The Control Edge tool lets you move, stretch, and soften the edges of a matte. You can widen an edge, offset it toward the interior or exterior, and blur its inner and outer extremities separately.
(a) Original matte (b) Modified with Control Edge (c) Alpha Remapped
The Control Edge tool has the following parameters:
| Use: | To: |
|---|---|
| Outer Distance | Control the width and offset of the outer edges. |
| Inner Distance | Control the width and offset of the inner edges. |

| Inner Softness | Add blur to the inside extremities of edges. |
| Link Softness | Link the Outer and Inner Softness sliders. By default, the Link button is enabled. |
