Realistic 3D replays

Viz Libero combines realistic looking 3D replays and advanced virtual graphics for sports broadcast. TV viewers will get unprecedented insight into controversial or tactically interesting sports scenes. Seamlessly combine eye-catching 3D replays with powerful dynamic telestration to analyse interesting or controversial scenes from the perfect perspective.

Based on the existing TV images only, Viz Libero generates arbitrary virtual camera images that appear deceptively realistic. It does not require any additional infrastructure in the stadium making it suitable not only for hassle-free remote productions but also for fully-featured studio applications. An interactive telestration and annotation system combines the full flexibility of Viz Libero's 3D scenes with an intuitive interactive user interface for TV experts.

Highly configurable

Viz Libero offers a wide range of 3D analysis tools that will bring your sports program to a new dimension. The setup is highly configurable and subject to individual preferences. Choose your feature packages for a customized solution that perfectly meets your production requirements and impresses your viewers.

Interactive shows

Give your experts the ultimate tool for illustrative sports analyses to make your highlight show even more dynamic. The interactive telestrator is available for all sports and is typically controlled via a touch-screen or an iPad. Empower your expert with an intuitive tool and increase the involvement of your viewers.

Content sponsoring

Embedding virtual advertisements into the generated content provides an excellent opportunity for your commercial partners to place their brand together with the 3D flights. Content sponsoring allows for the placement of tied-to-pitch advertising banners in a perspectively correct and unobtrusive way.


Automatic Player Tracking

Viz Libero’s Automatic Player Tracking is the first to automatically track players on the pitch and accurately show their movement without needing any special cameras installed at the stadium. By simply clicking on one or more players, Viz Libero automatically tracks them and corrects itself if the view of a player becomes obstructed at any point. This new function removes the need for keyframing players in post, meaning the graphic is ready to use within seconds. It can even be carried out from a broadcaster’s own studio, using Viz Libero and a direct satellite feed from the venue.

The Harvester - Bridging studio and remote

The Harvester is a component that enables studio access to multi-angle footage of a live production, seamlessly integrated with Viz Libero, Viz Engine, and Viz One in the broadcast center. The Harvester allows events to be logged of a sport game together with the desired camera angles – from the stands, the studio, or from home using a tablet or mobile device. Multi-angle footage will then be instantly encoded and transferred to the studio where it is directly ingested into Viz Libero for rapid and synchronized processing of 3D analysis. Multi-angle data can also be smoothly used by other Vizrt applications, such as Viz Engine for enhanced, multi-angle interactive highlights shows, or for archiving the multi-angle data with Viz One. As a one-box solution in a fully automatic workflow, the Harvester can be easily integrated into any existing OB truck.

Branded graphics, Sports Hub and Virtual Presenter

Set the stage for your next interactive and immersive sports studio shows by integrating Viz Libero with Viz Engine, Vizrt’s powerful render engine and real-time compositor of video and graphics. Together with Viz Artist, Vizrt’s 3D modeling and animation tool, this opens up unlimited possibilities for your sports program.

Branded graphics – Design your own customized and advanced graphics and animations with Viz Artist, making the Viz Libero graphics appearing even more advanced and with your own look-and-feel.

Sports hub - Your audience becomes part of the action with the Sports Hub. Use Viz Libero interactively with a touch screen or iPad as part of an interactive Vizrt scene, enabling your on-air talent to lead your audience through the sports highlights combining Viz Libero’s 3D analysis with other interactive elements like line-ups, statistics or tables. All templates and graphics can be branded with Viz Artist according to your preferences.

Virtual Presenter – Place your talent on the field with the players in a sports analysis clip. Viz Libero’s integration with the Viz Engine allows your talent to be part of the 3D analysis, and explain the game and tactics virtually, walking on the field amongst the players.
