Screen Recording

Digital recording of computer desktop with audio narration a.k.a. Screencast

A screencast is essentially an audio-visual recording of what is happening on your computer screen. CIT offers Camtasia Relay and Ink2Go for you to create screen recordings.


Possible Uses

Screen recording can be used to record self-supporting lectures. You can display your presentation slides (or anything else that can be shown on screen) and record your narration. You can also do short video tutorials to talk about websites or show how a particular software is used.
