So yes, essentially it's like working with frames from a Canon DSLR, only at 24fps, and you always have access to the RAW information because it's wrapped in a codec . . . if you had to go through a render application, that RAW information would get "baked" or permanently "developed", and there would be no way to get back to the RAW data controls.
If you want some more information on this whole workflow process, read the powerpoint presentation I gave at NAB this year in the Post Production World conference.

hi jason,
just went through all your slides... very good presentation! i always thought a 3-d lut meant that a color depended on the previous history of that color so, red for example red = f(raw red, time); i guess tha'ts 2d! instead of red = f(raw red, raw green, raw blue). hadn't really thought about it in detail. how embarassing!
