During his interview, as you= might assume, there=92s quite of bit of head shaking. The nose goes all ov= er the place. There=92s motion blurring that occurs on the clip because of = the motion, and that seems to shake the white spec tracker loose. It drifts= around slightly.

But here= =92s the deal. After applying all the motion and rotation keys to the patch= .png file, the patch locates itself (according to the keyframes) several in= ches away on his cheek.

My quest= ion is:=A0 what is the trick to take a set of motion/rotation keys attached= to the patch.png file, and slide=85

=85uhhh=85I got it! Change the Anchor Point! Doh!=

OK. So now that=92s solved, have I hit Ae=92s wall, in that its moti= on tracker is only so good in high motion areas?=A0 Any other options to pi= n that tracker down tighter?
