Operating Your ATEM Switcher
If you’re in a hurry to get your graphics on air, then you can select to automatically copy this graphic to either
media player 1 or media player 2 after download. This lets you get images to air fast! If you don't want to
interfere with the media player graphic sources, simply select not to copy the media players to this graphic.
Pre Multiply Alpha should almost always be enabled and requires that you also switch on the Pre Multiplied
Key setting in ATEM Software Control or on the optional ATEM Broadcast Panel. Premultiplying mixes the
graphic color with its alpha channel when exporting to ensure your graphic has smooth edges which blend
in to the video.

Using Auxiliary Outputs
The ATEM 1 M/E and 2 M/E production switchers have auxiliary outputs which are spare SDI outputs that
can have various inputs and internal sources routed to them. They are very similar to router outputs, and all
video inputs, color generators, media players, program, preview and even color bars can be output.
If you want an extra program output, then aux outputs are perfect to use, or if you need a clean feed before
one or both of the down stream keyers, then you can even select these to the aux outputs. This would
give you a program feed without a logo or bug, so you can capture this as a broadcast master for later
transmission.
Aux outputs are extremely powerful, and can be routed on the software control panel, as well as the
hardware based broadcast panel. The aux output menus are available in the menu bar at the top of the
software control panel regardless of the tab currently selected so they are always available.
The switcher will always perform a clean switch when an auxiliary output changes sources so this means you
can use the switcher to cut between sources on the auxiliary output cleanly and without glitches.
Routing Auxiliary Outputs
On the ATEM software control each aux output has a menu for selecting the source to output on the aux
video output. Simply select the menu, and then scroll the list for the source you want to output. When
selected, the output on the selected aux will change immediately. You can see the current source with a tick
in the menu item.
On the ATEM broadcast panel the aux outputs are set from the aux menu in the system control.
Once the desired aux output is selected, you use the select bus to route the source to the aux
output. Because the broadcast panel uses the select bus, it's very fast to control aux outputs from the
broadcast panel.
Auxiliary outputs are assignable on the ATEM 2 M/E Broadcast Panel using the Destination bus. Once the
desired Aux is selected in the Destination bus, you can use the Select bus to assign an input to it.
Whatever video and audio is output on Aux 1 is also output on the USB 3.0 port.
