Adding new track points (Pro only)
To use tracking data with expressions, you may want to track additional features. You can add track points by
choosing New Track Point from the panel options menu. Each new point tracks position only. You cannot apply the
additional tracking data directly to a target layer, but you can refer to the data in expressions. As with any tracking
data, it is stored with the motion source in a track and appears as keyframes in the Timeline panel. You generally
select the Raw tracking type if you plan to add track points and later use the data in expressions.

To move or resize the track point (Pro only)
In setting up motion tracking, it’s often necessary to refine your track point by adjusting the feature region, search
region, and attach point. You can resize or move these items independently or in groups by dragging with the
Selection tool, whose pointer icon changes to reflect one of many different activities. To help you define the area to
be tracked, the image area within the feature region is magnified to 400% while you move the region.
To zoom into or out of the feature region in a Layer panel, push your mouse wheel forward or backward.
