Richard Meagher, from Mt Lawley Senior High School, demonstrates how he uses Camtasia to create audio and video podcasts from PowerPoint Presentations. Camtasia is very similar to Movie Maker 2 (which is what I use to create my video podcasts) but is a bit more sophisticated, and slightly harder to use. The benefits of using Camtasia are you can create audio and video podcasts at the same time, and you can choose from a range of formats, most importantly you can save in m4a format that works on video ipods. If you want to know more about Camatasia check out it out at www.techsmith.com Richard has two podcast sites where he podcasts excellent audio and video podcasts on chemistry and physics using Camtasia (Chemistry - meagher's classes and physics - meagher's classes). Check out his podcasts they are really good.
