Chapter 7 Tracking and Stabilization 213
The three extra trackers are activated. Each tracker is located in the relative corner
where it should stay. For example, the upper-left corner of the foreground image is
connected to track4 of the MatchMove. Shake uses Cartesian coordinates, so the
trackers are ordered according to the following image.
Yes, you are right, this is different from some other prominent systems. Deal with it.
The first track point, track1, is already set, and its keyframes are visible.
Every time you start a track, all visible trackers analyze the image and create new
keyframes. Therefore, turn off the visibility of track1. The four trackers are listed in the
lower portion of the MatchMove Parameters tab. You can click the track name text field
(that is, where it says “track1”) to change the name. You can change the display color of
a tracker by clicking on the color control. The “V” button toggles the visibility of a
tracker.
