Simultaneously changing the background
and keys
You can change one or more of the four keys (downstream
keys on the PGM/PST bank) and the background at the
same time.

Selecting the transition type determines the way in which
the transition occurs. The following transition types are
available.
• Mix
• NAM (non-additive mix)
• Super mix
• Preset color mix (color matte)
• Wipe
• DME wipe
• Clip transition
• Cut
There are two modes of executing a transition: an auto
transition by button operation or a manual transition using
the fader lever. It is also possible to combine these two
modes.
Independent key transitions
In addition to common transitions, it is possible to carry
out independent transitions on the keyers of the M/E banks
and PGM/PST bank. These are called “independent key
transitions.”
By carrying out an independent key transition in
combination with a common transition, different transition
types can be used for the background and keys.
The following compares the independent key transition
with a common transition, taking a simultaneous change of
the background and key as an example.

Effect of a common transition
In the case shown in the previous illustration, carrying out
a common transition produces the following change in the
image.
Effect of a common transition
Effect with use of an independent key transition
The key is inserted with an independent key transition as
the background changes with a common transition,
providing the following result.
