Another example of multiple track use.
You have a long clip of a talking head. Nothing to watch but has a good story to tell. So you run it on one track to set the subject and for the audio. Now you have several short clips covering the subject of the talking head’s discussion. You strategically place these on secondary tracks toadd to the interestofthe comments. This lets you come back to the talking head at any time and it still be in sync with the audio since it was playing thewhole time.
