Typically A1 is the only audio track that comes over in a multicam edit unless you check Audio Follows Video from the Multi-Camera windows's flyout menu.
OK, maybe I should clarify...
Only A2 is coming through, NOT A1 -- so that's inconsistent with what you're saying. I have not checked Audio Follows Video, because that's not the bahvior I want. I'd like to be able to choose from any of the video tracks. Is that not possible in Premiere Pro?
Also, do you think it makes a difference that I'm 'multicam editing' from a regular sequence (with multicam enabled) as opposed to an actual multicam sequence?
thanks for the help.
I don't know why you hear A2 instead of A1, but if you want more detailed control over the audio mix, it might be best to copy/paste the original audio clips into the multicam nested sequence.
