Re: playing video without audio

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...".
