What is the preferred method for masking out areas to be tracked with the planar tracker?
I have a moving gimbal shot in a house, with an actress next to a window. A loose diffuse gel can be seen fluttering outside the window and catching reflections, making it pretty noticeable. I would like to use the planar tracker to track the window frame, then apply the track to a clean plate of just the inside of the window where the gel isn't blowing to "paste" over the shot.
The issue is that there are trees and bushes blowing in the window filling most of the window frame, preventing the planar tracker from getting a good lock on the window frame itself, and causing the track to slip and slide all over.
My question is, is there a way to obscure certain areas of the frame from being tracked? (in this case, a simple rectangular poly inside the window frame would do the trick, but I don't know how to use it to mask or prevent tracking from within that area.
