2.7-2.8K 2.39:1 looks like the sweet spot for repeatable continuous recording on the Toshiba 1066x card. By "repeatable" I mean repeatable near 100% of the time. Same goes for 3.3K anamorphic scope: 2272x1364 with a 1.5x anamorphic lens.

Understood, but from a cinematography perspective; I need to figure out what resolution will give the card enough headroom to write at that resolution continuously at least 90-95% of the time; so far it looks like that's somewhere in the 2.5-2.6K range for 24p 2.39:1, which is still great.

I've found a couple of issues in both builds. The first is nothing major: when you change a resolution in the crop mode menu, say 3K to UHD, you have to exit the ML menu before you can adjust the resolution size in the raw video menu. The other issue is making me pull out what little hair I have left: the lossless compression ratio appears to have a mind of its own, it's like a recalcitrant AI. At one point it was compressing at 51% on the 1st build:



When I loaded the 2nd build it started at 85%:



So I had to scale down to:



After a few seconds of recording the compression went to 70%:



Then when I try to increase the resolution I get this [Expect xxxx frames]:



A battery pull gets rid of the [Expect xxxx frames], but on the 2nd build it reappears when I try to scale up the resolution. So I went back to the 1st build to see if I could record at 3.3K 51% lossless again. Initially I was able to get this setting:



That was a bit much for the card, it stopped recording after a few seconds resulting in the dreaded [Expect xxxx frames]:



Taking me back to square one where I had to scale the resolution back down:



Ideally the compression ratio would either be fixed, or manually adjustable.

I've never had to use it, but I keep a BMMCC in my camera bag just in case. The bleeding edge is not for everyone.

I got punk'd last year and I've been testing/using ML raw since the first build. I forgot what bloody day it was! Zee Germans love their schadenfreude, look at Greece :p

@a1ex Killjoy!

Sounds and looks good.

I just checked the new build (89), same random black cube bug when using the sharpness filter. The sharpness filter appears to degrade the image even on a minimal setting, so probably best to use another app to sharpen for now. It's fast, but I'm still getting higher quality renders from ACR/After Effects, but I need to play with it a bit more. It's definitely a good option for creating proxys.

I'm getting random black cubes on the 85 build (Mac Pro, 10.11.4, GTX 980). @Teamsleepkid said the sharpness filter was generating white boxes.

Cool, thx.

I'm getting the impression from the cinema5D article and video that 1080p is downsampled not pixel binned.

@pedz Yes it's true re raw video. The 5D Mk3 can record full HD (1080p) 24fps raw, and 720p 60p raw. Aspect ratio is adjustable, and there are many other pro features. The image quality is unmatched by anything in its price range including the Blackmagic cameras.

You don't have to make any promises, everybody here has a life (except a1ex, pretty sure he's a Replicant). Just introduce yourself to a1ex. Any help would be most appreciated by the ML community.

If you use the build and post workflow I've suggested you shouldn't have any problems. Just convert your CDNG files to ProRes4444 in After Effects and you can edit and grade in whatever application you prefer.

@anDyIII try this: https://drive.google.com/open?id=0BzJ3L6nv6Fn0ZHhSUTdCRVNSWG8
You'll get an error message because the pink frames fix module is from a 1.1.3 build, but apart from that it works ok for me.

It sounds like a problem with the debayering tools because the file has already gone through the MLV to dng conversion process, and ACR is debayering it properly. I debayer my 5D MK3 MLV files with MLVFS/Adobe camera raw/After Effects because the debayered IQ is noticeably better than Resolve. The only drawback is it's a slower and less convenient method.

Did you select the "highlight recovery" box in Resolve?

@anDyIII I opened that dng in photoshop: there's no clipping.

I like the grade: filmic, but not overdone. The trick to getting anything to look half decent on youtube is to upscale to 4k, but even then it still only looks half as good as 1080p on vimeo.

Otherwise use ACR to debayer, denoise, and sharpen; export as prores4444, and grade in Resolve.

Vintage Leica (circa 1970) 35mm and 90mm Summicron-r. I shoot almost exclusively with these and 24mm, 60mm, and 135mm Elmarit-r. They all have Leitax.com EF adapters.

This one's H.264.

Hey Axel. My partner's an art director; she may be able to help you with the pdf if you're still punishing yourself.

Plus why would anyone drop 1k on a smallHD 501 and want to monitor a lo-fi image?

Pretty please with magic mushies on top 

Have you exFat formatted your CF card and enabled exFat in the ML menu? 

I concur. Don't be a dick Erik. Respect is due for the brilliant work done by the ML developers. Be thankful for what you're given and don't whinge. If you want perfection buy an Alexa.

I tried data rates 5-10MB/s lower, no change.
