Definition
SRT Subtitles — SRT (SubRip Subtitle) is a plain-text subtitle file format. Each entry has a sequence number, a start and end timestamp in the form hours:minutes:seconds,milliseconds, and one or more lines of text. Because it is simple and widely supported, SRT works in almost every video player, editor and upload platform.
What an SRT file looks like
Open an .srt file in any text editor and you will see blocks like this, separated by blank lines:
- A number: 1, 2, 3 and so on, counting each subtitle.
- A time range: for example 00:01:02,500 --> 00:01:05,000, meaning the text shows from 1 minute 2.5 seconds to 1 minute 5 seconds.
- The text: one or two short lines of dialogue.
Note the comma before the milliseconds. The similar WebVTT format (.vtt) used by web players uses a period instead and adds a "WEBVTT" header line.
SRT vs other subtitle formats
| Format | Styling | Typical use |
|---|---|---|
| SRT | Minimal (some players read basic tags) | Universal sharing, editors, media players |
| WebVTT | Positioning and styling options | HTML5 web players and streaming |
| ASS/SSA | Rich fonts, colors and effects | Fansubs and karaoke, often inside MKV |
How to use an SRT file
- Side-by-side: give the subtitle file the same name as the video (movie.mp4 and movie.srt) in the same folder. VLC and many TV players load it automatically.
- Load manually: in VLC, use Subtitle, then Add Subtitle File.
- Editing apps: most editors can import SRT to place captions on the timeline.
- Translation and study: since it is plain text, you can read, search or translate it easily.
Why SRT matters when downloading videos
Many platforms store subtitles as text tracks, sometimes created by the uploader and sometimes generated automatically. Saving them as SRT gives you a transcript you can reuse, plus captions that work offline with the downloaded video. Subtitles burned into the picture (sometimes called open captions) are part of the image itself and cannot be extracted as text. See closed captions for the difference.
With SaveVidr's video subtitle downloader, paste a link and download the available languages as SRT. If no subtitles appear, the video has none published. Combine it with an MP4 download for offline viewing, and use subtitles only in ways the creator allows.

Frequently asked questions
How do I add an SRT file to a video?
Put it in the same folder with the same file name as the video, or load it through your player's subtitle menu, such as Subtitle then Add Subtitle File in VLC.
What is the difference between SRT and VTT?
Both are text subtitle formats; VTT is designed for web players and supports more styling, while SRT is simpler and works almost everywhere.
