How do I sync multi cam using a specific audio track
I have two recordings which I wish to sync. One recording is a camera shot and the other is a game recording. One of the game recording audio tracks has my computer microphone captured. I would like to sync the two clips using the specific audio track from my computer microphone and the camera clip which has its builtin microphone as FCPX could easily use this to sync using audio. I have not yet been able to identify how or if I can do this in FCPX.
Thank you in advance!
