The Flatz preset is used for Raw Video. Picture Styles get bypassed when recording Raw.

UPDATED and amazing 70MB/s BUILD available
https://bitbucket.org/GregoryOfManhattan/magic-lantern/downloads/09june13-50D-45e63064ec08-70MB.zip
70-73MB/s  is now possible on the 50D pic.twitter.com/bENSpaArct
shot with this build yesterday and it ran great.

for those "upgrading" from my 28May or 08June builds,
replace your current autoexec.bin and ML/MODULES folder

if you have problems or do not get stable high bitrate recording on fast cards - go through the official 50D checklist (wish it was in the first post of this thread), start over, reformat card in computer, make bootable, reformat card in the camera. put in ML/DATA , ML/CROPMKS, ... if this isn't immediately obvious to you, please refer to the raw video how to  http://www.magiclantern.fm/forum/index.php?topic=5520.0

you should be able to hit stable 70MB/s video on komputerbay 1000x or lexar 1000x

tonight i tried out another workflow and it proved to be a work-slow
.raw from CF card processed by rawmagic 1.0.4 beta into cinema DNGs
opened up clips in davinci resolve - deliver individual clips proress proxy
fcpx - simple linear edit cut down to 60 seconds
export XML
reimport resolve and
... fail (it kept using the wrong clips, examined the XML files had they had the correct clips in them ... maybe some default audio setting in fcpx or ...)

build linked here works at speeds above 70MB/s
so i'm releasing it.

shoot.

What resolution are you getting at 70MB/s?

My 32GB 1000x card worked fine for a while until I got the same problem as you guys. I can write to the card in camera but when I try to read it with my Lexar USB3.0 reader it either doesn't show or is extremely slow.

I believe its a bit over 3x. Could be mistaken. That puts it in the BMPCC territory.

artiswar more like 4 - isn't it?
4572x3168 maximum resolution (wikiepdia)
4752/1920 *1.6 = 3.96

for the 2000 wide (mistake) it would be 3.6 crop factor

JulianH - i always see magenta in zoom mode no matter what the white balance - unless i do a G/M Shift of between +7 and +10 Green - then it can look correct to my eyes

Thanks guys.

@JulianH - I've got 6 buffer stars with Global Draw enabled just for the raw histogram. Enabling movie mode doesn't seem to affect anything in so far as frame amounts etc but it looks like it's cured the pink screen in 5x crop (WB must be set correctly or it does get a bit pink so it seems to act as a good warning to set it) and (of course) exposure now seems to work correctly.. all of a sudden the colors just sing!

For the LV problem try playing around with display settings - Display > Advanced Settings (might help if you haven't already been there).


Loving this 2k Cinemascope. I seem to be getting about 10-15% more frames than the setting suggests and hitting about 62MB/s write speed. Maybe it's card related, I dunno but I seem to have golden settings ATM.  8)

Do you know what the equivalent cropfactor is in 2000x750 5x mode?

Apefos.  Could you be so kind as to upload a source image (dng please),  and a image that you have upsized and sharpend?

Would be nice to see this actually.

I just ordered a Komputerbay 32GB 1000x card. Will update with benchmarks with my 50D once it arrives (should be within a week).

Is there no test with Komputerbay 32GB 1000X?

Interested in this as well.

Don't forget to contribute to the payment of the camera JulianH purchased for 1%. He's stuck his neck out for us and any contribution is welcomed.

Send him a PM to get more details.

Is the Lexar 1000x overkill for the 50D? I'm thinking about getting the Komputerbay 32GB/64GB card but unsure about the cards not functioning after a while.

50D (46K clicks)
BG-E2 grip + AA battery tray
1x original battery
1x fake battery
All cables/charger included.
4GB mem card (not so fast but better than nothing)

Just picked this kit up for 350 euro's. My plan is to send this to 1% - Shipping will be 24,30 euro's or 34,30 (if over 2 kg).

I will try to set up a paypal donation page so people who want to donate can pay me back.
Total about $485 - I'll donate the first $50 so about $435 would be welcome... I will send the camera ASAP (before taking donations) and take the financial risk.

