Positioning the Reference and Tracker Boxes

When you position the reference box, the tracker box automatically follows. You can leave the boxes together if you place the reference box in the first or last frame of the clip. However, if you start the analysis on a different frame from where you position the reference box, you should position the tracker box in the first frame of the clip on the pattern you want to track. This way, the Stabilizer knows where to look for the pattern to track when you analyse the clip.

To position the reference and tracker boxes:

1. Go to the frame where you want to position the reference and tracker boxes.
2. If the tracker and reference boxes do not appear on the image, click the appropriate Tracker button and enable Active.

   NoteEach tracker is automatically assigned a different colour. However, you can customize the tracker colour at any time. See Changing the Colour of Trackers.
3. Click inside the reference box to select it, and drag it over the pattern you want to track.

   The reference box changes into a magnifying glass. By default, the tracker box follows the reference box.

4. To position the tracker box on a different frame from the reference box, go to that frame and move the tracker box over the pattern to track. To move only the tracker box, click anywhere outside the reference box.
