Add caption tracks to your video files

You can make your video content available to a larger audience when you add captions. If you want to reach deaf, hard-of-hearing viewers, or speakers of different languages, captions help these groups understand your videos.

You can use two types of caption files:

  • Caption file (recommended): This file contains the text and other information to time your captions with your video.
  • Transcript file: This file only contains the text. If you upload a transcript, the video player will have to determine when the words should be displayed. Transcript files take extra time to process and only work for English and Japanese.
Prepare your caption file

Although you can upload captions in any format, only SubRip (*.SRT) and SubViewer (*.SUB) are supported.

To help with readability:

  • Put descriptions like [music] or [laughter] inside square brackets to help people with hearing disabilities.
  • Add >> at the beginning of a new line to show the change of speaker.

You can find software to help you create these files or hire a company to make them for you. Learn how to create a caption and transcript files.
