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.
