EDIT 24 Oct 2018: I revised the grade of both videos to facilitate comparison among the raw formats. Images of DNG and BRaw settings now appear at the end of this post.
Amidst the excitement about Blackmagic Raw (a.k.a. "BRaw"), it is hard to find attempts to evaluate the various Raw and BRaw options side by side. Would a thread dedicated to that be useful?
Getting a firm handle on this is probably not simple. The formats will differ in their relative advantages in different shooting conditions, with different subjects, for different purposes (e.g. natural vs. FX pipelines), and towards different delivery formats.
So, in case this is interesting, may I offer this, which shows the same outdoor scene for ten seconds at each [B]Raw option, shot 2k 16:9 windowed at 120fps:
Look at the video description for more technical details.
The same day I also shot this, though clouds passing in front of the sun make it harder to compare [B]Raw settings:
My preliminary impression is that DNG looks nice for these scenes, with BRaw Q0 and BRaw 3:1 in the same league as DNG 3:1 and DNG 4:1. For a lot of work I could shoot BRaw Q5, but I don't see a use for BRaw 5:1, and I'm not crazy about BRaw 8:1 or BRaw 12:1. This impression is very tentative, though.
These scenes were brightly lit. It would be interesting to see low light shooting. And it would be interesting to see how these formats hold up in keying situations such as green screen work.
Here are how the raw settings for DNG and BRay were set for the grading of both these videos.
