> How Do I Make Subtitles And Closed Captions? [July 16, 2019]

Introduction

Many clients ask how us about subtitles. Generally, this is the first question a prospect asks us about our platform. In practise, they mean a few different things?

  • We want subtitles for our audio/video content.
  • We have subtitles, but want to make changes to the timing.
  • We want to embed our subtitles into our video file, for use in Social Media.

Let us look at these questions in detail.

What are subtitles or closed captions?

Subtitles are text derived from either a transcript or screenplay of the dialogue or commentary in films, television programs, video games, and the like, usually displayed at the bottom of the screen.

One of a series of subtitles, accessible through a decoder, is known as a ‘closed caption’. The term ‘closed’ is because the captions are not visible until activated by the viewer. On the other hand, ‘open’, ‘burned-in’, or ‘hard-coded’ captions are visible to all viewers.

What subtitle file formats exist?

The most common subtitle/closed caption file format used is *.srt. An SRT file (otherwise known as a SubRip Subtitle file) is a plain-text file that contains critical information regarding subtitles, including the start and end timecodes of your text to ensure your subtitles match your audio, and the sequential number of subtitles.

There are a large number of subtitles or closed captions formats available, see here and here for details.

How do I make my own subtitles?

  1. (Manual) Using a notepad tool, such as Notepad++, Sublime Text or your own computers default text editor, you can create your own SRT files.
  2. (Automatic) Use a video translator to transcribe your content using a Speech-To-Text AI which (a) automatically works out your captions, and (b) create the SRT file.

Remember: If you are using the AI, please check/edit the transcript after usage. Both text and timestamps can be edited in the platform.
