We’ve been testing and testing different ways to do screencasting. We’ve looked into different technologies, used different tools, and read about many different best practices. We tried Jing, used many resources at screencast.com, looked at what other higher-eds are doing, and evaluated where the industry is headed. Based on the information we’ve gathered, we’d like to contribute our piece of the pie as we are trying to create a screencasting repository for our community.
Focus
We can go into details in a future post about what tools we have decided to use for which application in the distribution of screencasts. For now, we’re going to show you what we do and how we do it. Then demonstrate an example.
