Hello. While using my X-T3 I encountered artifacts in video mode. With a white balance of 2500 and a transition to the blue spectrum, purple spots appear.

Additional settings: 4k or FullHD, eterna picture prof, S tone -2, iso 640,  diaphragm 2.8-22, DR 400, shutter speed 1\40 - 1\200. Software 3.00

This is evident on dark objects or on a yellow-green color. In the video, this effect is not visible. With atomos ninja 5 this effect is present. I also filmed this on video. Who faced such a problem? What could it be? 

Video artifact   (atomos ninja 5) : 

Thank you in advance.

Yes I noticed these lowlight compression artefacts as well, Square blocks...like being burned in on the sensor. Any suggests Fuji?

Probably you have already figured out the solution, but I noticed that al the film simulations loose a stop or so of light so you will have to have a lot more light. Also - what if you set DR at 100? I think you may be causing issues using DR - maybe do a test at 100 with lots of ight and also compare to flog at iso800 and see if the issue is the simulation for the exposure and DR you have selected. BTW can you look at my post and maybe help with Ninja V sample?

Hi, I wrote to the representative office of Russia. Here is the official answer (translated into english by google translator):

We conducted a thorough diagnosis and revealed the appearance of a similar effect in some conditions both on your camera and on other test specimens. It is impossible to eliminate this phenomenon, since its appearance is due to the very structure of the camera components. This effect is not a malfunction, your camera passes the tests and meets the declared technical specifications, so you can continue to use the camera. We understand that the appearance of an effect may impose limitations in some specific shooting conditions. If the manufacturer develops any change regarding this effect, we will be able to service your camera. We hope for your understanding Regards, Fujifilm Information Center.

    • Found the simple answer to my own question. Having assigned Auto ISO to the rear dial, I only have to push in the dial to make the Auto ISO options appear, then turn the dial to choose. Nice and fast.
    • Hello All, I am returning to photography after a decades-long hiatus that was prompted by my loss of access to a darkroom. Digital rendered that excuse moot, so I now return with a recently purchased XT5. I am from the Hudson River Valley in New York where I have spent the past five decades engaged in environmental work, mostly on the Hudson. I teach at Pace University where I direct the Gale Epstein Center for Technology, Policy and the Environment. My project ahead is documenting the unseen Hudson, a combination of the obscure, under-appreciated, and invisible - a street-style approach to people, places and things that make the river what it is. There will be little landscape, if any. The "Mighty Hudson" is well-documented. If nothing else, it will be a mission-driven project to bring me back to photography while learning my camera. I look forward to everything this amazing site can teach me. Cronin
    • Hi,   I would really appreciate if someone could answer this question. Is it possible to have the X-T4 shoot in AF-S for photo mode and AF-C in video mode while the front lever is left at AF-S?  If so, how would this be done or wher in the menu system would I set this up? This is similare to setting the apeture at f/2.8 for photo mode but fioming at f/4 in video which I already have setup. Thanks and kind regards
    • According to the manual you can assign auto ISO to any one of the function buttons but I've never tried it. (It's not something I frequently change so all my function buttons do other things.)
    • Hello, I have a new xt5 and have enjoyed its setup, until now. I hope someone with patience can help me through my ISO dilemma. My question: I have assigned settings for Auto ISO 1,2 and 3.  Should I be able to select Auto ISO 1, 2, or 3 for a shot? If so, how?  Or is the camera supposed to. At present, my screen shows Auto ISO 3, and never changes. I assigned ISO to the rear dial to no effect. Of course, when I half depress the shutter button is see the actual ISO in real time, but the function of the Auto ISO and how to control it has me confused. Thanks for any help.
