There are several ways to configure your chroma key.
This section will explain the two main methods:
• Defining a chroma key based on an automatically generated chroma key.
• Defining a chroma key based on an area selected on a playfield.

In both methods, you need to go through the following steps:
1. Creating an offside line.
2. Accessing the Chroma Key edit screen.
3. Generating the initial chroma key definition.
4. Saving the initial chroma key definition in a profile.
5. Opening the chroma key profile.
6. Refining the initial chroma key definition.
7. Saving the final chroma key definition in the loaded profile or in a new one.

In the Chroma Key edit screen, the F8 function allows you to toggle between the
chroma key layer (white/black display) and the representation of the final
incrustation on the video signal (color display).
It is recommended to:
• Use the chroma key layer to define the chroma key parameters from F1 to F6.
• Toggle to the final incrustation to refine the black level parameter (F7).
Note
If you cannot see the representation of the final incrustation, this means
you need the limits of your playfield could not be automatically validated.
You need to validate them manually. See the section 3.2.2 ‘How to
Validate the Playfield Limits’, on page 63.
