What happens if add after libx264 the parameter " -vpre hq " ..... ie something like:
ffmpeg -y -i Warriors_of_the_net_CZ-MPEG1_Web_PAL.mpg -vcodec libx264 -vpre hq -acodec copy output.mkv -threads 0 I find I need the " -vpre hq" or " -vpre max " or " -vpre <option> " with some applicable option every time I use ffmpeg with libx264 to encode.
