Edge Node

Use the Edge node to do one of the following:

Create a greyscale image composed of the edges in an image. You can apply edge-detection to both colour and monochrome clips.
Modify the edges of the key. You can apply the Erode, Shrink, and Blur filters to the edges of the matte.

NoteWhen using the Edge node, values for blur width and height, and shrink and erode width will be scaled following the current resolution of the node. Switching an Edge node input from a PAL clip to an HD clip will update the width and height values automatically.
