Chapter 7 Tracking and Stabilization 207

The eatatjoes image drifts away from the background image. The Stabilize node is

trying to stabilize the image—the opposite of what you want. To match the eatatjoes

image to the movement of the building clip, invert the transform by setting the

shrewdly named invertTransform button to “match.”

6 In the Stabilize Parameters tab, set inverseTransform to “match.”

The eatatjoes sign moves with the background plate.

As shown, you can use the Stabilize node for stabilization and matchmoving. Others

lurking around the office prefer to use the MatchMove node, described in the next

section. There is one gotcha with using Stabilize for matchmoving: You must turn off

the transform and connect the Stabilize node to the background (tracked clip) in order

to re-track.

Note: When destabilizing, the inverseTransform toggle can also be used to reapply the

same jitter that was removed. You may have a slight jitter due to gate weave. Stabilize

the shot, apply all of your elements to the stabilized plate, then copy and paste the

original Stabilize node to the end of the tree. Then, set inverseTransform to match, and

you arrive with the same natural-feeling jittery movement.
