Noise Reduction Bad Work, CANON EOS R
Noise Reduction does not work at normal preview size.
50% Noise Reduction preview works, but photo is poor
The wrong color is also the export
All exported photos are in bad color.

Higher ISO - Larger photo color error
Very bad work for Canon EOS R0 -
You need to raise a support request as they will be able to help.

Did you get any response from PhaseOne? I'm seeing the same problem, although in the Mac version. Above iso3200 I see an extreme colour shift when zooming in and/or exporting. At iso12800 it is basically unusable, everything goes into red tones.Looks to have something to do with the noise reduction? 0 -

Most current documentation is for v. 11. It says re. Luminance Noise Reduction:
"...and check the effect in the Viewer at 100% magnification."

The problem is not the effect itself but the huge colour shift at higher iso. Making C1 unusable at basically anything over iso3200 for the R.0 -

Seems you are contradicting the OP???

No I think it is a "lost in translation" thing. It's not the actual typical smearing effect of noise reduction that is the problem. The problem is that the noise reduction in one way or another results in a, really big, colour shift. A Problem normally not associated with Noise Reduction. At iso12800 is even so that I have greens and yellows completely shift into the red tones.0 -

I have a sample image from DPReview shot at ISO6400 and so far nothing I have tried has introduced any colour change worthy of note in greens and yellows.
Are you able to share a sample file with which you see the problem? It would be good to understand better what to look for.

Petr,
Firstly thank you for the files. It is very interesting to see the results of the EOS R at high ISO and have an opportunity to experiment with them.
I think this may be a matter of personal preferences about how you want the image to appear.
Firstly let me say that I think the FOTO - 018.jpg looks over exposed to me. (I work with my screen brightness at the lowest setting so that is not an influence.) Let me use that image as a point of reference.
As an example of over exposure, on the extreme right the male subject's shoulder has no detail in the shirt material in any of your sample shots but there is detail to be seen by reducing the exposure in some way. In addition the dark (black?) areas of the lady's jacket can be much darker, with a little adjustment, and that greatly improves the look, in my opinion. Especially when dealing with ISO 32000 noise.
Secondly I have to say that I am quite impressed with the RAW image considering it is ISO 32000.
Capture One can deliver and control detail in all but the most over-exposed spots.
Obviously I am not familiar the the actual colours in the image and I also suspect you have multiple light sources with different colour casts involved but some White Balance adjustments allow me to get versions that seem to work as images for a range of personal preferences about the colours in clothing versus skin tones. Chosing which is best would be a matter of personal preference.
With the use of some layers and localised White Balance adjustments a very even base colour balance could be achieved. However that is not always a great idea - it may lose some of the "atmosphere" around the event.
Your OK and KO jpgs are interesting.
The OK version looks a little yellow to me. At 50% zoom it is less yellow but, like the FOTO jpg, looks a little over exposed and so unsaturated.
I have in the past noted that Canon images (it may also apply to others manufacturers but most of my cameras are Canon) when compressed (as they are to fit the screen in this case) will tend to look yellow in places because once you have thrown away some pixels to reduce the size of the image to fit the available screen space any mainly yellow pixel groups will tend to stand out more to the viewing eye. Even if they are just a few pixels wide they can dominate especially over green in grass but also over red.
As soon as you zoom in (in my case anything over 50% depending on the file size as that is the point where the compression used to fit the screen shows the effect) the yellow dominance is reduced. This is mostly a screen effect not something that would also be a strong influence in a print at the resolution available from this file.
I have some alternative edits in preparation. I want to make sure that I have not left anything unnecessary in the changes (to avoid confusion or mis-direction) before sending them. I will try and complete that today and hope to send something this evening.

This indeed the same problem I am seeing. It is not the question which rendering is right but that in the current situation C1 is unusable for work with Canon EOS R files.
I have seen situations where the effect is much worse even than in these examples. As the effect seems to worsen at higher iso, I assumed it is noise reduction that is the culprit. I, unfortunately, can't show any examples as the beta version expired and am not willing to upgrade for the current price when such problems do exist.0 -

You can download and run the V12 trial for 30 days.
I really don't see a huge colour shift and some very nice results are more than possible.
I have just re-visited the basic Noise Reduction settings and used some colour readouts to see if anything is happening when values are changed using the sliders.
There are two very small areas on the image that change with any amount of significance when making some extreme adjustments with the Colour slider of the Noise Reduction tool. It's difficult to spot them and they both have the same characteristics for areas with a blue/mid brown colour before adjustment. The adjustment removes the brown since, viewed at 100 %, the pattern involved is mostly blue anyway.
Otherwise the values are stable.
I think you may be battling the "Auto" curve selection in the Base Characteristics tool?
Try this.
In the Base Characteristics Tool set the Curve to Linear.
Set the White Balance to something close to Kelvin 3000 and (In the sample file provided by Petr. For other files base the selection on the light source temperature (or use the picker to find a suitable grey, white or black point) and the tint to choice but I would think somewhere between -1 and +3 looks about right on my screen (again for the sample image).
In Exposure try something like
Contrast -11
Brightness +13
Saturation +17
Contrast and Saturation will lift the Linear curve.
Brightness is a matter of choice. I would leave it darker but +13 gets the mid tones somewhere near the OOC jpg and gives a point of reference.
In the HDR tool set Highlight to 66 to recover some detail in the burned out areas.
In the levels tool set the Clip point value on the right lower adjustment to about 239.
You might also benefit from an Auto Levels if you set the adjustment method to separate channels using the Preferences tool.
A slight S curve in the Luma tab of the Curves tool is also useful. Drop the dark end a touch and raise the light end a touch.
After that, if required, you can experiment with the benefits of the Clarity tool (perhaps some negative Clarity but a little +ve structure) and using some layers to to adjust the dark areas using Luma value selections and Noise adjustments only for those selections although there are some other adjustments that, in my opinion, are more effective than just NR in the sample image.
Also, by selecting on Luma range the adjustments are easily copied for use across other images shot in the same conditions.
HTH.

ETA. I have just seen that there is another download available. The above response is offered before I have looked at the new files.0 -

Yes, this shows the problem I am seeing too quite well. This is by no means a small shift. At lower ISO I also found this to be happening, just to a lesser degree. At iso1600 it does happen but it is hard to catch.
PS. good idea SFA, to download the trial, didn't think about it.0
