I’m not sure if this is the right place to ask this, but I’ll try anyways. I’m trying to convert a lot of HEVC (H265) videos to AVC (H264) and I’m getting all these nasty artifacts in dark areas. Does anyone know why this is happening? I don’t think it’s a loss in quality, because I’m converting it to a video with a higher bit rate than the original. The H265 version does have a bit depth of 10 and the H264 with a bit depth of 8, but I’m not sure that would cause this. I’d really appreciate any help in this matter and hopefully some solution to fix this. I want the quality to be as close as possible to the original H265 version. The part of the command for video is something like this below:
-c:v libx264 -crf 23 -tune film -preset veryslow -profile:v high -level 4.1Here is just one example of this:
Original (H265)
Converted (H264)
