Using Keys

~If the key source resolution is greater than the output resolution, the DCS-200 only displays an area equal to the output resolution. This area can be positioned using the H Offset and V Offset fields on the Key Setup Menu.

~If the key source resolution is less than the output resolution, the key is centered in the middle of the screen. H Offset and V Offset can be used to position the key within the output active space.

Tip

Select the key source and adjust key parameters prior to your production. The key must be visible on Program in order to visually adjust clip, gain and opacity. Refer to the “Key Setup Menu” section on page 67 for details.

When the “Key Auto Take” function is OFF in the User Preference Menu, you must use the TAKE button to perform a “key” transition.

„Use the following steps to mix a key up or down, when Key Auto Take is OFF:

1.Press KEY. The button blinks to indicate that a “key’ transition is pending. If Menu Context is ON, the Key Setup Menu appears, enabling you to change the key source or adjust key properties.

2.Press TAKE. The system mixes the key up or down, at the current transition rate. Please note:

~If the transition is a “key up,” the KEY button lights solid when the key is fully on Program.

~If the transition is a “key down,” the KEY button automatically turns off when the key is fully off of Program.

Important

When Key Auto Take is OFF, if a source is pending, you will transition to the new source and add (or remove) the key when TAKE is pressed. Sources will flip-flop. If you do not want to transition to a new source, simply press the blinking source button to “un-pend” it.

~Refer to the “Key Transition Combinations” section on page 97 for descriptions of the many key combinations that can be performed with the DCS-200.
