I did my first tests with the http://bit.ly/10TBM7a 5dmk2 double buffer from coutts version. I have 90mbit/sec sandisc cards (about 600x). Only with 1880x720/25fps and global draw off can I record without dropped frames. Is the limitation the CF card or the 5dmk2 hardware (buffer?).

Great work folks!

It there a way to write EXIF data to the RAW files? Would be helpful for lens distortion and vignetting correction in LR.

My card's the same brand/speed and my limits are the same, which tops out at approx 55 MB/s. Another user posted a benchmark with a 1000x CF card but it topped out only around 65 MB/s. Overall, I'm not sure what the 5D2 is still capable of and would like to see if anyone else managed to get higher rates somehow.

Is there a way to set the fps besides FPS Override?
Can the shutter speed be set independently or will it be controlled by FPS Override?

Ran some tests on the 600D raw capabilities, definitely not going to get anywhere near the mkiii capabilities unless a miracle happens but 1280x360 is definitely usable and runs continuously, and 1280x480 records a solid 5-6 secs of great footage until frames skip or corrupt.

Going to try and post a video tomorrow. Hmm, may be time to retire the 600D and splurge on a mkiii?

The entire ML team is way ahead of their time, huge thank you to all of 'em. I think you guys just revolutionized the entire cinematography world.

Continuous RAW video on 5D Mark II res 1880x720 without frame skipping (stopped automatically on 3.9 GB), CF SanDisk 16gb Extreme PRO 90 MB/s.
Great job ML TEAM!

Just took some more shots which I'm transferring at the moment and during the session the 5d2 crashed.  It's no big deal and the camera was fine, but a bunch of text documents appeared in the root (ASSERT00 to 11, log000 and CRASH00) and I was told to inform the devs. I'll upload the log000 file if it's needed, here is the text in the crash document:

Video Mode vs photo mode? Any speed difference?

I noticed in photo mode the speed/frame rate indicator at the bottom of the menus fluctuates?

Tried some tests this morning with the 5DM3. I am noticing vertical banding in blurred backgrounds. They appear on the dng files. Anyone else seeing this?

I've noticed this a few times on the 5D2. I've always assumed that it was an artifact from line skipping. Now that it's no longer smeared to death by the default video modes, it becomes clearer.

Between about 29.959-29.978fps and 42.2-42.3MB/s respectively. I guess this is because of there being no defined frame rate. And of course in photo mode there isn't an FPS override. The reason I wanted this to work was on the 6D you could have *drumroll* WiFi monitoring. When trying it out it kinda half worked. One half sort of working, the other half crashing the shit out of my camera :P

It's because Canon code switches between those two frame rates.

Ah I see :) So is it a possibility to override the FPS in photo mode? It would be amazing if I could monitor Liveview from my iPad while shooting!

In fact is it best I continue this over in the 6D thread?

Yes, I am seeing that too. I'm shooting normal (not 5x). I found that you can knock it right out with a little bit of Luma noise reduction in Adobe Camera RAW.

By the way, that noise reduction seems to clear up the very fine noise that I see in many of the test footage, with little loss of detail, to my eye.

It probably has to do with Canon's downsampling algorithm?

If you want it to stop switching just put on FPS override... exact FPS... but shutter values get limited.

P.S. You can monitor with wifi if you record real tiny frames... the wifi uses shoot malloc and shrinks largest contiguous to like 19MB.

My bad! Didn't realize FPS override worked. Looks like I just wasn't in LV at the time  :-[
