Hello,
since de-bayering as a form of image-resampling is 50% science and 50% art,
there is
simply no guarantee that two de-bayeres from two companies
could deliver exact the same result.
Think of video-scaling in different NLEs. All of them are producing worse results,
because all are using bicubic resampling algorithm, but also non of them delivers
exact the same image as the others!
RED can guarantee consistency in de-bayering (thought they release updates on that regularly),
because they offer a SDK. So there is always only ONE right way to de-bayer RED-footage
at a given time.
To stress the argument that CinemaDNG is an open format would be
a wrong comparison in this regard. It's as open, as 4:2:2 is 'open' or
a resolution of 1920x1080 pixel is 'open'. It's an open container format.
What is done with the information to calculate an image from the information
saved in this open container, depends on a company competence in image resampling.
Given the worse video-scalings inside major NLE's, I won't expect anything good from them...
That's the bitter truth.
Nevertheless I've faith in BMD to deliver the very best de-bayering based on their Teranex-algorithms.
A SDK would be nice to have a kind of standard for BMCC de-bayering.
This could guarantee consistent results.
Hope it helps.
Best regards,
Bernhard
