Provide audio descriptions for all prerecorded videos.
Why it matters: Blind users need to hear descriptions of important visual details in videos.
Audio description is provided for all prerecorded video content in synchronized media.
What This Means: This success criterion requires that all prerecorded video content must have an audio description track. Audio descriptions narrate important visual information during natural pauses in the original audio, ensuring that blind users can understand visual elements that aren't mentioned in the dialogue or soundtrack.
Why It's Important: Videos contain visual information that's essential for understanding the content but may not be conveyed through audio alone. Actions, scene changes, on-screen text, facial expressions, and other visual cues are often critical to comprehension. Without audio descriptions, blind users miss this information, making the content incomplete or confusing.
Audio descriptions should be inserted during natural pauses in dialogue or soundtrack. They should describe all important visual information including actions, scene changes, on-screen text, character expressions, and other visual elements that contribute to understanding. The descriptions should be clear, concise, and synchronized with the video. They can be provided as a separate audio track that users can enable, or integrated into the main audio track.
This criterion ensures that blind users can access and understand the content, improving their overall experience and ability to use the website effectively.
This criterion ensures that users with low vision can access and understand the content, improving their overall experience and ability to use the website effectively.
Impact: When this criterion is properly implemented, it removes barriers for these user groups and creates a more inclusive web experience for everyone.
This success criterion benefits the following user groups:
Tip: Use this checklist during development and testing to ensure all requirements for 1.2.5 Audio Description (Prerecorded) are met. Check off items as you complete them.
Note: These are official W3C resources for 1.2.5. For the most up-to-date information and detailed technical guidance, always refer to the official W3C documentation.
Implementing 1.2.5 Audio Description (Prerecorded) correctly requires understanding your specific context. Code solutions vary significantly based on multiple factors:
HTML, React, Vue, Angular, PHP, Python, and other frameworks each have different patterns and best practices.
Server-side rendering, client-side rendering, static generation, and hybrid approaches require different solutions.
Your existing components, styling approach, and UI library influence how accessibility must be implemented.
Your specific user base, content type, and interaction patterns determine the most appropriate implementation.
We provide tailored implementation guidance by analyzing your specific technology stack, coding patterns, design system, and project requirements. Our team reviews your codebase and provides custom solutions that integrate seamlessly with your existing architecture.
