If engsub means softcoded subtitles are present:
( si=0 selects first subtitle stream)
Wait, maybe it's related to converting a subtitle file. If it's a .srt or .vtt file for subtitles, converting to another format? But "min.top" doesn't ring a bell. Could "min" be minified version, and "top" something else? Or perhaps the user is referring to a video file conversion, such as changing resolution or codec? nsfs324engsub convert020052 min top
