Use the Matte Edge effect to create an image based on the detected edges, or use it to modify the edges of a matte to help in creating a key.

You can access the Matte Edge effect in the following ways:

• As a Batch node. This node accepts a front clip and a matte clip as inputs.
• As a Modular Keyer node. You can add the Matte Edge node to any part of the pipeline except the Front pipe of the CBlend node. The Edge node is not appropriate for this pipe because its result is a matte.
