My friend Eric used an Apple Program - I don't know the name. I did a few edits using Corel VideoStudio Pro X4. I'm not crazy about either program. While I'm happy with the results, it was unnecessarily time consuming. The Apple program wasn't allowing us to insert the clips from the third video camera, and the Corel Program gave me a lot of grief in making the clips take up the full screen.
Thanks for the compliments.
