Kaltura - How do I Add a Co-Publisher, Add a Co-Editor, or Change Owner
The owner of a Kaltura video can give other users permissions to edit their videos, permission to publish those videos into Canvas courses, or entirely transfer ownership of their videos to another user.
Add Co-Editor or Co-Publisher
Once you've given another user Co-Publishing rights to a video, they can insert it in Canvas (or elsewhere) by following the steps in: Kaltura - Inserting Videos in Canvas.
One you've given another user Co-Editor rights to a video, they can trim, clip, chop, or add quizzes to it by following the steps in: Kaltura Video Editing Tools - User Guide. They can also add or edit captions by following the steps in: Kaltura (Captioning) - Adding and Editing Captions.
For step-by-step instructions on transferring ownership of Kaltura videos, see Kaltura's Change Media Owner guide.
