  • Grey squared artifacts after HEVC 10-bit encoding using FFmpeg's NVENC encoder

    20 juillet 2017, par Cryman

    Recently I purchased a brand new GPU - AORUS GeForce GTX 1080 Ti. I found out that it supports HEVC 10-bit encoding, so I wanted to give that a try. Unfortunately, after encoding I noticed some artifacts, which occur in dark scenes and last one frame of the video. You can see them on these screenshots :

    Screenshot of a still from an animated scene. There is an artifact near the bottom and slightly to the left. It is square shaped with white squiggles.

    Screenshot of a still from another animated scene. The artifact looks the same as in the previous image but is in a different location, higher up and closer to the center.

    I was wondering if someone could help me figure out what might be the cause of these artifacts and how I can get rid of them.

    Here is the MI of the source video :
