What is Screen Recording?
Screen Recording is a video capture of your computer desktop. To use an analogy: if a screenshot is like using a camera to take a photo of your desktop, then a screen recording is like using a camcorder to record a video of your desktop.
For example, you can show a presentation in Acrobat Reader or PowerPoint and start recording the desktop while you narrate. As the recording continues, you can switch to your web browser to show a website that you want to highlight while you continue talking. You can then switch back to the presentation and so forth.
