# Audio/Video Accessibility Skill > **Canonical source**: `examples/AUDIO_VIDEO_ACCESSIBILITY_BEST_PRACTICES.md` in `mgifford/ACCESSIBILITY.md` > This skill is derived from that file. When in doubt, the example is authoritative. Apply these rules when implementing or reviewing any audio or video content. **Only load this skill if the project contains audio or video.** --- ## Core Mandate Accessible media provides equivalent access to speech, sound, visual information, and playback controls. The required alternatives depend on whether the media is audio-only, video-only, synchronized, prerecorded, or live. Plan captions, description, transcripts, and sign-language access **before production begins**. Use qualified human review — unreviewed automatic output is not an accessible final deliverable. Keep alternatives easy to find next to the media, and preserve them when media is embedded, translated, archived, or moved to another platform. --- ## Severity Scale (this skill) | Level | Meaning | | --- | --- | | **Critical** | Media content completely inaccessible to a disability group | | **Serious** | Access significantly impaired; workaround unreasonable to expect | | **Moderate** | Access degraded but partially available | | **Minor** | Best-practice gap; marginal impact on access | --- ## What the Media Requires (WCAG Level Matrix) The time-based media criteria are cumulative — Level AA includes applicable Level A requirements. | Media type | Level A | Level AA | L
