Apple Motion 4 - Manual (Page 966)

Gaussian blur is entirely appropriate for most motion graphics tasks, and can be animated
for a variety of focus-control effects. However, to more accurately simulate camera focus,
the Defocus filter may be more appropriate. For more information on the Defocus filter,
see

HUD Controls
The HUD contains the following controls: Amount, Horizontal, and Vertical.
Gradient Blur
The Gradient Blur filter allows you to control the blurred region of an image by creating
a graduated blur between two points. Point one is the beginning of the blur, and the
point at which the image is at its sharpest. Point two is the end of the blur, and the point
at which the image is at its blurriest, depending on the value set in the Amount parameter.
