Auto Select Keys
An Auto Select Key is a key in which two video signals
are required to make the key. The Alpha is used to cut
the hole in the video and the fill is used to fill the hole.
These signals often originate from external devices such
as character generators, external still stores, or other
graphics systems.
To Set Up an Auto Select Key
An auto select key is set up by selecting the keyer and
video source you want to use, and adjusting the key
parameters. The pairing of the video and alpha video
signals is done when configuring video inputs. Refer to
the Setup Guide that came with your switcher for
information on setting up Auto Keys.
Tip: You can return the clip and gain values to the default
settings by pressing the Make Linear knob.

Select the keyer that you want to set up an Auto
Select Key on.

want to use for the key.

Press AUTO SELECT.

Use the Clip knob to remove lower-saturated
colors from the video image.

Use the Gain knob to adjust the transition
between video image, and the parts of the video
image that are removed.

of the key from opaque (0%) to fully transparent

Use the Mask knob to apply a mask to the key.
The Auto Select key uses the pre-assigned Auto Key
association to select the proper video and alpha. If you
want to temporarily select a different video source for
the alpha, press and hold the AUTO SELECT button
and select the video source you want to use as the new
fill.
UltraChrome Chroma Key
An UltraChrome
™
Chroma Key is a key in which the
hole is cut based on a color value, or hue, rather than a
luminance value or alpha signal. The color is removed
and replaced with background video from another source.
The default color is blue.
Chroma Key adjustments are persistent and are not
affected by a soft reset or switcher reboot. However,
initializing the Chroma Key or performing a factory reset
returns all adjustments to default values.
Chroma Key Modes
The UltraChrome Chroma Key operates in one of two
modes, Basic or Advanced, depending on the complexity
of the Chroma Key you are setting up.
• Basic Mode — In basic mode, UltraChrome
provides a simple background/foreground chroma
key with adjustment for background spill and edge
softness.
• Advanced Mode — In advanced mode,
UltraChrome provides advanced background
shadow and translucency control, as well as control
over background/foreground transition areas.
Although it is possible to switch back and forth between
advanced and basic mode, the additional image correction
of the advanced mode is only applied in the advanced
mode. For example, if you use the basic mode to set up
the Chroma Key and then switch to the advanced mode,
the entire image may change as the image correctors
provided by the advanced mode are applied at their
default settings.
