Setting up to track a window over a woman’s face
3 Open the Tracker palette, and choose Point Tracker from the bottom right pop-up.
Choosing the Point Tracker
4 Before you start tracking, choose what types of motion you want to track and apply to
the window you’re working on. You can choose from among Pan, Tilt, Zoom, Rotate or
Perspective 3D. Which methods of transformation can be applied depend on how many
points you add to track.
Choosing what type of motion to analyze
5 Click the Add Tracker button. A new tracker crosshairs appears in the Viewer in the
center of the frame.
Clicking the Add Tracker Point icon
6 Move the pointer directly over the tracker crosshairs, and when it turns into the move
cursor, click and drag to move the crosshairs to line up on top of the feature you want
to track. For the best results, this should be a high-contrast detail such as a corner, the
end of a line, a small shape like a pebble, or a jagged detail. Unlike other point trackers,
there is no inside or outside region to separately adjust, there’s only the one crosshairs
that you need to align. In this example, this first crosshairs is placed at the inside of her
stage left eyebrow (the corner of her eye would introduce too much jitter as the tracker
will pick up her blinks).
