Blurs: G Radial Blur
G Radial Blur is two different blurs in one: zoom blur; and spin blur. The zoom blur simulates the motion blur of tracking or zooming quickly into your subject. The spin blur distorts your image as if it were rotated quickly around the centre point. Unlike the Radial Blur filter that comes with FCP, the G Radial Blur filter offers additional controls for setting the amount of blur and for keeping the centre of the blur radius sharp.
