Doing Screencast

If you are an educator and do not want to spend a lot of money or your needs are basic, you can use a combination of a screen capturing program and video editing program to capture your computer screen as you do a live presentation with voice and then edit this video for distribution on video sharing sites like YouTube.

The combination that I recommend is SnagIt from http://www.techsmith.com and Windows Movie Maker (PC) and iMovie (Mac). The later two are free from Microsoft and Apple, respectively. SnagIt costs $50 while the others are free.

Below is a video showing you how to make a seamless transition from SnagIt to WMM.

If you plan to anymore fancy video editing, then there is a free program called Lightworks. It is on par with the commercial program Premiere by Adobe. There is a free and paid version of Lightworks, but Premiere is not free, even with the lite version called Premiere Elements.
