5-6-2. Returning Key Menus to Default Settings
The key menus can be returned to their default settings by holding down the menu button for
the respective key. When the button is held down, a long beeping sound is made, and the
selected menu parameters are returned to their defaults. Holding down the KEY1, KEY2, or
KEY3 buttons returns all key menus to their default settings.
NOTE
In HVS-12ROUA, each keyer top menu has an INIT item that can return the keyer
menu to the default settings. Turn F6 to select an item to be set to default and then
press and hold down F6 for a while to return the menu to default.
5-6-3. Key Types
Three types of keyers are available: luminance, bus, and chroma keys.
Luminance keys
Luminance keys are also called a self key, and it uses the same video for the key source and
key insert. This is selected in KEY INSERT. The key insert/source signals can be selected
from the buttons in the AUX/KEY bus section. It can also be selected from the menu screen.
KEY1, KEY2, and KEY3 can all be created in the same way.
Bus keys
Bus keys use separate signals for the key insert and key source. To create a bus key, select
the KEY INSERT/KEY SOURCE signals in KEY-SOURCE/INSERT menu. Since the
operation for selecting the signal from the menu takes some time, the settings are first made
at the menu, and then the key link function is set to ON so that keys can be created by
selecting only key fill (insert) signals. Refer to section 5-6-5 and 5-6-6 for more details.
Chroma keys
Chroma keys use the difference in hue from the chroma component to create a key signal
and compose a separate video using the key. It is primarily used when composing images
with a person or other subject that is moving. For details about chromakeys, refer to section
5-10. “Chromakeys”.
