Tracking paths 159
4 Click OK.
In combination with motion tracking, this feature is most useful
in blurring out elements that you do not want to show in your
video. Some examples of such are blurring out faces of people
to protect their identity and covering vehicle license plates for
security.
Using the Path Library
You can add motion behavior to a clip in the main video track or in the
overlay track by dragging a preset path from the Path Library to the clip
in the Timeline.
