Yeah, Vimeo is quirky. It often takes much longer to load and play on my mobile devices, so I use it only when the video isn't available anywhere else.

The YouTube version appeared a bit better about 12-24 hours after uploading, so perhaps it takes awhile before the HD version shows. Comparing the two now, the Vimeo version is only slightly better -- mostly more contrasty with slightly more saturated reds in the lights.
