A Tracker node branched from the node tree
The Tracker can also work as a replacement for a Merge tool in match-moving setups. Below,
the Tracker tracks the image connected to the orange background input and applies the
tracking data to the image connected to the foreground input. The same foreground-over-
background merge capabilities are available in the Tracker node.

Tracker Onscreen Controls
Each pattern in the Tracker has its own set of onscreen controls used to select the pixels in the
image to be tracked. These controls are visible in the viewers whenever you select a tracker in
the node tree.
Pattern Rectangle
In the viewer, the tracker displays a solid-line red rectangle called the pattern rectangle. Every
pixel within the rectangle makes up the pattern used for tracking. You can resize the pattern if
necessary by dragging on the rectangle’s borders.
