Visual Controls in the Chroma Keyer Filter
The following controls appear in the Chroma Keyer tab in the Viewer.
 Enable/Disable checkbox: Make sure there’s a checkmark in this checkbox for the
controls you want to use. This lets you add or remove color, saturation, or luma from
the criteria used to define a key.
 Reset button: Click to restore the Color Range, Saturation, and Luma controls to their
default values. Shift-click the button to reset all three controls at once.
 Color Range control: Allows you to fine-tune the range of color that you want to key on.
 Top handles: Let you select a larger or smaller range of colors that are keyed, based
on the original colors you selected with the Select Color eyedropper tool. These
handles correspond to the Width control in the Key on Chroma area of the filter’s
numeric controls.
 Color gradient: Drag left or right within the color gradient to shift the overall hue
of the color range you’ve set with the top set of handles. This corresponds to the
Center On control in the Key on Chroma area of the filter’s numeric controls.
 Bottom handles: Allow you to define the tolerance of your key. These handles
correspond to the Softness control in the Key on Chroma area of the filter’s
numeric controls. Use these handles to gently eliminate additional fringing from
your key while attempting to preserve fine detail around the edges of your
foreground subject.
