"Do you mean to tell me that no one makes...?"
It's the company joke that a couple of our clients have very unique feature requests, and that they ask this exact question from time to time. "Do you mean to tell me that no one makes a [fill in the blank]?"
In the discovery phase of video system planning, we ask lots of questions. We find that some churches are concerned more about presentation of computer graphics (still images and motion backgrounds, along with file-based video), and others are focused on having live video as the primary source. Choosing one or the other makes it easier on us, but the more common answer is that our clients want both.
If you're using live video (cameras) for a typical event like a worship service, you have two audiences – the people who attend live, and the people who do not. And if you think about it, the needs of each group are very different. The live audience may not need to see the faces of those leading the event, but the audience watching your video stream or recording certainly does. How will you allow both to only see what they need to see?
Our challenge is finding a way to do both, and doing it well.
