Connecting Video Outputs
Video Outputs
There are multiple video outputs on your ATEM switcher which can be used to connect to
awide range of video equipment. ATEM Constellation 8K supports HD, Ultra HD and 8K.
ATEMProduction Studio 4K and Broadcast Studio 4K models include Ultra HD, HD and SD
viaSDI. HDMI is also supported on ATEM Production Studio 4K models. Descriptions of each
output connection are listed in this section.
It’s important to note that on ATEM Constellation 8K, the outputs are not dedicated with specific
labels like they are on other ATEM switchers and that’s because you can route any source to
them. For example, on an 8K production you may want the program output on output 1, a clean
feed on output 2 and route camera sources to the other 4 outputs for ISO recording. This gives
you more flexibility to switch any source to any output fast.
Plug in Ultra HD outputs via the 24 12G-SDI connectors on the rear panel. When the switcher
has 4320p set as the video format, the 24 connectors are automatically configured as 6 quad
link outputs.
SDI Program Output
This SDI output switches between Ultra HD, HD and SD. It outputs the main program video
output of your ATEM switcher and can be connected to any SDI based video device. The audio
on this output can use embedded HDMI and SDI audio from your cameras as well as external
audio via the switcher XLR inputs. ATEM Production Switcher models include a breakout cable
for external audio.
HDMI Program Output
Similar to the SDI program output, this output switches between Ultra HD, HD and SD. It outputs
the main program video output of the switcher and can be connected to televisions, video
projectors or even Blackmagic Design’s H.264 Encoder or HyperDeck disk recorders. The
audio on this output can use embedded HDMI and SDI audio from your cameras as well as
external audio via the switcher XLR inputs.
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.
