Rick has a Panasonic camcorder and would like to use it as a high quality webcam. Leo says that it depends on the camera. Most new ones are able to do it via HDMI. Some have live HDMI.
Rick needs is a live component or composite. It has to be able to pass the video stream out of the camera and into the PC. HDMI makes it easy. If it doesn't have that, then Leo says a capture card is likely needed. Also, camcorders will time out after a set time, so he'll have to turn that off in the settings or "pop" the cassette to keep it going. Firewire will work as it is always live.
