FFmpeg psycho-visual options - psy-rdoq
7 avril 2020, par SLVRI'm new to encoding and I like to do my encodings in x265 10bit. Currently, I'm facing a little issue with ffmpeg. I noticed when I'm using libx265 encoder output file looks a little bit blurred or small detail loss. Code I used to do my encodes is



ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -c:a copy -y output-x26510bit.mkv




I've found out psycho-visual options might help in this case. I modified my code in to



ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq 4 --rdoq-level 1 -c:a copy -y output-x26510bit.mkv




When I issue the above command, I get an error code



C:\Users\abc\Desktop\1>ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq
