How to add captions to videos

Why?

Adding captions to all videos should become standard practice in the UK for all organisations with a responsibility to provide an inclusive and accessible online/offline digital environment for visitors and users of content.  This includes videos embedded into websites, such as this one as well as video content displayed on television screens around the campus.  It also includes video resources that may be embedded into LearningSpace or part of a presentation.

The reason is twofold.

  1. This is now the law, as highlighted in the following article by Jisc
  2. We want an inclusive environment to allow everyone to be able to access our content

How?

There are a number of ways that you can create captions for you videos, this depends on whether you wish to capture ‘live’ captions or add captions after your video is captured.

  1. If you are interested in creating captions ‘live’, then you may wish to read a post about Otter.ai – this free-to-use software will enable you to capture audio ‘live’ with a mobile device or via the browser using a computer.  The software will capture speech and then process that into text, which can be downloaded.  You can then create a captioning file, which can be uploaded to your video via YouTube or Panopto for example.
  2. If you want to add captions to a video you’ve already captured then there are a number of ways to do this.  Microsoft Stream will automatically create captions on your videos, which you can then edit for accuracy.  You can then download and convert a file to make it usable for YouTube or Panopto.  There are other captioning solutions, but this post will guide you through using Microsoft Stream and Otter.ai.
