SRT file
SRT (SubRip Text) is the simplest and most widely supported subtitle format: numbered blocks of start/end timecodes and text lines, in a plain-text file.
SRT's limitation is styling — no colors, fonts or positioning — which is exactly why it is universally compatible. It is the safe interchange format; richer needs move to VTT or broadcast formats.
