Help with Shuffle, ShuffleCopy and Copy nodes

Hi,

I just started learning Nuke and I am pretty confused with these 3 nodes. I tried watching the Node Reference Library from Digital Tutors and I still don't understand it that well.

I get that Shuffle copy is used to copy the RGB values from one pass to another. Is that the only use of the node?

What exactly does these nodes do and how can I use them to make my comp better?

I have seen scripts with tons of these nodes, but I dont understand the purpose.

Please help.

I would post your question in the Compositing forum here:

Long story short:
Shuffle: lets you change the RGB to be all RRR or all GGG or change your depth to rgb channel, etc. Handy for making a mask pass composed of Red, Blue, Green masks to a White/Black image to only show Red as White and everything else black and use it as a matte, etc. Looks hard, but I only use the upper left check boxes most of the time.

Copy: Copy one channel (like zdepth or alpha) into another channel

I'd find some tutorials on using it and it will start to make sense.

wrong forum.

shuffle copy is used to copy channel values, including alpha, from 1 plate to another.

shuffle is used as a mode of extracting a channel(edit: or multiple)to the forefront that you wish to work with/on.

copy is a channel mixer that you can use with ALL kinds of channels, including Z, UV and so forth.

The uses are widespread from distortions to keying and on and on.

thats the jist of it.
