System information

5. Use the keyframe controller at the bottom of the Track Motion window to establish distinct track
motion settings throughout the duration of the track.
During playback, intermediate frames are interpolated to create smooth motion.
Expand the Keyframe interpolation heading on the left side of the window and drag the
Smoothness slider to adjust the interpolation.
Use the Default Track Motion smoothness control on the External Control & Automation tab of the
Preferences dialog to set the default Smoothness value for new keyframes.
Creating a shadow effect
The shadow effect creates a drop shadow under an object, window, or title. A shadow is especially effective
under a picture-in-picture window.
This procedure assumes that you have already created an event on the track above the background video
to be used as an overlay.

Motion window is displayed.
2. Select the 2D Shadow row in the keyframe controller. When the 2D Shadow row is selected, shadow
controls are displayed in the Track Motion dialog.
Select the 2D Shadow check box to apply the shadow so you can see the results of your shadow in
the Video Preview window, or clear the check box to bypass the shadow.
3. Use the 2D Shadow controls on the left side of the window to set the color and appearance of the
shadow:
