Kaltura Capture two-source (e.g. camera and screen) recordings can be trimmed and chopped in the Video Editor (Actions >Launch Editor), but sometimes you may want to edit in a video editing application like Adobe Premiere Rush, which is free to use for all UM staff and students. This video demonstrates editing two Capture recordings together using Premiere. Other video editing software applications can also be used to edit the two sources in a similar fashion.
