Magic lantern... Dude.

Hmm, not to shabby. Still issues but great for people that has one of these cameras. I wonder is the studdering from the camera or from the upload? Then the compression is har to jude since it's on vimeo would be great to see a tif sequence or such.

and the comparisons also start to pop up...

 

[Jens Rosengren]

Wow, starting to look impressive.
Those guys are actually amazing! The interface might not be amazing, open source projects can sometimes end up that way, but damn, they're talented!
For a second I actually considered buying a 5D MIII before a Scarlet. Silly boy..

 

[william howell]

I want, and need 96fps... Heck.... I need 300fps..

There is no comparison in my mind to any of the red cameras..

But... To have my dslr shoot this quality footage is awesome... I've been smiling for 3 days now...

 

[paulherrin]

definitely much improved images coming out - wonder how hdmi-out will compare? does anybody know whether rolling shutter is worse (i.e. slower read/reset) or the same?

 

[Wayne Morellini]

It is a shame they can't do this for the gh2 and 3. The hacks get a lot of attention, but stuff like this is where it is at.

 

[Lee Saxon]

It's interesting that "raw" is 1920 x 1080, not the full 5.6K resolution of the sensor, I guess this means that the line skipping / pixel binning / whatever is done in raw from 5.6K to 1080P before conversion to RGB, which makes sense.

I think the debayer, even more than saving to CF cards, would be the bottleneck of shooting full resolution on one of these cameras, so it makes sense that it would be set up as you say so that video mode only has to debayer the 2K.

 

[Alan Hadgis]

Wow those ML guys are crazy smart :-O Props for all the hard work they are putting in! Pretty much pre-alpha code too, just wow.

 

[Robert Ruffo New]

if i'm not mistaken this is a series of actual frames, just like if you held down the trigger. i.e. not regular video mode, so there's an internal scaling that's going on, like when you set it to a resolution other than the highest. they're just doing that because of internal processing speeds and the media itself. isn't there supposed to be a clean hdmi out or something though? that may be closer to what you're thinking of.

No internal scaling in real time would be possible with those ASICs

 

[Robert Ruffo New]

Not at all.

The component Peter overlooks is that size of focal plane is a huge factor of the perception of relative DOF.

The area which is measurable in focus at a given focal length at a given aperture is identical, but as the focal plane changes, the relative DOF is higher (more of the resulting image is in focvus) if you frame the same shot with a wider lense or pull back to get the same FOV with an identical lens, at the same aparture.

Makes sense?

That's not the whole story - f-stop is fractional to lens focal length so f2 on a 100mm lens is actually a bigger physical hole than f2 on a 16mm lens.

Continuous RAW recording out of Canon 5D MkIII
http://www.eoshd.com/content/10324/big-news-hands-on-with-continuous-raw-recording-on-canon-5d-mark

Lead in to the article:

"I have no other words to describe it – this is huge news.

Magic Lantern have done the seemingly impossible and given us a continuous raw recording mode on the Canon 5D Mark III. Once activated in the menus the 5D Mark III becomes essentially a full frame Blackmagic Cinema Camera and amazingly mine has not yet exploded. No more short bursts of raw, this is the real thing.

The image is leaps and bounds ahead of any other DSLR. We’re talking Alexa / Red league here, yet full frame. The first ever raw video shooting full frame camera at that. I’m getting continuous recording at a data rate to the card of 90MB/s and the camera hardly breaks into a sweat."

But they are short bursts because no one has exceeded the 4Gig file limit yet with this. Which means no one has run this for more than a minute at a time yet - there is no telling what heat effect say a 4 minute take would have, or what long term damage pushing the asics that hard that long will have.

The 4GB is a Fat32 limit. It will be spanned without too much issue at a later date.
It is much more processor intensive to transcode in camera than to carry a stream of raw data, so I am not sure we have to worry too much about either of those.

 

[David Mullen ASC]

So any confirmation as to whether the different resolutions in raw involve cropping the sensor down?

Is it possible to send this raw signal through the HDMI-out or can it only go to the CF cards?

 

[Samir Patel]

Would be interesting if we can crop to s35 size but output the 1920x1080. I would love to have option to do custom crop so I don't have to carry my scarlet everywhere. I could just shoot my tests on 5D

 

[Stephen Pruitt]

This is pretty impressive work, and for a whole lot less money than a Scarlet.

I suspect that whoosh you all heard was the Scarlet program heading into the sunset.

Interesting times, gentlemen. Interesting times, indeed.

David,

Other than 1920x1080 and 1280x720 (as well vertical 1280), 1:1 crop is also possible @1080 and @720 beyond to be format agnostic too.

Up to 3.5K (but buffer can't handle more than a couple of seconds with drop frames).

So far, only on CF cards.

I'm at a gig right now, so I can't search for it... But someone on the magic lantern forum was exceeding the 4 gig file limits earlier today.

At least he was reporting that.

 

[Steve Das]

It is just an internal RAW dump to CF. There are issues getting clean HDMI-out signal.

The initial idea was to use HDMI out to bring the 14-bit monochrome signal to an external recorder that can do uncompressed video. For that, they would have to disguise the 14 bits of RAW to make it look like 422 8-bit video. Not easy but not impossible... but then they found that Canon's HDMI-out messes with the image, applying chroma averaging filters and nasty things like that. Since nobody knows exactly which math Canon is applying, this makes it impossible to recover your original 14-bit information from the altered disguised information. So, right now, it's a dead end.
