Writing Audio Descriptions for Important Visual Content
Writing Audio Descriptions for Important Visual Content records a distinct W3C-supported accessibility writing task while keeping implementation mechanics outside the writing guidance.
Describe the important visual information that the existing audio does not convey, such as actions, scene changes, expressions, and necessary on-screen text.
Key details
Important caveats
Scope Boundary
Describe what is needed for understanding rather than narrating every visible detail; content already conveyed in the main audio does not need to be repeated.
Further guidance
Content
Write concise descriptions of the visual information that is necessary to understand what is happening, placing them where they can fit naturally around the existing audio.
Purpose
Purposeful description gives people who cannot see the video access to information that dialogue and sound alone do not communicate.
Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
