Following is a description of how the Hue, Width, Softness, and Low Sat sliders
affect what color is keyed out. You can adjust these values by clicking and dragging
their sliders right or left, by clicking on the numeric value and dragging the mouse
up or down, or by typing in a numeric value:
Now that you’ve mastered the basics of keying out colors using the Keyer Settings
panel and its functions, try experimenting with your own video sources.
Hue The Hue value is a number from 1 to 360 that
corresponds to the degree on the color wheel. A value
of
1
is pretty close to chroma key blue. The value for
chroma key green is around 230 . By clicking on the
Hue
slider and dragging it right or left, you see the
sliver of color move around the Keyer picon in the
Keyer Settings Panel.
Width
Adjusts the size of the sliver of color in the
Keyer
picon, affecting the number or range of colors keyed
out. A value of
1 is a small sliver, while a value of 40 is
a large sliver. By clicking on the Width slider and
dragging it right or left, you see the size of the sliver of
color grow and shrink.
Softness Can be used to make the edges of a chroma key look
soft and natural. By clicking on the
Softness
slider and
dragging it right or left, you see the edges of the sliver
of color in the
Keyer
picon change in degrees of
softness.
Low Sat Controls how much of the neutral colors in the center
of the color wheel are eliminated. By clicking on the
Low Sat slider and dragging it right or left, you see a
circle of color in the center of the Keyer picon grow or
shrink, changing what colors are keyed out. The
higher the
Low Sat
value, the bigger the circle of color
that is keyed out.
