Silly question? Most probably.
I recorded a video of a rock band and an audio file with a Zoom recorder (.wav) which covers the same period. The idea is to have 2 audio tracks which I can activate freely in order to find the best sound-video combination.
The video is in FCP and I have imported the additional sound track (via Sound Effects). Problem: this additional sound track remains mute. “V” for deactivating the original sound (after separating video and audio) does not help.
Where did I fail?
