Provide Captions for Prerecorded Media
Ensure that all prerecorded videos include captions so that people who are deaf or hard of hearing can understand the audio content.
Acceptance Criteria
• Captions Required: Provide captions for all prerecorded video content that includes audio.
Examples
• Good: A video with spoken dialogue includes captions that display the text of the dialogue synchronized with the video.
• Bad: A video without captions, where spoken content is not accessible to viewers who are deaf or hard of hearing.
Exceptions
• Media Alternatives: If the video is an alternative to text content and is clearly labeled, captions are not necessary.
Tips
• Ensure captions are synchronized accurately with the audio.
• Include not only dialogue but also relevant sounds (e.g., [applause], [music playing]).
• Use high-contrast text for readability.
How to test?
1. Playback Check: Watch the video with captions to verify they accurately reflect the spoken content and are synchronized with the audio.
2. Accessibility Check: Ensure that captions are visible and readable, and that they include all relevant audio information.
3. Device Testing: Test on different devices and media players to ensure captions work consistently across platforms.
