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 TechSmith Relay (formerly 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.

User Testimonial

Assoc Prof Go Mei Lin, Department of Pharmacy
I teach a General Education Module which has a typical class size of 290 with students from varied backgrounds (Engineering, Science, Architecture, Business, Arts/Social Science) and in different years of study (1st to 4th year). One of the assignments given to the class is to prepare an audio-visual presentation on a given topic. This is an individual assignment and Ink2go is used for the recording of the presentation. Ink2go has been used for this purpose every academic year since 2011. At least a thousand students must have used it and the feedback has been largely positive. Students have found Ink2go easy to use and apply. This is significant given the differing technical competencies that would be expected from such a large cohort of students. The resulting output meets my expectations and I expect to continue with the use of Ink2go for this assignment.
