4 Depending on the mode you selected in the previous step, adjust the controls to alter
your matte:
In Scrub Boxes mode, drag any side of the outer graph in the Chroma control to alter
the range of hue and saturation contributing to the matte’s edge softness (transparency
around the edges of the key).
Note: In Scrub Boxes mode, you can also drag the two lower handles of the Luma
control to alter the range of lightness and darkness contributing to the matte’s edge
softness.
In Manual mode, drag any side of the outer graph in the Chroma control to alter the
range of hue and saturation contributing to the mattes edge softness. Drag any side
of the inner graph to alter the range of hue and saturation contributing to the matte’s
tolerance (core softness). Drag in the center of the inner graph to rotate the graph to
a new position in the color wheel.
Note: In Manual mode, you can also drag any of the four Luma control handles. The
two upper Luma handles alter the range of lightness and darkness contributing to the
mattes tolerance (core transparency); the two lower handles alter the range of lightness
and darkness contributing to mattes edge softness.
