ETHODS AND

ECOMMENDATIONS FOR THE

HROMA

EFINITION

ETHODS

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.

TEPS

In both methods, you need to go through the following steps:

1. Accessing the Chroma Key edit screen.

2. Generating the initial chroma key definition
3. Opening a chroma key profile (and load the initial chroma key)

4. Refining the initial chroma key definition

5. Saving the final chroma key definition in a profile.

ECOMMENDATIONS AND

IPS

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 49.
