To remove jitter, or track the movement of a feature in the back clip, you can apply tracking data to an axis using the Stabilizer. You can access the Stabilizer directly from the Axis menu in Action.
(a) Stabilizer button (b) Tracking Data controls
You can import stabilizing data from the Stabilizer to lock the position of the selected axis to a reference point on the front clip in Action. Any movement in the front clip is matched by the axis. See Stabilizing a Clip from Action.
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.
