Do not autoplay

Let people choose if they’re subjected to video content.

Autoplay can be very disruptive or hurt people

  • For people using a screen reader, it unexpectedly interferes with their ability to hear/control their machine
  • For people with cognitive differences, it can make it impossible to focus
  • For people with light sensitivity or vestibular disorders, some video content can cause illness

Is it ever okay?

  • Media with audio must absolutely never autoplay
  • Just because a video contains controls to stop the video doesn’t mean it’s okay to autoplay
  • Silent video can autoplay under these conditions:
    • It must stop after 5 seconds
    • The video features accessible controls
    • Autoplay is disabled when device reduce motion settings are activated

Annotations for video

  • It’s likely your developers will use an existing platform (like YouTube or Wistia) to deliver video content
  • Review the platform for accessibility with your developers
  • If the design calls for a custom video player, mirror annotations to follow conventions of existing platforms (like YouTube)
