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.
