Using the 720s

A Quicktime VR is a panoramic image in which you can pan and zoom. A 720 degree Quicktime VR is like you are in a big sphere; you can rotate 360 degrees vertically and horizontally.
First, click and drag with your mouse to pan and tilt within the Quicktime VR. Press the SHIFT button to zoom in, and the CONTROL button to zoom out.
That's all there is to it!
