Nicely laid out and good step-by-step explanations.  Bravo!

There are obviously many ways to get similar effects, usually with a trade-off between time and money, and the field of tools here is undergoing rapid innovation.  Getting comfortable with a few of them is probably well worth the investment for the 21st century educator.

Here are some other tools to consider:

1) Free: if you have access to a Smartboard:  If your school has Smartboards, you probably have a paid license for Smart Notebook suite of software, which comes with Smart Recorder, a super easy-to-use screencasting tool that produces WMV files (totally compatible with YouPD).  You can download Smart Notebook software here.  It has a 30 day free activation window and simply requires the product ID # from the back of your Smartboard to register.  No editing or webcam tools, but you can edit a WMV in Windows Movie Maver or just splice in your features or webcam shots as videos played during the course of your screencast.

2)  Cheap: Jing Pro costs meager $15 a year and allows you to record from your webcam and export as MPEG-4, though it doesn't have editing tools and it limits you to 5 minutes.  For the price, it's a very powerful option that makes hosting on Screencast.com a very easy, one-click process, which is handy if you don't have a video hosting solution for your course website.

3) Deluxe: Camtasia studio allows you to do it all in one pretty easy-to-use tool, and costs $170 for educators.  Because I consider video capture to be a big part of my blended learning strategy, I see Camtasia as a totally worthwhile investment in myself as a professional.    Conveniently, you always try it free for 30 days and decide for yourself, and then likely persuade your school to pay for it!
