All video and audio files uploaded to Kaltura My Media within Canvas or DU MediaSpace will have an auto-generated closed caption file. As the video owner or editor, you can edit the auto-generated closed captions to improve accuracy. Captions should be 95% accurate to meet ADA accessibility standards. This article describes how to edit captions. Auto-generator captions can take 10-60 minutes to be produced depending on the duration of your video or audio file.
