The Emboss effect sharpens the edges of objects in the image and suppresses colors.
The
effect also highlights the edges from a specified angle.
Direction
Specifies the apparent direction in which the highlight source is shining, in
degrees. A setting of 45° causes the shadow to be cast in the northeast direction.
Relief
Specifies the apparent height of the embossing, in pixels. The Relief setting
actually controls the maximum width of highlighted edges.
Contrast
Specifies the sharpness of the image content’s edges. At lower settings, only
distinct edges show the effect. As you increase the setting, the highlight becomes more
extreme.
Extract
The Extract effect removes colors from a video clip, creating a textured grayscale
appearance. Control the clip’s appearance by specifying the range of gray levels to
convert
to white or black.
To specify Extract settings:
1
Drag the two triangles underneath the
histogram
(a diagram showing the number of
pixels at each brightness level in the current keyframe) to specify the range of pixels
converted to white or black. Pixels between the triangles are converted to white. All other
pixels are converted to black.
2
Drag the softness slider to introduce levels of gray into the pixels that have been
converted to white. Higher softness values produce more gray.
3
Select the Invert option to reverse the range that is converted to white and black.

Facet
The Facet effect clumps pixels of similar color values in cells for a painterly effect.
Keyframes cannot be applied to this effect.
Fast Blur
Use the Fast Blur effect to specify how much to blur an image. You can specify that the
blur
is horizontal, vertical, or both. Fast Blur blurs areas more quickly than Gaussian Blur.
Field Interpolate
The Field Interpolate effect recreates a missing
field
(usually the odd or even scan lines,
common to television or interlaced monitors, that have been dropped during capture) by
using line averages. This effect can be useful for full-screen output, where a missing field
is
likely to be noticeable.
Find Edges
The Find Edges effect identifies the areas of the image that have significant transitions and
emphasizes the edges. Edges can appear as dark lines against a white background or
colored lines against a black background. When the Find Edges effect is applied, images
often look like sketches or photographic negatives of the original.
Invert
Inverts the image after the edges are found. When Invert is not selected, edges
appear as dark lines on a white background. When Invert is selected, edges appear as
bright lines on a black background.
Gamma Correction
The Gamma Correction effect lightens or darkens a clip without substantially changing
the shadows and highlights. It does this by changing the brightness levels of the midtones
