Key Transitions
Key transitions are similar to background transitions.
You can perform key and background transitions
simultaneously.
Selecting Keys
Selecting a key allows you to configure the key type
and select a source for that key.
To select a key:
• Select a key by pressing one of the key select
buttons. You can choose from the following:
›AUTO SEL, or CHR KEY — selects Key 1 and
sets the key type.
›KEY 2 SEL — selects Key 2.
›KEY 3 SEL — selects Key 3 (KM-H 3000 only).
Note:
• If you select Key 1, you are selecting a key and key
type simultaneously.
Performing Key Transitions
Key transitions are performed similarly to background
transitions. All transition types are available for key
transition.
To perform a key transition:
1. Ensure the key you are using in the transition is
not on-air.
2. Select the key you wish to use.
3. Select the key type by pressing one of the
following:
•CHR KEY to create a Chroma Key.
•AUTO SELECT to create an Auto-Select Key.
4. Press the corresponding key button in the Next
Transition area to include the key in the
transition. You can choose from the following:
•KEY 1 to include Key 1.
•KEY 2 to include Key 2.
•KEY 3 to include Key 3 (KM-H3000 only).
5. Select a source on the Key/Aux bus that you
want to take on-air. The selected source appears
on your preview monitor over the background
image.
6. Choose the type of transition you wish to
perform:
• Press DISS to select a dissolve transition.
• Press WIPE to select a wipe transition.
7. Perform the transition by using one of the
following methods:
• Press CUT to immediately cut the selected
source on-air (selected transition type is
ignored).
• Press AUTO TRANS to have the switcher
perform a smooth transition.
• Move the Fader from one limit to the other to
perform a manual transition.
Note:
• To include multiple keys in the transition, push the
desired combination of KEY 1, KEY 2, and KEY 3
buttons simultaneously.
• When a key is on-air, the tally above the on-air key
glows red.
