Blur & Sharpen > Directional Blur effect


    The Directional Blur effect gives a layer the illusion of motion. In previous versions of After Effects, this effects was called Motion Blur. At Draft quality, the effect is a blur of the image in which each pixel is the unweighted average of its adjacent pixels. At Best quality, the effect uses Gaussian weighting, producing a smoother, more graduated blur. The Direction control 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.
