I recently bought Camtasia Studio 6, after previously using versions 5 and 3. It's a tool for screen recording (or screencasting, as some people like to call it). I use it for all my screen recording work, so I thought I'd do a quick video of how I use it. So, what you see below is a video of me making a video - which is kind of mind-boggling to do. To record me recording the screen with Camtasia I used Camstudio - a free screen recording app.
The video below just gives an idea of how you can use Camtasia to record your screen. I don't usually use any format other than flash for the web, but in this case I've encoded the video to wmv, just for the blog.
