What is the File Extension SRT?
Ever watched a foreign movie with subtitles? Chances are, if you downloaded it, those subtitles were stored in an SRT file. The file format SRT, originally the output of the subtitle extraction program SubRip, is a widely accepted container for caption text and timing information. Commonly packaged with ripped DivX movies, SRT files can be read and created by a variety of programs or found online.

Background
-
With the advent of movie-"ripping" software, home-movie enthusiasts needed a way to extract subtitles. Along came SubRip, an optical character recognition (OCR) program that (with some training) could pull the subtitle text and timing information from a digital movie file and save it to a text file with the extension SRT. As media piracy grew in popularity, the subtitle format SRT spread along with it. It is now one of several "standard" subtitle types.
Features

SRT files are simply text files listing subtitle information: the number of the current subtitle, the start and end times when the subtitle should appear onscreen, and up to two lines of subtitle text. For example, the 17th and 18th subtitles starting about two and a half minutes into a film:
17
00:02:34,000-->00:02:37,500
He didn't see them [his family] for a year, so he's really excited.18
00:02:38,000-->00:02:41,500
He's really excited, he really missed them so he's very thrilled.The time format used is hours:minutes:seconds,milliseconds. Milliseconds are precise to three decimal places and use the French style of commas in place of a period. Since the SRT format is based on time instead of frames, subtitles must be customized to the movie file, which varies based on the source.

Function
-
When accompanying a media file, most media player programs will automatically recognize a subtitle file if they share the same name. If subtitles exist in several languages, it is common practice to append the language to the end of the file name, so that it will be easy to tell English from German with "Movie.eng.srt" and "Movie.ger.srt". In Media Player Classic (from the XP Codec Pack), for example, switch between subtitle "tracks" from the menu "Play / Filters / DirectVobSub".

Warning
-
Some media players require strict formatting for SRT files, such as a two-line limitation, no overlapping subtitles or a file size limit. To avoid loading errors, match subtitle file name to media file. Separate subtitle files (SRT) may not work in all DVD players when burned to a disc -- some DivX players can play AVI and SRT files.
