Chroma Key nodes

scourage · Post by **scourage** » Sat Jul 22, 2006 10:44 pm

This is an unofficial build for windows that has several new nodes implemented. I'd love to get some feedback on it.

The keyers allow for you to adjust the amount of tolerance per channel for the selected key color as well as the falloff size and strength.

the spill suppression works with the common backgrounds (green/blue) as well as red.

The erode/dialte tool can erode/dialte a mask a little bit to get more/less foreground in a composite

the info tool has several informative things about the render drawn to the screen.

Current patch has:
-matte node menu group
-RGB difference matte node
-YUV difference matte node (also called luminence matte?)
-HSV difference matte node
-YCbCr difference matte node (chroma key)
-YUV color space seperator node
-YUV<->RGB conversion functions
-YCbCr color space seperator node
-YCbCr<->RGB conversion functions
-RGB spill correction
-Info overlay node
-erode/dialte node (courtesy of Broken!)

PS. The dilate/erode node was written by brecht van lommel. I just cleaned it up and made a patch

Quite likely, but not with absolute certainty,

OK. I'm thinking many time why some cool patches didn't be implement to CVS... For me this is very strange...

If a patch is coded badly/hackishly or is buggy it generally won't be applied.

I'm fairly sure Bobs patches will be applied in the near future though...

OK. Now I understand it better...
