"B" roll is when you run different video over a sustained audio track from another cut. How do I put new video clips over a sustained audio track from a different video clip? Maybe another way of asking this is how do I extract the audio from one clip so that I can use it with different video clips? Do I set up different tracks for each video clip or do I put them all on the same track with the sustained audio I want to keep?
Sorry if this isn't clear. I don't know how else to ask this.
