Using the channel Wizard, an engine is automatically generated and added to the channel. But in situations where you would like to:

  • separate the video and the graphics playout 
  • set up a redundant engine
  • add several individual play out channels to a single just:live user interface

 a new engine has to be configured:

  1. To configure a new just:out engine, select a channel and activate the Layers & Engines tab.
  2. Click on Select engine… or click on an existing engine.
  3. In the menu, choose New engine to add a new engine.

an existing engine has to be configured:

  1. To configure an existing just:out engine, select a channel and activate the Layers & Engines tab.
  2. Click on an existing engine…
  3. and choose Configure engine.


A window with three tabs will appear, allowing you to define the engine attributes, define repositories and to configure the optional streaming output.

1 Network: Define how the new engine can be accessed via the network.

  • Name: type in a name for this engine, so you can identify the engine later.
  • IP address: type in the IP address of the machine which is running the remote just:out and the port which has been defined in the just:out preferences there.
  • just:control checkbox: activate this checkbox in case you use the just:control failover solution in a redundant environment. 

2 Video device & output: Select the hardware you'd like to use for the final output:

  • Screen: if there is no video hardware available for the final output on the machine running the just:out engine.
  • AJA: in case you have a Kona card or Io (XT or 4K) device from AJA installed on the machine running just:out.
  • Blackmagic: in case you have a Decklink card or UltraStudio device from Blackmagic installed on the machine running just:out.

Video buffer: Select a higher Video buffer if the data rate needed for playing the video and graphic files is high and/or the continuous data rate your storage system is able to deliver is low. If your storage system can deliver a very high continuous data rate and the data rate needed to play the video and graphics files is low, you can select a small video Buffer.

3 Audio Output: Configure the audio output here.

  • Maximum audio channels: allows you to specify the number of audio channels played out by the selected device. This is helpful if a third party audio device (or an encoder for example) does not support "empty" audio tracks.
  • Movie/live input delay: this is useful in case you have to adjust the AV synchronization because of a third party hardware which adds a delay to the video.

4 Apply new engine to: Define the layers the new engine will be assigned to.

  • Selected layer only
  • All non-assigned layers
  • All layers

Select the layers you would like the new engine assign to and click Apply to take over your selection or Cancel to close this window without saving the new engine.

Once the engine has been configured, (re)start the engine and assign it to the layers of a channel you would like to use the new engine.
