The multi view output on ATEM Constellation 8K supports four 4K Ultra HD or HD outputs or
one 8K output up to 4320p59.94 so you can monitor at higher quality when you connect an 8K
monitor or television. ATEM 4M/E Broadcast Studio 4K supports up to 2160p59.94. If you set
your ATEM to 2160p50 or 2160p59.94 video, the multi view will be automatically displayed
using 2160p25 or 2160p29.97 respectively so you can use a wider range of Ultra HD
televisions. However if you want to use a standard HD television, then you can also set the multi
view outputs to be down converted to HD for even greater monitor compatibility.
For example if your ATEM is selected to run at 2160p59.94 then the multi view will output at
2160p29.97 when the multi view setting is selected to Ultra HD, or you can choose to output
1080i59.94, 1080p29.97 or 1080p59.94 when the multi view output is selected to regular HD.
Set Multi View video standard
For all other switcher models the multi view output is always HD even when running in standard
definition so you can see all your sources in higher resolution. When switching Ultra HD video
at 59.94 or 50 frames per second, the multi view will display HD video at 29.97 or 25 frames
per second respectively.
Setting the Down Converter Outputs
When running ATEM Production Studio 4K models in Ultra HD, the HD-SDI program output
always outputs down converted high definition 1080i video for connection to HD-SDI
equipment. High definition or standard definition video inputs are always output as HD or
SD video respectively.
ATEM 4 M/E Broadcast Studio 4K has 1 down converted program output that will
default to 1080p29.97 when switching Ultra HD video at 2160p59.94, or 1080p25
when switching 2160p50.
When running the ATEM 1 M/E and 2 M/E production switchers in high definition, the HD signal
is permanently down converted to SD via SDI and composite video outputs for connection to
older devices. 720p50 and 1080i50 down converts to 625i50 PAL. 720p59.94 and 1080i59.94
down converts to 525i59.94 NTSC.
Down conversion provides the following aspect ratios:
Center Cut Crop left and right side making a 4:3 image.
Letterbox Scales the video down with black bars to top and bottom.
Horizontal scale (squeeze) to make 16:9 image fit 4:3. Requires an anamorphic or
Anamorphic
16:9 monitor or television to correct the aspect ratio.
