Hello everyone, Captions and audio descriptions are hard For some time now, I've felt there is a big problem with the requirements at level 1 of guideline 1.2. At the moment we require both captions and audio descriptions. That feels like a very tall order to me. Issue 1151 talks about scoping schemes that might help to cope with this but to me it feels strange that we would write guidelines for which we know even level 1 is so hard to achieve that websites that have multimedia content would almost have to use scoping to comply. Also, I have heard people say repeatedly that they do NOT want horizontal scoping, i.e. 'my entire website is accessible accept for the images'. Allowing horizontal scoping for multimedia feels inconsistent to me. Let's remember that a large portion of the web content out there is not made by professional companies with multimillion budgets for their websites. A lot of web content is made by individuals, non-profit organizations or small companies. With the growing bandwidth available, more of these websites will want to include multimedia. I predict that if they see WCAG requires them to do audio descriptions and captions, they will either choose not to follow WCAG or not use multimedia at all. Both cases will harm accessibility since multimedia is very helpful for people with cognitive disabilities. Another problem is that it takes professionals to create good captions and audio descriptions. If done by well-willing amateurs, chances are they will not produce anything that is usable for the people who need it. I think those people would be better served by a good textual description than by bad captions and audio descriptions or no multimedia at all. Real-world example Our company built software for entering information about the history of a village. The software itself publishes the information online on a website ( <http://www.erfgoedoverijssel.nl/> http://www.erfgoedoverijssel.nl, Dutch only). This software is being used by the local historical society where volunteers are entering documents about their village. The software allows them to attach images, video and audio files to the documents they are describing. For example: a 1945 film of the liberation of the village by Canadians. Since we want the website to be accessible, we had to think of a way to have the volunteers enter the metadata to make the multimedia accessible. Doing captions and audio descriptions was not an option, because there is no budget for training the volunteers, that's not what the volunteers signed up for and it would be costly to build it into the software. We decided to just have a title and a description field where volunteers can describe the multimedia in detail. In the website, the titles are used as the alternative for the multimedia and the description is available through a hyperlink (this information is also valued highly by visitors without special needs). At this point in time, the only type of media that has been entered is images (no multimedia). The website meets WCAG1 level AA and almost all of the AAA requirements as well. Now this is where it gets ugly: As soon as one of the volunteers adds a video, no WCAG conformance can be claimed at all anymore!! We drop from almost AAA to zero. But I really feel we did do everything we could to make the website accessible. My proposal To make WCAG2 a success, I really want level 1 to be feasible for all websites without having to use scoping. As a litmus test, I think all of our level 1 success criteria should be doable for non-professionals with limited time, skills and budget. For multimedia, I propose that at level 1 we just require a label and text description. The requirement for audio descriptions and captions would then move to level 2.
