T.S Posted February 17, 2019 Share Posted February 17, 2019 flickering at certain ISOs, like 1250, 4000,5600 etc, other ISOs are ok. happens with N-log/10 bit, all settings and different cables were tried still no solution. please refer to the video I tested. anyone has the same issue and any solution? PS, just updated the firmware to V1.01, flickering issue still there. nikonZ6_Nlog_flickering.mov Quote Link to comment Share on other sites More sharing options...
Geoff_L Posted February 17, 2019 Share Posted February 17, 2019 Did you try the flicker reduction option, just to compare ? Quote Link to comment Share on other sites More sharing options...
T.S Posted February 17, 2019 Author Share Posted February 17, 2019 tried all the options, no help. I did the test under totally natural light. Quote Link to comment Share on other sites More sharing options...
androidlad Posted February 17, 2019 Share Posted February 17, 2019 Quote While N-Log recording is in effect, Picture Controls cannot be used, ISO sensitivity cannot be set lower than ISO 800 or to values of from Hi 0.3 to Hi 2, Active D-Lighting and high ISO noise reduction turn off automatically, and photographs will not be taken when the shutter-release button is pressed all the way down. The camera may also have trouble focusing; this is not a malfunction. The subject will be displayed in the monitor, not the viewfinder, regardless of the display mode selected, and flicker or noise may be visible in the display.

These are defects... regardless of what Nikon says. Those Jedi mind tricks only work on the weak. Quote Link to comment Share on other sites More sharing options...
T.S Posted February 17, 2019 Author Share Posted February 17, 2019 below is from Nikon support: "I tested our Z6 outdoors today, it was bright out today and even more so with the higher ISO and slower shutter speed requirement. I didn't have ND filters to use, but I had some degree of contrast at 1250 at least, and I didn't see a hint of flicker, even in the waveforms. Can you test this outside and still see an issue, the sample you sent were shot indoors. Maybe you have a bad cable or bad port or bad connection? I have not received any other similar reports at this time. If you want to have use test the camera here, please let me know. " his logic is simple: you have issues for indoor shootings , but I have tested, no issue for outdoor shootings. if you shooting moving subjects, overexposed, maybe not easy to notice this issue. then what I can say? he is a very smart guy.

anonim Posted February 17, 2019 Share Posted February 17, 2019 What to say with compassion, try to be patient and I hope you have possibility at least to change your sample of camera for another one. Maybe other users of Z6 here could test issue and in form of petition, using eoshd as voice of truly independent platform, make some sort of more pressure on Nikon support?

Geoff_L Posted February 17, 2019 Share Posted February 17, 2019 @androidlad Do you have an idea why a potential issue would only appear at certain ISOs (I ask because of your technical knowledge I'm always amazed with ! ) Quote Link to comment Share on other sites More sharing options...
T.S Posted May 16, 2019 Author Share Posted May 16, 2019 Update: updated my Z6 to the new firmware V2.0 today, flickering issue still there..no fix at all. Quote Link to comment Share on other sites More sharing options...

JeffyCan Posted September 10, 2019 Share Posted September 10, 2019 I have the same issue. I haven't tested thoroughly enough to identify the specific settings or lighting conditions that cause this. But I've seen multiple times and it's occured indoor and outdoor under natural and artificial lighting. Overexposing seems to help, but doesn't always get rid of it completely, and overexposing is not always a viable option. Serious problem that needs to be fixed.

MaximeM Posted October 23, 2019 Share Posted October 23, 2019 I just noticed the same thing at 1250 and 6400 ISO. Flickering and green/magenta color shifts... Something has to be done. TomPhoto23 1 Quote Link to comment Share on other sites More sharing options...

MaximeM Posted November 23, 2019 Share Posted November 23, 2019 Seems to be fixed on firmware 2.10: "Fixed an issue that in rare cases resulted in “noise” in the form of fine horizontal lines appearing throughout the frame in movies and the live view display." ? And as far as I can tell, It dramatically changed (at least at ISO 1250, still some weird stuff happening at 6400). Geoff CB 1 Quote Link to comment Share on other sites More sharing options...
mrtz Posted January 28, 2020 Share Posted January 28, 2020 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? Mrtz Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted January 28, 2020 Administrators Share Posted January 28, 2020 Only in ProRes RAW or via HDMI in N-LOG? Does it ever happen to internal recordings in Flat or EOSHD Z-LOG? Quote Link to comment Share on other sites More sharing options...
Zeng Posted January 28, 2020 Share Posted January 28, 2020 Noticed the same with the first few shots using prores RAW. But it seemingly disappeared after a while as if the camera needs to "warm up". Will test again. Weird. And flickering was at different ISO settings compared to mrtz's findings. Quote Link to comment Share on other sites More sharing options...
