Autokeying method, system, and computer program product

Parallel automated keying allows multiple media productions to be keyed and outputted to a program or preview channel. An automation control system monitors and updates the operating states of a plurality of automated keyers, which support manual or automated production environments. A user interface allows a director, or other personnel, to set key attributes by selecting input sources for a background media production, a fill, and a key associated with the fill source. The operating states are monitored to select an unoccupied keyer. The three sources are selected and routed to the unoccupied keyer, which composites the sources on preview. Afterwards, the director steps or transitions the composite media production from preview to program. As a result, the director is not required to know which keyer is being used on-air to determine which keyer is available for a program channel.
