To convert your fancy 4K phone video into something the evidence room can read: the rookie s02 ffmpeg
If your Season 2 files have inconsistent naming conventions (e.g., the.rookie.2018.1080p.mkv , The Rookie - S02E02.mkv ), FFmpeg can be used within a shell script to standardize the metadata without re-encoding (using -c copy ). ffmpeg -i suspicious_call
ffmpeg -i video.mkv -vf subtitles=subtitle.srt -c:a copy output.mkv The Rookie - S02E02.mkv )
