HelpTube1 teaches you how to improve video quality when recording with Camtasia. The reason some videos don't have the HD version is that it takes 30-40 minutes for YouTube to verify whether the video is in high definition or not. In Camtasia 5 there is a Tools tab at the top of the program window. Click on that and then go to Capture. Check the box that says Save as AVI. Then go to Video, change Manual and change the frame rate to 80. Then click Ok and you will get these options every time. If you're using Camtasia 6, it's the same process.
