[Tig] FC Color query

[Steve Hullfish]

To defocus through a shape or a key, you have to go to the ColorFX room.

The easiest way is to choose one of the preset "Defocus Vignette"  
effects from the ColorFX Bin to the right.

OR:

Drag a vignette effect into the workspace, adjust its parameters,  
select the blur effect, drag it into the workspace, drag an Alpha  
Blend in the workspace, then, link the blur to the left input  
"triangle", (the "raw" source is automatically linked to the other  
input) and then link your vignette (or key) to the "alpha" input of  
the Alpha Blend effect. You can also link all the parts together  
first and THEN adjust the parameters. Bob Sliga might have done a  
podcast on this on the old Silicon Color website you could download.

This may seem like a lot of effort, but it allows for lots of  
flexibility and control AND you only have to do this ONCE because you  
can save the effect and use it again and again, only changing the  
parameters.

I don't think you can additionally qualify a Hue, Sat or Luma Curve  
through a window. Seems like a bug to me.

I'll try to figure out how to post a screengrab of the above "defocus  
vignette" effect and the effect itself to the TIG. I've never  
uploaded anything before.
