Video is the best way to connect with most people and should be used whenever appropriate. But how can a normal person, working alone, make video that does a competent job of getting the message across in a semi-professional way?
Yes, used properly, a single person with a video camera can make quality footage under the right lighting and circumstances.
But too often the lighting just isn't happening. In this case, I have found a good solution in drag & drop style flash video.
Another related technology is "video screen capture."
Finally, there are the issues of how to actually get the video up and playing at your site.
