(London, UK--January 23, 2017) Mo-Sys Engineering, designer and manufacturer of innovative camera technology products for the film and broadcast industries will launch StarTracker - hands off camera tracking system for green screen production at BSC Expo 2017.

It’s the first hands off camera tracking system that works totally in the background throughout the entire sound-stage. Once set up, it will track the camera position without a need of realignment from scene to scene all day long.

After a very successful introduction of StarTracker to the broadcast industry, with clients already using it to include the BBC, SKY, FOX, ESPN and more, Mo-Sys has now made the system accessible for film and post production. To allow integration into various workflows they have added a Motionbuilder plug-in, which allows to visualise the scene by overlaying the camera image with CG elements, such as virtual set extensions or CG characters, giving a crude idea of what the scene will look like at its final stage, a valuable asset for every production that heavily relies on green-screen filming.

Star Tracker provides constant and robust camera position data for on-set-previsualisation, that in addition can be captured for the post-production workflow. The tracking system utilises an upward looking sensor attached to the main camera that points at the ceiling, as opposed to looking forward into the set. It is therefore independent of movements in the scene, occlusion of the main camera or changes in set lighting. It also allows for 360 degrees camera movements and even works in low light conditions.

The reference ‘stars’ on the studio ceiling

Retro-reflective stickers, the ‘stars’, are used as references on the ceiling. They can be easily stuck to any fixed structures such as the ceiling itself, pipes, trusses, lighting grid, and at multiple heights. The stickers allow expansion of the tracking area at little cost, and even enable one StarTracker system to work in several sound-stages.

The star-stickers are applied easily and randomly without any measuring. A one-time 30-minute procedure auto-maps their positions and references them to the real world, after which no further “star”-calibration or homing is required. StarTracker is very versatile and can be used with cameras on all kinds of support systems, such as tripod, dolly and crane. It can also be used with a handheld camera.

StarTracker enables absolute tracking anywhere in the sound-stage at the flick of a switch.

Patent pending StarTracker technology is very accurate, immune to lighting and simple to use.

Mo-Sys will also show their remote heads at BSC:
  • L40 remote head: a precise, robust and light weight 2-axis camera head for high-end digital cinematography. It’s very compact but capable to carry even heaviest camera packages. At the core of the L40 is Mo-Sys’ highly robust and precise motor drive with zero backlash, providing lag-free operation. Payload 40 kg. There is a back-pan option.
  • B20 remote head: Designed for broadcast ENG type cameras, the B20 was specially designed with virtual set applications in mind and lends itself to long-term installations in TV studios. It has the same fast response and strong gears as our other heads, yet it is lighter and more cost-efficient. The optimised gear drives make it extremely quiet, which renders it perfect for live studio environments. Payload 20 kg.
