Leave Color effect

The Leave Color effect removes all colors from a clip except those similar to the Color To Leave. For example, a
movie of a basketball game could be decolored except for the orange of the ball itself.

Amount To Decolor

How much color to remove. 100% causes areas of the image dissimilar to the selected color to

appear as shades of gray.

Tolerance

The flexibility of the color-matching operation. 0% decolors all pixels except those that exactly match

Color To Leave. 100% causes no color change.

Edge Softness

The softness of the color boundaries. High values smooth the transition from color to gray.

Match Colors

Determines whether colors’ RGB values or HSB values are compared. Choose Using RGB to perform

more strict matching that usually decolors more of the image. For example, to leave dark blue, light blue, and
medium blue, choose Using HSB and choose any shade of blue as Color To Leave.

Luma Corrector effect

(High bit-depth) The Luma Corrector effect lets you adjust the brightness and contrast in the highlights, midtones,
and shadows of a clip. You can also specify the color range to be corrected by using the Secondary Color Correction
controls.

ments (Luma), display of the alpha matte (Mask) or a tritone representation of where the shadows, midtones, and
highlights fall (Tonal Range).

Show Split View

Displays the left or upper part of the image as the corrected view and the right or lower part of the

image as the uncorrected view.

Layout

Determines whether the Split View images are side by side (Horizontal) or above and below (Vertical).

Split View Percent

Adjusts the size of the corrected view. The default is 50%.

Tonal Range Definition

Defines the tonal range of the shadows and highlights using threshold and threshold with

falloff (softness) controls. Click the triangle to display the Tonal Range Definition controls. Drag a square slider to
adjust the threshold values. Drag a triangle slider to adjust the softness (feathering) value.

Definition sliders.

Tonal Range

only, midtones only, or shadows only.

black.
