txt2sub.js - Text to Captions/Subtitle Conversion Library

txt2sub takes raw text as a string, and converts to a valid caption/subtitle format that will be understood by many subtitle editors, or non-linear editors.

Example: https://vodbox.github.io/txt2sub.js/

Supported Formats

Currently the only format supported for conversion is to the SRT timed text format.

Simple Usage

    var text = "Text can be on several lines\n"
             + "Line breaks separate individual captions.\n"
             + "\n"
             + "Empty lines are ignored by default.\n"
             + "Output will be valid SRT subtitles.";

    txt2srt(text);
