Provide Audio Description or Media Alternative for Prerecorded Videos
Ensure that prerecorded videos include audio descriptions or a media alternative so that people who are blind or cannot understand the visual content can access the information.
Acceptance Criteria
• Audio Description: Provide an audio track that describes the visual content of the video.
• Media Alternative: Offer an alternative form of media that conveys the same information as the video.
• Exceptions: An audio description or media alternative is not required if the video is a media alternative for text and is clearly labeled as such.
Examples
• Audio Description: A video includes a separate audio track that describes actions, settings, and visual elements for viewers who cannot see them.
• Media Alternative: A video has a detailed text description or a summarized document that covers the same information as the video.
Exceptions
• Media Alternatives: If the video serves as a media alternative for text and is clearly labeled as such, additional descriptions or alternatives are not necessary.
Tips
• Ensure audio descriptions are integrated seamlessly into the video, providing context and details without disrupting the viewing experience.
• For media alternatives, ensure the text or other formats effectively convey all visual information.
• Make sure that descriptions are clear and cover key visual elements and actions.
How to test?
1. Playback Check: Watch the video with the audio description to verify that it accurately describes the visual content.
2. Alternative Content Check: Review the media alternative (e.g., text description) to ensure it conveys the same information as the video.
3. Accessibility Check: Test with users who rely on audio descriptions or media alternatives to ensure they can fully understand the content.
