Use a matte to delimit the tracking results. White areas of the matte are considered for
calculating the solution, and black areas are ignored.

for calculating the solution, and white areas are ignored.

GMask Option box Select whether to track inside or outside of an attached GMask shape.
While in an Analyzer view, you can add a GMask node and instantly draw the constraining mask. If added
while in Analyzer view, the GMask and Axis nodes are automatically connected to the image as part of the
Analyzer tree. If you want to use an existing GMask node, make sure that you parent the Surface (mono
analyzer) or Stereo Object (stereo analyzer) to the Axis of the GMask in the schematic.
The GMask Option box is unavailable on Smoke, unless a setup is loaded in Action with an existing Action
Gmask node.
Intersect Constraints field Displays that the intersection of the two constraints above are used as the
tracking region. Non-editable.
