Auto Key Setup
An auto key allows you to associate a key alpha with a key video source in the switcher. When the video source is selected as a keyer, the key alpha is automatically used.
You must set a video source as an alpha before you can use it as an alpha for an auto select key.
Tip: You can associate one Media-Store channel as the alpha for another Media-Store channel. This means that if you load a
still that has alpha information in the file, the switcher uses the associated channel to load the alpha still.
