User's Manual

There are multiple ways to transition a key to the program output. The key can be cut on or off,
it can be mixed on or off, or it can be mixed along with a background transition. Upstream keys
are transitioned to the program output using the next transition controls. Downstream keyers
can be transitioned using their own transition buttons or by using the DSK TIE buttons to link
the transition with the main transition.
