About the just:live software components

• Just Out provides the final output (Virtual, SDI, or NDI®, SRT, UDP, ST-2110-Blackmagic Design DeckLink IP stream). It renders the frames in real-time either on the host GPU (Graphics) or CPU (video file decoding) and should never be quit during playout operations. For more information, please visit: 8. Just Out (v.2025.x)

• Just Connect acts like a channel manager, receiving and distributing all the information related to a playout channel. It interconnects to all Just Out engine(s) and Just Control user interface(s) which are related to a particular channel managed by Just Connect. For more information, please visit: 9. Just Connect (v.2025.x)

• Just Control: is the unified user interface for all ToolsOnAir applications. During the setup, the administrator can define which one of the two available solutions/user interfaces, namely just:live or just:play should be used for a specific channel. For more information about the just:play interface, please visit: just:play v.2025.x User Interface Manual

Add (“Drag & Drop”) the applications Just Out, Just Connect, and Just Control to your macOS Dock for faster access.

Configuring your just:play solution

IMPORTANT: Allow “Local Network” access in macOS Sequoia (15.x.)

The new Local Network Security feature in macOS Sequoia (15.x.x) enhances privacy and control by allowing users to manage which apps can access their local network. This feature addresses concerns over unmonitored network access, providing an extra layer of security by ensuring that only trusted applications have access to local network resources, such as printers, file-sharing devices, and other computers. In macOS Sequoia, users are prompted when an application attempts to access the local network for the first time, enabling them to allow or deny access (“System Settings → Privacy & Security → Local Network”).

When running the Just Out and Just Control applications for the first time on macOS Sequoia, you will be asked to allow it to discover and connect to devices or other applications on your network. Please click on the “Allow” button to ensure that the communication between the Just Out, Just Connect and Just Control applications is guaranteed.

Open

Initial setup

• Start the Just Out and Just Connect applications, review/agree the related End-User License Agreement (EULA) and confirm/apply all system-related requests (as described above).

• Start the Just Control application,review/agree the related End-User License Agreement (EULA) and confirm/apply all system-related requests. Once done, the Just Control application will automatically display the User Login window. We recommend keeping the defined username for now.

• Click on the “Login” button.

Open

• Once the Just Out and Just Connect applications have been launched (as described above), and you intend to run all applications on a single machine, ensure that you enter the IP address “127.0.0.1” and retain the default Channel Port Number (5000) before clicking the “Connect” button. This setup allows you to test and configure the system independently of your network infrastructure. For final production or On-Air use, we recommend using the dedicated IP address provided by your network administrator.

Open

Before the next step, verify that the option New Channel is selected, and enter the name of 
your Channel into the “New Channel” name field.

Open

• Next, select the Format you would like to use for broadcast (e.g., 1080p29.97 8 Bit) and make sure to select a 8bit mode in case the final output is NDI®, SRT or UDP.

• Then, select the option just:play for 24/7 scheduled playout to run the user interface for Master Control playout operations.

Change the Repository Folders if desired. The default Repositories are:

• Video files: “/Users/yourUserName/Videos”

• Graphic files: “/Users/yourUserName/Pictures”

• Audio files: “/Users/yourUserName/Music”

• Playlist files: “/Users/yourUserName/Documents/Playlists”

Selecting the “Include Simple FX layer with station and live bugs” checkbox automatically loads two predefined TOA Demo still images as Channel Station ID Bug and Live Input Bug. This feature can also be (de)activated after the initial setup, and the still images can be changed once the installation is done.

• Click the “Configure” button to complete the initial setup. The Just Control user interface should look similar to the picture below.

Open

• In the right sidebar, click on the Connections icon to show the Channel tabs interface.

Open

Verify that your Channel is operational

It may take some seconds before the Channel is running. To verify that your Channel is running, check the following status:

• In Just Connect the Status of the Channel should state “Playing”, with a  (Green) indicator.

Open

In the just:play interface, the Status should state “ONLINE” and the CTI (Current Time Indicator) should be (Green) (indicating the actual time). The timecode shows the actual time and changes constantly and fluently.
