Smooth external view rotation? (Activecamera)

I am creating some little video clips of external views of aircraft to share with some friends who use a different simulator than FS9. An example can be seen at http://tinyurl.com/5klk3 . This is in Quicktime format since the folks I am sharing with are Mac users. I use Activecamera and pan around the aircraft with the middle mouse button held down (gradual transitions in spot view turned off). No matter how smoothly I try to pan with the mouse I get some little jerky stops and starts from the mouse. Is there a way to program in a path for the "camera" to follow so that it is all done in software? Forgive me if this is the incorrect place to post this but I am just starting out to look for information and I thought this would be a good place to start.Point me in the right direction if this is not the right place please?Bob
