In our Web 2.0 times it seems like video sharing has become a social media giant. I can certainly see why - it’s exciting and novel to be able to transmit these magical moving images across time and space! Well, OK…if you put it that way, it’s not all that new. It is, however, spectacularly easy to do today — - and that is a major difference.
What isn’t so easy is to make these videos accessible. Video has a number of glaring accessibility problems. There’s nothing especially complicated about these issues — they should be obvious, after all — but accomplishing them at all seems to be beyond the pale at the moment. It’s not that it’s difficult to make video accessible. It’s not that the software to do it, at least in a limited manner, is expensive or difficult to use. It’s mostly two issues: laziness or ignorance.
What are the basic problems?
- The blind can’t see videos. Audio description of the events is required.
- The deaf can’t hear the audio tracks accompanying video. Text description of the audio content is required.
- Video content may feature flashing images or text: videos exhibiting these behaviors should carry warnings for individuals with epileptic photosensitivity or other related problems. (Not really the main focus of this article; but important to mention.)
I’m sure there are additional, more subtle issues that can be raised, as well, but if these three are dealt with we’ve accomplished the fundamental goals.
Why might people skip video accessibility?
The time involved in preparing transcripts and captioning can be substantial, and that may slow down some potential video creators. That’s laziness. I choose to believe that this is the lesser of the two issues: I’m optimistically hoping that most people who are aware of the accessibility issues and care about it will take the time and effort to make it happen. I think the awareness issue is far greater.
Some people will make the assumption that disabled populations won’t be interested in resources which feature aspects related to that person’s impairment. They are ignorant of what interest impaired populations may have in the aspects of that resource which they can access. A visually impaired person may never see you. Does this mean they won’t want to talk to you? No — just don’t expect pointing to be a useful to them. Pointing is a visual gesture: you need to provide audio description of your own actions in conversation. It’s the same in video. The visual elements may not convey any information to a person with a visual impairment, but appropriate audio description and the audio track may still convey all the information that person needs.
A lack of technological awareness is part of the problem: but I think that the greater issue is a lack of social awareness. Once a video resource creator can understand how important accessibility is, the technological barrier is minor. Information on captioning, audio description and transcribin is readily available.
I think I can understand when a site like YouTube fails to supply all of these accessibility options. The problem with user generated content in video is that the burden of responsibility for these accessibility features falls on the user. The average bedroom webcam self-recorder doesn’t have the knowledge or the capacity to prepare appropriate synchronized captioning or audio description.
But that doesn’t excuse it in other sites providing embedded video.
A few resources on Video Captioning:
- Steve Pugh: Video Accessibility
- University of Wisconsin at Madison: Accessibility Videos — A nice collection of videos on accessibility: transcripts provided and captioning included.
- WebAIM: Adding captioning in Quicktime
- WebAIM: Adding captioning in RealPlayer
- WebAIM: Adding captioning in Windows Media Player
- WebAIM: Video captioning software
- University of Washington: What is audio description?
- Joe Clark on Captioning
I think the biggest actual problem that comes up here is time.
We always talk about making it as easy as possible for someone to use a web site, we praise apps like Wordpress for making it easier for people to set up their own blog etc….
So we know people are kind of lazy, and though they may come out with things like ‘oh blind people aren’t our audience’ or whatever, but that’s mainly trying to justify the fact that they don’t want to add extra time and complexity to the process of adding video to a web site.
I think there’s a lot more chance of getting people to use accessible HTML code than there is to get them to create accessible content all the time.

That’s certainly one of the issues which slows people from retrofitting a site! It’s true; once the initial hurdle of discovering and learning accessible development methods is passed, the generalities of designing an accessible website are fairly minor.
Creating accessible content, once you’ve gone beyond plain HTML text, is a much more time consuming process — - and, specifically, it’s always going to be time consuming. You don’t learn how to do it then find it easy, because it’s not replacing a previous task. Making multimedia content accessible is an additive task to the other processes of content creation.
Thanks, Adrian!
