In the QuickTime Settings section you can set the frame rate, compression and data rate.
What is Millions+?
In the QuickTime Settings you can set the color depth for your movie. If you choose Millions+, the movie is saved with an alpha channel that defines the non-object areas. To make this feature work you must check the Ignore stage color (generate alpha channel) checkbox in the the QuickTime Export Settings dialog panel.
