After Effects CC 2015 - Face Tracking Feature Tutorial

In this tutorial, Evan Abrams will review the new face tracking feature in After Effects CC 2015, that allows you to track faces with exceptional accuracy.

The Expression used in this thing later on to rotate things using points and trig is:

A=thisComp.layer(“RAW INTRO_28_07_2015_461.MOV 2″).effect(“Face Track Points”)(“Mouth Right”);
B=thisComp.layer(“RAW INTRO_28_07_2015_461.MOV 2″).effect(“Face Track Points”)(“Mouth Left”);

// Find the length of side a
SideA = sub(A, B)[1];

// Find the length of side b
SideB = sub(A, B)[0];

//Find the Angle between them
radiansToDegrees(Math.atan2(SideA, SideB))+180;
