What is FreeD and how to use it with your PTZ cameras

Feb. 26, 2024 - FreeD is a very simple protocol used to exchange camera tracking data. It was originally developed by BBC R&D and is now supported by a wide range of software including Unreal Engine, disguise, stYpe, Mo-Sys and Panasonic.

What is FreeD?

FreeD is a commonly used protocol that covers 8 axis of movement, sending; position, rotation and lens data through UDP packets over a network. FreeD has been incorporated into numerous camera systems and mounts, recently it has become more widely offered in PTZ cameras, such as the Panasonic AW-UE150, Sony BRC-X1000, and now the PTZOptics’ MOVE 4K. These PTZ cameras can now output FreeD data and are considered a cost-effective way to add tracking data to a virtual set or augmented reality experience.

FreeD Livelink Plugin Supports

  • 8 axis of data
  • X, Y, Z (Position)
  • Pan, Tilt, Roll (Rotation)
  • Focus, Zoom (Lens)

FreeD Supported Hardware

  • Stype
  • Ncam
  • MoSys
  • Panasonic
  • Sony
  • PTZOptics

Current FreeD Integrations

UNreal Engine

Unreal Engine is the world’s most open and advanced real-time 3D creation tool for photoreal visuals and immersive experiences.


Mo-Sys is an award-winning, world-renowned manufacturer of virtual production solutions & camera robotics for Film, HETV & Broadcast.


Optical camera tracking device for live broadcast and movie production.


Disguise is the industry-leading platform at the heart of the new era of visual experiences. One powerful integrated system to create the next generation of real-time spectacle from the world’s biggest live shows and most immersive xR broadcasts to the most ambitious virtual productions in one end-to-end workflow.

Use Cases

  • Augmented Reality (AR) in Broadcasting: FreeD technology is often used to integrate AR graphics into live broadcasts. This allows broadcasters to overlay virtual images, statistics, or animations onto the actual footage, enhancing the viewing experience.
  • Virtual Set Design: FreeD can be used in designing virtual sets. This is particularly useful in news and entertainment shows where backgrounds or environments can be digitally inserted in real-time.
  • Film and Television Production: In film and television, FreeD technology might be used for special effects, allowing for more complex and visually striking scenes that blend real and virtual elements seamlessly.
  • Event and Concert Visuals: FreeD can also be used in live events or concerts to create dynamic backgrounds or visual effects that interact with the live action on stage.
  • Sports Analysis and Training: Beyond broadcasting, FreeD can be employed for in-depth sports analysis and training, providing coaches and athletes with a detailed 360-degree view of performances.

Why Choose PTZOptics

  • Accessibility and Cost-Effectiveness: The PTZOptics MOVE 4K, being a more budget-friendly option, will likely attract a wider range of users who are interested in AR/VR production but are constrained by budget. This could include smaller broadcast studios, independent content creators, educational institutions, and small to medium-sized event companies.
  • Ease of Use and Versatility: PTZOptics is known for creating user-friendly camera systems and excellent support. The MOVE 4K with FreeD could appeal to users who want a simpler setup process and easy integration into existing production workflows. This could be particularly appealing in educational settings or smaller studios where technical resources are limited.
  • Market Response to Needs: The MOVE 4K’s entry into the FreeD space is a response to a market demand for more accessible, yet high-quality, AR/VR production tools. This could lead to a broader acceptance and use of these technologies across various sectors.


In summary, the future of the FreeD protocol will largely depend on how it evolves with technological advancements, its adoption and integration within the industry, and its ability to stay competitive against other emerging technologies. As the demand for more sophisticated AR/VR content grows, protocols like FreeD that facilitate such content creation will likely continue to play an important role.
