[Konvas] color correction in post (was: first test time lapse ... with 7D)

[Adam Frey]

I'm assuming this is, more-or-less, strictly for high end 4k projection, and not for the average home pc or home theater.

 Most of what has been "published" is math and technical applications of things that don't yet really exist, and are only available to members of the technical groups.

Remember that the idea is to go to something that deals with this on a 600hz "refresh only the changed pixels" reflection system and what might sound like a huge step backward might mean that the tools you are using are the problem-- the reason the image size, refresh, and color standards need to be replaced, the first step being to get rid of the progressive scan and the brightness adjustment within a color.  Because the amount of light being dumped onto the reflectance chip is uniform the RGB methods of determining brightness don't work because they are based on creation of a pixel of light or the transmission of light, which is variable.

CMYK for video/film sounds like a huge regression to me when all the tools in the post world are based on RGB workflows. Is there some document online that discusses this as a serious 4K projection pipeline ? 
 
In terms of timelapse colour correction I now use the Adobe Camera Raw plugin (5.6) to open RAW 5DmkII sequences in After Effects CS4. You get to do a global adjustment on import, then I use a combination of Magic Bullet Looks (avoiding all presets), Colorista and Color Finesse. I create a 1920x1080 32bit float sequence and turn off the project colour correction, which I find inconsistent (or consistently incorrect). I usually render to a prores master on the Mac. Let me know if you need more detail, 
 
Cheers
