That is correct. You could also provide a way for them to hide the video.

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!

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...".

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!
