Requirements for Videos on Websites According to WCAG AA Level

The requirements for videos on websites according to WCAG AA level are well explained on the W3C website.

Further details can be found in the official WCAG article: WCAG Video Guidelines

They include, among other things:

• Subtitles for hearing-impaired users

• Audio descriptions for visually impaired users

• Controls for accessible user interaction

These measures ensure that videos are accessible to all users.

Does the content of videos have to be provided as a text summary? 

Yes, according to WCAG 1.2.1, an alternative must always be available for videos.

This alternative can be implemented in two ways:

• An audio track that adequately describes the content of the video
  or
• A text alternative via a transcription

Implementation in terms of accessibility is therefore desirable – even independently of the minimum legal requirements.
