Yikes! :) But why is your CF whitebalance right and the raw2dng opened in ACR totally wrong?
Is there some camera wb-data transfered in your process? Maybe I should try set the wrong WB in camera and see if that wrong get's copied to CF.
#2
Yep but you do write something I guess? Why else is the 5D-CF file correct and BMCC totally green?
#3
I just played with my BMC files once more. I have to transfer the RED/GREEN/BLUE values from the whitebalance panel in Cineform Studio to resolve to get a clean BMCC file.

The 5D-CF file loads just fine in Resolve, I have no idea why, David may know. And about the quality of that BMCC-debayer I'll continue in the other forum ;)
#4
Yep, just download it and see for yourself :)
As long as you export only 1920x1080 and don't need the Resolve-NR it's free.

Too bad the raw control is not implemented with cineform. With DNG you can set exposure/wb/shift, with R3D you can set a lot in Resolve directly :(
Really hoping to find a way to change wb/curve, I wonder how David's converter set's the WB from the .RAW

The cineform sample has some color artifacts; was it debayered by the cineform software, or with the Resolve algorithm? If by CineForm, which debayering method did you use?

It's the same .mov! Resolve normally totally ignores the Cineform Studio processing and reads pure raw data. With that you get this flat but high quality image. But there is no way to change output curve or white balance.
The 3rd picture is with David's Resolve patch. What that patch does is force Resolve to act like any other windows application meaning get the debayered processed image from CineformStudio. All metadata settings in Cineform are shown this way and I used advanced detail 2 as debayer algorithm.

So the best quality would be to go via Resolve unfortunately I don't know how to change whitebalance/curve with that. That's my question to David, is there a way to edit the .mov because there IS some wb-information stored in the file why else would it be fairly accurate and not totally of ;)

Ok, did some more digging with the patched and unpatched version for Resolve.
Remember the green cast on the unpatched version David? It's apparently a BMCC only problem. The 5D-CF-RAW files open just fine in Resolve in the unpatched version. They open with very little contrast I expect this to be the decoding curve I set when converting. Unfortunately there is no way to set the whitebalance as Studio changes are completely ignored BUT the whitebalance seems right, are you reading it from the .RAW file? It looks ok whereas the DNG in ACR always have that magenta shift?

Ok now for the quality comparsion. Resolve works lovely :)
As it opened very flat I added some contrast, thats all I did in Resolve, if you compare it to the ACR I opened with sharpening 0 and noisereduction 0 they almost look absolutely identical! I then installed the patch, chose ADV Detail 2 and reexported (with no contrast adjustements) from Resolve. Too bad there is no way to set the whitebalance/decoding curve for Resolve. Is there maybe a way to modify the .mov file instead of doing just metadata via Studio?





And well the BMCC images are completely of, but wrong topic for this forum :)
#7
Yes that pink highlight restauration is ACR magic.

@Samuel: I was surprised by the difference too, the BMC is definately sharper in that test. But keep in mind that those are very very fine lines and small fonts so in real world the .RAW is just fine
#8
Ahh I forgot. Ok let's assume I run the version with no patch, how can I set whitebalance and basis settings in Resolve to get rid of that green cast?
#9
ehm Samuel wait, I did not run cineform on that test. I did CR2 (still image), RAW (via ACR) and H264. To be honest I don't remember the sharpening settings but I think it was just the default 25 with radius 1.0 - For the CR2 I used resize sharper in photoshop to resize to HD resolution.

Isn't CF advance detail 2 the best option for good sharpnes with no excessive artifacts David?
#10
Is Resolve doing the demosaic not cineform? So no matter what I select in GoPro Studio Resolve handels it? Or does this behaviour change since I use your patched dll?
#11
Take a look at my comparsion pics Samuel. It may not be as sharp as ACR but no way it's as mushy as the H264 :)

BTW I just opened the image for comparsion in Photoshop. As nice as Cineform is, the Adobe Denoiser does a great job on the bookshelf when lifting the shadows ...

  So this should work -(8,0,1928,960) -- except I introduced a bug it doesn't.  Fix coming.

Works perfectly, thanks alot! Imho this is the way to film with the 5D3 (selecting 2048 it jumps to 1928) because otherwise you'll always have the 2 black rows on the left.

Quote from: DANewman on May 27, 2013, 06:20:35 PMI did have a look at the BMDFilm output curve, and it is a little odd.  It is likely has BMD sensor calibration stuff in it, the curve we use for Protune and others, mathematically models the mapping of linear to log and back again, the BMD curve don't fit our models.

Oh ok didn't know that. I found a thread on bmcuser where somebody found a simulation using the Cineon 95 curve. I did some further testing and pushing with some frames of mine and found a pretty matching preset. BMDfilm compresses/lifts the shadows a little bit more but otherwise it fit's good imho. (Here's the link with the BMCC comparsion: http://www.bmcuser.com/showthread.php?2306-Cineform-Raw-BMD-Film-Curve&p=65225&viewfull=1#post65225)

Attached a screenshot of GoProCineformStudio with Protune curve, one with my simulated bmdfilm and one with the bmd to rec.709 lut applied. Yes I'm digging more into the shadows on the bmdfilm like grade and yes whitebalance probably has to get adjusted it was just a quick apply with no correction and my settings were originally for the bmcc.



#14
Already found a bug..,kinda :)

I always record in 1928 width because we have 2 lines garbage on the left. recording 1928 and cutting 7 pixel on the left and 1 pixel on the right gives exactly the same FOV as a CR2 still. But if I convert this raw with the converter and want to play it back the program crashes. Be it the quicktime player or gopro studio or windows media player when trying an avi.
I tried to crop it via parameter but seem to do it wrong? How are the parameters? is -(7,0,1926,959) correct?
#15
Happy to give it a try David, do you still need some .raw files?

Did you take a look at the BMDfilm output curve? Do you think it would be possible to get that as output so that I can grade in Resolve with a flat image (like the bmdfilm)?
#16
So you can record 1920x1080 with no dropped frames on the Transcend 32?
#17
How fast are your 32 in liveview?
#18
I bought the Transcend based on the chart but that is for the 32gb. Still it says write speed 120mb/s on the box. Dunno if my one is just a bad batch or if the 32 really is that much faster then the 64gb
#19
My one unfortunately is not enough for 1920x1080 @24p - even with the 3Dhack it drops 1 frame every ~2 seconds.
Speed is unchanged with or without global draw. In 1928x960 I can get 25p even with global draw on
#20
Uhm just a stupid question. Why is 60p such a strange crop/stretched? If I choose a low resolution and do 25p it takes a crop in the right aspect ratio, if I select 50p it takes all height? Any reason for that?
#21
Ah found the hack3d.

With that enabled in 1920x1080 it skipps a frame about every 2 seconds

Have you tried turning on Hak3d in the raw menu?

Hak3D?

--> when running benchmark from photomode i get depending on buffer ~100
--> in videomode i get 85-95mb/s depending on buffer, 95 would be enough but I don't know what kind of buffer is used
#23
Unfortunately I can't get 24p working in full 1920x1080 mode on my 1000x Transcend 64gb. I posted some benchmarks in the other thread. If I read the already posted chart correctly the 32gb transcend seems to be faster. In 1920x1080 I have about 1 frame skipped every 1-2 seconds :( Just a tad too slow :(
#24
One more time Transcend 64GB 1000x - video mode - this time with HDMI enabled (even less performance)
