If IMAG (a live shot on the screen) is your goal, your computer isn't up to the task. Computers always have to do something to process the signal, and a desktop is not designed to do this quickly. The result is called latency or a delay on the screen. In other words, the congregation will see someone move on stage, and then see them move on the screen ? talk about distracting! If you are going to do IMAG, we recommend going with a high-quality switcher and good cameras to ensure the best possible signal to the projector.
On the other hand, if you want to use a live camera signal going to a computer for use as a motion background, there are some worship presentation software applications that can pull this off (make sure you check, some applications can't). Doing this well depends on whether the thing you're shooting is a focal point for the congregation. You can zoom in on a candle on the platform and keep it slightly out of focus to make a nice background. Even thought latency is still an issue, most people won't notice because they aren't focusing on that candle. If the latency is a distraction, you could just set up a table with a black cloth with your candles in a small room off the sanctuary.
To set it up, you'll need a camera and computer with ports for a firewire cable. You'll also need software that can accept an external video device as a background.
Latency is the critical element you have to keep in mind. If there is any doubt whether latency will be a distraction, don't run your camera through your computer. Wait until you get the right switcher.
Once you start using video backgrounds, be aware people in the church will start asking about IMAG. Even if it's just for baby dedications or baptisms to start, it's a good idea to start planning for a switcher now.
