I'm having some trouble with the motion tracker. It's often very shaky; often the location of the translation block will swap between locations half a screen a each frame for a few seconds. Also, the translation block is often very far away from the hand and mouse. and it's quite difficult to set the location of the translation block and search area because the picture moves around so much when I do this. (I've been playing with the motion tracker with stabilization.)
How do I add a track with a cross like in the motion tracker samples? I figure that the picture won't bounce around if I track instead of stabilize.
