Apple Motion 2 - Manual (Page 718)

718 Chapter 10 Using Filters
Sides: Sets the number of sides of the lens aperture, if Circle is set to Off. Values range
from 3 to 12.
Rotation: Sets the angle of rotation of the polygonal lens aperture, if Shape is set to
Polygon.
Aspect Ratio: Sets the aspect ratio of the lens aperture. Values range from 0 to 2.
Crop: Toggles whether or not the blur will be cropped at the object’s original border.
Dashboard controls
The Dashboard contains the same controls as the Inspector, with the exception of the
Crop checkbox.
Directional Blur
Blurs an object out along a specific angle. This filter creates a blurred streaking effect.
Note: Remember that the more filters you use in a project, the more you impact the
performance of Motion.
Parameters in the Inspector
Amount: Sets the radius of the blur. Values range from 0 (no blur) to 32.
Angle: Sets the angle of the direction of movement.
Crop: Toggles whether or not the blur is cropped at the object’s original boundaries.
A Fun Effect That Can Be Used With All the Blur Filters
Duplicate the original layer in the Layers tab, then use one of the blend modes to
combine the original image with the blurred image. This effect is especially
interesting when used with a directional blur, as it creates a different sort of effect
than the filters in the Glow category. A similar effect, though without the directional
control, can be achieved using the Soft Focus filter, described on page 721.
