Inputs
Outputs

This node keys an input based on hue, saturation, and luminance ranges. Keying removes parts of the image that fall within these defined ranges by setting the Alpha to a value of zero. The parameters in the Rolloff section extend these ranges with a soft rolloff function: linear, ease in, ease out, smooth, or Gaussian.

For example, this node is useful when trying to isolate a foreground from a green screen.

Parameters ¶

Signature

The layer type that the source accepts.

See Signatures for more information.

Method

Whether to use the legacy Chromakey or the channel separation key.

Invert

Inverts the resulting matte. This is equivalent to appending an Invert COP to the Matte output of this node.

Key ¶

Hue/Saturation

The hue and saturation ranges.

Tip

Click and then click on the layer to set the Hue/Saturation.

Luminance Range

The luminance range.

Screen Color

When using Channel Separation, the color to key out.

Threshold

When using Channel Separation, this thresholds the resulting matte. The threshold is equal to the midpoint.

Any values above 0.5 become 1 and any values below 0.5 become 0 if Threshold When is Greater, Threshold is 0.5, Width is 0, and the output is (0,1).

Width

When using Channel Separation, this is the range on both sides of the threshold that determines the input minimum and maximum.

A Threshold of 0.5 with a Width of 0.2 represents an input range of (0.4,0.6).

Rolloff ¶

Hue

Extends the hue range on either side by the rolloff size. Values within the rolloff threshold are interpolated by the Interpolation value.

Saturation

Extends the saturation range on either side by the rolloff size. Values within the rolloff threshold are interpolated by the Interpolation value.

Luminance

Extends the luminance range on either side by the rolloff size. Values within the rolloff threshold are interpolated by the Interpolation value.

Interpolation

The rolloff function to use.

Visualize ¶

Preview

Colors the result of the keying operation with Preview Color. The pixels being colored aren’t keyed out.

Preview Color

When Preview is turned on, this is the color to apply to the preview.

Premultiply

Multiplies the input image by the matte that this node generates. This discards the parts of the image being keyed out.

Inputs ¶

source

The original layer to key.

Outputs ¶

keyed

The output layer with the key applied to it.

matte

The output matte. This is a mono layer that represents which parts of the image were keyed out. For example, you can do more processing to it and then use a Premultiply COP to key your source layer with the matte you created.
