really wanna know what software you're using, would also like to hear what you did to workflow (timeline, then grade; or vice versa?). If they were to integrate LR4 with premiere I would never go back to FCP.
haha that's like asking if Photoshop allows you to adjust colors.
AE is better than Color in some respects, and inferior in others. I like how Color has better luma processing, but I hate the node-based workflow. AE has better motion tracking too, which is another plus. And if you are planning on doing any sort of VFX, AE is the natural choice since you can do both in the same program.
