: Outlander often includes "forced" subtitles for non-English dialogue. Ensure you use -c:s copy or -c:s mov_text (for MP4) to keep these tracks intact.

: You would use a command that specifies the input URL and the output file name. For example:

ffprobe -v error -show_entries stream=codec_name,start_time outlander_s03e04.mkv

ffmpeg -i outlander_s03e01.mkv -vf "subtitles=subs.srt" -c:a copy outlander_s03e01_hardsub.mp4

ffmpeg -i outlander_s03e01.mkv -c:v libx264 -crf 18 -preset medium -c:a copy outlander_s03e01_plex.mkv
