SubRip Subtitle (SRT)
The most widely supported subtitle format on the planet. Plain numbered cues with start→end timestamps.
What is SRT?
SRT was created for the SubRip ripper utility and is now the lingua franca of subtitling: every video player, every YouTube uploader, every editing suite reads it. Each cue is a numbered block of plain text bracketed by a start→end timestamp written as `HH:MM:SS,mmm`. Styling is generally limited to a few HTML-style tags (<i>, <b>, <font>).
Common use cases
- YouTube / Vimeo subtitle uploads
- Open-source video player captions (VLC, MPV, Plex)
- Streaming platform delivery (sometimes via WebVTT conversion)
