Kaltura Capture allows you to record from two different video sources. It will place one video on top of another.
This is great if you want to show your screen and show yourself speaking. The viewer can switch the order of the video and adjust the location of the smaller video.
If you want to only show one video source make sure to turn off one of the video sources before you click the record button. Click one of the source icons which turns it grey. It will not record that source.
