@EmsDad , I realize your post is from last summer, but Dennard now has a stand alone video about how to shoot your own prescreen. We have watched and it is excellent. It is available to purchase for under $29 and well worth the money. These kids know how to and her video shows how to do it for free and get a great video. Not necessary to spend a bunch of money on production. The video does not say that live accompanists are required, but shows how to shoot with both live and recorded
