How to Make Background Videos Accessible

Background videos can enhance a webpage, but they must not interfere with usability or accessibility. To meet accessibility standards, background videos should support the main content and avoid causing distraction, confusion or discomfort.

Background Video Best Practices for Accessibility

Background videos must either not include sound or always be muted. Audio should never autoplay. Users should never be surprised by unexpected audio.

Motion and flashing should be minimal. Videos that flash more than three times per second can trigger seizures and must be avoided. Rapid movement, strobing effects or intense color changes can also cause discomfort and should not be used in background content.

Text placed over a background video must always remain readable. Use light or dark overlays to ensure sufficient contrast between the text and the moving background. Poor contrast can make content inaccessible to users with low vision. Read our article on Text and background contrast requirements for GSU webpages for more details.

Background videos should be short and simple, typically looping at 10–15 seconds. Shorter videos reduce distractions, lower bandwidth usage and help users with cognitive disabilities stay focused. Users must also have a way to pause or stop the motion if it becomes distracting or uncomfortable.

You can see the WordPress Row Settings for a background video from YouTube below. Don't forget to add a placeholder image in case the video doesn't load or a user's browser is set up to not play videos.

When Video Content Is Meaningful

If a background video provides important context rather than serving merely as decoration, additional accessibility steps are required. Text over video must meet a minimum contrast ratio of 4.5:1, and users who cannot view the video must be provided with alternatives such as a transcript or equivalent content.

Video files should also be optimized for performance. Large or poorly optimized videos can slow page loading and increase cognitive load, negatively affecting the user experience.

By following these practices, videos can enhance visual design while remaining accessible, usable and compliant with accessibility guidelines.
