Cinematographer
Der Greenscreen-Monitor zeigt mir, was wir wirklich drehen. Ohne Live-Preview kann ich Framing und Lichtabstimmung nur raten – mit Preview sehe ich das Ergebnis.
Specialized monitor system that displays real-time composite of green screen footage with background elements – enables director and cinematographer to evaluate framing, lighting, and performance against the intended final image during principal photography.
What is a Green Screen Monitor?
A Green Screen Monitor is a real-time composite system that shows a live combination of the green screen footage with the planned background during shooting. This allows everyone involved an immediate preview of the final image.

Perspectives
Director
Live-Composite ist transformativ – ich sehe meine Schauspieler in der finalen Welt, kann Performance und Blocking entsprechend anpassen. Keine Vorstellungskraft mehr nötig.
Producer
On-Set Preview verhindert teure Überraschungen in der Post. Wenn am Set schon klar ist, dass etwas nicht funktioniert, sparen wir Reshoots.
