Video Accessibility

Posted on in Work, WWW.

I’m working on a new web site that will be live for the next two or three years, hence I’m keeping an eye on both versions 1.0 and 2.0 of the WCAG guidelines. One of the things that has been requested is embedded videos (similar to YouTube) within relevant pages as opposed to having a standalone video section.

Thinking about embedded video meets accessibility and looking through WCAG 2.0 I’ve come up with the following:

To meet Priority One guidelines

  • Provide a full text based alternative to the video, i.e. a transcript plus a label explaining, more or less, “there’s a video and this is the transcript of it”.
  • Provide synchronised on screen captioning replicating the dialogure and important sounds in the video.

To meet Priority Two (our goal) guidelines

  • Provide synchronised audio description (noting changes of location, identifying speakers, etc.) in the gaps in the dialogue of the video.

To meet Priority Three guidelines

  • Provide an extended audio description that pauses the video in order to create room for extra information to be relayed aurally.

Does this agree with everyone else’s interpretation of the guidelines?

When I saw the trailers for yesterday’s episode of Primeval I wondered whether they were going to give any explanation of how the giant arthropods could survive in our atmosphere, and pleasantly they did – oxygen rich air leaking through the rift anomaly from the Carboniferous.

Then they go and spoil it by having the good looking bloke use a blowtorch right in front of the rift anomaly with no side effects what so ever. If the oxygen levels were high enough to affect the soldiers then wouldn’t any flames also be affected?

Oh, and they doubled the size of Arthropleura. There could be a larger species that simply hasn’t been found in the fossil record yet…

Science aside, it’s fun tea time nonsense, but the geek is very annoying and only Douglas Henshaw shows any signs of actually being able to act.

One last thing. We’ve all been conned. On the ITV web site for the series there’s a list of creatures. Have a look and see if you spot whats missing:

  • Coelurosauravus
  • Scutosaurus
  • Gorgonopsid
  • Giant Spiders
  • Arthropleura
  • Mosasaur
  • Hesperonis
  • Dodo
  • Parasite
  • Pteranodon
  • Agnurognathus
  • Predator

Not one of those is a dinosaur. No dinosaurs. Weren’t we promised dinosaurs? But all we get is arthropods, synapsids, and birds (I know birds are dinosaurs). Give us some proper dinos!
