How to make an SRT file

SRT is the most basic of subtitle formats.

It consists of four parts:

1. A number indicating which subtitle it is in the sequence.

2. The time that the subtitle should appear on the screen, and then disappear.

3. The subtitle itself.

4. A blank line indicating the start of a new subtitle.



  • Name the .srt file the same as the video file you are providing subtitles for
  • Ensure the file is uploaded to the same directory as the video content
