With HTML5 on the horizon
, it is becoming far easier to embed video on a web page than it has been. Sure, you can drop some code copied from YouTube, but you have little control over the HTML or the video output. Once you do have your video, you also need to bear in mind that not only are video (and audio) transcripts good practice, they are required by law for many organizations.

element. The caveat here is that you need to have a browser that supports the open Ogg Theora codec. You can check out the sample video
if you have such a capable and sweet browser.
YouTube Automatic Captions
Some of you may remember my post about how YouTube can now automatically caption
your videos using speech recognition software. While the results can be interesting, you can at least edit the captions coming out of YouTube. Terrill Thompson describes
how he grabbed the .sbv caption file from his video and updated it, then uploaded it back to YouTube for a much more useful result.
Shawn Henry leads the education and outreach effort promoting web accessibility at the W3C Web Accessibility Initiative (WAI). She recently wrote an article titled Transcripts on the Web: Getting people to your podcasts and videos
that explains why you would want to do this, some best practices, and even some resources. For example, in addition to supporting users who are deaf or hard of hearing, she points out that search engines can index a transcript where they cannot index a video or audio file. This adds to the overall SEO
strategy for any site. Her best practices go beyond what the captions mentioned above provide: she points out that sometimes we need to state how many people in a video raised their hands in response to a question. She is good to not browbeat the reader with a reminder that WCAG 1.0
, WCAG 2.0
and Section 508
all require transcripts — at least not until the end of the article.
