If you have a video file named something like You.S02E05.mkv or you.s02e05.mp4 , ffmpeg is the go‑to command‑line tool to inspect, convert, trim, compress, or extract audio from that episode.

ffmpeg -i you.s02e05.mkv -vn -c:a copy you.s02e05_audio.aac Check track numbers with ffmpeg -i file.mkv . Suppose video track #0, audio #1, subtitles #2. Remove subtitles:
