Introduction

Government websites serve the entire public, including individuals with disabilities. Under ADA Title II, state and local government entities are legally required to ensure their online content is accessible to all users. The U.S. Department of Justice has made it clear that Web Content Accessibility Guidelines (WCAG) 2.1 are the key standard for compliance.

When it comes to video content, this means more than just adding captions. Audio description is a required component of accessibility and remains a common compliance gap on many government sites.

ViddyScribe helps government agencies address this challenge quickly, affordably, and at scale, making it much easier to meet both ADA Title II and WCAG 2.1 video requirements.


What Does ADA Title II and WCAG 2.1 Require for Video?

ADA Title II prohibits discrimination on the basis of disability by state and local governments. This requirement extends to digital content, including government websites.

The Department of Justice references WCAG 2.1 Level AA as the standard for accessible web content under Title II enforcement.

For video content, WCAG 2.1 requires:

  • Accurate captions for all spoken content and relevant sound cues. For prerecorded content, WCAG 2.1 Success Criterion 1.2.2 requires that“captions are provided for all prerecorded audio content in synchronized media, except when the media is a media alternative for text and is clearly labeled as such.”
  • Audio description for videos that convey essential visual information not available through audio alone. (See WCAG 2.1 Success Criterion 1.2.5.)
  • Delivery of video via an accessible video player that supports keyboard operation, works with assistive technologies, and allows users to control captions and audio description.
  • Sufficient color contrast for text and user interface components associated with the player and video. WCAG 2.1 builds onSuccess Criterion 1.4.3 (contrast of at least 4.5:1 for most text) andSuccess Criterion 1.4.11 (contrast of at least 3:1 for user interface components and meaningful graphics).
  • Control of flashing and visual effects in and around video content. Under WCAG 2.1Success Criterion 2.3.1, pages must not contain anything that flashes more than three times in any one second period, or flashes must remain below the general flash and red flash thresholds.

Many government agencies already caption their videos, but audio description is frequently overlooked or deprioritized, putting them at risk of non-compliance.


Common Challenges in Meeting These Standards

Government agencies face unique hurdles when trying to meet ADA Title II and WCAG 2.1 video requirements:

  • Limited budgets make it difficult to afford traditional manual audio description services.
  • High volumes of video content (public meetings, informational videos, training materials) make compliance seem daunting.
  • Lack of in-house expertise delays implementation.
  • Existing CMS and video platforms vary widely, so solutions must integrate flexibly.
  • Manual processes are too slow to keep pace with the constant publication of new video content.

That's where ViddyScribe comes in.

FAQ

What does WCAG 2.1 video compliance include?
The official WCAG 2.1 standard includes separate criteria for captions, audio description, keyboard access, assistive-technology-compatible controls, contrast, and flashing content. Which criteria apply depends on the content and the target conformance level.
How can government agencies add audio descriptions to videos?
Agencies can create descriptions manually, hire a professional service, or use ViddyScribe to generate audio-description tracks and VTT files that work with existing video platforms. Follow our audio-description workflow.
Who needs audio description, and when is it required under ADA Title II?
ADA Title II covers the services, programs, and activities of state and local governments, including public education. Under the DOJ's web accessibility rule, covered web content and mobile apps generally must meet WCAG 2.1 Level AA. Audio description is needed when prerecorded video conveys important visual information that its main audio does not already communicate; it is not automatically necessary for every video.
What files can I download, and which output should I use?

The available downloads depend on your description type and which processing steps you’ve completed:

  • Finished video: Your video with audio description incorporated. Use this when publishing a complete described version, including Extended AD.
  • Mixed audio track (Standard AD): The original soundtrack combined with audio description. Use this as an additional audio track on a compatible video platform.
  • Isolated AD audio (Standard AD): Only the generated description narration. Use this when mixing the narration yourself in an editing application.
  • Audio description script: The written descriptions and their timing, available in WebVTT format for review or further editing.
  • Closed captions: Caption files supplied separately from the video; they are not burned into the picture.
  • Descriptive transcript: A text version combining spoken content with visual descriptions, useful for readers who prefer to review the content at their own pace.

Text Only generation creates the script first. To download finished audio or video, complete the final generation step, then download your outputs from the Library.

Will ViddyScribe work with my current CMS, LMS, or video player?
Yes. ViddyScribe is platform-agnostic. Download VTT files or descriptive audio tracks for platforms that support them, or download an open-format MP4 with the audio description baked in and add it anywhere a regular video goes.
