I have a 3 camera 3 person interview and each subjects audio is on their respective camera. I am using a multicam session to edit. I set the session up so I'm listening to ch 1 on all 3 cameras. I need to match frame back to the original footage because there is too much crosstalk from the other 2 cameras, plus, since the takes are long there is some drift in time aggravating the situation. Does anyone know how to match frame back to the original footage so I can replace the audio?
