to stand out only within the boundary of the search region, not within the entire frame. Confining the search to a
small region saves search time and makes the search process easier, but runs the risk of the feature leaving the search
region entirely between frames.
The attach point designates the place of attachment for the target footage—the layer, image, or effect

that you want to synchronize with the motion footage.
You set up, initiate, and apply motion tracking with the Tracker Controls panel. The Tracker Controls panel lets you
track a feature's scale, turn feature magnification on or off, choose different actions based on the tracking accuracy,
and show or hide tracked motion paths. You can set up a tracker and its track type before defining a motion target.
To open the Tracker Controls panel, choose Window > Tracker Controls.
