Admitting right up front my lack of tech sophistication, would anyone have the patience to shed some light on what I need for videocasts? I'm ready to shop for a new video camera. Ultimately, I would like to make videocasts of upholstery how-to's and other diy how-to's for web posting. That's about as much as I understand other than downloading to the computer and uploading to the internet. In a nutshell, what equipment do I need to have and what software, other than editing software?
