That is incorrect. The Viper is a video camera. It does not produce
RAW files, it produces dual link RGB HD video. The names "film
stream" and the like refer to the format of that video, with the
values either encoded to a log format (film stream) or gamma
corrected and white balanced (the various monitoring modes, as well
as some other available feeds). There is gamma correction in the
non-"stream" feeds. There is no need for demosaicing because there is
no mode that produces RAW files.
The only current digital motion picture camera that produces RAW
files that I know of is the Dalsa. It is also promised in the Kinetta
(if and when it arrives), and potentially in the Arri D20.
