INPUT CLIP
The image in which Sobel edges are to be found.
Radius (Min: 0.0 Max: 10.0 Default: 1.0)
Specifies the radius of a region across which a Sobel operator will be applied to make
each pixel of 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 the
radius is large. Large values will also significantly increase processing time. However,
large values are unlikely to be required for most effects.
Negative Edges (Default: Off)
Off=0: the edge image is derived from the positive input clip.
On=1: the edge image is derived from the negative input clip.
Over Image (Default: Edges)
The style of combining the edges with the original image. An enhancement for
v3.0.
