Basic Key - Alpha Channel

Here is a quick key I pulled in Nuke.  I used the IBK Gizmo for the edge matte and a Primatte as the Core matte.  There are still some holes that need to be filled but I'll do that later.  

I downloaded a Gizmo called the Grad that allows you to take four samples of the greenscreen and gives you back an average.  It's a lot like the IBK color but seems to work a bit better for motion blur and especially after adding a grade node to it. I got the grad node via FXPHD recommendation then downloaded it from here .

Here is what the Grad Node options look like

Here is the Alpha Channel that I got from the IBK Gizmo and Primatte Nodes.  (Still has holes)

Basic Key - Background

Here is the Background I decided to use.  I shot this outside my work with a Canon 5D Mark 2 with the kit lens which isn't my favorite lens by any means to slow for me.

 

Basic Key

I plan on keying this very quick shot and posting a few steps along the way.  Not at all a Tutorial just a few steps here and there. The rack focus is going to be the only tricky part and I don't think that should be to tough on such a short shot anyways.
