There is also this great resource that provides lots of information about captioning video that is supported by the National Association of the Deaf.
Another point of information
I have long heard, and often preached that one of the advantages of captioning your videos was to improve SEO (Search Engine Optimization). What I had heard was that the search engines were able to spider through your caption file, index the content and add it to their inventory. Well that is not exactly correct. The big boys and girls – Google and Bing – do not index caption files. But the good news is that I have discovered a new service called 22frames.com that intends to do just that. Here’s how they describe themselves:
By continually indexing videos from these multiple hosts, this site offers an increasingly comprehensive catalog covering many different topics. Indexing is mostly automated using APIs and specialized web crawlers. User submissions of videos and channels also play an important role.
22frames is still in early development and there is no indication how many videos they have already indexed. Their technology sounds interesting and hopefully will be mainstream someday.
In closing, one of my upcoming blogs will discuss the inaccessibility of Flash video like YouTube for screen reader users. I’m working on that now.
