How the Tracker Works
 
 
 

The Tracker first tracks motion of the reference feature(s), then applies or inverts that motion, depending on if you are tracking or stabilizing.

Once you have set up your trackers, the analysis can begin. This is how the Tracker analyzes and remembers the motion of the reference feature:

In all tracking except for stabilizing, the Tracker applies the shift values without modification.

With stabilizing, the Stabilizer operator inverts the shift values, resulting in a negation (and therefore elimination) of the motion—see Stabilizing.
