Extracting a Single Color

Use the channel mode to extract one of the three primary colors or extract a custom color sampled from the clip.

This option can give especially good results when keying transparencies such as glass or smoke.

To pull a key by extracting a primary color:

1. In the Keyer Controls panel, click Key.
2. Select Channel from the Keyer Mode list.

The Channel controls appear.



3. Select the color to key out (Red, Green, or Blue) from the Channel Color list.
4. Adjust the softness of the key.

The softness value determines how much of the key-in clip is partially transparent in the matte. Softness is used to create a smoother transition between the front and back clips in the composite clip.

5. Enable More to increase the softness around the edge of the key.

To pull a key by extracting a custom color:

1. In the Keyer Controls panel, click Key.
2. Select Channel from the Keyer Mode list.

The Channel controls appears.



3. Click the picker, and click a point in the image to sample that color. You can also click and drag the picker across a region to obtain the average color of the pixels sampled. Try selecting different colors within the background area to get the best result.

Note: To keep shadows, click just outside them. To remove shadows, click inside them.

The sampled color appears in the color box.

4. Adjust the softness.
5. Adjust the Color Spread to extend the range of colors that is keyed out.
