Adjust the following parameters.

Adjusting the chroma key shadow

This function allows a shadow falling on the (typically blue) background color
to be rendered more realistically. Since portions of the (blue) background of
less than a certain luminance are treated as shadows, there is no effect on
cutting out of the foreground.
Use the following procedure.

1

In the Chroma Adjust menu, set [Shadow] on.

2

Adjust the following parameters.

Note

When chroma key shadow is on, key edge is changed to normal, and soft edge
is switched off.

Adjusting the video signal

You can change the gain of the foreground signal, or vary the Hue. There are
separate adjustments for the gain of the whole video signal, or Y and C
individually.
Use the following procedure.

1

In the Chroma Adjust menu, set [FRGD CCR] on.
