sequence, if the pattern you want to use as a reference is subject to a lot of rotation or scaling. In most cases,
you will position the reference box over the reference point in the first frame of the sequence.
Selecting a Tracker
You can use any of the following methods to select a tracker:
■ Select any tracker Select Tool, from the Stabilizer Tools menu and click the tracker box, the tracking path,
or the reference box of the tracker in the viewer.
■ Select a tracker by clicking its corresponding button (Tracker1, Tracker2, and so on).
■ Select a tracker by pressing the corresponding number key on your keyboard. You must use the number
keys on the alphanumeric keyboard, not the numeric keypad.
■ Select any tracker by pressing the up and down arrow keys on your keyboard.
■ Select any tracker by selecting its channel in the Channel Editor.
When you select a reference box, a tracker box, or a keyframe in the image window, the sequence
automatically updates to the frame where the keyframe was set.
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, select the appropriate Tracker, from the
Tracker box and enable Active.

colour at any time.
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.
