Nikon Z RAW video support

Another option that Nikon could have done is to offer a 1.5x cropped raw video without interpolation. In this case it would have been RAW without line skipping.

 

There is no stupidity involved here, only different compromises to choose from. 

On the Z 6 the 1.5x cropped option is available for HDMI RAW: UHD DX (as opposed to UHD FX). I have not seen any YouTube reviews that assess the image quality of that option.

Cliff, maybe you should read my blog article first ;)

Why did you reach out to Marc Jungbluth to do test using a ZP chart on his iPad?  Give it a rest.  Marc Jungbluth has done more than anyone showing the correct Z6 - Pro Res RAW  workflow and showing real world footage.  It's clear Marc Jungbluth is uncomfortable do this test for you.

You have a weird vendetta against Nikon for some reason.

Looks like bad color grading.

 

I agree, but then we probably disagree about what  "good" color grading is (and also how to post comments). The problem is the transformation in Edius from REC2020 to REC709 (no LUT) gives you not a good base. My criterion is reproducing what I saw (in this case). The colors are fine by that criterion *except* for the skin tones, which I just could not get right. The colors look fine to me in the other RAW video shot in the garden (above the "faces" video). If you think that the color grading in that video is "bad", then we surely disagree. Also, the WB was all over the place, and I do not think ProResRAW is like RAW from stills in that regard.

Anyway, it would be helpful to have a LUT from Nikon to go from RAW to REC709 and REC2020, and a better understanding about what ProRes RAW clips reflect in terms of camera settings.

Anyone wants a RAW clip or two to play with, I am happy to provide.

I apologize. I did not mean to make a blanket statement about that video and that wasn't fair.  

Did you color grade in resolve?

My complaint on color grading is if you go to 00:18 and look at the blonde lady looking at her phone.  Her skin tone looks flat and painted on. You see no definition or highlight on her face.  This looks like you color graded with power-windows and adjusted skin tones too far the wrong way, not in color but saturation, gamma and the rest.  All the skin look this way. 

Everyone in this video looks like the skin areas have been artificially adjusted.  Am I correct that you added these adjustment?

Can you provide a RAW clip?

I agree with you about the blonde as being the worst case, I tried hard to fix that look, but could never get it right. 

I use Windows. The only option is Edius. I had never used Edius before, so I was on a learning curve. This is what Edius does: it puts an HLG gamma curve on the ProResRAW clip and assumes it is REC2020 color, which it is. I chose  REC709 as my project, so in principle it should have made the transformation and I was looking at REC709.  This, as I noted, seemed to work ok for the garden video (with no skin). But in the video with lots of people the skins were all over the map in looks. Lighting conditions were the worst - the blonde has very bright late afternoon (very yellow) sunlight directly hitting her face, but I do not think it was clipped. WB was also odd in some cases (this was run and gun, so AWB) and I had to try and correct color. Everything was with scopes as guidance as well as my eyesight. It is the most trouble I hav had working with any non REC709 file (I have shot with Slog2, C-Log3, N-Log, Z-log! and even RAW DNG from the original BMPCC).

I can provide a RAW clip - they are gigantic, so I need a method for that. Choose a scene you would like to poke at.

That footage looks great.  How does RAW compare to 10bit N-log footage?
