Unlike the img element, the video element doesn’t include an alt attribute for missing or inaccessible content. It seems to me that video is more likely to cause loading or accessibility problems than the humble image.

The note in the W3C Document Doesn’t make make clear a simple alternative.

Is there a recommended procedure for providing a suitable alternative text, or, say a link to a transcript?

As you pointed out, the tag <video> doesn't have an alt attribute.

I have two ideas to satisfy at least in part this need.

1) Adding a paragraph inside the <video> tag

<video> <source src="my-video-path.mp4" type="video/mp4"> <p>Description of the video...</p> </video>

2) Adding schema data

<video itemscope itemtype="http://schema.org/VideoObject"> <source src="my-video-path.mp4" type="video/mp4"> <meta itemprop="name" content="Name of the video"> <meta itemprop="description" content="Description of the video..."> <meta itemprop="duration" content="PT1M33S"> <meta itemprop="thumbnail" content="my-video-thumbnail-path.jpg"> </video> Share Improve this answer Follow edited Jan 17 at 9:39 ixany 5,99099 gold badges5151 silver badges7171 bronze badges answered Aug 27, 2020 at 10:38 Marco PanichiMarco Panichi 1,17911 gold badge2020 silver badges3131 bronze badges 1

• 7 Any non-<source> and non-<track> content inside the <video> tag should only be a replacement for the video and not supplemental to it — it’s only intended for browsers that don’t support the video element. (kindof like <noscript>.) The spec even says “this content is not intended to address accessibility concerns.” – chharvey Commented May 25, 2023 at 21:03
