The Edge tool is one of the tools used for matte cleanup tasks during the keying process. It lets you shrink, erode, or blur
the edge of the matte, as well as isolate the edge of the matte, or invert the matte.
Because the Edge tool affects the alpha and is applied to the output of a keyer tool, such as the Luma Keyer or the Diamond
Keyer, your dependency graph should include, as a minimum, a source and a keyer.
The Edge tool contains the following parameters:
| Use: |
To: |
| Edge Detect |
Isolates the edge of the key. The numeric field takes values representing the width of the detected edge based on a 0% to
100% float. Edge width can depend on image size.
|
| Invert |
Invert the matte. |
| Shrink |
Reduce the edge width. The numeric field takes values representing the pixel width of the shrink filter (from 0.000 to 30.000
float).
|
| Erode |
Blend (soften) the light and dark edges. The numeric field takes values representing the pixel width of the erode filter (from
0.000 to 30.000 float).
|
| Blur |
Reduce the edge width. The numeric fields take values representing the pixel width of the blur filter along the X-axis and
the Y-axis (from 0.000 to 30.000 float).
- Link: Blurs the width and height proportionally. Default is on.
- Gaussian: Default is on, but can be changed to a box blur filter.
