Kaltura: Remove Automatic Captions

When videos are uploaded to Kaltura in Canvas and MediaSpace, they are automatically captioned. This is done through the use of automatic speech recognition (ASR), which scans the audio track for spoken English. Media owners and co-editors can remove the automatic caption and associated files from a specific video in Kaltura.
