Hello, I am attempting to get an effect in imovie like the one seen in this video: http://www.youtube.com/watch?v=U-lt3vVA-4I&feature=channel_page or, similarly, this one http://www.youtube.com/watch?v=mHwV2JuwZls Me and a friend are interested in combining the audio from multiple clips (one clip for each instrument) and then editing the clips of us playing together and putting the combined audio over that video but we aren't quite sure on how to get started. We figured there had to be some way of using imovie or imovie + garageband to easily get this effect. Any ideas? Edit: Sorry for the typo in the title. "Combining audio FROM many clips into a single movie"
