I’ve just been looking for things that will enable us to liven up Powerpoint – and also video lectures. Powerpoint Producer is an add one for Powerpoint, which will allow you to integrate video and a powerpoint – so the video can be a “talking head” or could be other video to support the slides.
The download isn’t too large, if you have the bandwidth you can also get the Resources CD, with extra material, examples, tutorials etc on.
