From the crafts

Perspectives

Cinematographer

Mo-Sys hat die Virtual Production erst möglich gemacht. Ihr StarTracker verfolgt meine Kamera im LED-Volume – das Hintergrundbild passt sich in Echtzeit meiner Perspektive an. Magie.

Director

Mit Mo-Sys-Tracking sehe ich in-camera finale Bilder. Das LED-Volume reagiert auf die Kamera – ich kann die Szene gestalten, als wäre der virtuelle Hintergrund real.

Producer

Mo-Sys ist der Industriestandard für Virtual Production Tracking. Die Investition in ihre Systeme ermöglicht uns, auf Location zu verzichten und in kontrollierten Environments zu drehen.
