# Video has no captions

`a11y/video-caption` · severity **error** · category Accessibility · detected by `void a11y` and `void audit`

## Why it matters

Deaf and hard-of-hearing users miss everything said in a video without captions. Captions also serve anyone watching with the sound off.

## How to fix it

Provide captions with <track kind="captions"> or burned-in captions from the video host.

## Example

```
<video controls><source src="/demo.mp4"><track kind="captions" src="/demo.en.vtt" srclang="en" label="English"></video>
```
