This new closed captioning workflow known as e-Captioning involves making a proxy video from the non-linear system to import into a third-party non-linear closed captioning software. Once the closed captioning software project is completed, it must export a closed caption file compatible with the non-linear editing system.
According to Warner Bros. Discovery, the “Caption AI” workflow reduces caption file creation time up to 80% compared with manual captioning and cuts captioning costs by up to 50%.
A SAMI file provides closed caption support for multimedia formats. Generally, a multimedia file (such as a video or a sound file) is played by a media player such as Windows Media Player. Media players that support closed captioning and SAMI format may display the contents of the included SAMI file.

In British English, "subtitles" usually refers to subtitles for the deaf or hard-of-hearing (SDH); however, the term "SDH" is sometimes used when there is a need to make a ...
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 the 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 ...
Today, incompatible formats for captioning, subtitling and other forms of timed text are used on the Web. This means that when creating a SMIL presentation, the text portion often needs to be targeted to a particular playback environment. Moreover, the accessibility community relies heavily on captioning to make audiovisual content accessible.
The SubRip file format is described on the Matroska multimedia container format website as "perhaps the most basic of all subtitle formats." [18] SubRip (SubRip Text) files are named with the extension.srt, and contain formatted lines of plain text in groups separated by a blank line. Subtitles are numbered sequentially, starting at 1.
However, e-Captioning is now available to TV Broadcast facilities for tapeless workflows. Prior to the advent of e-Captioning, closed captioning was added to a video using a linear deck-to-deck process, which required the use of a physical master video tape, two tape decks (play and record), and a hardware closed captioning encoder.
