WAVE Error

HTML5 video or audio

What It Means

A <video> or <audio> element is present.

Why It Matters

<video> defines video, such as a movie clip or other video streams. <audio> defines sound, such as music or other audio streams. Audio content must be presented in a text format to be fully accessible to users who are deaf and hard of hearing. Video content with audio must have synchronized captions and a transcript. Audio-only content must have a transcript.

What To Do

For video content with audio, ensure that synchronized captioning and a transcript is provided. For audio-only content, ensure that a transcript is provided.

The Algorithm... in English

A <video> or <audio> element is present. Note that WAVE does not analyze fall-back content within the <video> or <audio> element. This content should be accessible because it will be presented to the user if the video or audio content is not supported.
