Char James Tanny put together a great list of resources on captioned videos. I wanted to capture it here so I could embed videos, share a few notes and post screen shots from YouTube.
They are examples showing how the following types of videos differ:
- no captions
- basic captions (built-in video)
- captions (turn on/off)
- audio descriptions
- ASL / sign-language
Only people with no visual or hearing impairments can enjoy a video without captions, transcripts, or audio descriptions.
Captions help those who cannot hear for any reason. They could be deaf or hard-of-hearing or they could work in a quiet or a noisy environment where they can’t listen.
Note: The problem with videos having built-in captions is they won’t show up on YouTube when searching for cc videos. This video does not appear in the search when filtering for cc videos.
Basic Captions (Turn on/off)
This one also has captions, but you need to click the CC symbol to turn them on. This gives the user control over closed-captions. This way you don’t have to create two separate videos. You create one video and let the user decide.
Transcripts display the words being spoken. In addition to the same benefits as captions, they also add search engine optimization benefits. (On YouTube, click Show More under the video to find the transcript.)
Audio descriptions further enhance the video by explaining what is happening. It’s like having someone read the script to the person who is listening. For example: [Gibbs slaps Tony on the back of the head.] Tony: Hey!
ASL / sign language
Videos with sign language are specifically designed for those who understand sign language. (Remember not all deaf and hard of hearing people know sign language. Yet most know English, so closed-captions can reach a broader audience.) YouTube has more than 40,000 ASL videos. The IRS has posted several videos to provide tax information.
To search for videos with captions:
- Enter a search term.
- Press Enter or Return.
- Select CC (closed caption) from the Filter drop-down menu.
This screen shot shows the result after filtering videos by cc. Notice the cc symbol in the entry. A video with built-in captions will most likely not make the cut or have the symbol like the example.
Google also allows you to filter for closed captioned videos.
