Even though the settings are nice and simple and you only need to select the service and a few
other options, there is an XML file that has additional settings that knowledgeable users could
take advantage of to add other streaming services and customize the streaming menu with low
level settings. Refer to the 'changing switcher settings/saving and restoring switcher settings'
section for more information on how to save and restore using an XML file.
Streaming and HyperDeck Quality Settings
The data rate used by the quality setting will change depending on the video standard
ATEM Mini Pro is running at. For example, if you select Streaming High quality and are running
at 1080p24 then it would use the 6 Mb/s data rate.
The data rates used on HyperDeck High are 45 to 70 Mb/s, the rates for HyperDeck Medium
are 25 to 45 Mb/s and the data rates used for HyperDeck Low are 12 to 20 Mb/s. The streaming
data rates are lower to allow for transmitting the data over the internet, so the data rate for
Streaming High is 6 to 9 Mb/s, the data rate for Streaming Medium is 4.5 to 7 Mb/s and the data
rate for Streaming Low is 3 to 4.5 Mb/s.
You will notice that each setting has 2 data rates mentioned. The lower number is used for the
lower frame rates of 24p, 25p and 30p, while the higher data rates are used when you are
running higher frame rates of 50p and 60p. It's also worth noting that the default setting for the
streaming quality is Streaming High 6 to 9 Mb/s, as this gives a very high quality streaming
channel, and the fairly good recording quality.
If you are not streaming, then you could just pick one of the HyperDeck quality settings.
These are the same quality as the settings in HyperDeck Studio Mini and are a good quality
data rate when you need broadcast quality recordings. However, with the latest software
released for HyperDeck Studio Mini, it will also play the lower quality streaming data rates.
