mocha AE is a stand alone planar tracking sfw that ships= with After Effects CS4, CS5 & CS5.5.
mocha is excellent for face t= racking and should solve the majority of tracking woes. Simply track in moc= ha AE than paste the keyframes back to AE. Also - mochaImport is an excelle= nt script to assist the workflow.

I= ’ve got a shot—head and shoulders interview on green screen (72= 0p 23.98)—where I failed to notice the little white speck at the edge= of a nostril.

My question is:  wh= at is the trick to take a set of motion/rotation keys attached to the patch= .png file, and slide…

 

…uhhh…I got it! Change the Anchor Point! Doh!

<= p class=3DMsoNormal style=3D'mso-margin-top-alt:auto;mso-margin-bottom-alt:= auto'> 

OK. So now that’s solved, have I hi= t Ae’s wall, in that its motion tracker is only so good in high motio= n areas?  Any other options to pin that tracker down tighter?
