Magic Lantern enables 14-bit RAW CinemaDNG on 5D

Somebody correct me if I'm wrong but it's my understand the MK2 doesn't read ex-fat formatted cards so there's a 4Gb file size limit and the cards appear to be writing a bit slower on the MK2. Resolution wise it's about the same except the aliasing and moire is pretty bad. Development is happening on the APS-C Canons but the SD card speed is a limiting factor.

Go and watch most TV commercials. Usually shots last about 2 or 3 seconds. This RAW hack has made the MK3 a potential player for high end budget commercials.

High end commercials shot from the tripod, really steady style, nothing handheld, no subjective camera, no Lars von Trier, no Inarritu, (Diego Prieta), no Bourne trilogy, the list can go on and on, comparing commercial to cinema, cinematic style. Lots of commercials shot with active camera these days.

Rolling shutter still there no matter it's raw, some say it's more artifacting the image. That what stops me, thinking should I get a 5dmk3, in Russia it about 3 K$, less than the US price, which is good, while c100 is about 25% more than the US price!)

Still wait to make me spend 3K, have not yet seen a solid grade from 5Dmk3, something commercial good, not a birthday, wedding or artsy vimeo good, which are totally different things.

For many reasons I appreciate my C100 even more so, much less rolling shutter, (I shoot photos commercially as well, with Nikons D4, D800e, which are best cameras, period, IMHO, the quality of Raw, is different on Canon than Nikon, to the benefit of latter, can pull more shadow detail, much by about 4 stops, to get the same amount of noise comparable to Canon raw noise. That is another subject, the quality of RAW, "Not every Raw bourn equal", paraphrasing famous quote..
D800e video grades well, to go along with C100, in my experience, almost impossible to grade it with H264 5dmk3, which before ML raw, was probably the softest HD DSLR in the history.

While appreciating the color, possibility to grade it in ACR, Lighroom, main thing is horrendous rolling shutter, that is going to stop a lot of producers, considering to get DSLR, for anything but tripod..to shoot RAW, unless they have a huge budget to fight artifacts in post production, spending much more $$, than renting Alexa in the first place.

Non scientific response, but my gut says the 5d3 rolling shutter is better in raw mode. The camera motion just feels different.

I think rolling shutter is exactly the same as in the old H.264 video mode, if you record the same resolution (because the RAW buffer that's being captured by ML is created whenever liveview is on).
If so, it's slower than that from a C100, but not by much. And it's faster than a BMC, for example.

I'll do the rolling shutter test tomorrow, I think it's the same but the cadence might be better.

A good find about rolling shutter figures, in real shooting I see significantly less of it in C100, than any DSLR..
IS lenses help to fight rolling shutter, EF 17-55 2.8 IS for example.

If it follows the DCF standard, like it should, I believe it would support exFAT. It may not natively format that way in camera, but it should be able to read/write to it. Not totally sure though, but there is only 1 way to find out!

I think that's also related to camera size and weight: DSLRs are easier to mistreat!

Which is why the only actual candidate as competition for the 5DMIII is the BMC production camera. Global shutter means more to me than the 4K even. That said we will see where it is at with moire and aliasing...

The C100 reads its sensor at 60fps (1/60th of a second) when shooting in 24p or 30p mode, and 50 fps readout for 25p. This helps.

It also uses an additional high speed readout mode for 60i shooting mode equal to 1/120th of a second.

What worries me about the BMC-4K is the DR. I've worked with that sensor. It's and awesome sensor, but it's not designed for cinema cameras. Detail is amazing, but DR is really, really low, and the only way to make it bigger is with the various HDR methods that it offers, all of which will create motion artifacts in the highlights. I think many people will be underwhelmed by the BMC-4K (not because of the camera itself, but because they have set their expectations too high).

1066x CF card is in da house. :2vrolijk_08:

Here's the real world sustained test results with the 18/5 build. I got bored shooting my foot after 9Gb.


1928x1180 24p @ 90MB/s
1440x672 48p @ 77MB/s
1120x640 60p @70MB/s dropped frame @ 2300 frames.

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?

In what sense/way?

I have rented the evaluation system from CMOSIS: a PC with a camlink card, attached to a PCB with the sensor, an FPGA, and a lens mount. I played with it for about a week. I measured DR in standard mode, evaluated sharpness, noise and low-light sensitivity, looked for a way to get accurate colors, etc. And I played a lot with the various HDR modes, to see what I could get (in the end, easily 13 stops, but nearly half of that with fast-shutter artifacts, i.e. my camera would have a lot of headroom in the highlights, but if you place your talent in that brightness range you'll get the Gladiator fast-shutter effect).

I see—interesting.

Is the sensor BMPC confirmed, or only strong speculation based on photos?

I haven't seen anyone from BMD confirm that it's the sensor, so far it's strong speculation but looks to be right. Who knows how they'll tune the sensor, sounds more like it'll be closer to 11 stops, though.
