SRT is the most common subtitle format: numbered caption blocks with start–end timestamps, supported by nearly every video player and editing tool.
Typical use: Uploading captions to YouTube or importing them into video editors usually starts with an SRT file.
About the SRT format
SRT (SubRip) is the most widely supported subtitle format in existence: numbered cues, a `HH:MM:SS,mmm --> HH:MM:SS,mmm` timecode line, then the text, with a blank line between cues. It is plain text, so it diffs cleanly, edits in any editor, and is accepted by virtually every video player, editor and YouTube.
It is deliberately minimal: no styling beyond basic HTML-ish tags (italic, bold), no positioning control, no metadata. Millisecond precision in the timecodes is its only structural luxury. When you need richer typography or web embedding, WebVTT is the modern upgrade path.
