Video

• All videos with audio must include closed captions.
• Captions must be:
  • Accurate.
  • Synchronized with the audio.
  • Complete (including relevant sound effects such as laughter or applause).
• Auto-generated captions must be reviewed and corrected before publishing.

When is a transcript required?

• Audio-only content (podcasts, recorded interviews, voice recordings).
• Any media where captions are not possible or not present.

When is a transcript optional?

Videos that already include accurate closed captions.

Providing a transcript for video content is strongly recommended, even when captions exist, because transcripts:

• Improve accessibility for screen reader users.
• Allow users to scan content quickly.
• Improve searchability and comprehension.

Audio descriptions provide spoken explanations of important visual information for users who cannot see the video.

When are audio descriptions required?

Audio descriptions are required when important information is conveyed visually and is not otherwise accessible, including:

• Demonstrations or procedures.
• On-screen instructions or text.
• Charts, graphs, or diagrams.
• Slides or visuals not read aloud.

When are audio descriptions optional?

Audio descriptions are optional when meaningful visual content is explained verbally within the video or provided as equivalent text on the web page.

In many cases, audio description can be avoided by describing visuals naturally during narration.

Separate audio description tracks may be required if visual information cannot reasonably be described during the main audio.

Content must not flash or strobe more than three times per second to protect photosensitive users from seizures or disorientation.

• Avoid unnecessary animation, rapid transitions or zoom effects.
• Ensure high contrast between text and background.
• Use large, legible on-screen text.
• Allow adequate time for users to read content.
• Do not rely on color alone to convey meaning.
• Do not enable autostart for video embeds.
