You must unlock the Configuration panel first to perform any changes.
Before proceeding, you must stop the Channel by deactivating the checkbox. Stopping the channel will also stop the Just Out Primary engine output, unless there is a Redundant engine available.
A Channel can “pass-thru” a live signal attached to its video device, or play out a Fill+Key signal. The functionality may differ, depending on the used video device. Please refer to the dedicated Chapter 5. Live Input Signal Handling (v.2025.x) for more information regarding this.
Activate Live Input
Stop the desired Channel by deactivating the checkbox in front of it. Stopping a Channel will also stop the Just Out engine and therefore the final output.
Select the Channel in the “Devices & Channels” list.
Click on the “Format” tab.
Select the desired method in the “Live Input” drop-down menu. The methods are explained below.
Activate the checkbox in front of the Channel to start it again and to take over the changes you just made.
Close the Just Control Configuration panel and drag the Channel from the “Connections” tab to the Multi viewer area.
Live Input Methods
Off: Select this setting for a simple video only playout server with no incoming signal attached or in case you would like to play out using Fill+Key. The default output is black.
On, default black: Select this setting in case there is a signal attached to the SDI input of the video device, that you would like to “pass-thru” to the available outputs while a live event is scheduled. The default output is black in case nothing is playing in the timeline.
On, default pass-thru: Select this setting in case there is a signal attached to the SDI input of the video device, which you would like to “pass-thru” to the available outputs while a live event is scheduled. The default output is the signal which is attached to the “SDI 1” input in case nothing is playing in the timeline.
The ability to switch to a live source is also available when using one of the available streaming formats.
Activate Fill+Key
Stop the desired Channel by deactivating the checkbox in front of it. Stopping a Channel will also stop the Just Out engine and therefore the final output.
Select the Channel in the “Devices & Channels” list.
Click on the “Format” tab.
Under Output Format select the Format you would like to use for your channel and make sure, to select RGBA instead of 8- or 10-Bit. This allows the engine to process and therefore to output the alpha channel information on a separate SDI output.
Activate the checkbox in front of the Channel to start it again and to take over the changes you just made.
Close the Just Control Configuration panel and drag the Channel from the “Connections” tab to the Multi viewer area.
