Hello,
I have the same problem with my Z6 (Firmware 2.2, with ProRes RAW):
When recording videos with N-LOG or RAW (I had the problem already before RAW was unlocked) with an Atomos Ninja V Recorder there is a flickering, especially in shadows and dark parts of the image.
IT MAKES THE RECORDING UNUSABLE.
I tried a motive (books on a desk in a room at night, only a desk lamp with normal old bulb – so no LEDs, TVs, projectors) with all ISO settings. The flickering came up at these ISO settings: 160 (extreme!), 320, 400, 500, 640, 1600, 2500, 3200, 4000. It did not occur at these: 100, 125, 200, 250, 800, 1000, 1250, 2000, 5000, 6400, 8000,10000,12800,16000.
I changed the Nikons flicker reduction from "automatic" to "50 hz" to "60 hz", did not change anything.
I have to say I am desperate. I invested in a Z6 with the Atomos Ninja V plus a Nikon Z 24-70 2.8 lens, mostly for using it in theatres, filming dance performances with theatre lights, sometimes with video projections, and at the moment it is really not useable.
But if everybody would have this problem with this gear, I suppose there would be a bigger shitstorm going on?
So maybe it is really my camera, or the Ninja V that needs to be repaired?
Did anyone of you have his device repaired or exchanged?
