INPUT CLIPS
The clip in which gradient edges are to be found.
Radius (Min: 0.0 Max: 10.0 Default: 1.0)
Specifies the radius of a region. The extent to which image colors change across this
region gives the image gradient, which is used to make the output image. Large values will
tend to make small (near pixel size) features not effect the edge image, but the edge
image will be sort of blurry when radius is large.
Negative (Default: Off)
Off=0: the edge image is light edges on a dark background.
On=1: the edges are dark on a light background.
Over Image (Default: Edges)
The style of combining the edges with the original image. An enhancement for
v3.0.
