4.6 Holdout Mask
The holdout mask allows you to define the area of the image that would remain unkeyed, for example a
green area on the TV screen.
First enable the Holdout Mask (OFF by default), then set the area where it is blocked from
chromakey by adjusting its left, right, top and bottom edges using the respective sliders or the left
and right arrow keys.
“Border” allows you to “soften” the mask edges. Increasing the border value creates round soft
gradient edges as shown below.
The Border value ranges from 0 to 100. Use the slider or left and right arrow keys to change the value.
Invert, when turned ON, reverses the default holdout mask (swapping its opaque and transparent
areas). This means that by enabling Invert, the central area is transparent and the border is
blocked.
