what is an srt file

An SRT file, or SubRip Subtitle file, is a plain text file that contains critical information regarding subtitles, including the text of the subtitles in sequence, along with the start and end timecodes. It is one of the most popular subtitle file formats for video content and is used to add captions and subtitles to videos. SRT files are compatible with virtually all platforms and players, including Facebook, YouTube, Windows Media Player, and many more. A single file can also be used across multiple platforms. SRT files do not contain any video or audio content and must work together with the video for the final product.
