Using ATEM Software Control
The ATEM 2 M/E Production Switcher includes a built-in audio mixer that lets you use the embedded HDMI
and SDI audio from your cameras, media servers and other inputs without the need for an external audio
mixer. It also mixes audio from the switcher's built-in media players as well as external audio from the audio
breakout cable. This is perfect when using an ATEM 2 M/E Production Switcher on location or in small
spaces within modern OB vehicles as you don't have to find room for an external audio mixer. The audio
is mixed in the Audio tab of ATEM Software Control and output over the SDI and HDMI program outputs.
Mixed audio can also be output on the audio breakout cable and the audio mixer contains independant
controls for setting the audio level and also for selecting solo audio monitoring.
If you prefer to use an external audio mixer, it's easy to disable the audio for all inputs and you only need to
leave the external audio active in the audio mixer interface.
More information on how to use the audio mixer is included in the next sections.
Media Manager
The media manager allows you to upload graphics and image sequences to the media pool in the ATEM
switcher. Each ATEM switcher model has memory for graphics that’s called the media pool. This memory
varies in size between different ATEM models, and holds images with alpha channel that can be assigned to
a media player for use in the production. The ATEM Television Studio holds 20 still graphics with alpha and
the ATEM 1 M/E and 2 M/E hold 32 still graphics and 2 clips.
So for example you could have the maximum 32 still graphics and 2 clips loaded that will be used on your
live production and then assign each of the 2 media players to various stills as you work. As you take a
graphic off air, you can change the media player graphic to the next graphic you want, and then you can put
that media player back on air with the new graphic.
When a still or clip is loaded into the media pool, the alpha channel is loaded automatically if one is included
in the image. When a still or clip is loaded into a media player, the output of the media player will include
both key and fill outputs. If you select a media player as a key source, for example Media Player 1, both the
fill and the key are automatically selected so you don't have to select them separately. However the key can
still be routed separately so you can use a different key source if you wish.
