I hate to say it, because I use Avid… but if this is for high school students, the easiest, quickest, and usually pretty good looking it iMovie. iMovie comes standard on any Mac, so if you already have one… or you could buy a cheap Mac and you’re all set. There is even a check box for the Ken Burns effect. You just dump in the pictures, put the music in, and tell it to arrange pictures to length of music and you’re done. iMovie is how I started. I’ve never touched Final Cut though.
