Abstract
An improved video production architecture adds an additional transition element for controlling external devices in synchronism with a given transition so that the transition is treated like a simple mix or wipe. The additional transition element is a “Trigger” function that has a value indicating when during the given transition the external device is activated. The trigger function, device controlled and trigger value are set up during preconfiguration of an effect in an effects memory. When the effect is recalled, if the Trigger function is activated on a switcher control panel, then the external device is activated at the time during the given transition specified by the trigger value.
