That would be a colorgrade and not color correction.
I think Austinv wants a colorgrade.So therefor Colorista would be good
If speed is an issue you can grade in 8bit .
Maybe expensive but you can try Sapphire Genarts.Works with afters effects and FCP and Premiere. And yes there is a demo and its pretty fast.
Austinv ,
Premiere doesn't suck and rendering in After fx is not stupid.
It does what you tell it to.
