Are there any UNGRADED CinemaDNG samples with audio? Samples covering motion and skin tone? CU and wide shots?

I don't think it's the sensor itself, which, if it's the BAE/Fairchild CIS2051, can run up to 100 fps at 2,560 x 2,160 and 200 fps at 1,920 x 1,080. Like the Scarlet and Epic, the BMC may have a maximum overall data rate it can run at (as determined by an number of its components, like the SSD controller). If that's the case, it could conceivably run at a higher frame rate if the per-frame data burden is reduced via a compressed codec like ProRes or (my suggestion) CineForm RAW.

Or, it's our old friend HEAT!

I posted an answer that was partially wrong.

While the ProRes and DNxHD outputs are not log -- as I said. They are pulled from a master log curve from the 12-bit sensor.

Therefore, I think the RAW data is output as log.

My question for BM -- the camera can apply REC709 gamma to an area of the 12-stop log curve. Why not simply deBayer the whole log curve. Now output this at 10-bit log C in PR 422 HQ or DNxHD 422 -- or 12-bit ProRes 4444.

I'll bet Resolve will handle these files and Glue makes importers for log C data.


I've been working with RAW for 2 months. It is a royal pain in the butt! The only things neat are:

1) set the WB -- AFTER THE SHOOT.

2) in AE create, an lazy-S gamma curve or black stretch or expand -- AFTER THE SHOOT.

3) A way to get 12-stops of DR.

When you consider than some RAW software takes a MINUTE PER FRAME to process -- you can see why just getting the 12 stop DR -- FAST -- is all I really need.

And, yes, each scene as usually will need to be CC to 0% to 100%/108%. But, with Media Compose and the new Curves plug-in for FCP X -- that's not going to be a killer job. And it's real-tme unlike RAW1

Re: New! Blackmagic 2.5K Raw cinema camera!
 
It's been almost 2 months to the day of the announcement at NAB. We saw the original specs, the original footage, but now it has gone silent. With the release date drawing near, why are we not hearing anything new? I have mine pre-ordered but I need to hear the final specs to feel 100% sure that it meets my needs. I do a very large amount of handheld work, and with my 7D i rely on the IS of the 17-55 lens to smooth out the "microshakes" that DSLRs exhibit when not on a tripod or without IS. I need to know if IS is indeed supported on Canon EF lenses or not. It has not been stated clearly at this point.

Anyone with an insight on any of this?

Marty, the final specs have all been announced. The details are all up there on BMD's website, and it's been reported ad nauseam by BMD reps every time they've been asked these questions - they're going to deliver the specs they announced, and nothing more (at this stage).

So no IS at this stage, no AF at this stage, only 3 ISO settings and the mount will be EF.

Re: New! Blackmagic 2.5K Raw cinema camera!
 
I have read through the specs "ad nauseum" myself and see no official reference to "not supporting IS" anywhere in the official literature. I have read speculation, reports from people at BMD events contradicting each other and reports from John Brawley (only one to actual shoot with this camera that we are aware of) saying they might add additional ISO before release.

Regardless, I'm just looking for any new information about the camera and possibly some new footage. With the release drawing near there is a lack of any additional information or reports and that is just a little concerning, especially when other cameras that are due to ship around the same time are getting full reviews on higly respected websites.

Kind of strange; here we are sitting at July 7 with projected camera shipping "towards later part of July" and not a peep about any new info since April. No sample footage since April, no nothing.

it isn't that strange. I'm waiting on several product releases since NAB....

waiting is the new normal.

Scarlet deja vu... all over again?

What about the EOS 1DX? This was announced last November & is still not available.

Really? I haven't seen any reviews of a production model & it's only available to pre-order from every Canon dealer that I can find.

Some new raw & graded stills from John Brawley here. Looking pretty good:

Thanks for that Simon. If this shows what the camera can do, it is very exciting.

That said, I am not sure about anyone else, but here we are with less than a week to go and this is the first taste of anything that I've heard concerning the BMD. Doesn't it seem weird not to have at least
a little bit of marketing by BMD, or an announcement saying that it will be postponed? Something?!

I am sure BMD is working day and night to be ready, but to hear nothing, other than rumors
of 200 being delivered on time - or the other rumor that their vendors also being left in the black as to what the magic design is (not good). I would prefer to be told *well ahead of time*, "Sorry, it will be delayed." It has to do with cred.

And yes, I get it. This cam, with all the features has great *potential*, but if BMD whiffs
on this one, it will only add to their reputation of being - how does one say it delicately,
falling short of what is being promoted - which speaks to other aspects of dealing with them.

I do think that BMD moved the camera world at NAB, and I am thankful, but for me even if they
deliver 200 cameras, though wonderful, just means that something else (the execution of the plan?) is still not in place - and possibly half-baked.
