Once in place, we can switch back to the Shape menu :
and continue our tracking.
The tracking data is calculated from the offset shape and applied to the original.
When the Offset button is enabled, the offset shape is used to generate the
track. You can set the offset shape to any suitable position in the frame. If a
better position becomes apparent, you can re-position it again.
For an offset shape track calculation to work properly, both the
original and the offset shape need to share the same type of motion.
Predictive Tracking
Normally, if the tracking calculation fails at some point in a shot, tracking
stops. In some cases, it is apparent that the track path could simply carry on
as before, the path being extrapolated based on its previous history.
