Is that raw from the Canon too?
The shot of the path up to the trees is in this comparison is where the BMCC wasn't as good as the Canon with the raw hack - which has been much improved since this test. And the article also mentions poorer high ISO performance compared to the Canon.
I know when you test these motion cameras, it's much more than just color information, or bit depth, even at times mbps/kbps.
When you look at 444 which is 100% color info, 422 50%, 420 25% you'd think at 420 you'd have a file that would be lifeless, but there is so much more to digital video than just the numbers.
What most of these tests don't show is cameras at their true iso.
I don't know about the black magic (other than the people I work with that have used them on set), or for that matter a hacked 5d2/3, but for the RED 1's, the base iso is 800. Actually the iso is always 800 and all your doing when dropping or raising the iso is pushing or pulling a curve.
Actually with the R1's, pulling it down to 100 is worse than pushing in regards to highlight clipping, (at least in my experience) and now we just set the camera at 800 and leave it, using filters, or light to get to the desired exposure.
It's funny, the Reds shoot 444, the gh3's we use shoot 4:2:0 but under the right conditions you can't tell them apart, even when moving the files in post. Then again, under other conditions the difference is huge.
I'm not an engineer, but I know there is a lot going on under the hood of these things that makes a huge difference, especially combined with different lighting, subject, ambient color, ambient bounce and the big killer, heat.
With the R1's I would leave them on, when shooting stills, or just to avoid the long boot up time and if you then go into a long take, you start building up noise.
The Gh3's will do the same, though not as pronounced and I've been told the original bm 2.5k cameras are also affected by heat.
So comparing these cameras is a difficult task, especially if you just go from the specs, because all of these cameras have a sweet spot. When your on, they are all marvelous, when your off, they can be a mess.
I think Digital Video is where digital still capture was about 10 years ago, with the quality and use all over the place and I assume in a few years with improved and more standard software, graphics cards and better camera design, they will all level off like still capture has.
Not having any inside information, I think the next step is a true combination camera, something like a Canon 1dc 4k and a Panasonic gh3, but both with better sound inputs, maybe even some dedicated coloring/processing suites.
