By enabling and disabling certain sources to record, and depending on what you're presenting on the screen or via the webcam, you can create different types of recordings. These are a few different popular types and how you would achieve them.
Technical / Visual / Slideshow Presentation
If you want to explain visually how to do something on-screen, enable the Screen and Audio options, and disable the Camera option. While recording, you can demonstrate how to perform the actions on your screen while speaking and explaining the processes you're performing. This can be useful for showing how to navigate a website or use a computer application, and you can also record a PowerPoint presentation using this method. While recording, open your PowerPoint presentation as a full-screen slideshow and speak to each slide as you would if you were presenting in-class.
Another popular media type used is the "talking head" style video, which is the presenter speaking directly into camera and discussing a topic or explaining a process or idea. This can be done by enabling the Camera and Audio options, and disabling the Screen option.
Combined Presenter and Presentation (Picture in Picture)
If you enable all three input types during recording, viewers will be able to switch between the camera and screen as the main and "picture in picture" display, as in this example:
Note: this display is only possible if the video is embedded in the Text Editor using the Embed Kaltura Media button. Using the "Share" code for the video will not enable this interactive display.
A podcast is an audio-only recording. Enable the Audio source and disable the Screen and Camera sources. An audio-only piece of media is embedded in the text editor just as a video is, however just shows a black screen with a title.
