Apple Motion 3 - Manual (Page 862)

862 Chapter 10 Using Filters
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.
Mix: Sets what percentage of the original image is blended with the blurred image.
Values range from 0 to 100%.
HUD Controls
The HUD contains the same controls as the Inspector, with the exception of the Crop
checkbox.
Gaussian Blur
The Gaussian blur is the softest blur effect you can apply, and is one of the most
frequently used blur effects. By default, it affects the entire image uniformly, although
you can control the amount of horizontal and vertical blur independently.
Blur Filters Without the Mix Parameter
Some blur filters don’t have the Mix parameter. You can duplicate the effects of the
Mix parameter by copying the original layer in the Layers tab, then changing the
filtered image’s Opacity 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 867.
