Adjusting Matte Controls

Matte Density

When refining your composite, the matte density setting should always be adjusted first.
This setting strengthens the general opacity of the black areas of the matte, preventing areas
of the background to show through the foreground.
To adjust the matte density:
1 Select 'matte' in the main menu buttons.
2 In the 'monitor out' section, press 'combined matte'. You will see the foreground subject
appear as a black silhouette on a white field.
3 Using the control knob, decrease the matte density until you see details within
the black start to become gray. Now increase the setting until the gray areas
change to black.
4 Select the program output in the monitor out settings.
Any show through that was present prior to adjusting matte density should now be almost,
or completely, gone.

Black Gloss

Sometimes there may be dark areas of your foreground that have bright highlights which are
reflecting the backing color. These highlights can appear gray in your matte, which will cause
those areas in your foreground image to become transparent in your composite. The black
gloss setting helps to remove these areas from the matte.
Increase the black gloss setting while observing the combined matte output until these
reflective areas are no longer visible in the matte.
TIP If the matte is already opaque and there are no highlights showing, it's worth
decreasing the black gloss level until you see the highlights, then increasing and
stopping as soon as they are no longer visible. This is because the lowest setting that
can be achieved will result in the cleanest, most convincing composite. This is true for
many of the matte controls.

Red, Green and Blue Density

As matte density and black gloss settings are increased, dark edges can form around
foreground objects. To compensate, the density of the color channels surrounding the edge
of the foreground objects can be adjusted.
For example, if your backing color is green, the colors available to adjust are red and blue.
If your backing color is red, the adjustable colors are green and blue. Adjusting these fine color
density controls can help clean up dark edges.
