Kaltura is a resource that allows its user to employ the associated software from within the Canvas resource to easily record lectures in class, at home or on-the-go.  More information can be found HERE.

This resource can be used primarily by professors who have existing video files they want to upload into their Canvas course for students to view only in Canvas.

The latest version of the Resource also added the capability to do screen capture. While it's similar to Camtasia Studio, the produced videos cannot be edited or downloaded. They exist only on the Kaltura streaming server.
