I'm with you on the importance of the CCD, but isn't it the whole point of lossless compression to fix your banding problem? I thought banding was because of the information thrown out by h264. When you color grade, you're smearing the darker pixels out over the whole range, and digits that h264 considered insignificant all of a sudden become significant again ...
Banding is fundamentally a problem with Bayer Filter sensors. Bring back prism spectral modulation 3CCD before you are considered cinema quality in my book.
