Tracker connected as a branch to indicate it is
linked to other nodes and not used directly.
Analyze the Image to be Tracked
After constructing the node tree and inserting the Tracker where you want, you can set up the
tracker in the viewer. You identify one or more features in the image that you wish to track
(referred to as patterns) by adding trackers (there’s one by default) and positioning them using
the onscreen controls in the viewer. After the Tracker node analyzes the clip, the resulting
tracking data is stored within that Tracker node. Keyframes, one per frame, indicate the Tracked
Center X and Y data that has been saved, while a motion path shows the path of tracked data in
the viewer.
A motion path that indicates the tracked motion, and tic
marks that indicate tracking data keyframes.
Apply the Tracking Data
The resulting tracking data stored within the Tracker node is used to stabilize, match move,
corner pin, or remove perspective in one of two ways.
Method 1: Use the Tracker node to match move and merge
You can connect a foreground image to the Tracker node and apply the motion from the
analyzed background image.
