How do I record Tekkit Classic Using MSI Afterburner?

[Epicguyof1337]

MSI Afterburner is the only software that can record videos smoothly on my compute. I know it's a FPS Booster/GPU Overclocker, but it also has a intergrated Camera and God-knows-Why. But if you're gonna be mean and point out random stuff that won't answer my question, get out.
