Self Keys
A Self Key is a key in which the luminance, or
brightness, values of the key source are used as the alpha
for the key.
Tip:
To select a Self Key on the C10 control panel you must
press the AUTO SELECT button. The Auto Select key defaults
to a Self Key when there is no alpha associated to the video
source. If there is an alpha associated to the video source, you
must press and hold the AUTO SELECT button and press the
source button again, like you were setting up a Split Key.

A self key is set up by selecting the keyer and video

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.