Before proceeding I'll go over the details with 1%. If it doesn't work out, no problem, then I have a back-up 50D ;)

Great initiative Julian! I will be contributing to the donations as well.

For those who want to do some comparisons on their own: Keep in mind that you have to change the focal length to get comparable results! Because the crop factor increases with these resolutions above. They are only crops of the sensor. Here are the crop factors you'll get with the raw resolutions:

Width | Cropfactor | Multiple of H.264 crop

1734 = 1.60 | 1
1280 = 2.17 | 1.36
960 = 2.89 | 1.81
720 = 3.85 | 2.41

So if you shoot a video in 1920 X 1080 H.264 at 55mm and you want to compare it with a 960 X 540 raw video you have to change the focal length to 30mm (55 / 1.81 = 30). At least if my math is correct  ;D


Is this for recording raw in 1080p mode? Does the cropfactor change when you use the 480p videomode to record raw?

550d edmac stubs for raw_rec have been committed to the git. Shouldn't be long now, right wolf?

This is an overprocessed image, but I wanted to test it from Andrew Reid's 600D raw samples.
It's a 960x480, 240dpi resolution image. And when upscaled to 1920 horizontal resolution, it almost totally emulates the clarity of super 16 film!


In what way did you process this?
#16
Even though it might seem futile to developers, 960x500 raw 14bit video would be better than the 1080p h264 default video we get from Canon. My guess is that the raw video upscaled 1.33x to 720p or 2x to 1080p would hold up pretty well, and the extra color information would make the images a lot more clean and pleasing than the h264 counterpart.

Hi

Here's what I'm getting with my EOS 600D and a SD-card that reaches the 21 MB/s limit at 24p:

- 1280 X 720 | stops after  71 frames
- 1280 X 400 | over 1500 frames
- 720 X 720 | over 1500 frames
- 960 X 540 | over 1500 frames

Since the 600D is very similar to the 60D I'm sure that you will get almost the same results. But don't worry, even 960 X 540 RAW videos have way more detail then the default 1080 X 1920 H.264. And of course, working with them is amazing. The dynamic range is just insane!
Getting overexposure with that raw videos seems to bee impossible :D

Would be great if you could shoot a chart or a detailed scene of some sort with both 960 x 540 RAW and the default 1080p h.264 so we can see the difference between them. I'm on a 550D atm, and my fingers are itching for some raw footage.

Whats the easiest way to try this out on a 550D? Replace the autoexec_bin file on my card is a given, but what other files (modules etc) do I need?

Hi Andy600,

can you record 1280x400 on the 600D with no dropped frames? I've got a SanDisk Extreme Pro 95MB/s card and I drop a few frames at that resolution. Thanks,

Matt

If I've understood it correctly, the card speed doesn't matter as the XXXD cameras have a maximum SD-interface speed of ~21Mb/s.

I'm using a SanDisk Extreme Pro 95MB/s 16GB card on my 600D (T3i). When shooting 960x540 raw I get a few dropped frames but not bad. I shot a comparison test of a scene with 1. Normal Canon 1080p h.264 quicktime movie settings and then 2. Magic Lantern cropped sensor 960x540 raw. I used raw2dng on Mac and then After Effects to process the dng files for the 960x540 and exported a ProResHQ movie.

There is currently too much tearing and blocking of magenta blocks for the raw footage to be usable, but the detail in the frames that don't have the tearing is an incredible improvement over the h.264 quicktime movie. Even when I blow up the 960x540 ProRes to 1920x1080 and compare it with the standard Canon 1920x1080 h.264 file the footage shot 960x540 raw blows the h.264 away in terms of detail and dynamic range. Love it.

I'm definitely looking to get a 5D mark iii now, but if the tearing and blocking can be fixed on the 600D it is a huge improvement to what it currently shoots in h.264, even when shooting 960x540 raw. Fantastic job by the ML team!

Can you post the ProRes sample on mega?

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 :)

Can someone post samples from these resolutions from a 600D? I want to try to compare it upscaled against the H264 equivalents.

I'm really impressed with all of this progress.  Great job guys.
I don't really expect this to work with my trusty old 550D, although you've all surprised us more than once.
Time to scour the market for a 5DM2.
