Modifying Tracking Data With Expressions in Nuke

In this video I build on the Nuke stabilize and match move nodes that I built in my previous video: https://www.youtube.com/watch?v=OfR-iPK1sOo We're going to take the expression that we used in that video and add the ability to scaled the results, and animate the effect. This allows us to create a fake 3D tracking effect and ramp in or out of the the movement.
