Using Selections to Isolate Part of the Image

When part of the front subject is the same color as the color that you are keying out, use a selection to protect this area from the Keyer. For example, if the talent in the blue screen shot has blue eyes, draw a selection around the eyes to prevent the eyes from being keyed out of the image.

To use selections with the Keyer:

1. Select the front layer. See Making Layers the Current Object.
2. Choose Operators | Selections | Draw Selection, and draw a selection around the area you want to protect. See Selection Operators.
3. In the Selection Controls, enable Invert.
4. Play the clip to make sure the selection stays over the area you want to protect. Animate the selection if needed.
5. Apply a Keyer operator. Now the Keyer only affects portions of the image outside the selection.

Note: If you realize that you need to protect part of the image after you have refined the key, simply create the selection, then drag it under the Keyer operator in the Workspace panel so that the selection operator comes before the Keyer operator.
