Using Camtasia

I am experimenting with creating online tutorials, so I am trying to use Camtasia for screen capture and video. So far the results are not what I would want students to see, but I have only been working for an hour or so. I did record a powerpoint presentation with abysmal audio. When I manage to get it right, I can upload it and link it to my tapped in group on podcasting. Right now I have started a group, but there is nothing useful in it yet. I have a year of podcasting research ahead of me so it should get better as time goies on. Well, back to work.
