Thanks for the inputs, guys.

That's a great tute for manually adjusting a tracking window, but I suspect Rhys is trying to turn it on/off completely. In his example, while the door is closed, you don't want that power window hanging around making a portion of the frame brighter.

There are probably a thousand ways to do this. I've settled on keyframing the window's opacity. That means opening up the keyframe editor, finding the right attribute (e.g. Corrector 2 > Circ Win ), and dropping static or dynamic keyframes at the points you want to turn or fade on/off your power window. With the appropriate keyframe selected, go back to the Window palette (middle control panel) , select the appropriate power window and change its opacity to 0% or 100% as required.

You might do this in conjunction with manually 'rotoscoping' the window, or more appropriately, changing it's shape with the tracker controls in frame mode, as Duke suggests, which would allow for the edge of the door covering the face for a few frames.
