Key Signals - Sony MVS -8000X Quick Setup Manual

a 8000X you'll find inputs 1-144, if it's a 7000X you're find inputs 1-80). But you'll also find a lot of other
items like Color BKGD 1 and 2. You'll also find BLACK and WHITE (we'll get to WHITE later). If you have a
8000X, the Premium Inputs will be listed. Both the 7000X and 8000X will also have their Format
Converter input channels. Finally, you will find all the other internal signals, like PGM, ME PGM, etc.
that you may want to assign to a button. In a nutshell, if it's a signal that you want to punch up on the
main switcher or an aux bus, you'll find it on the right-hand source table.
So, let's assume you've wired a few inputs to IN01, IN02 and maybe IN03. By default those are going to
be set on V/K pair #2, 3 and 4, respectively.

Key Signals

Also notice that, by default, the associated key signal is the same as the video signal. If you have a CG or
some other device that has a key signal, we need to tell the switcher which input to use for video and
which one to use for its associated key signal. Find the video input name in the left table that
corresponds with where the video from your device is wired and make sure it's selected. In this
example, we'll simulate this on Input 7 and Input 8, which are called "CG|V" and "CG|KEY." Next press
the KEY button in the Assign group. Make sure only KEY is turned on, if both VIDEO and KEY are turned
on, turn off VIDEO. In the right table, please find the input you wired the KEY SIGNAL to. After you've
found and selected the key signal, please press the purple SET button. You should now see in the left
table the video coming from one input and they key coming from another input.
We've just set up a VIDEO/KEY pair. It is very likely that you will have "left-overs" in your left table. For
instance, if your video was input 7 and your key was input 8, you will likely still have a table entry that's
seems to be treating the key like it was its own line. That's ok and we can just leave it for now.
Normally, if a video signal had no associated key signal, like a camera, we wouldn't really care. That was
before the invention of internal Digital Effects (DME). Since the DME's video input is really the output of
