4 Corner Perspective Grid Tracking

You can track the four corners of an Action Perspective Grid in the Stabilizer. Since the Perspective Grid acts like an axis in Action, any tracking data can be applied to other Action objects.

To perform 4 corner Perspective Grid tracking:

1. From the Action Perspective Grid menu's Tracking tab, select the media to be tracked from the Use Media field (to stabilize the Back media, select 0).
2. Set your perspective grid corners.
3. Select 4 Corners from the Tracking Mode box.
4. Click the Enter Tracker button.

   The media is automatically loaded into the Stabilizer and the Stabilizer menu appears.

5. In the Stabilizer menu, enable Context to use the Action scene as the reference.
6. Optional: Refine the position the trackers over the corners that you want to track, and click Analyze to generate the tracking data.
   Note: You can fine-tune the tracking data if necessary. See Tracking Difficult Shots and Correcting Errors.
7. Once you are satisfied with the tracking, click Return.

   The Perspective Grid menu in Action reappears. The tracking data is applied to the Perspective Grid media.
