What is a .srt file?
File extension details and usage information
The SRT (SubRip Subtitle) file format is a plain text file format used to store subtitles for video content. It's one of the most basic and widely supported subtitle formats. SRT files contain sequential subtitle entries, each consisting of a numerical index, a timecode indicating when the subtitle should appear and disappear on screen, and the subtitle text itself. The timecode is typically formatted as HH:MM:SS,milliseconds (e.g., 00:00:10,500 --> 00:00:13,000). The subtitle text can span multiple lines and may include basic formatting tags, although support for these tags varies depending on the media player or software being used. SRT files are often distributed alongside video files and are loaded by media players to display subtitles during playback. They are easily created and edited using simple text editors, making them a popular choice for both professional and amateur subtitle creation. The simplicity and widespread compatibility of the SRT format have contributed to its enduring popularity in the world of video subtitling.
