Edge

Edge allows you to extend the proper color out over transparent edges or areas with a lot of motionblur without eroding away the nice detail. This edge extend has some more advanced features like splitting the core matte and final key which allows you to work on motion blur without effecting small details like hair or a swinging rope for example. There is also more control over how you blend the core detail to the extended edge color. This was shown to me years ago by an old comp sup I had and is the same as the edge extend by Frank Reuter. This is my version of it that has evolved a little bit over the years.

Version History

  • 5.2 – Fixed error when edge is first placed in the node graph. This was due to the copy nodes inside throwing an error because there is not alpha on creation of the node.
  • 5.1 – Added contact and version info. Added edge preview for regain.
  • 5.0 – Changed order of blend and blur knobs for better workflow. Added mix knob to color panel.
  • 4.0 – Renamed inputs from artist feedback
  • 3.0 – Added color wrap panel to help blend BG color into transparent edges.
  • 2.0 – Added edge smooth knob for extreme motion blur?
  • 1.0 – Compiled edge into a gizmo
