The other thing that struck me has nothing to do with the camera as such, but why are these guys so obsessed with shooting in light that can be best described as "challenging"?
I mean really, what can one say, really? I walked away from these videos just shaking my head. I saw the following issues, to name a few:
* Detail that at best was not quite as good as good 1080p. So what's the point of the 4K?
* More examples of color grading that just take your breath away, they're so bad you could lose your lunch. So what's the point in shooting RAW for these people, honestly?
* Example after example of blown skies, a total lack of detail in things like snow (just a white mush) etc. So, what's the point of the extra DR...just to say you shoot with a camera that has x stops of DR? I don't get it, I never will.
The last example was probably the best, not great, but the best of this bad group, IMO. So here we have the subject in front of the windows that are blown out with no detail observed on the other side. This beautifully illustrates the point I've made countless times. I don't blame the editor/shooter here, that's what he should have done, focus on the subject
. Who cares what's on the other side of that window if it's not relevant to the subject? As I've said, you see this countless times in almost Hollywood movies.
So here again, what's the point of shooting RAW or shooting with the extra DR? We could do that OOC with any decent equipment.
I think I'm done watching these BMPCC 4K videos, they're just too depressing to watch. I'm not saying it's the fault of the camera, I don't know, but it just points out the things I said about the 2K BMPCC. Do you really need the extra DR, do you really want to spend time trying to get color from RAW video that at best, may match good quality OOC color on a good traditional camera.
For those that forever argue about 4:2:2 or 4:4:4 vs 'lowly' 4:2:0, there was an interesting discussion on another forum that put this in perspective and highlighted some of the overblown claims about 4:2:2. To put it simply take the following test and see how you do. When you score less than perfect (and many do far less than perfect), keep in mind that this test is nothing more than 7 or 8 bit color represented by the differences from one shade to another. So the point is, if you just score "OK", then you're even having trouble differentiating no more than 8 bit color.
Now yes, if you intend to do a lot of grading, then perhaps you'll benefit from 4:2:2, but if you do what most people do in the editing process, suffice is to say 'not so much'.
