Internal Video Sources
In addition to the SDI and HDMI inputs into the switcher, the switcher also has 8 internal sources that can
be used in a production. The internal source names are represented on the software control panel using a
long name. On the broadcast panel, a short name is used to represent the internal sources, and the labels
represent what the sources are, so they are easy to understand.
Black
Internally generated black is available as a source and can be used as a black matte in the production.
Color Bars
Internally generated color bars are available as a source. Color bars can be useful for verifying signals going
out of the switcher and can also be useful when setting up a chroma key with a vectorscope monitor.
Color Generators
ATEM has two color sources that can be customized to generate any color matt for use in the production.
Color sources can be used to add color borders for wipe transitions or as dip through colors for a dip
transition such as dip through white.
To adjust a color source on the software control panel, simply go to the color palette and click the color
chip, and the color picker will appear and you can select colors. On the broadcast panel, select color on the
system control, and adjust hue, saturation and luminance. It’s important to know that the deepest colors are
set at 50% luminance.
Media Players
The switcher has two media player sources, each has a fill and key (cut) output. Media player fill sources are
called media player 1 and media player 2, and two media player key sources are called media player 1 key
and media player 2 key.
The media player sources are used to play stills and clips from the media pool. The fill sources show the
color channels of the selected clip or still while the key sources show the black and white alpha channel of
the selected clip or still. Media players can be used in many parts of the production.
