Just tried out Dark Energy and decide to buy it. Great plugin for rendering at low samples a nd then denoising in After Effects. Lower sample times means faster rendering! Check it out they have a trial version. Great for removing noise forum animations. I did check Neat Video as some has mentioned on the forum but but Dark Energy is more advanced in my opinion.
Especially built for GPU acccelration!
