Is that with auto white balance?

I find it comes out really green looking when I use auto white balance in Lightroom... Have to ramp the Magenta slider right over in some cases.

(The above 'after' images look pretty green to my eyes)

True Roman.  (Lightroom)  ...and I agree.  Cheers!

Also your using the May 28 build right use this build instead it's more stable http://limelinx.com/ca42c Gregory is ironing out all the glitches, so glad that his taking time to work on it.
This is the 23-05 build you are linking. Why?
I've been using 28-05 by GregoryOfManhattan and it is definitely the best so far. More options, better speeds. I don't have stability issues.

I'd strongly suggest this one. Download here: http://www.magiclantern.fm/forum/index.php?topic=5586.msg43359#msg43359

I'm still working on the basic install/settings video guide. Hope to finish it today.

I wanted to see how the 14-Bit Raw stacked up against the native Canon h264 video codec on the 50d.

The difference is NIGHT AND DAY.

35mm f1.4L
Resolution: 1280x720 h.264 vs. 1280x720 14Bit Raw
14Bit Raw converted to ProRes 422
Upscaled to 1080p for optimal viewing on YouTube.

Cool vid, really shows the difference in both sharpness but especially the colors/dynamics. A bit offtopic: does one know what's the best upscaling to 1080p method?

I still need help over those cf cards. Komputerbay 128gb 1000x vs. 64gb 600x vs Kingston 32gb 1000x. What should I get?

the komputerbay cards have a nice performance / price. I heard the 128gb one is slower then the 64gb. (I own one). Try one 64gb first and then buy another one if you need the space

It's trial and error. 600x should be enough, as my Sandisk 90MB/s (600x) is getting the max speed of the 50D (right now, maybe the future will bring more?). 64GB 1000x will be safe. 128GB 600x should be enough, but we don't know for sure until someone actually tries... so go ahead ;)

There is a thread regarding CF cards for RAW recording here http://www.magiclantern.fm/forum/index.php?topic=5391.0
Loads of info on many cards there. Not camera specific, but still lots to get stuck into in terms of speeds / reliability.

Been using ML on 7D for awhile. Love it. Currently waiting on 50D.  ;D Going to need some faster cards myself but Amazon won't ship KomputerBay 64GB 1000x Card to New Zealand.  :'(    Currently talking with them to see if I can get that changed.

-Off topic for here...but anyone got any idea about where 7D RAW? All I've found is "7D has dual processors so its development will be different.  Not working right now." UPDATE: Just found this re 7D :
its not that easy.
the slave processor ML runs on, doesnt have access to the raw data stream as it seems :(
   

@ JulianH let us know when Paypal is set up for 50D body donations.

THANKS TO EVERYONE FOR MAKING ALL THIS HAPPEN. Feel like a kid before Christmas waiting for the 50D in the mail.

Thanks @goldenchild9to5 - I used the steps that you suggested (reformatting the card, backing to a build before 5/28, etc). 
That changed things for the better -- now 1280x720 starts off great, just one star in the buffer, maybe 2....runs for 10-20 seconds, and then just announces 'stopped automagically'    It's not even close to skipping frames - so I'm sure it's another newbie blind spot on my part.
I'll poke around to learn more about that - but at least the chance for some stable 1280x720 raw shooting is getting closer.
Thanks again for the help - I'll watch for any more tips.

Best

Since ML isn't taking donations, I have taken the initiative to buy a 50D + Battery grip + batteries + 4GB CF for a good price. I've shipped it to 1% today.

I hope we can split the costs. If you want to contribute send me a PM and I'll give you the details. Thanks in advance :)

Managed to trade my old 5D for the 50D and cash :)

I got raw recording working. Did a benchmark of Sandisk Extreme Pro 32GB 95MB/s in live view, but it doesn't seem to close the benchmark properly. I can't seem to find a log of bmp of the results. Where should it be?

Maximum seems to be around 50MB/s for continuous recording (with my card).

My results (how can I determine exactly at which frame skipping starts?):
Shot at 24 fps (didn't find a setting for 23.975..)

1592x1062 - frame skipping after about 50 frames (67.7MB/s)
1592x840 - frame skipping after about 480 frames (53.5MB/s)
1592x720 - no frame skipping (44.3MB/s)

1320x1062 - frame skipping after about 300 frames (56.1MB/s)
1320x960 - frame skipping after about 1200 frames (50.7MB/s)
1320x840 - no frame skipping (44.3MB/s)

1280x1062 - frame skipping after about 250 frames (54.4 MB/s)
1280x960 - no frame skipping (49.2MB/s)


-Waiting for 50D in the post- looking at card options. Just looking at these speeds against the benchmark of my current cards, Sandisk Extreme 60Mb/s - 8/16/32GB. The 16 and 32 GB write at 44.5 Mb/s.  Lowest speed from Julian is 44.3 MB/s at 1320 x 840.  I'm thinking / hoping to be able to record something like 1280 x 720 on these cards just to get me going. Still crossing fingers Komputer Bay get back to me about shipping to NZ  to make the most of this amazing breakthrough.

Has anyone had any success with 60MB/s cards and lower resolutions? Or should I try and find bigger and faster card (that ships to NZ)  ASAP???

Advertised speeds are maximum read speeds. Write speeds are typically lower.

Just benchmarked my cards with CrystalDiskMark in the USB 3 card reader:

Sandisk 32GB 90MB/s CF: 96MB/s read - 66MB/s write
Sandisk 4GB 30MB/s CF: 29MB/s read - 24MB/s write

The write speed is the important one!

My sandisk extreme 60MB/s seem to be writing at 44.5 MB/s for both 16GB and 32BG. 8BG was 40.9.  Hope this gets me some RAW footage to play with. Even if its 1280 x 720 I'd be happy!

which reader are you using? I tried one from Transcend on my Mac running OSX 10.7.5 but the DOS file system could not be mounted. ExFAT worked on the Mac but not on the 50D.

In one of your post you said not to use the May 28th build guess I was reading wrong than, Gonna try out the new build today.  For some reason I'm getting a lot noise in almost all ISO settings don't know what I'm doing wrong.  Is it a setting that's boosting the noise in camera.

Just a basic HAMA USB 3.0 reader. On Windows, don't know how that works for MAC. Should be no problem, card reader = card reader... it's just usb... as far as I know.

My sandisk extreme 60MB/s seem to be writing at 44.5 MB/s for both 16GB and 32BG. 8BG was 40.9.  Hope this gets me some RAW footage to play with. Even if its 1280 x 720 I'd be happy!
1280x720p should be safe!

@Goldenchild: what mode are you shooting at? M? What lenses? (manual aperture?) what iso's? upload some DNG's! just send them to yourself with www.wetransfer.com and paste the download link here.

Great to hear.. Gonna try the new build & see what results I get than I'll send you all my steps using the KomputerBay 64GB card.  Also one more thing I think you should try to reinstall Canon's 1.0.9 firmware on your camera to give it a fresh start, than put all settings to default there is a button for that.  Download here: http://limelinx.com/ds6cw

Thanks for reply julian I'm shooting in "M" mode, using a manual Nikon 50mm f1.8.  Tried ISO's 100 - 800 all seem to have noise.  Gonna send you over some DNG's ASAP.

Check your histogram, if you underexpose noise shows up earlier. If you start lifting the shadows it will get more obvious of course.

I'd recommend you benchmark in camera . . .

Agree. Although the benchmark in the camera doesn't seem to end correctly (for me) and doesn't save the results.

Also, in live view, the benchmark is not showing the max of your card, the card controller can be the limiting factor. So it can be interesting to check with a USB 3 reader what the card is capable of, I think.
