yesterday rich played this movie at a cms pioneer training day. it's a foo fighters track - can't say i'm that familiar with their music. anyway people liked it so much he has put it up on youtube. he made the whole thing in keynote - i had a look and on one slide there were around 79 transitions! and to get it to sync with the song he simply did the transitions manually. he then used snapz pro to record the presentation as a movie. i hadn't come across this before but it looks like a very powerful little tool to record anything on screen or on an area of your screen. genius!
