Enhancing the Game with LiveU Studio

Instant replay has become a crucial feature in sports broadcasting, offering fans and officials a way to review key moments in real-time. 

Key Features of Instant Replay in LiveU Studio

  1. Multi-Camera Angles

    • LiveU Studio allows for the integration of multiple camera feeds, enabling broadcasters to switch between different angles during an instant replay. This feature provides a comprehensive view of the action, ensuring that no detail is missed.

  2. Slow Motion Playback

    • One of the most critical aspects of instant replay is the ability to slow down footage to analyze fine details. LiveU Studio supports slow-motion playback, allowing for precise reviews of key moments like goals, fouls, or boundary line decisions.

  3. Seamless Integration with Live Broadcasts

    • LiveU Studio's instant replay feature integrates smoothly into live broadcasts. This means that replays can be quickly inserted into the live feed without disrupting the flow of the broadcast, keeping the audience engaged.

  4. User-Friendly Interface

    • The interface of LiveU Studio is designed to be intuitive, making it easy for operators to manage replays, switch camera angles, and adjust playback speed on the fly. This reduces the risk of errors and ensures that the replays are delivered smoothly to the audience.

  5. Cloud-Based Editing and Distribution

    • LiveU Studio's cloud capabilities allow for editing and distribution of instant replays in real-time. This means that content can be edited on the go and shared instantly across multiple platforms, enhancing the reach and immediacy of sports broadcasts.
  6. Framesync
  7. ISO Recording & Clipping
  8. Dedicated replay/clipping operator support
  9. Hardware integration with Contour Shuttle Pro V2

How create an instant replay?

  • Enable the Replay Option 

    • Start by accessing the settings panel for each input (camera feed) that you want to use for instant replays.
    • Within the settings panel (1), you will find an option labeled "Replay." (2) Make sure to enable this option for all inputs you want to display in the replay tab.

  • To ensure a perfect replay from multiple angles, make sure the Framesync option is enabled.

  • Begin the Testing Phase (3)

    • Once the replay option is enabled for your selected inputs, start the testing phase within LiveU Studio. This phase allows you to access the replay tab and ensure everything is set up correctly.

  • Add a Replay Player Input

    • Add a replay player input to your LiveU Studio setup. This input will be used to manage and display the replays during your broadcast.

Choose how many players/angles you want and assign them to live sources.

  • Start your live feeds

  • Open the Replay Player Tab

    • Navigate to the replay player tab within LiveU Studio. This tab provides a dedicated interface for managing your replays, including selecting which camera angles to use and adjusting playback settings.

  • Create Replays from Live Feeds

    • With the replay player tab open, use the interface to mark moments for replay, choose angles, and set playback speed.

You can also open it on the right or in a separated tab.

  • Once the replays are ready, they can be inserted seamlessly into your live broadcast using a cut or a transition.

Include audio during instant replays:

a) Enable ISO Recording on the desired live source(s)

  • Make sure ISO (isolated) recording is turned on for all camera feeds you may want to replay with audio.

b) Adjust the Mute Speed Threshold

  • Click the ⚙ Gear icon (top right) → go to the Replay section → then the Sound settings.
  • Find the field labeled “MUTE speed threshold”.
  • Enter a value less than 100%. This allows audio to come through when the replay is played at full speed (100%).

Behavior explanation:

  • If playback speed is equal to or less than the threshold value, the replay will be muted.
  • If playback speed is above the threshold, audio is audible in the replay.

Example scenarios:

  • If you set the threshold to 99%, then when you play back at 100%, audio is heard.
  • If you set it to 50%, audio will only play when the speed is between 51%–100% (i.e. anything above 50%).
  • If you leave it at 100%, the replay will always be muted (because the speed will never exceed the threshold).

Tip: Use a threshold just below 100% if you want audio under normal playback but still mute during slower/slomo replay.

If you have a dedicated Replay operator

The dedicated replay operator will be able to open the Replay panel in an external tab/monitor by opening the Replay section on the right -> Open in a separate tab.

The operator can now work on the Instant replays while retaining the producer as the decision-maker as to when to push what into the program.

Give the replay operator permission to push directly to PGM

  • Enable the "Take over preview" option in the replay settings in order for the replay operator to have control on the production preview from the external tab. (1 to 3)
    • Each time the operator is selecting an angle in the replay modal, the selected replay player will be selected in the Production preview.

  • Enable the "CTL" option (A) in order to be able to push directly instant replays into the PGM output using transitions.

Depending on your workflow you can use one/both or even none of these features.

 

If needed you can adjust the step value and the replay shortcuts from the settings panel (1) (in order to match with your hardware integration for example) -> Replay (2) -> change the settings (3).
