Primary and Secondary Video Settings

There are multiple options and choices for selecting recording inputs. For example, you may select to record a screen and camera or two cameras as inputs.  In the Kaltura Classroom Home Page, the default selection is the computer screen as the Primary Video and a camera as the Secondary Video. You can use the settings to configure the quality of recording, or choose a different recording input. To record only one input, you must define this input in the Primary Video settings and turn off the Secondary Video.
