I have a relatively big project which is being shot on the BMC. My initial idea was to shoot RAW (DNG), convert the footage to CineForm RAW, and work with that. CineForm gives you 5:1 compression and much faster playback, while retaining good colors and all the flexibility of RAW. The problem is, for this project, we are not settling for anything but the best possible image quality. And, as it turns out, the way to get that is to work directly with the DNG files.

What you'll see below are 200% crops of images processed using different options:
* DNGs loaded directly with Adobe Camera RAW using my "Flaat for the BMC" settings and different values for the sharpness parameter.
* DNGs loaded directly into Resolve, and processed with relatively standard settings (in particular: no sharpness).
* Those same images converted to CineForm RAW using the best quality (FilmScan 2, which gives you approximately 5:1 compression) and different settings for the debayering method.
* Images captured directly on ProRes on the BMC.
They are all final images, graded to taste.
Mouseover on any image to compare with my preferred option: DNG with sharpness=10.

For me, the clear winners would be Adobe Camera RAW and Resolve, which look very similar to each other.

CineForm, even with its best debayering methods, is creating either a much softer image with less detail (Advanced Detail 1), or lots of nasty color-fringe artifacts (Advanced Detail 2). In any case, it is not completely awful either, so consider it as an option if you want a compromise between image quality, processing speed, and storage requirements. It is much better than internal prores, for sure. And having the option to select different debayering methods can be very handy to avoid moire: if you find it on a shot, you can switch to a smoother debayering method (you can also duplicate your footage, use different debayering settings, and mask the troubled areas so they are the only ones using the softer method). For all this, you'll need the $300 CineForm Studio Premium (there's a free trial that lasts 15 days).
The problem with CineForm seems to be in the debayering step, since I've seen footage converted to CineForm RAW and processed with Resolve and it looked just like with the DNGs directly in ACR.

Given how painful working with DNGs is, and given how good Resolve looks, my preferred workflow for projects without lots of VFX would be: shoot DNG, convert to CFRAW, edit in Premiere, export project to Resolve, color correct and render there.
