Restore Fringe
This restores the edge of the matte around the keyed subject. Often when keying, clipping occurs
around the edge of the subject where there is hair. Restore Fringe brings back that edge while
keeping the matte solid.
Erode/Dilate
Expands or contracts the matte.
Blur
Softens the matte.
Clean Foreground
Fills slightly transparent (light gray) areas of the matte.
Clean Background
Clips the bottom dark range of the matte.
Replace Mode
Determines how matte adjustments restore color to the image.
– None: No color replacement. Matte processing does not affect the color.
– Source: The color from the original image.
– Hard Color: A solid color.
– Soft Color: A solid color weighted by how much background color was originally removed.
Replace Color
The color used with the Hard Color and Soft Color replace modes.
The Delta Keyer Fringe tab
Fringe Tab
The Fringe tab handles the majority of spill suppression in the Delta Keyer. Spill suppression is a form
of color correction that attempts to remove the screen color from the fringe of the matte.
Spill is the transmission of the screen color through the semitransparent areas of the alpha channel. In
the case of blue- or green-screen keying, this usually causes the color of the background to become
apparent in the edges of the foreground subject.
