Screen "Casting"

Many people like the idea of creating a screencast for people learning new technologies.

Sue Waters has led a discussion over at Aquaculture WA, where one writer disputes the usefulness of this technique. Sue lists and compares some of the technology / strategies. The main goal of her colleagues was to upload powerpoint to the web, and have the voiceover work as well. Slideshare will show this kind of presentation on the web, but without audio.

: ideas for how to create and present :

What about a combination of slideshare for the powerpoint, and eg odeo for the Voiceover (odeo lets you embed individual mp3 files with a player, unlike podomatic which allows only the entire podcast to be embedded elsewhere). An example of this approach can be found eg. at Conversations in ACE. Double system could be confusing for presenters, but can be effective.

Software

Free or open source

One free screen recorder, CamStudio, would be worth trialling. (Has issues re size of output);
There's a free software called wink, which i think allows voiceover, and exports to Flash (though it could be a bit clunky).
There is a very new web-based screencasting tool called screen-cast-o-matic;

Here's Leigh Blackall giving a demo of how to use CamStudio (thanks Leigh):


Commercial

Capture Cam Pro is not free, but i've heard it recommended;
One crowd has taken the camStudio code, and created a commercial product;
Captivate, from Macromedia / Adobe, allows this kind of screen cast, with additional input from the viewer (so that viewing is active / interactive, rather than passive / memory).

Different Approaches

Someone known as "Common Craft" (a guy called Lee) put together this alternative kind of screen cast (as a video in BlipTV); an interesting way to represent screen elements with paper and scissors.
