Suppose I have one 3 minutes clip for angle 1 and two 1 minute clips for angle 2 and "Use audio for synchronization" doesn't work.
I can use sync by "First Marker on the Angle" plus using audio for sync.
However I guess I should put one marker on the long clip and on the first short clip only so that FCPX will not be confused.
In that case the second short clip is left to be synced by audio only and if that fails I can only try to sync it manually.
Is that so?
