Streaming View
This view displays the streaming on air status, including the broadcast data rate and the
cache status. You can also see what streaming platform you are currently broadcasting to as it is
displayed at the bottom of the view.
On Air Indicator Prior to recording, the on air status indicator will display 'off' to let you
‚
know the switcher is standing by and ready to broadcast. When streaming begins, the
indicator will display a bright red 'on air' status until streaming is stopped.
If there is an interruption during the stream, for example the internet connection speed becomes
too slow and the cache is depleted, the on air indicator will begin flashing.
Broadcast Data Rate The data rate is measured in megabits per second. For ATEM Mini
‚
Pro and Extreme switchers to broadcast 1080p60 video without losing frames, the data rate
needs to be approximately 5 to 7 Mb per second.
Cache Status The cache status displays the capacity of the switcher's built in memory
‚
buffer. The cache is a small amount of internal memory that continuously records and plays
the program output. It acts as a safety measure if the broadcast data rate decreases below
a level able to sustain video. The variable nature of the internet is mostly due to network
activity or wireless signal strength, so if the broadcast data rate decreases, the buffer data
will increase accordingly. If the connection speed becomes slow enough that it cannot
support the video stream, the cache will fill with video frames to compensate. However, once
the cache is 100% full, the video stream will be compromised, so you will want to avoid a full
cache where possible. You can do this by testing the connection speed when you set up
your stream. During a broadcast test, watch the cache display in the multiview. If the cache
frequently approaches 100%, choose a lower quality in the live stream settings.
Tethering status
The smartphone icon is displayed when ATEM Mini Pro or ATEM Mini
‚
Extreme is connected to the internet using mobile tethering. The icon will become red
when on air.
Recording View
If you are recording to external drives via USB-C, this view will display the current recording status.
