You mean ISO noise?

 

[Kyle Presley]

Chromatic aberration and noise are two entirely different things.

I know, just wanted to make sure, cause many ppl mix those things!

??? who mixes those things up??? hahah

one is color fringing..

the other is noise...

The kind of fringe is a side effect on some sensors and not the same as CA, the latter is different colors refracted to different positions due to their wavelength. You can easily correct that in Apple's Color, for example.
The first one can be seen anywhere in the image (and I've never seen it on the R1), the latter is a weakness of some lenses and more obvious in the corners.

Uli... Could you please explain how you are using COLOR go fix Chromatic Abberation?

Get your hands on Nuke, then try this plugin in the inverse mode. They've got a demo that you can probably test with.

Nuke takes a bit to get used to if you if you haven't used node based progs, but it does have native .r3d support out of the box.

EDIT: I misread your post. I thought you were trying to kill it from a shot, but you were actually suggesting it as a RCX feature. If RCX supports OFX plugins, this would be pretty easy for a third party to develop.

@Kim: Just separate to R, G and B in the VFX room, scale them separately just a tiny wee bit and unite the channels again. Quite simple – if ii's just CA, which normally means the different colors are not exactly the same size on the edges, but fit in the center.

Thanks Uli... Glad that this is the technik I knew.

It's easily done with a secondary correction by selecting the color range, putting a soft edge on the key and matching the offending noise to white or some other color that helps it roll off naturally.
