Amazing stuff. I can think of no other word for it, just amazing. Thanks for the report, Ted!

Your welcome Chris,

I edited my previous post. My frames captured is not 36 frames but 51 frames DNG per burst!
:) I missed setting the end trigger in the burst settings. That's more than 4 seconds in 24fps.

And in order that we can really be objective about the quality of this progress I am currently doing chart tests to see its impact on the charts. I will compare it also with and without a mosaic filter.

It's great to hear of what these Canon cameras can do. They have made significant discoveries trying to enable full uncompressed HDMI. Not only do we have RAW still images from the liveview video stream. They have also managed to get RAW video working on Mark III.

After checking the footage, the 133x cf card I have only does 51 frames consistently on the 5D mk2 using april 30 build. Thats roughly 2+ seconds at 24fps.

I changed my previous posts of 102. I missed the break between 2 51 frame clips as the test I did was locked down and there was no difference. The frame count just continued to the next take.

Now the ML team say they have 400+ frames raw at 720p on the mkIII using a fast card.

For the 5D mk2 the raw dng hack will not improve moire and aliasing. The mosaic filter will still be needed. Maybe the mkIII's softness will be improved.

Res chart I did on the mkII also with and without mosaic filter.

Remember though that this is the early stages and this is just from the nightly builds. For this test I used the April 30 build

This development is going to get exciting in the next couple of days. Hopefully. :)

ML team have now found a way to do continuous raw video recording via lv_rec. Unlike the burst mode.

The last build I used with burst mode already upped the number of raw dng frames recorded from 51 to 57 using my mk2 and a slow cf card.

They are going via a different route instead of burst mode.

The ML developers now can record several seconds of raw video. There is video going around showing a dog at 12 seconds but I won't link it here since I can't personally verify it it.

Ok. I think the GUI is now up for 5DmkIII and here are samples.

A 5d MKIII stops recordng at about three sequential 30minute segments. This will run hotter, so do not expect to record events or docs with this, but for narratives it will be YUBBA DUBBA DOO!

Based on CF read/write speed benchmarking developer a1ex says that the following resolutions are possible on the 5D II at 24fps

- 1880x840 in full-frame mode (with line skipping)
- 1920x840 or 2152x720 in 1:1 crop mode (zero moire)

The 5D III seems to be capable of higher read write speeds and therefore higher resolutions/frame rates. As exciting as all this is I think we should all keep in mind that none of this is really official until we see some high quality cat videos.

Just got the repo/compile for MarkII raw video. My card is currently very slow so doing some familiarity tests for now. Still trying to let it sink in my head to see the words "RAW VIDEO ENABLE" in an old 5D mkII menu. ;)

Shame it's raw as your going to need at least 2.3K to get full HD resolution after the de-bayer. The crop mode might be interesting. Use the MTF B4 adapter to put a 2/3" HD zoom on a 5D MkII and you have a very compact ENG camera.

Very clever reverse engineering that's for sure, but you would still be better off with the BMCC. There are very good reasons why all the current makers of dedicated raw cameras are using faster recording media.

It would be interesting to see if a CF to SSD bridge product could be made sort of like the EF Films products for the EX-1. The card door would be the issue with the 5D as it shuts the camera down when the door is opened.

But, if the door could be replaced with a new door having a window, maybe data flow would not be an issue? This is really early but if the video output is real then I can see all sorts of stuff popping up.

A good test video done by cinema 5d.

Being in alpha stage it still has some minor glitches. Cinema 5D included a shot with one.

Another beautiful one by neumann films:


They even let you download some DNGs to play around with in their site:

Great detail in the footage!

For those with the 5d mkII (2)
 
Since I don't have a fast 1000x CF yet, I coaxed my poor 133x card to capture what it could just so I could get familiar with the workflow and the image.
Here's a video of things around my house, shiny utensils to test for highlight recovery, detailed stuff like flowers, etc. Mostly at 1280x720 upscaled to 1920x1080.
Towards the end are various res chart tests for those interested on the resolution,moire and aliasing as compared to native h.264 and also showing how the Mosaic filter still
is needed even with raw dng recording.
