Chroma Trap Menu
The keyer Chroma Trap Menu allows you to turn on a chroma trap
for selected keyers and to select the filtering mode.
M/E SELECT and KEYER SELECT — Selects the effects system and
keyer to which subsequent menu selections apply.
CHROMA TRAP — Enables or disables the chroma trap for the
selected keyer. The filtering removes unwanted chroma from
video used for keying.
If you have a 068904-01 Keyer module four levels of chroma
filtering are available, as follows:
BS - HARD, BS - SOFT, LP - HARD, and LP - SOFT.
(BS = Band Stop; LP = Low Pass.)
BS - HARD is the default selection and is for keys that have
high frequency content. The other selections provide varying
degrees of softening of the key, and can reduce ringing on
hard key edges.
If you have a 068904-00 Keyer module, one level of chroma
filtering is provided, and the CHROMA TRAP choices are ON and
OFF.
