A mix-effects bank architecture of a video switcher having a plurality of video processing units; and an internal switcher routing matrix. The internal switcher routing matrix routing, a video source currently providing a video feed to an auxiliary output and a desired new source for the auxiliary output to a video processing unit that is not contributing towards video processing and routing an output of said video processing unit to said auxiliary output. The video processing unit that is not contributing towards video processing performs a transitional effect for the auxiliary output.

Generation of video transitions on an auxiliary bus using a video switcher

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 &ldquo;Trigger&rdquo; 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.

Linking external devices to switcher transitions

Linking keyers to background source selections is achieved by defining a key link association table between background sources and keyers for an M/E of a production switcher. Key Add and Key Drop modifiers are provided so that the effects of the key link association table may be modified while making a background source change.
