adjust clip length without affecting audio
I'm working on my first iMovie project. It's just a series of photos set to an audio track. The problem I'm having is that when I adjust the length of a photo it simultaneously adjusts the length of the audio track. I want to be able to adjust the length of the photos so that they coincide with various positions in the audio track so I need the audio to track to remain stable.
Help?
