If you are interested in learning about using videos in Blackboard, this is a recording of a workshop I did on using Kaltura. It gives you an overview of Kaltura and how it can help you avoid storage space issues in Blackboard. It also touches on Kaltura Quizzes and how they can be a way of having students interact with a video and for keeping track of how much of they video they have watched.
