SubRip

SubRip is a free software program for Microsoft Windows which extracts subtitles and their timings from various video formats to a text file. It is released under the GNU GPL. Its subtitle format's file extension is .srt and is widely supported. Each .srt file is a human-readable file format where the subtitles are stored sequentially along with the timing information. Most subtitles distributed on the Internet are in this format.

ssa → const SubtitleType

SubStation Alpha

SubStation Alpha (or Sub Station Alpha), abbreviated SSA, is a subtitle file format created by CS Low (also known as Kotus) that allows for more advanced subtitles than the conventional SRT and similar formats. It is also the name of the popular, now discontinued tool used to edit subtitles.

ttml → const SubtitleType

Timed Text Markup Language

Timed Text Markup Language (TTML), previously referred to as Distribution Format Exchange Profile (DFXP), is an XML-based W3C standard for timed text in online media and was designed to be used for the purpose of authoring, transcoding or exchanging timed text information presently in use primarily for subtitling and captioning functions. TTML2, the second major revision of the language, was finalized on November 8, 2018. It has been adopted widely in the television industry, including by Society of Motion Picture and Television Engineers (SMPTE), European Broadcasting Union (EBU), ATSC, DVB, HbbTV and MPEG CMAF and several profiles and extensions for the language exist nowadays.

dfxp → const SubtitleType

Distribution Format Exchange Profile

Replaced with TTML

DFXP (Distribution Format Exchange Profile) is standard for XML captions and subtitles based on the TTML (Timed Text Markup Language) format, developed by the World Wide Web Consortium (W3C) in order to unify the increasingly divergent set of existing caption formats. TTML was intended to be a meta-standard, or sorts. It defines a set of requirements and capabilities that any other derived standard can incorporate, in part or in whole. Derived standards are called profiles. So, profiles are essentially groups of capabilities and requirements from the underlying TTML standard.

sbv → const SubtitleType

YouTube format .SBV

An SBV file is a file used to add subtitles or closed captions to a YouTube video. It contains a series of start and end timestamps paired with the captions to show during those time periods. SBV files are saved in a plain text format. SBV timestamps are formatted using the HH:MM:SS.

vtt → const SubtitleType

Web Video Text Track

WebVTT (Web Video Text Tracks) is a World Wide Web Consortium (W3C) standard for displaying timed text in connection with the HTML5 <track> element.

The early drafts of its specification were written by WHATWG in 2010 after discussions about what caption format should be supported by HTML5—the main options being the relatively mature, XML-based Timed Text Markup Language (TTML) or an entirely new but more lightweight standard based on the widely-used SubRip format. The final decision was for the new standard, initially called WebSRT (Web Subtitle Resource Tracks). It shared the .srt file extension and was broadly based on the SubRip format, though not fully compatible with it. The prospective format was later renamed WebVTT. In the January 13, 2011 version of the HTML5 Draft Report], the<track> tag was introduced and the specification was updated to document WebVTT cue text rendering rules. The WebVTT specification is still in draft stage but the basic features are already supported by all major browsers.
