First Blackmagic 4K footage

That looks pretty darn good. I didn't notice a lot of aliasing which is nice. I would really liked to have seen some faces close up to get a sense of skin tones, but overall it showed killer detail and the highlights seemed pretty good.
 
Highlight handling actually didn't look that good but then again the camera will be cheap, considering. Though I am used to my Sony F3 in log mode so most camera's DR look poor to me now.

Yeah make sure to download the 1080 version at least.

My thoughts as well. Although, even if they had 4K most of us won't be able to view the 4K footage on our non-4K computers anyway :)

We could at least interpolate it down to 2k to see what that looks like. Either way, looks pretty good to me for a global shutter $4000 camera. Hopefully there will eventually be an update that lets it do at least 1080p60, of which there are... rumours.

I agree but someone described it as "killer detail" to which I thought so as well, and then it dawned on me if I was watching it in Vimeo (HD) on a 1080p monitor, it could not present any better than well, just real good Vimeo HD on 1080p monitor. :thumbup:

As an aside, this kind of example reminds me of how good HD actually can be, or that I've grown used to seeing so many low quality HD examples that good HD starts looking like I think 4k should if I had the monitor for it. Ah...you know what I mean.

There seems to be a motion issue though. You can really see it happening in the scene with the people crossing the street and the streetcar in the background. The DR isn't all that great, but hopefully this is just a picture of things to come.
 
for the most part, wouldn't aliasing and moire issues only be noticeable with camera motion? and correct me if i'm wrong but i think that "motion issue" is just a slow shutter speed? and to me the highlights seem to be a little blown in a couple shots there. 4gs is pretty competitive though...
 
For those of you who say the DR is not that great please point that out to me in those clips because I thought it looked great. I've downloaded all of the clips and the only one that would be questionable is the "City Gallery" with the white car way in the background blown out as well as the white umbrella to the right. I think any of the BMC cameras would do that.

Just the clouds really, first 2 scenes you can see the clouds are blown out in some spots, and that umbrella. There were other small insignificant spots too, like in the scene with the tram, there is a white box on the pole which seems to be blown.

However, without the original footage, there is no way to know if it is actually blown, or it just wasn't corrected properly. The DR isn't really an issue for me. It is those motion artifacts which are bothering me.
 
images look very detailed.

the motion did look very strange though,

almost looks like when you leave resampling on in sony vegas

I see. I looked at the clouds in the "Beach Jetty" clip at the upper right hand corner and I can see where you might think that. I still think that looks like what I would expect.

But the "stuttery" motion artifacts...for me I think it has to do with my system trying to play 4K video.

the uploaded video is only 1080p not an actual 4k file

I'm sorry that's not correct. All 8 files are 3840 X 2160.

EDIT: Oh...you're talking about the "edited" footage on Vimeo. I'm talking about the original footage downloaded from BM site.

Actually there are more than 8 of them. I think maybe you should look at the originals because I just watched the clip at the start of this thread and I can see where there are areas that look more blown out than what's on the original.

Down scaled 4k to HD or 2k is the where its at, right now. 4k for 4k release is somewhere in the future.

Also there is something going on with the motion in these shots most noticeable on the girl running @ 44sec in and the next shot of crowd crossing the road. Frame rate conversion issue going Vimeo ?

Still 4k for $4K, hard to beat.
 
I'm really liking the global shutter, the rolling shutter on the regular BMC and BMPC make their image a little 'unstable'. Detail looks superb too, just a shame about the more limited dynamic range - not that it's BAD, just limited. I think the next generation of this cam will be something pretty special if they manage to bring the DR and sensitivity up a bit.
 
And most professionals doing landscape type shots that this might be nice for, would really prefer a wider DR in a good 1080 camera than a more video-ish looking 4k cam. I look forward to testing this thing myself since it would be an ideal companion to something like an F3/F5/C300 for catching wide, detail heavy shots especially in hard to reach spots like where you need to hike in, jibs, aerials, etc.

I still can not believe they handicap it so much but oh well, cheap prices = cheap features.
