You
can track the movement of a feature in the back clip and apply the
tracking data to the selected axis in Action. The axis follows
the movement of the feature in the back clip. You can also track
the rotation or change in size of the feature. See
One-Point and Two-Point Tracking.
TipTo help you view
your tracking result without any objects blocking the view, enable
the Context button in the Stabilizer menu. While similar to a result
view, the context view allows you to see all of the Action scene,
except for the selected node (and any children of the selected node).
