Subject: playing video without audio
No previous message | Next message →
I'm hoping that I can get some direction on this. I was at a conference several years ago and I asked the question, "Does a video which does not contain audio and plays automatically produce an accessibility failure?" There was some deliberation among the group and the consensus was that 'yes' it was still a failure.
This question has come up again as "other places do it - why can't we". So this time I bring the question to this group of experts to see if the first group got it wrong or to see if they got it right.
Does an embedded video which does not contain audio and plays automatically produce an accessibility failure?
Thanks!

This is covered by WCAG SC 2.2.2, which states "For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it".
So your video is an automatic failure unless it is shorter than 5 seconds or there is a mechanism for the user to pause, stop, or hide it.
In case anyone tries to argue that the video is not "moving, blinking or scrolling information ", the "understanding" page says that "Common examples include motion pictures, synchronized media presentations, animations...".

Thanks for this, Steve. Just to make sure I'm reading Success Criterion 2.2.2 correctly. If we have a video (without audio) that plays automatically, if it lasts longer than five seconds, we need to include a way for the user to pause/stop the video. Is my understanding correct?
Thanks!

Under SC 2.2.2 You'd have to have controls to pause, stop, or hide it unless it's not played in conjunction with other content.

I like to give a little context on why such a thing is a failure. For people with attention issues, a moving image is a distraction that may repeatedly take their attention from the rest of the content. Imagine an annoying co-worker nudging you every few seconds to show you something on their smartphone whilst you're trying to work. They're not saying anything, just nudging you. You want a mechanism to stop them from doing that, or you want them to go away.
Cheers

Hi guys
Without knowing the content of the video..... Would it also not potentially fail if there's no alternative for the visuals, from an audio captioning/transcript point of view?

It possibly would need audio descriptions, not audio captions. Captions are
for hearing impairments, so since there's no audio, there's nothing to
caption. Audio descriptions are for people with visual impairments, since
there's no audio, it has no value to them. Depending on the specifics,
there may need an audio track or transcript provided.

If it's "video only" (no actual audio track at all), the simplest
approach (assuming the video does indeed convey information, and isn't
just "visual fluff/interest") would be a transcript, per
https://www.w3.org/TR/WCAG21/#audio-only-and-video-only-prerecorded.
Otherwise you have to start dealing with providing controls for the
audio in the page as well.

Thanks everyone â that's exactly what I was thinking, Patrick. The content of the video has yet to be determined, but I was envisioning providing a transcript as well.
Thanks!
