The CC Radial Fast Blur is a simpler version of the CC Radial Blur. It only creates the Straight Zoom blur and you have no control over the quality.
You can adjust the center of the effect.
Amount increases the intensity of the blur. I find that 100 is where it is essentially unusable.
You can change the type of zoom, there are three modes.
Straight – Simple, the most basic use.
Lightest – Only blurs the light values in a frame
Darkest – Only blurs the darker values in a frame
