Matte Density Controls
THE “MORE” CONTROLS
Matte Density Controls for Print-Through, Dark & Glowing Edges
These controls are used to adjust the density or opacity of the foreground objects. The density of a foreground
object is determined by its matte (alpha) value. A completely opaque object's matte will be white, a completely
transparent object's matte will be black, and a partially transparent object's matte will be gray.
With the Matte Correction process enabled (click the Matte button to
enable), all kernel-based processes become available. These include
Roto-Screen Correction, Film Correction, Video (DV) Correction,
Shadow Processing, and some of the Matte Density and Clean-Up
controls. With the Matte Correction process disabled, available functions will be pixel-based only (with the
exception of Matte Shrink and Blur).
Set these controls while viewing the matte or composite:
Choose Matte Density from the Slider Controls pop-up menu.
• Brights: Use this control to adjust density in bright foreground objects.
Warning: Advancing this control too far can cause hard, dark edges around foreground subjects.
• Darks: Use this control to adjust density in black glossy or dark foreground objects.
Warning: Advancing this control too far can cause hard, dark edges around foreground subjects.
• Shrink/Bias: (Only available when Matte Correction is DISABLED.)
Use the Shrink control to shrink the matte to possibly reduce hard edges. A value set to
10 is the equivalent of a 1-pixel shrink. Use the Bias control to influence the matte shrink
process from one or more of the following directions: left, right, top, bottom.
