When media (video and audio files) are uploaded to Kaltura in Canvas and MediaSpace, they receive auto-generated closed captions and a transcript by scanning the audio for spoken English. Unless the captions and/or transcript are edited by a human, they do not meet disability accommodation requirements.
Using the steps below, Kaltura media owners and co-editors can download the auto-generated transcript Kaltura created for their media, edit it on their computer, then use a feature called Alignment to turn the edited transcript into new Closed Captions for the media.

There are two ways to locate your Kaltura media:
