I am trying to track a face and not getting a good result

It's common to want to track a face for isolated color correction or to do a skin treatment effect or blur or pixelate the face to hide someone's identity.

To get good results please remember that mocha is a planar tracker, so the track shape you draw should approximate a flat surface (a plane).  If you wish to track someone's face, please draw a track shape like this around just the front of their face and not their entire head.

If you draw the shape around the entire head, then as the head turns with perspective, it will lose the track because the entire head is not a flat planar surface.
