Unrelated: Generally, you shouldn't force an input format and certainly not for avi. > -global_header -fflags +genpts You want -fflags +genpts to have an effect on your input file: $ ffmpeg -fflags +genpts -i vid.avi > -vsync -1 Unrelated: This must be a bad idea with -c copy (or it has no effect). > -map_metadata -1 -map_chapters -1 > -threads 0 -codec:a:0 ac3 -ac 6 -ab 192000 -y "/tmp/vid.mkv" -threads 0 is the default, "-ac 6" can be bad, and I strongly suggest not to re-encode ac3 audio to ac3, even less so with a higher bitrate. > ffmpeg version 4.0.3 Copyright (c) 2000-2018 the FFmpeg developers For future questions, please remember that only current FFmpeg git head is supported here.
