Press
{Type}
to display the
Key Type Pop-up
, which offers two options:
•
{Luma}
— Enables the
Luminance Key
mode, in which the hole-cutting
information is derived from the luminance (brightness) level of the key source.
•
{Linear}
— Enables the
Linear Key
mode, which allows the edges of anti-aliased
key sources (such as character generators) to be reproduced clearly. Two
separate signals are required from a linear key source: a cut and a fill. Refer to
the “
” section on page 210 for mapping details.

Note
When
Linear Key
mode is selected, the
{Key Fill}
button is
grayed out. This occurs because the linear key cut and fill
signals are pre-determined on the
Map Buttons Menu
.
