Thanks, glad you like! I'd say "technique" is maybe an exaggeration, but what I did was waltz in with a tripod (that has pads on the feet, so that vibrations from the floor don't jiggle the featherweight Canon S95 that is my camera) and lash to it gorilla-pod-style my Sony PCM D50. This runs constantly, and then I gauge, song to song, whether to start the camera or wait for the next tune.
That's why alot of the time, I need to put together these "intros" that rely on freeze frames until we get to the start of the video recording.
I also (very self-consciously) decided to exploit the capabilities of iMovie to import stills from iPhoto that have been doctored in Photoshop, so that's why there's all this "find edges" and "difference clouds" and "extrude" effects... just to pull out all the stops. See if anyone salutes.
What? No 'saluting' emoticon????
