Compositing the Picture
5. Adjust the degree of extraction.
Turn the [KEY-LEVEL] dial counterclockwise, toward [CHR KEY], to adjust the amount of extraction. At the center position, no
extraction at all occurs, and the background is not visible. Turning the dial counterclockwise all the way results in complete
extraction, and the foreground picture cannot be seen. Turn the dial to a position that yields an optimal degree of extraction.

6. Check the compositing results on the monitor.
At [MONITOR], press the [OUTPUT]. You can use the built-in monitor to check the results of compositing.
7. Remove the foreground picture.
Go to [COMPOSITION] and press the [KEY] button again to make it go dark. When it goes dark, the picture displayed in the
foreground disappears.
While compositing, no transition effect (MIX or WIPE) can be applied.
The duration of the fade during which the foreground picture appears or disappears is the time set for transition effects. By default, this is set at
0.5 seconds. You can use the menus to change the time. Go to the [VIDEO] menu, and at [TRANSITION], adjust the setting value for [TRANSITION
TIME]. Refer to “Menu Operations” (p. 44) and “VIDEO Menu” (p. 45).
If [PREVIOUS SELECT] is turn on, the unit automatically selects the channels previously assigned for background and foreground when the [KEY]
button is pressed again. Go to the [VIDEO] menu, and at [KEY], set [PREVIOUS SELECT] to [ON]. Refer to “VIDEO Menu” (p. 45).
