You must unlock the Just Control Configuration window and stop the channel(s) to be able to make any changes.

Failover (optional)

  • The network settings of the mac running Just Connect must include a valid Router and DNS setting, otherwise parts of the failover workflow will not work.

  • Blackmagic ATEM driver version ATEM Switchers 7.2 or higher must be used. No other version can be used.

Starting with Version 1.0 of just:live & just:play it was possible to configure a Redundant Playout. With Version 2.0 we have added the ability to configure an optional Failover in case the Primary Playout Engine fails. The failover control is based on the Engine's status and can be used in a fully Redundant setup, where a Primary and a Redundant Engine is available, but also for Channels where only a Primary Engine is available.

Supported Devices

All Devices/Presets which can be configured using the Events tab can be used in case a failover switch is executed. This includes the ability to control video routers, video switches (supports also the ATEM media player), start/stop of just:in, GPI triggers, mail notification and more.

Behavior of the failover control

In case the primary Just Out engine fails, the defined event presets will be executed and failover will switch to:

  • The Redundant Engine (if available). Refer to chapter 6. Setup Variants.

  • The Failover Signal (in case there is no Redundant Engine available) Refer to chapter 6. Setup Variants.

The Failover Signal can be:

  • An additional signal which is added to the failover hardware

  • An additional signal which is added to the Blackmagic ATEM Failover mixer or an image which is stored in one of the ATEM's Media Player.

Setting up failover control

Using v4.2 and higher, the failover control can be found under Events tab - Rules.

  1. Stop the desired Channel by deactivating the checkbox in front of it. Stopping a Channel will also stop the primary Just Out engine and therefore the final output in case no redundant engine is running.

  2. Select the Channel in the Devices & Channels list.

  3. Click on the Failover tab.

  4. Activate the checkbox right in front of Enable Failover Control.

  5. Click Add Events and add those events to the workflow, which you would like to be executed in case the Primary Engine or the Redundant Engine fails, or in case both engines are not running.

Workflow Status in the Playout User Interface

The status of the playout is also shown in the just:live/play user interface.
