About the Discreet Keyer

Keying is the process of isolating a region of an image by selecting pixels of a particular color and making those pixels transparent.

Although you can pull a simple key using the Linear Keyer, sometimes you need greater control over the various steps of the process. In such cases, use the Discreet Keyer.

The Discreet Keyer provides basic keying tools used to associate transparency values to a range of colors in the clip. You can use various color models, and adjust the ranges for each color channel individually.

You can use the Discreet Keyer to work directly on the matte to fine-tune the key. You can shrink, erode, or blur the edge, or adjust the entire matte using gain, offset, and histogram controls.

The Discreet Keyer includes color correction tools to remove color spill. For example, you can use color suppression to remove unwanted color, or use color shift to change the unwanted color to another color.

To finesse the final result, you can adjust the blending of the front and background images using the Matte Curves, which are also an integral part of the Discreet Keyer.

You can even use the Discreet Keyer to define a selection based on the matte created by keying an image.
