Making Video accessible to all

Making your videos as clear and as accessible as possible will allow you to reach a wider audience. The hints and tips detailed below are a guide on how to make your videos more accessible.

Think accessibility from the beginning

When filming and producing the video be aware of the accessibility features you may need to add.
For example

  • allow enough space for text on screen
  • use high-contrast colours
  • allow enough time for the content to remain on-screen so that it can be read

Make sure your video player is accessible

Video players can be inaccessible to some people with disabilities. They contain traps (where the keyboard focus stops inside the video and browser has to be closed). Some video players don’t support captions or audio descriptions which are essential for deaf and blind people respectively.

Turn off Auto-play

Video that play automatically as soon as the page loads can be disorienting to a number of disable people, especially for those with vision impairments using a screen reader, as they cannot hear their screen reader over the video.

Avoid flashing content

Flashing or strobing content can trigger epilepsy and migraines in susceptible individuals. Check your video with the Photo-sensitive Epilepsy Analysis Tool (PEAT).

Provide a transcript

As well as the dialogue, a transcript contain descriptions of the action or information on-screen. It should be provided in text, HTML or Word and placed/linked immediately after the video.

Provide captions

Not to be confused with subtitles, captions are a text version of the speech and sound on the video. They are displayed over the video, typically at the bottom, and are toggled on and off by the viewer through the video player. They let deaf and hard-of-hearing users follow the dialogue.

Captions should appear at the same time as the sound they are captioning and appear onscreen long enough to be read.

Subtitles are a direct translation of the speech (and the speech only) from one language to another. Subtitles do not include any other sounds that are in the video.

WikiHow has a step by step tutorial on how to upload captions to YouTube

Use audio descriptions

This is a spoken audio track played along with the video and it lets blind and vision-impaired users know what’s happening on the screen. It is important that this includes all visual information. These can be a bit tricky, and ideally should be taken into consideration during the production of the video, although “extended” audio descriptions can be used where the video itself pauses while the audio description plays.
