Fast Blur effect
Fast Blur is a close approximation of Gaussian Blur, but Fast Blur blurs large areas more quickly.

Gaussian Blur effect
(High bit-depth) The Gaussian Blur effect blurs and softens the image and eliminates noise. You can specify that
the blur is horizontal, vertical, or both.
Ghosting effect (Windows only)
The Ghosting effect overlays transparencies of the immediately preceding frames on the current frame. This effect
can be useful, for example, when you want to show the motion path of a moving object, such as a bouncing ball.
Keyframes cannot be applied to this effect.
Sharpen effect
The Sharpen effect increases the contrast where color changes occur.
Unsharp Mask effect
The Unsharp Mask effect increases the contrast between colors that define an edge.
Original (left), and with effect applied (right)
Radius The distance from the edge at which pixels are adjusted for contrast. If you specify a low value, only pixels
near the edge are adjusted.
Threshold The greatest difference between adjacent pixels for which contrast isn’t adjusted. A lower value produces
a greater result. A value that is too low causes contrast for the entire image to be adjusted and can generate noise or
cause unexpected results.
