I was told that it was best to record audio separately for every talent so that it would be easier during audio post if I want to increase the gain for one of the tracks etc.
So if I only have a boom mic and I have a single shot of person A's reaction (no dialogue but some whispering) to person B's line, which will be fed to person A, how should I go about recording person A's reaction if I do not want person A's reaction sounds and person B's dialogue to overlap.
What I originally did was to focus on person A while person B feeds him his lines. But it resulted in person B's dialogue to be off axis and overlapped with person A's reaction sounds. And if I request person B to not feed the lines, how can I go about cueing person A on when to react? Thanks!
