Directional Blur--AE

This effect performs a directional blur on an image, giving a clip the illusion of motion.

Direction Specifies the direction of the blur. The blur is applied equally around a pixel's center; therefore, a setting of 180 degrees and a setting of 0 degrees look the same.

Blur Length Specifies how much to blur the image.
