I have a sequence with two video tracks and one stereo audio track (recorded separtely and synced), and placed it into my "main" sequence for editting. Before enabling multi-cam, the audio levels are noticibly higher, and once setting multi-cam to enable, the volume levels drop about 2-3db. I then have to raise the volume to compensate for that. Is this a bug or something particular about the way multi-cam clips are handled?
This is normal. Multicam by default only uses Audio 1 of the source sequence.
