Adding Media to Shapes
311
You can apply motion blur to filters and Natural media by pre-composing the filter or
Natural media track and applying motion blur to the pre-composition. For more information
on pre-composing, see “Working with Pre-Compositions” on page 181.

Tip: Motion blur is a processor-intensive feature. Turn motion blur off while you work, and
then enable it just before rendering. The global Motion Blur button on the timeline lets you
switch turn the motion blur on or off for all tracks.
To apply motion blur:
Do one of the following:
1. From the Motion Blur tab (Controls window), select the Enable Motion Blur option to
apply motion blur to the track.
2. Click the Motion Blur button on a track to turn motion blur on or off.
n
The controls in the Motion Blur tab do not affect motion within the media; a blur is created
based on the motion of the Shape track or container.
3. Use the Shutter Angle controls to adjust the shutter (like the shutter on a conventional
film camera). Increase the angle to create a wider blur and decrease the angle to get a
thinner blur.
4. From the Smoothness menu, select one of the following to determine how many
samples are taken between the shutter opens and closes:
• Low: Uses the fewest samples.
• Medium: Limits smoothness while working in Draft mode.
Shutter Angle=180
Shutter Angle=300
