This post contains support mateiral for the Screencasting workshop at the Edtech 2012 conference in NUI Maynooth. Thank you so much to my co-presenter of the workshop Damien Raftery from IT Carlow (@damienraftery)
A screencast is a digital movie in which the setting is partly or wholly a computer screen, and in which audionarration describes the on-screen action. It’s not a new idea. The screencaster’s tools—for video capture, editing, and production of compressed files—have long been used to market software products, and to train people in the use of those products. The term screencast compares with the related term screenshot; whereas screenshot is a picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, enhanced with audio narration.
There is an excellent chart available on wikipedia comparing the various software tools available for screencasting
