IBKCleanPlate v1.0

With this Gizmo, you can create a clean plate of your green/blue screen, using the classic IBKColor node of Nuke.

There are 2 operations:

1. BLUR AND UNPREMULT

Based on the tutorial http://www.nukepedia.com/written-tutorials/simple-clean-screen-using-ibk-colour-with-un-premult written by Satheesh R, it uses the unpremult-blur-premult operation to create the clean plate.

2. IBKCOLOR STACK

Based on the tutorial https://www.youtube.com/watch?v=izwwic6Q7cs by the great Tony Lyons :), it's using the stack of IBKColor.

MASK: 

Sometimes, can happen that is hard to remove markers or fine details.

In this case, just connect a roto to the relative input and create a roto shape around the markers.

You will get the markers included in your clean plate. Just remember to enable the mask
