Play out the program via SDI

mimoLive implements the Blackmagic Design API for playout to SDI or HDMI via Blackmagic Design hardware like Blackmagic Design DeckLink series.

Adding an SDI Playout Output Destination

Add a new SDI Playout Output Destination to your Output Destination list by clicking the + button on top of the list in the right most column of your mimoLive document. A popover window will appear with all the Output Destination options available. After double clicking the SDI Playout Output Destination icon a new instance will appear in the Output Destination list.

Setting Up the SDI Playout

The Start with show and Stop with show options define if the SDI playout should start and stop by the Start/Stop Show Button.

You can select a specific Audio Mix that will played out by via SDI. Please refer to Audio Mix Panel to learn more about setting up audio mixes.

Select the device you want to use from the Device popup.

The Video Format popup now shows all the available resolutions. Those options are depending on the connected Blackmagic Design hardware.

The Audio Format all available audio options. Those options are depending on the connected Blackmagic Design hardware.

Keying Mode

  • For devices with only one playout channel, the Keying Mode is non-functional.
  • For mimoLive Commercial or Broadcast license holders, it is possible to play out graphics and overlays including an alpha channel, so called key and fill signals, with the appropriate hardware. With this it is possible to supply an external switcher (with a built in keyer) with two signals and superimpose this over the program including transparencies. For this to work, use a dual channel device like the Blackmagic Design UltraStudio 4K (or better), or a Blackmagic Design Decklink 4K Extreme (or better) and select External as the keying mode. This will send two signals on the two SDI outputs: One for fill, one for key.

Playing Interlaced Video

mimoLive generally creates progressive video. If you want to play out interlaced video, make sure you follow this recipe:

  • Set up the mimoLive document to play the same frame rate your interlaced signal will be. For example use 50 fps if you want to play out 1080i50 or 60fps for 1080i60.
  • Set up the Output Destination to play out the format you want.
  • Make sure that you select “Display fill frame on video output” in the “When paused:” section of the video output setting in the “Blackmagic Desktop Video Setup”:

Supported Devices For SDI Playout

The following table shows the Blackmagic Devices supporting SDI playout with key and fill and the maximum video dimensions for keying (as per official Blackmagic Design SDK manual, March 2020):

These Blackmagic Design devices only play out single channel (Fill only):

  • DeckLink Mini Monitor
  • UltraStudio Mini Monitor
  • UltraStudio Express

This list may not be comprehensive. Please contact Boinx Support for information on unlisted devices.

Monitoring Live Performance

Once the Output Destination was toggled live its settings view is replaced by a status view displaying performance data in realtime. Refer to Monitoring Performance for details on performance monitoring in mimoLive.
