I DON"T GET IT! I get SOOOO much more noise than this. I don't think I would even use 1600 on a project. But is it just because you compressed it smaller and put it online? Or what? Because I am telling you man this is clean and mine isn't. Can you see noise in the shadows etc? Whenever I tested It was definitely darker than this. Maybe that makes a difference. but I don't really see noise even in your shadows. I get ugly green and red noise. It's not aliasing.
The HD version is absolutely beautiful as well. I had heard stories about how the footage looked & 3200 ISO, so I decided to test it. I was shocked & pleased to say the least.
