Part 2 - Tracking the Camera Motion

This tutorial introduces how to successfully track our piece of footage in order to get the camera movement data, using the software program PFTrack. Due to having two groups of motion that we need to track (one being the camera, the second being the lizard’s head), we need to track each part separately, and for that reason we will go about it by using a mask to block the movement of the lizard’s head.
