Magic Lantern enables 14-bit RAW CinemaDNG on 5D

Only speculation, but I've been in that market: apart from the fact that it just looks like the CMV12000, there's no other alternative with similar specs! Unless it is a custom part (I doubt it, but it could be), it has to be the cmv12000.

Why couldn't it be a Sony/Panasonic/Canon/Whatever sensor? Or some other company that the mainstream doesn't know about?

I mean, the BMCC was purported to have an sCMOS sensor made by BAE Systems, which a lot of people haven't heard about, or didn't know they made imaging sensors. But there was never any actual proof.

I have a hard time believing that BMD would use what is essentially an industrial camera sensor. It might be a CMOSIS sensor, but it might not be one of their off the shelf designs. It could be a custom design, CMOSIS as you know does do custom sensors, and it starts at around $750,000.

It could even be a case of using a pre-existing design of the CMV12000 and altering it such that it has better DR, but loses some other features, they have the capability. Leica used CMOSIS for a custom sensor in Sept of last year, so I don't see why BMD wouldn't.

But the raw2dng.exe doesn't work on files over 4gb in Windows, right? So current Windows users are still limited to 48 seconds raw even with a 1000x card formatted as exfat?

At this point only the linux raw2dng converts 4Gb+ files, windows 4Gb, osx 2Gb. It's only a matter of time.
 
I just hooked a Lexar expressCard CF reader up to my macbook with an internal samsung extreme SSD. It's recording a 4Gb file from a Toshiba 1066x card to the SSD in 28 seconds. That's roughly 142.8MB/s. A CF slot to external SSD option looks feasible and should make 720p 60p doable.

Squig,

Since you have the toshiba, do you think a faster card than a 1000x could still squeeze out a better performance out of the mkII? Like a sustained 1880x 1080, or 1880 x 960 ?

I'm not sure the Toshiba is any faster than the 1000x Lexar, the Lexar is a couple of MB/s faster in the benchmark tests. I submitted some new test data for A1ex to have a look at, I should have the results soon.
 
Ok, I ordered the Lexar, should be in tomorrow or day after. I think it's the most consistent and reliable of the bunch right?

Yeah the Lexar and the Toshiba are the top dogs for now, they seem to be maxing out at 98 and 96 MB/s. I suspect the Delkin 1050x comes off the same production line as the Lexar, the benchmarks are almost identical. All rest are slower and the komputer bay are a great option if you want to be murdered by your cast, crew, clients, financiers etc...
 
On the audio side, have you done some test syncing with the mkIII? I hope the sync offset in my test will be improved by a fast card.

About crop/magnify mode, is there a way to have an accurate preview of whats being recorded since its recording off center?

This would be a much more viable option. Pretty easy to buy a second door for the 5D as well.
The thing is, the cost of 4 Lexar cards is already more expensive than a Ninja with SSD solution today.
So yes, someone needs to make a CF adapter.
However, by the time that rolls around BM will probably have invented an IMAX solution with universal mount and doggy doo doo scooper.
In fact now that I think of it, they themselves should come up with the adapter!

I don't think it's a Sony/Panasonic/Canon sensor, because those manufacturers don't usually talk to you unless you put down a lot of cash and sign a contract saying you'll buy A LOT of sensors. I don't know how many cameras BlackMagic has sold so far, or how many they plan to sell for their 4K variant, but development takes time, and I don't think these manufacturers would have listened to BM one year ago.
Same for the custom part: it usually takes at least a year or two to create one of those, and I doubt BM would have gone that route even before bringing the original BM to market. Too risky.
This is all my own speculation, though. We'll know soon enough.

They're rebranded lexar cards that didn't pass QC. I wouldn't trust them with a 10ft pole is what I mean. The last thing I want to be worrying about on set is whether or not my cheap and nasty CF card is gonna crap out on me. I'ts like driving in the snow with bald tyres, you just don't do it.

Zee Germans are working it, they'll probably have it up and running in a few days, they're German. Yeah cheap fast reliable big, sounds good to me. You can still go light and stealthy when need be too.

I just tested the squashed 540 -840p mode, it looks like crap, not sure what's going on there. 720p looks good but the cards are a bit too slow for 720p 60p.

Ted I haven't even touched the audio side of things yet, not a major concern for me but I'll look into it in the coming days.

Logged in this morning, and there's a new raw2dng.exe that works in Windows for files over 4GB. Time to reformat the 1000x card for exFAT and get crackin' :)

Now this is an interesting post. But you'd show up on set with a hacked MKIII that clearly will lock up and get hot during recordings? One that VERY often requires the battery to be ejected and reinserted? C'mon - the 64 GB Komputercards are fine and will do 1920x1080 - I'd trust them over the hack in its current form. Geesh.
 
Has anybody even reported a 5D3+RAW that got hot and/or locked up? Because I've read reports of komputerbay cards going puff...

I wouldn't hesitate to use ML in a serious project (in fact, I can't even conceive shooting with a Canon DSLR without ML), but I wouldn't shoot it on cards I don't trust. (I'm still unsure if komputerbay cards fall in that category, but it's not looking good for them)

this is not what the Komputerbay guy said at all. somehow this has been morphed into this from my original post. What he said was the cards are made from the exact same components with a 20 percent vairance on QC. Meaning they are made with the same parts just with a 20 percent less effective QC at komputerbay palnt vs lexar. He never said that these were cards that failed QC at Lexar. Same exact cards just made by people who have a 20 percent higher chance of dropping the ball.
