An Accessibility Checklist for Video Content
Video content requires specific accessibility considerations that go beyond standard web page requirements. An accessibility checklist for video content addresses captions, audio descriptions, media player controls, and transcript availability. Organizations that publish video without accounting for these elements increase their legal risk under ADA Title III and may exclude users who rely on assistive technology.
| Key Point | What It Means |
|---|---|
| Captions | Synchronized text for all spoken dialogue, sound effects, and meaningful audio cues |
| Audio Descriptions | Narrated descriptions of visual content that is not conveyed through the existing audio track |
| Keyboard Operability | Every media player control must be reachable and operable without a mouse |
| Transcript | A text-based alternative that includes all dialogue, sound cues, and descriptions of visual information |
What Captions Require for WCAG Conformance
Captions need to include more than spoken words. WCAG 2.1 AA conformance at the Level A and AA levels requires synchronized captions that identify speakers, describe relevant sound effects, and note musical cues when they carry meaning.
Auto-generated captions from hosting platforms are a starting point, not a finished product. These captions frequently contain errors in timing, punctuation, speaker identification, and vocabulary. Reviewing and correcting auto-generated captions is a necessary step before publishing.
When Audio Descriptions Apply
Audio descriptions are required when a video conveys information visually that is not already present in the audio track. A presenter narrating slides while reading all on-screen text may not need an additional audio description track. A product demonstration that shows features without verbally explaining them does.
The distinction matters because audio descriptions require a separate production step. Knowing when they apply helps organizations plan video production more efficiently from the start.
Media Player Accessibility
The video player itself carries its own set of requirements. Play, pause, volume, full screen, and caption toggle controls all need to be operable through a keyboard alone. Screen reader users need to be able to identify each control and understand its current state.
Custom-built players often introduce accessibility issues that standard HTML5 video elements or well-established third-party players already address. Selecting a player with built-in accessibility support reduces remediation work later.
Transcripts as a Parallel Requirement
A transcript serves users who cannot access either the audio or the video. It also benefits users who prefer reading, who are in sound-sensitive environments, or who use search functionality to locate specific content within a video.
Transcripts should be published on the same page as the video or linked directly adjacent to it. They should include all dialogue, speaker identification, and descriptions of meaningful visual content.
Where This Fits in an ADA Risk Reduction Program
Video accessibility is one component of a broader accessibility checklist for organizational ADA risk reduction under Title III. An accessibility evaluation that includes video content reviews caption accuracy, audio description completeness, media player operability, and transcript availability alongside the rest of the site.
Addressing video content early in the production workflow costs less than remediating published content after the fact. Organizations publishing video regularly benefit from documented standards that content creators follow before upload.
