips were out of sync, I would go back into find the cut I'd made and apply all the sync fixes. 7211a4ac4a
