Tips for publishing accessible video

Posted by: | Posted on: October 25, 2017

Over the last few months some of our Stamford crew have been talking about accessible video at Viocorp’s Multimedia Accessibility seminars (You can watch a webcast of one on Viocorp’s website). Video is a hot topic right now, with over 4 billion viewed on YouTube every day! That’s phenomenal! With numbers like that in mind, ensuring your video is produced and published in a way that everyone can access, is paramount.


So what does it mean to publish accessible video? Well, at first glance it sure can feel like a complex and tricky area. Especially in regards to WCAG 2.0 and understanding exactly what is required, at what level.

In our recent presentations, we went through the elements of accessible video, including some practical tips for how to do it. We finished off by showing how a video might look once you’ve made it accessible. We got some great feedback on this final slide, as it helped people see exactly what they had to do.

Here’s the “all together slide” that shows most common accessibility features of a published video.

The slide details what an accessible video looks like and what WCAG 2.0 level each feature applies to. Accessible video features include:

  • Transcript – an accurate text equivalent of the video (Level A)
  • Captions – text equivalent of the audio, superimposed and synchronized to the video (Level A and AA)
  • Sign language – Sign language equivalent in the appropriate sign language. For Australia that’s Auslang (Level AAA)
  • Audio description – a synchronized narrative that describes the visual details of the video (Level A, AA and AAA)
  • Contrast 7:1 – (Level A and AA)
  • Low background noise – (Level AAA)
  • No flashing – no flashing more than 3 times a second (Level A and AA)
  • No keyboard trap – on focus, the video player does not trap the keyboard focus (Level A)

This list is a great start for those who have video and need to retrofit some of these elements. But we’ve come to recognize there are a few things you can do before the video is produced, to make the whole process a little smoother and faster. We’re putting together a best practice video checklist, so you can consider these points from the start. If you’re interested in this and want to know when it’s ready for consumption, be sure to follow us on Twitter and I’ll tweet about it when it’s available.

For now I hope this post with the final results checklist, helps those of you who are publishing video and needed a helping hand.
