I haven't got a tripod yet, so it would be shaky. I was thinking of a top down view, but that would limit acces to the phone and would require a boom arm, maybe a remote shutter release would solve this problem, but then I would have to choose either to shoot video or stills and some effects work better with pictures.
Another issue is background music, iMovie can use only iTunes, so even if I had a royalty free mp3 it's of no use, dunno how to deal with that yet.
Damn what have I got myself into?
