Keyframing in Frame Mode
Once you’ve added keyframes to the Tracker palette, there are a number of ways you can
edit them.
Methods of working with keyframes in the Tracker graph:
To add a keyframe: Click the Add Keyframe icon at the upper right-hand corner of the
Tracker graph. It looks similar to the Keyframe icons found in the Edit page Inspector.
This is useful for adding a keyframe to a frame where the window fits the subject well,
prior to moving forward a few frames and making an alteration to the window to follow
the subject that will generate another keyframe.
To move the playhead from one keyframe to another: Click the Previous Keyframe
and Next Keyframe icons at the upper right-hand corner of the Tracker graph. These
controls look similar to those found in the Edit page Inspector.
To delete a keyframe: With the playhead on the same frame as the keyframe you want
to delete, open the Tracker option menu, and choose Delete Keyframe.

A Rotoscoping Workflow
The following procedure demonstrates how to use a window to rotoscope an onscreen feature
that you want to isolate. In the process, it shows how to set up a window for rotoscoping using
the Tracker palette, and discusses some best practices for rotoscoping efficiently.
To rotoscope or manually track a window using automatic keyframing:
1 Create a window to isolate the feature you’re wanting to adjust, and use the tracker to
make it follow the motion of the subject. If the window doesn’t follow the contours of
the subject as precisely as you require, then you can begin manually keyframing its
shape on top of the tracking you’ve done to rotoscope the subject.
2 With the Tracker palette open, click Frame to change the tracking mode.

3 With the playhead at either the first or last frame where the window fits the subject
you’re isolating, you can either click the Add Keyframe icon at the upper right-hand
corner of the Tracker graph, or wiggle any control point by a pixel or two, to add a
keyframe at that frame.
