An audio engineer operates the microphones and mixes the sound, a technical director alternates between the different camera shots on the video switcher, and another engineer makes certain everything is running. After we've filmed a session, we know exactly where the speaker will point on a slide, so we can zoom in on it in the studio using the original slide. The home audience is not just watching a talking head. Using multiple cameras keeps the TV version lively by repeatedly shifting the viewer's attention from speaker to audience to overhead slide. Speakers are identified for TV viewers.
People change channels if a program moves too slowly.
And we get questions from viewers that may have a loved one who is going through something similar. A limited number of videotape copies are made for the department. We are planning future shows on such new research endeavors.
