SRT (subtitle file)
A plain-text subtitle format: each block has a number, an in and out time and the text.
SRT (SubRip Text) is the most widely used subtitle format. It’s a text file with the .srt extension that almost every platform and video editor can read. Each subtitle has three parts: a number, the time range and one or two lines of text, separated from the next by a blank line.
An example block: “1”, then “00:00:01,000 --> 00:00:03,500” and then “Good morning, everyone.”. Note that the milliseconds come after a comma; that’s one of the differences from VTT.
SRT doesn’t store styles (colours, position) in a standard way: it’s deliberately simple. If you need the text to always look the same, even on social networks that don’t accept subtitle files, it’s better to burn them in.
Echo downloads SRT from the subtitle editor, one per language or all of them in a ZIP. You can try it free with the subtitle generator, and there are guides per platform, such as subtitles for YouTube.
