Understanding how to use the Tracker tool and apply the tracking data to elements in a composition, and determining to which parameters you want to apply the tracking data are key factors for producing basic to complex effects. The more experience you gain from using the Tracker tool and applying tracker data to elements, the more you see all the effects that trackers can produce. If your composition is jittery, use the stabilizing feature within the Tracker tool or the Panner tool to remove, for example, unwanted camera jitter.
Tracking and stabilizing are often processes of trial and error. You should track or stabilize with default settings, and if the tracker box strays, fine-tune the analysis.
Much of the tracking and stabilizing work you do will be done using the Reaction supertool—see Reaction Compositing and Effects, and the 2D Transform Tool—see 2D Transform Tool.
