From Dennis Radeke’s The Genesis Project:
Stu Maschwitz is really one of the top guys around in the world of After Effects and he evidently is also a scripting genius since he strung together a bunch of Cycore effects that are included with After Effects to give you a color correction tool with out putting out some coin.So this is a plug-in, but only kind of, since you access it through the scripts folder. Don’t let that scare you off though, because you don’t deal with ‘scripts’ at all. I like the Rebel CC because it gives you a step-by-step process to better color, but in very easy, small steps.
Here’s the video that David Basulto did on the Rebel CC, and I recommend that you give it a look before you download the Rebel CC script.
If you’re the kind of person that doesn’t care about ‘no stinkin’ videos,’ you can get to the Rebel CC page here.
I think rebel cc is good plug-ins for color correction
