When making a music video, the music track is the first item I put on the timeline into the "Soundtrack" track. Then, I add video clips, attempting to tightly sync images to the music.
Problem is, as I edit the video track, the "Soundtrack" audio track keeps getting fragmented. As a remedy, I frequently need to overlay the abused audio track with a fresh copy. My question is: Is there a way to lock the audio track so it will not get fragmented while the video track receives major changes and minor tweaks?
In other words, is there a way to choose to have an audio track either locked to the acompanying video clip (as with speech) or locked to a reference in the time line, as with background music) -- the latter being so the music will not get ruined while video clips are tweaked? I hope I am making myself clear.
History: I am attempting to migrate from iMovie. I did mange to make a descent first-try music video with PE (http://www.youtube.com/watch?v=e8G5DMESH_o); but due the the frequent fragmentation of the audio track, it was a frustrating and lengthy process. (Pan and zoom's altering the clip-length also contributed to the pain -- possibly, operator error.) The editing process got a little easier after PE [evidently] corrupted the project, such that the audio track became un-editable. At that point, the audio track quit being fragmented (except for one locked-in "orphan"), and the video editing went quicker.
