Positioning the Reference Box

When you position the reference box, the tracker box automatically moves to the same location so that when you start analyzing, both boxes are positioned over the reference point.

To position the reference box:

1. Go to the frame where you want to position the reference box.
2. If the tracker you want to position does not appear on the image, click the appropriate Tracker in the File Browser, and enable Active.
   

   (a) Active column  (b) Selected Tracker Analyzer set to Active  

   NoteEach tracker is automatically assigned a different color. However, you can customize the color at any time—see Changing the Color of the Tracker.
3. Position the cursor to the center of the reference box until it changes from a cross to a multi-arrow shape.
   
4. Click and hold the reference box and drag it over the pattern you want to track (in the example below, the rider's head). The reference box is magnified to make it easier to select a position. By default, the tracker box stays with the reference box.
