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. The screenshots below illustrate how to edit captions in My Media within Canvas and the process is very similar within DU MediaSpace.
