SDI Audio Channels 15 and 16

You may want to loop one of your ATEM's outputs to an input to achieve a desired effect.
In some cases this can cause a feedback loop in SDI audio channels 15 and 16. If this occurs,
you can mute SDI channels 15 and 16 by clicking the 'mute' checkbox in the audio options
located in the general switcher settings.
If you're using Blackmagic Design products for talkback, such as ATEM Talkback Converter 4K
and ATEM Camera Converters, muting SDI channels 15 and 16 from your switcher will not affect
talkback functionality.

Mix Minus Settings

On current ATEM Television Studio model switchers with built in control panels, the mix minus
settings on SDI outputs 5 to 8 let you mute the audio from their return program feed. This means
you can remove an input's audio from the program return feed if it becomes distracting.
For example, when doing live crosses there can be a delay in the audio which may be distracting
when the presenter can hear his or her own voice delayed on the program return feed. Enabling
mix minus for an input will output all program audio in the mix, minus that particular input.

Adjusting the Media Pool Clip Length

For models that support media clips, the media pool features two clips that share the same pool
of memory. By default, each clip receives half of the available memory which determines the
maximum number of frames. If you need a clip to be longer, adjust the balance of frames.
It's worth remembering that lengthening one clip will shorten the other.
