Hello to all you knowledgeable people. I'm a real novice, so I need to ask the following question. I run the latest version of iMovie. In my work I need to take numerous video clips of which I load into iMovie and create a final DVD. At times there are faces of people in the video footage that I can't just edit/delete, so I am wondering if there is a way to cover these faces from within iMovie or is there an app or additional program that I can get that will help me cover the faces or other things in the movie being created.
