Q: FCP X will not make multicam clip

I have a 2 camera Iso record that I'm trying to do a multicam with. The footage is 2 ProRes LT files with identical audio that I imported Leaving Files in Place. The first odd thing is that it took a long time for a render to finish that turned out to be FCP generating audio waveforms of each file. When the Background Tasks window showed the files were at 100% complete, the indicators showed FCP was still busy. Quitting and restarting FCP cleared the indicators and gave me two playable files. But now when I want to create a multi clip, the window shows Synchronizing Multicam-Synchronizing Angles, but never makes any progress past about 1/4 done.The footage was recorded on a Blackmagic Hyperdeck that has 16 audio tracks, but I only used 1 and set import to Separate Mono and Group Stereo and to Remove Silent Channels. The footage is on a 7200 RPM 1 TB WD Black scratch drive installed in one of the HD bays of my Mac Pro. That drive is about 80% full . Preferences have been trashed.

    How long are these clips?

    Did you set some values for "Camera Angle"?

     

    You could set a marker on each clip - it does not need to be frame accurate, just give an approximate sync - and select "First Marker on the Angle" for Angle Synchronization. Keep the box "Use audio for synchronization" checked as well:

    Thank you I'm synced up now.

     

    I've come to realize it just takes a long time to render those audio waveforms. These clips are 2 hours long so that's four hours of stuff FCP have to work on. This was just a test, not a paying job. The real test comes when I've got 3 3 hour clips to sync.
