Last week my boss approached me about a presentation she was putting together for a large audience. Her default play was to put together the typical Powerpoint slideshow which she planned to narrate.

Thankfully she has an open mind and I was able to introduce her to screencasts: simple videos that have the ability to show what is happening on the computer screen. They can be recorded in advance and some neat bells and whistles can be added. The best part is that many of these tools are free.
ScreenToaster

ScreenToaster is compatible with Windows, Mac OS X and Linux and is 100% Web-based. Simply approve a Java Applet to run and you can capture screen actions with a single click.
The keyboard command of ‘ALT + S’ will record/pause your presentation. Choose to record the full screen or designate a specific area, depending on what you are looking to illustrate.
Bonus features include the ability to add subtitles, an option to remove/replace audio and control over a screencap preview. Read more
