Official standards and scope
YouTube documents basic SubViewer/SBV caption files and its API download format, while Matroska documents the widely used SRT structure. This page trims the whole input, splits blocks on blank lines, treats the first line of each block as a comma-separated start and end time, and joins all remaining lines as cue text. A block without a comma or without text is silently skipped. Times may omit hours, may use a dot or comma before one to three fractional digits, and must keep minutes and seconds at 59 or below; output is normalized to sequential SRT indexes and HH:MM:SS,mmm. The converter does not verify that end is later than start, sort cues, detect overlap, preserve a BOM, validate UTF-8, interpret styling, escape markup, enforce line length, or test playback. Extra commas in the time line are ignored after the second field. If no usable block remains it reports an error. Review timing, order, text, encoding, and player behavior before distribution.
