Mo-Sys camera tracking systems for Virtual Production, VFX and live broadcast combine ‘absolute’ marker-based tracking (StarTracker), vSLAM support solutions, and precision encoder technology to deliver accurate, real-time tracking. Supporting AR graphics workflows and in-camera VFX, these real-time tracking systems integrate seamlessly with render engines, LED volumes, and studio pipelines. Built for reliability and scalability, Mo-Sys solutions ensure consistent, high-quality camera tracking across virtual studios and live production environments.
Yes, the same StarTracker tracking technology used for LED volumes also supports green screen virtual production. In a greenscreen virtual production setup, camera tracking data tells the compositing software how to move and scale the digital background to match the live camera, so the composite holds together even as the camera pans, tilts, or moves through the space. Mo-Sys tracking works the same way whether the final output is composited live or displayed on an LED wall, giving productions flexibility to choose the workflow that fits their space and budget.
Yes, Mo-Sys camera tracking is used well beyond live broadcast, supporting film, commercials, and other VFX-heavy productions. Recorded StarTracker data can be exported with an FBX file for use in Maya and other post-production tools, giving visual effects teams accurate camera and lens data to match CG elements to the plate. This makes Mo-Sys tracking useful both for real-time, on-set visualisation and for traditional post-production visual effects pipelines further down the line.
Mo-Sys camera tracking is designed to interface directly with the major virtual set and broadcast graphics platforms, including Vizrt, Brainstorm, Orad, and Ross, as well as dedicated hardware integrations such as the StarTracker Grass Valley collaboration. This means a broadcaster's existing broadcast graphics pipeline can plug straight into Mo-Sys tracking data without needing to rebuild their workflow around a new system.
Virtual production camera tracking for an LED wall needs to account for two things at once: where the camera is in physical space, and how that should shift the perspective of the digital environment shown on the panels. Mo-Sys StarTracker acts as a tracking system for LED wall setups by feeding real-time position and lens data into the render engine, so the parallax on screen updates correctly as the camera moves. This is core to LED wall virtual production and in-camera visual effects, where the wall itself is the final background captured live.
Unreal Engine camera tracking setup with Mo-Sys starts with a StarTracker unit mounted on the camera, which streams live position, rotation, and lens data directly into Unreal Engine over Mo-Sys LiveLink. From there, VP Pro handles the Unreal Engine camera tracking integration itself, including calibration tools, lens distortion correction, and compositing, so the virtual camera inside Unreal always matches the real one on set without manual keyframing.
Yes, low latency camera tracking is central to how Mo-Sys systems are built. StarTracker processes all tracking data on-board the unit itself rather than routing it through a separate PC, which keeps delay to a minimum. This real-time camera tracking is what allows virtual graphics, LED environments, and broadcast elements to move convincingly with the camera live on air, rather than needing correction after the fact.
Absolute camera tracking means the system always knows the camera's exact position within the studio, rather than estimating it relative to the last known point. StarTracker is the world's best-selling absolute tracking solution, using inside-out marker-based tracking so it never drifts and doesn't need constant re-homing. This is a deliberate alternative to markerless camera tracking or SLAM-based systems, which can accumulate drift over time and often require ongoing recalibration, particularly in busy studio environments.
AR graphics means overlaying digital elements, such as data visualisations, virtual sets, or branded graphics, onto a live camera feed so they appear to exist in the real space being filmed. This only works if the underlying camera tracking is accurate, since any drift between the real and virtual camera immediately breaks the illusion. Mo-Sys camera tracking, including the compact e-Sensor tracking head, is designed specifically to support augmented reality graphics for broadcast, giving productions the precision needed for close-up AR elements like sports analysis tables.
Camera tracking is the process of capturing a camera's exact position, rotation, and lens data in real time, so that any digital graphics or environment shown on screen move exactly in step with the physical camera. Without an accurate camera tracking system, virtual production breaks down: graphics drift, backgrounds slide, and the illusion falls apart. Mo-Sys builds its entire virtual production workflow around this, supplying the tracking data that AR graphics, LED walls, and greenscreen environments all depend on.
Optical camera tracking uses a camera-mounted sensor to read visual reference points in the studio and calculate position from them, rather than relying on mechanical encoders alone. Mo-Sys pioneered marker-based tracking with StarTracker, which reads small retroreflective "stars" placed randomly around the ceiling or lighting grid. As a complete optical camera tracking system, StarTracker Max and StarTracker Mini use this approach to deliver accurate 6-axis tracking with lens zoom and focus data, without needing a large array of expensive tracking cameras.
