First Magic Lantern RAW Video from the Canon T3i/600D!

Vimeo user Luis Roberto dos Santos just posted this short clip from his Canon 600D, modified with a "pre-alpha" version of the Magic Lantern RAW firmware .

The clip was recorded to a slow card - so there is some flickering and macro blocking - but it blows standard fuzzy Canon .H264 compression away:

If Magic Lantern is successful at stabilizing the code, this will be huge - possibly bigger than the news that the $2900 5D Mark III had been modified to shoot RAW video.

RAW video from a $549 still/video camera body? I'll say it again - these are great times to be a filmmaker!

The only thing preventing the 600D/t3i to shoot 1920x1080 24p RAW is the SD card speed. There aren't cards fast enough to handle all the data. I hope they can find a way around this but it won't be easy.

Interesting. What speeds would be necessary if the high-end Extreme Pro type cards can't handle it?

I don't know but 22 Mb/s seems to be the maximum and it's not enough...

From the forums:
"@Rush posted earlier in this thread regarding best settings for the 600d. Here's what he wrote:

The best you can with 600D (550D/60D) is: (limited by hardware SD transfer rates)
- 960х540, upscale it to 1280х720 (24 fps max)
- 1280х400, tight aspect 3.20:1 (24 fps max)
In Canon's 720p - lineskipping 1.66х, so you should upscale to restore correct ratio:
- 1280x400 upscales to 1280x664 - near to 16:9 (24 fps max)
- 1280x360 upscale to 1280x600 - 2.13:1 aspect
- 1280x320 upscale to 1280x533 - 2.40:1 cinemascope aspect

It is only 1280px wide, but pretty nice looking though :)"

I'm not sure I understand this. Seems the 600D RAW comes from a crop mode and not full sensor.
 
Ok now I understand. The limit is not the SD card but the actual camera recording on the 600D (max 21 Mb/s). So forget what I said on my previous post... here from the forums:

"Quote from: CFP on May 13, 2013, 08:57:40 PM

Could somebody with a fast SD card could give it a try? According to the benchmark my card has a max. write speed of 21 MB/s ... 1280 X 550 would require > 27 MB/s.

check thread - I'd already posted - max possible for 600D/550D/60D is 960x480 or 1320x360.
It is limited not by speed of SD card, but by speed of internal camera SD controller which is limited to 21 MB/s. "

So it seems there will never be full hd on the 600D. Anyway I'd be happy with any of the resolutions available 960x480 or 1320x360 as long as there are no drop frames.
 
I don't understand this card limit.

The hacked GH2 outputs a shitload of data and it also uses SDHC cards.

While the hacked GH2 does in fact output a shitload of data, the hacked canons actually output a metric shit-ton of data. ;)

I believe the GH2 hack tops out somewhere around 180 megabits/second. That's around 22 megabytes/second. The raw output from the canons (at a full 1920x1080) runs about 3 megabytes/frame, or 72 megabytes/second. There are some sd cards that are rated higher than that, but my guess is the limiting factor becomes the card interface in the camera, and in a consumer-level camera there wouldn't be any reason for canon to design it to maintain sustained write speeds that high.
