The web offers a world of quality videos for our enjoyment and enlightenment. However, for learners of English some videos can be difficult to understand. Captioned videos are an answer. The problem is they are generally scattered and/or mixed with all other videos across the Internet. Until now, there was no central place to easily and reliably search for captioned videos across multiple video hosts. 22frames was built, in part, to provide such a place.
Although not originally created with language learners in mind, 22frames now has an ESL section with videos which illustrate specific examples of idioms and slang.
COMMENTS
Opinions are divided as to whether captions are 'a good thing' or not for language learners, because, the argument goes, the tendency is to read the captions and not listen to what's being said. My own view is that if captions enable learners to enjoy DVDs or videos which they wouldn't otherwise understand, then that must be positive. In any case, you can usually turn them off if you want. On the other hand, watching DVDs or videos with foreign language subtitles is definitely not a good idea if you're trying to learn a language.
