How To Create an SRT File

This guide goes over how to create an SRT file for your video when you use text to speech software.

SRT file referes to "Subrip Subtitle", it's very easy to do for captioning video content. Here are step by step process:

Basic Understanding of SRT File Before Starting

SRT files are derived from the software SubRip, which “ripped” the extracted subtitles and associated timings from video content as a text file. The format is as follows:

hours:minutes:seconds, milliseconds --> hours:minutes:seconds, milliseconds

Every SRT file needs 4 components:

  • Number of the caption frame in sequence
  • Beginning and ending timecodes
  • Caption
  • Blank line indicating the start of a new caption sequence

Why this is so time consuming: You have to manually mark timestamp for the entire video to match all dialogue

4. Enter the caption in any language. Make sure to limit the caption to less than 32 characters with 2 lines per caption on the screen.

A good video should pace the viewer with the caption. Not too slow, not too fast.
