DVR16.2.8, DVR 17B8

Hello.
When editing and outputting in the h.264 codec, the video is rendered with artifacts (video shifts, strobes), there are no problems with the FullHD rendering, only 4k. If the rendering is done by the processor, then everything is fine, the problem manifests itself only on the GPU and when rendering 4k video.

I have all the latest drivers for the AMD PX580 video card installed. I also tried to install different versions of the drivers for the video card, but the problem has not disappeared. It is possible that Davinci is somehow incorrectly processing video with my video card.

To check the video card, I installed the latest Adobe Premiere Pro and the video rendering in 4k took place without problems and artifacts.
I also checked the video card for the Mojave hackintosh, the metal codec renders video in 4k without artifacts and friezes, the problem is observed in Davinchi under Windows 10 x64

My computer:
Ryzen 5 2600
Memory - 16GB
Graphics Card - RX 580 8Gb Nitro +
SSD Gigabyte for Windows 10 x64

Artifacts appear randomly

That's why I prefer using Native to create deliverables. I only ever use the GPU for creating fast review copies.

If you enable output via Nativ, the same failure occurs, while the use of the GPU is enabled in the davinchi settings. Solved the problem so far only by converting to AppleProres.

Are you using transcode + prefer quality with AMD encoder? I have the RX580, haven't noticed such attracts the last time I exported 4K but I usually export it in h.265.

Hi. I Use these setting in output video, if the output video size is changed, for example, for Instagram, then artifacts appear more often than when outputting in 4k.

Got it.

What's your source media?

Hi.

Sources - Sony a7III 25fps 4k/100Mbs. S-log3, S-Gamut3.Cine.
So that there are no artifacts during editing and rendering, I convert the sources to Apple Prores via Adobe media encoder.
