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 to use in your units. These are a few different popular types and how you would achieve them.
Technical / Visual Demonstration
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.
Lecture Slides Presentation
You can make a pre-recorded lecturer easily by enabling the Screen and Audio options, and disabling the Camera option. While recording, you can run a PowerPoint presentation as a full-screen slideshow and speak to each slide just as you would in the classroom. This can be useful as a lecture replacement in online units, or for adding supplementary information to blended units.
Another popular media type used is the "talking head" style video, which is the tutor 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. This can be good for creating introductory videos to introduce yourself to your students, especially in online units.
Combined Presenter and Presentation (Picture in Picture)
If you enable all three input types during recording and embed this video in your LEO unit, 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 either added as a Kaltura Video Resource or embedded in the Text Editor using the Embed Kaltura Media button. Using the "Share" code will not allow 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 page just as a video is, however just shows a black screen with a title.
