What you will see in a second is four red buttons. The two on the left are the old camera (Sony HandyCam), the on in the middle is M@ (DVC30), and the one on the right is JB (DVC60).
All three cameras are zoomed in all the way, however, the old cam has a different zoom than the new cams, so, the right two and the bottom left are at 300%, and the top left is at 225% (to show size comparison). It looks like this:

Anywho, it is a 1 second clip just to show you motion, so you will want to loop it... just tell QuickTime to loop it (Apple L on Mac, don't ask me how on Windows)
