Nikon Zr is coming

It seems if you set Resolve color management like Sidney Baker-Green describes earlier on this page, duplicate your NRaw clips, rename the other as R3D, and take both to timeline, you get Red’s tone mapping and highlight rolloff controls to NRaw clips as well. They just work from Project settings to all clips at the timeline. As a bonus you have your regular NRaw raw controls as well.

If it is true, for me, the pefect workflow for RAW use, will be the 4k Nraw converted to RED raw. As it should be around 350 Mbs, which is very good for RAW. The only thing I don't know is how do they get this from a 6k sensor. In Gerald Undone, it did look a bit mushy, but I don't zoom 400% in my shots. The 4.1 k from my Z9 is perfectly usable. But in this case it is just half of the pixel.

Tried it myself after checking Sidney's video about NEV to R3D conversion, and out of curiosity copy pasted my NRaw project clips to project created with Red settings. The NEV to R3D clips look a bit like Nraw with RED LUTs and Nraw clips look the same than in usual project created for NRaw. Hopefully the ZR R3D colors look as nice as in many YT videos. With R3D you get chroma NR though and Red's ISO settings in Raw panel. Just wanted to get familiarised what editing R3D would mean to draw conclusion whether to try ZR as a 2nd cam or not.

Here are the RED project settings. The magic being Output DRT set as RED IPP2 which unlocks Output tone map and Highlight roll off. Input colour space does not matter, and Timeline cooler space can be changed to DWG or something else.

Here is my understanding about 4K NRAW in Nikon Z6 III / Zr and Z8. I don't have the camera just gathered info from Internet. Correct me if I am wrong.

Z8 as others already mentioned uses two different methods to get 4.1K NRAW / RED RAW from 8K.
Gerald Undone gets a lot of criticism on this forum but he mentioned those methods in his Z8 review while many other reviews don't. Typically for all 4.1K from 24fps to 60fps and 120fps Nikon Z8 uses line skipping with all artifacts that come with this method. Only for 24p,25p and 30p Nikon Z8 has a special EXTENDED OVERSAMPLING mode. This method of course gives more detailed / better image. It is not without it's own issues. Those issues becomes logical when we ask ourself how do they over sample a RAW video stream and at the end get another RAW video stream ?

IMHO this small green cast in the shadows will be easy to fix. Still will require some work and time. The extended oversampling is not available for 60p and 120p. In this case APS-C crop is an option for better non line skipped image.

Nikon Z6 III / Zr 4K NRAW is line skipped, but 6K full sensor width NRAW has only slightly higher bit rates when shooting with NORMAL quality. They are comparable to Sony Intraframe codecs. 

IMHO for RAW video 24Mpx sensors represents the best balance between resolution and speed. Too many mega pixels and large portion of them should be discarded somehow for 4K RAW video or we have to deal with huge 8K filesand do the down scaling in editing. 12Mpx sensor on the other side actually has less pixels  than theory suggest are needed for perfect 4K DCI debayering. Rumors about what Sony using probably a fully stacked 24Mpx sensor in next FX3 make sense. 

Nikon Z6 III / Zr Achilles heel in NRAW so far is dynamic range / latitude. All tests of Nikon Z6 III so for show 1 stop less of both dynamic range and latitude compared to sensors in Nikon Z8, Sony 12Mpx one in ZV-E1, A7S III, FX3, FX6, 50 MPx one in A1, Sony Venice 2. They all have dynamic range between 12 and 13 stops and 8 stops of latitude. I really hope Red Raw better log profile, chroma noise reduction and 6K to 4K resolution down-scaling will give one more stop of DR and make this sensor on par with the rest. After all same sensor in non DR Boost mode in Panasonic S1 II when using ProRes RAW codec   reached 9 stops of latitude. It is hard to believe Nikon used some trimmed down version of the same sensor. 

x265 10bit 4:2:0 in latest Nikon hybrid cameras is visibly of lower quality compared to RAW video but it may turn out to be perfectly fine for most tasks and most people. Nikon x265 10 bit 4:2:0 may turn out to be as good as other brands x265 10bit 4:2:2. I don't know until I try it myself or see a detailed test.   

Between Nikon Z6 III and Zr I would choose Z6 III. It has good EVF, shutter, Full HDMI port and is a true hybrid. Internally for video they are practically the same and by renaming NRAW video files we get access to the better RED RAW pipeline and color science in Resolve. Current Nikon Z6 III price in a local photo shop is 2050E. Nikon Zr price is 2375 Euro and camera is not yet available. Nikon Z6 III doesn't sell well, price was decreased significantly from original 2500-2800 Еuro most likely because it doesn't offer significant upgrade for photo shooters and all those talks about lower dynamic range. Second hand Z6 III bodies pop up locally from time to time in the 1700-1800 Euro range and still with warranty.

IMHO Nikon Z6 III and Zr are for people who want to shoot RAW video. Theory and practice tell us 10bit 4:2:2 is equally good but sometimes we just want something 🙂, for whatever reason. 12bit NRAW with RED RAW hack is really a great choice because it offers fairly compressed industry standard RAW codec. ProRes RAW has higher bit rates. 

I edited in Resolve some sample NRAW video clips from Nikon Z8 and Z6 III and can say that if video is exposed properly there is no need of noise reduction. Editing, color correcting and  grading them is not more difficult or time consuming than SLog3 internal footage from Sony.  They take more space but still nothing crazy and  for certain projects and people it could be acceptable.  

Bottom line: If you want to shoot RAW Nikon Zr, Z6 III and Z8 as well are great options, first two being quite affordable. I am worming up to the idea to get Nikon Z6 III. Use it some time and compared it with Sony ZV-E1 which has one of the best Sony sensors for video. Then eventually keep one of the two and sell the other.

Pretty good summary. After shooting NRaw almost a year now with Z6iii I can relate to almost all of that.
According to Gerald and Cinematools Z6iii FX 4k NRaw is line skipped but DX is pixel to pixel, which is the reason why in Cinematools’ Z8 vs Z6iii comparison the 4k120p with Z6iii looks better.

The only extra step with NRaw IMHO is to use Resolve to trim the NRaw files and export important parts via Resolve’s Media management. If you do the Red Raw hack after export, Resolve won’t accept the renamed files. If you do the hack first, Resolve won’t export the trimmed R3D files. 
Have not tried Red CineX pro though. Hopefully it or some other method works with the Zr’s R3D NE Raw files.
