I was putting together a music video out of boredom, and getting used to using iMovie 09, but a lot of clips near the end will not stop playing snippets of sound here and there. Sometimes a bunch of the play at the same time over one clip. This happens even when I turn the volume of the song to 0% just to see if the random sounds would play without it over them, and they do. So I deleted the audio from each clip by detaching them and then deleting, but they still played. Then I tried just setting the audio to 0% and even reset ducking on the Song playing over them to 0%. None of this worked. Mind you, this only happens when it is played in fullscreen mode. If I just press space bar and play it as is, it works fine. Can anyone explain what is going on?
