Ok, so I have an idea of what I want to make as a video but I am interested in knowing if it is possible. I'm not looking for instructions on how to do it, if I can be reassured that it is something that can be done then I will spend more time learning how to do it on my own. I want to film myself playing several of the different instrument apps on the iPhone. They are simple apps so I would also need to use layers to properly create the song (ie I would need to film the drum part in about 5 layers - 5 different 'beats' to make it sound decent). What I want to have the movie end up looking like is as follows: Picture the screen in 16 (or any number, I'm just guessing at 16) different squares (4 across x 4 down). As each layer is introduced in the song I want one of those squares to play (in a loop) one layer. When a new layer comes in I want to use another one of those 16 squares to play it back. I would need to loop each square because it would probably only be a 4 or 8 count for each clip. Hopefully I was able to explain that, but basically I need to know if I can play approx 16 different video clips on a loop using iMovie.
