Can anyone tell me why the histogram and other scopes go away when I have raw_rec activated? Of course, global draw turns off when recording but when I turn Raw video on the audio meters and some other information cover up the lower part of the screen where the scopes usually go. This is in all builds I've tried since the 9th of Oct. build.

When I turn raw_rec off the scopes come back.

I found this tutorial in another thread when I was having debayering problems with Resolve and thought I would share here. Resolve 10 seems to have fixed that issue but I still get some very ugly colour moire between tree leaves etc when shooting in full sensor mode (even ACR/AE doesn't do away with that). This simple trick fixes it amazingly well.

Hey dmk, where did you order the card from ? I've seen the Komputerbay cards on Amazon but they won't ship one to Australia 

Take a look on Ebay. I just ordered one from there and it came promptly - I had to pay about 20 bucks for shipping but it was a lot cheaper than Amazon.

That doesn't help, because the auto-start leaves gaps in the clips. I need continuous clips with no gaps.

I was talking about RAW recording, sorry. I realised afterwards that this is about H264 continuous recording. For RAW it just keeps on going without a pause.

I have been looking around and found that actually the purple fringeing is a common problem with Resolve and RAW data - it isn't a 7D problem specifically. There are some tutorials for mostly fixing it but I think from what I can see in experimenting that Resolve 10 is already doing a better job with this than 9. Time will tell.

I also ran some test on 7D+Lexar 1000X.  Used Sep 12th build.

Speed:
I had been keeping track of recording speed and this build is the fastest with speeds as good as Alex build for 7D.  I also tested the mlv_rec and was slightly slower.
Regarding speed the strange thing is that I got a bit faster speeds at cropped mode.
Highest recording speed at 1728x972 at 29.97 and cropped was 77.2 MB/s

Pink Frames:
Only got pink frames at 60 and 48 fps video.

Video Quality at ISO 400-800:
Raw DNG has lots of hot pixels (red) and other colors too.
The proxy videos generated by RAWANIZER and dcraw where pretty ugly!
Videos via ACR 8.2 RC to TIFF to Vegas, were of excellent quality and hot pixels removed by ACR.
When compared to 5D3 videos I could notice a little more noise but comparable sharpness and color.

Do you have Davinci Resolve? It would be interesting to compare your files processed that way for each camera. I want to get to the bottom of this fringeing issue I'm seeing.

I just shot an event video on a 5d Mkiii and a 7d, both shooting raw, all footage processed in Da Vinci.  The 5d stuff looked flawless.  As sharp as the C100, but with better color, and no compression issues.

The 7d stuff on the other hand, had purple fringes on all the highlights, and totally unusable aliasing and moire on most horizontal lines.  Short of a VAF filter or a stable implementation of the crop, I don't think I'd try to shoot this way again.

That being said, I still do prefer the look of the raw images to the h.264.  The work being done here is incredible.

Did you use a LUT when you were processing in Resolve? I have found the exact same ugly fringeing when using "Hunter's LUT" with my 7D raw footage. If I turn the LUT off and then process manually it seems to go away. Also, if I process through AE it is even cleaner (but this is the slowest possible way to work). I wonder, if this is a debayering issue, why 5Diii footage would look ok and if there is a way to change it.
