The guy who shot it said no post processing was involved.
From the photographer's blog:
…and that’s with the video that is downsized to 960 x 540 (which is 1/4 of 1080p!) in the Apple H.264 format from the full resolution 1080p RAW footage… the RAW footage that comes out of this camera is STUNNING - so much so that the entire video was cut with the RAW footage - untouched… in any way - no color, noise or exposure adjustment whatsoever…
