To Set Up a Split Key
A split key works on an Auto Select or Self Key that has been set up and you want to apply a different alpha to.
- Set up your key with the video source you want to use.
- Click Navigation Menu > Live Assist and select the key you want split.
- 
            Click the Key Fill or Key Alpha button and select the new source for the
               key.
            - Key Fill — select a different source for the key. This will change the alpha selection as well.
- Key Alpha — select a different alpha for the key. Selecting the different alpha creates the split key.
