Effects and transitions
Filters out noise, often caused by grainy or low light footage, from the alpha channel. Values range from 0
Pedestal
through 100. The default value is 10. 0 does not affect the image. The higher the quality of your source image, the lower
you can set Pedestal.
Matte Cleanup
Shrinks the size of the alpha channel matte. Performs a morphological Erode (fractional kernel size). Choke
Choke
Level Values range from 0 through 100. 100 represents a 9x9 kernel. 0 does not affect the image. The default value is 0.
Blurs the edge of the alpha channel matte. Performs a box blur filter (fractional kernel size). Blur Level values
Soften
range from 0 through 100. 0 does not affect the image. The default value is 0. 1.0 represents a 9x9 kernel.
Adjusts the contrast of the alpha channel. Values range from 0 through 100. 0 does not affect the image. The
Contrast
default value is 0.
Chooses the balance point for the contrast value. Values range from 0 through 100. 0 does not affect the
Mid Point
image. The default value is 50.
Spill Suppression
Controls the saturation of the color channel background color. Desaturates colors that are close to being
Desaturate
fully transparent. Values range from 0 through 50. 0 does not affect the image, The default value is 25.
Controls the amount of spill that is corrected. Values range from 0 through 100. 0 does not affect the image.
Range
The default value is 50.
Adjusts the amount of spill compensation. Values range from 0 through 100. 0 does not affect the image. The
Spill
default value is 50.
Works with the alpha channel to restore the original luminance of the source. Values range from 0 through 100.
Luma
0 does not affect the image. The default value is 50.
Color Correction
Controls the saturation of the foreground source. Values range from 0 through 200. A setting of zero
Saturation
removes all chroma. The default value is 100.
Controls the hue. Values range from -180° to +180 °. The default value is 0°.
Hue
Controls the luminance of the foreground source. Values range from 0 through 200. 0 is black. 100 is 4x.
Luminance
The default value is 100.
Color Key effect
The Color Key effect keys out all image pixels that are similar to a specified key color. This effect modifies only the
alpha channel of a clip.
Nonstandard blue screen (left) and background (center) are combined with Color Key effect (right).
When you key out a color value in a clip, that color or range of colors becomes transparent for the entire clip. Control
the range of transparent colors by adjusting the tolerance level. You can also feather the edges of the transparent area
to create a smooth transition between the transparent and opaque areas.
