Multi View SDI and HDMI Output
The multi view outputs on all ATEM switchers are HD except for ATEM 4 M/E Broadcast Studio
4K, which are HD or Ultra HD, and ATEM Constellation 8K, which are HD, Ultra HD or 8K. You
can choose from a selection of multi view output formats and frame rates. This feature increases
compatibility with a wider range of monitors, plus you can output your multi view in Ultra HD
even if you are working in regular HD. Refer to the ‘using ATEM Software Control’ chapter, multi
view settings section for more information.
Some models of ATEM switchers include a single multi view, while bigger models include
2independent multi views so you can monitor more switcher sources. Each multi view includes
8 video input views, with preview and program views. ATEM Constellation 8K has four multi
view outputs for HD and Ultra HD viewing and one 8K multi view when the switcher is
in 8K mode.
Tally is included with red for sources on air, and green for preview. You can connect this output
to televisions and computer monitors with SDI or HDMI connections.
Down Converted SDI Program Output
Many ATEM 4 M/E Broadcast Studio 4K and ATEM2M/E Production Studio 4K models have a
dedicated HD-SDI program output.
Auxiliary SDI Outputs
ATEM switchers have auxiliary SDI connections that output the same video format in use.
The number of auxiliary outputs vary between models:
ATEM Production Studio 4K has 1 auxiliary output
ATEM 1 M/E Production Studio 4K has 3 auxiliary outputs
ATEM 2 M/E Production Studio 4K has 6 auxiliary outputs
ATEM 4 M/E Broadcast Studio 4K has 6 auxiliary outputs
Auxiliary outputs can use any internal and external video sources. For example, program feeds
if you need more program outputs, or clean feeds without down stream keying, or even specific
video inputs. Aux outputs are perfect for driving video screens on stage, or feeds where you
can independently control what the viewers see. Aux outputs switch cleanly and can be used
as cut only switchers independent of the main program outputs. The audio on these outputs is
embedded SDI program audio.
It’s important to note that all outputs on ATEM Constellation 8K can have any source routed to
them, which gives you the flexibility to use any output like it’s an aux output.
Preview SDI Output
On switchers with a preview output, this shows the source selected on the preview bus on the
switcher, as well as preview transitions. This output is perfect when you want to use a full
resolution preview monitor. Theaudio on this output is embedded SDI program audio.
M/E Output
ATEM 2 M/E Production Studio 4K and ATEM 4 M/E Broadcast Studio 4K have a dedicated SDI
preview output for M/E 1, as well as HD and Ultra HD SDI program outputs for M/Es 1 and 2.
These can be used as additional preview or program outputs for mix effects blocks 1 and 2.
ATEM 4 M/E Broadcast Studio 4K has 4 M/Es. M/E 3 and M/E 4 are typically routed back through
M/E 1 or 2 to create complex layered scenes. You can, also output a feed from M/E 3 or M/E 4
by assigning them to auxiliary SDI outputs.
