Video-as-Text-Alternative Never Labeled or Captioned

1.2.2 — Captions (Prerecorded)

Scenario

Setting

A project-management tool's task board

What’s wrong

A video that is meant as an alternative to on-page text isn't labeled as such, so it also isn't captioned and users don't know the text version exists.

Example

<video src="demo.mp4"></video>

Why it matters

Deaf and hard-of-hearing viewers, and anyone watching video without sound.

How to test

Find any video positioned as an alternative to page text: confirm it's labeled as such and check whether it's also captioned as required.

How to fix

Label the media clearly as an alternative to the adjacent text version.

<video src="demo.mp4">

  <track kind="captions" src="captions-en.vtt" srclang="en" label="English">

</video>

A <track> element with kind="captions" surfaces synchronized text for dialogue and important sounds.

Outcome

On a project-management tool's task board, this barrier is gone for deaf and hard-of-hearing viewers — they no longer have to work around this.
