Watch a video on Web Accessibility Perspectives: Video Captions from W3C Web Accessibility Initiative (WAI)

Accessible videos are a classic example of the universal design philosophy, which states that “what is essential for some, is almost always helpful for all. ” For example, videos with captions can help everyone when: 

• People are in noisy public environments such as airports, gyms, and restaurants.
• A person wants to watch a video while another person is sleeping or studying quietly.
• A speaker in the video has a strong or difficult to understand accent.
• A video includes specialised or unfamiliar vocabulary (legal, medical or scientific terms).
• A sound system is not working, or the sound quality is poor.
