Capture audio from movie being played back
So my company has asked me to make one of the videos of 30 people all singing together. Those that work in my field have used either Logic Pro X or Adobe software to complete this goal. For fun I decided to try it in Isadora. I am using 2.6.1 at the moment.
What I have been successful in is capturing the video part by using "capture stage to movie" actor. And I have been having fun with that. But what I can't figure out is how to make Isadora capture the audio from these movies. To be fair I have never used "Live Capture" before. But I did figure out how to capture me and the things I have said. But what I have not been able to do is figure out how to get the capture to take the audio from the movie and not from my mic.
the questions are:
is there a way to make this happen? and I have searched for 3 days on the internet and either I don't know the right word to search with.
Is this pointless in Isadora and should I just go back to Adobe?
