Motion Tracking different objects in one pan shot?
 

Hi,

I'm trying to motion track a handheld shot that pans from the interior of a car door up and out of the window to a blank sky.

The only problem is, once the camera tilts up beyond the interior of the car door, there is momentarily nothing for the motion trackers to grab onto. A second tracking anchor appears later in the shot - but only after a considerable delay.

My question is this:

- Is there a way to use a tracking point for the beginning of a shot, use no tracking points for the middle of a shot, and use a 2nd, new tracking tracking point for the end of a shot?

I'm using AE CS3.

Many thanks!

Dave

This should help you out... I think the method is called rotoscoping...
