If I have a piece of video footage with an voice track, how can I go about switching to a different shot, but still having the same audio? Is this what the 'Video Overlay' channel is for? To rephrase the question, If I am giving a tutorial about how to sow shoes, and in the middle of a video event I want to switch to a shot of some other shoes, and still keep the audio track of me explaining how to sow shoes, how do I go about doing that? thanks for any help.
