Suppressing Spill
After you create a key and key out any trouble areas, some of the background
color may have spilled over the edge of the key. Use the Spill controls to
suppress or disguise color spill in the front image.
To gesturally remove color spill:
1 Set a Player view to Tool Output and, with the selection on the Keyer
super tool node, cycle to Comp Output—see
Cycling Through Inputs and
Outputs on page 71.
2 Select Spill from the Sampling box or press S .
3 Remove any color spill. Click anywhere in the Player, and modify the
parameters that appear by dragging the sliders; you do not need to click
a specific area.
To: Drag:
Set the range for the removal of color spill along the edges of the key.
Drag right to soften the edge and remove color spill further into the
key. Drag left to harden, or create a thinner, edge. Range
Modify and suppress colors that are adjacent to the primary sample. Hue
NOTE To reset Spill and Blend parameters, click the Reset button, below the Edge
Balance trackball.
Modifying Blend
Using the Blend parameters you can gesturally modify the luminance at the
edge of the key, so that it blends with the luminance in the background image.
For example, when the front image is darker than the back image, you can
use the Blend parameters to lighten the edge of the key.
With the Blend Luminance controls, you can adjust the edge blending and
maintain the edge detail. Adjusting the Edge Size amount uses pixel analysis
to determine the extent of the adjustment.
