Parametric media servers are utilized most fully in live theatre, which combines ambitious expression with last-minute direction as well as live control. While a theatre production uses video equipment by the week or month, a burgeoning number of churches are permanently installing systems. With a media server, a church can constantly stay creative and engaging with new content and effects every week. I did a number of permanent installs in churches and "mega churches." Typically a church has a lighting designer and a video producer who both take the training and learn to operate the system. Then the sky is the limit.
