Gaussian Blur effect
The Gaussian Blur effect blurs and softens the image and eliminates noise. You can specify that the blur is horizontal,
vertical, or both. (Gaussian refers to the bell-shaped curve that is generated by mapping the color values of the
affected pixels.)
Gaussian Sharpen effect
The Gaussian Sharpen effect sharpens a clip by a large amount; the effect is similar to that of choosing the Sharpen
effect several times. Keyframes cannot be applied to this effect.
Ghosting effect
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.
Radial Blur effect
The Radial Blur effect produces a soft blur by simulating the effect of a zooming or rotating camera. Select the Spin
blur method if you want to blur along concentric circular lines, as if rotating the camera. Select the Zoom blur
method if you want to blur along lines radiating from the center. Drag the dot in the Blur Center box to change the
origin of the blurring. You can also set the Amount of the blur from 1 to 100. With the Spin blur method, this value
reflects the degree of rotation; with the Zoom blur method, this value reflects the intensity of the blur.
Sharpen effect
The Sharpen effect increases the contrast where color changes occur.
Sharpen Edges effect
The Sharpen Edges effect finds the areas in the clip where significant color changes occur, and sharpens them.
Keyframes cannot be applied to this effect.
Unsharp Mask effect
The Unsharp Mask effect increases the contrast between colors that define an edge. Use the following controls:
Radius
Specifies the depth of pixels that will be affected at an edge. If you specify a high value, more of the pixels
surrounding the edge are adjusted for contrast. If you specify a low value, only pixels at the edge are adjusted.
Threshold
Specifies a tolerance to define edges and prevent overall contrast adjustment that might generate noise or
cause unexpected results. Values define the range of contrast allowed between adjacent pixels before contrast is
adjusted. A lower value produces a more pronounced effect.
