All videos produced in an educational environment or institution are federally mandated to comply with the Americans with Disabilities Act. Compliance with this act includes the captioning of video for the hearing impaired. This section offers several options for how to do this for videos produced in house.
Even if a video is not originally produced in VoiceThread, one can upload it to VoiceThread. It will auto-caption the video, you can edit the captions, then download the captions. Here are some links to assist you:

The Difference between Closed Captions and Subtitles
Although closed captions (CCs) and subtitles look similar, they’re designed for two different purposes. Subtitles provide a text alternative for the dialog of video footage – the spoken words of characters, narrators and other vocal participants. Closed captions, on the other hand, not only supplement for dialog but other relevant parts of the soundtrack – describing background noises, phones ringing and other audio cues that need describing.
Essentially, subtitles assume an audience can hear the audio, but need the dialog provided in text form as well. Meanwhile, closed captioning assumes an audience cannot hear the audio and needs a text description of what they would otherwise be hearing.
