Hide a face with the “cops” effect
You can use the Track Matte Key effect to blur faces, license plate numbers, or other identifying features. Television
programs use this effect to protect the identities of their subjects. See the video tutorial
Advanced Effects with the Track
Matte Key by Jeff Schell.
Make skin appear smoother
See the video tutorial, Smooth an Extreme Closeup , by Curt Wrigley.
Zoom and pan a still image
Zooming and panning still images have come to be known as “the Ken Burns” effects, since documentarian Ken Burns
has made extensive use of them. For a tutorial on zooming and panning still images, see
The Ken Burns Effect on the
Digital Video Editing blog.
Place lightning over part of a clip
You can make lightning appear over only part of an original clip.

Create a Jacob’s Ladder
You can create a Jacob’s Ladder effect. The lightning bolt snaps back to a position along the start line after it has been
pulled in a given direction.
1 Apply the Lightning effect to a clip.
2 In the Effect Controls panel, click the triangle next to Lighting to expose the Lightning controls.
3 Experiment with different combinations of settings for these three controls.
• Stability,
• Pull Force,
• Pull Direction.
A Stability value that is too low doesn’t allow the lightning to be stretched into an arc before it snaps back. A value that
is too high lets the lightning bolt bounce around.
