View Full Version : RGB split

06 June 2004, 05:25 AM
Is it possible to split the RGB channels, add separate operators on them and then combine them? If not, are there any plug-ins for this?

I'm using Combustion 2.1.

Yes you can. The way I have done it is to connect the source footage (or paint in this) into 3 Discreet Color Correctors. I have set the Histogram output for the various channels as:

Red = Red 255, Green 0, Blue 0
Green = Red 0, Green 255, Blue 0
Blue = Red 0, Green 0, Blue 255

You then apply whatever operators you need and set the Transfer Mode to Screen for all layers.

Attached is a combustion 3.02 cws set up and ready to be examined for other users.

Doh just saw that you are on 2.1 here is an image of what I did for the Red Channel on the Green Output.

Thanks a lot man. I just figured that it would be a layer setting or an operator thingie.

Much appreciated.

maybe there's an other way to do this using the compound RGB operator, first apply your effect to your layer, then a compound RGB, and set, if you want you effect to be only on your red channel, the green and blue operators to "set", your green and blue inputs to "green" and "blue", at "G and B layer" pick your footage. this has to cancel the first operator for those channels, and now your effect is only on the red channel
it doesn't solve everything but could help :)
