Der Motion-Control-Pass ist mein wiederholbarer Take. Ich programmiere die Bewegung einmal, dann kann ich dutzende identische Passes aufnehmen – mit verschiedenen Elementen, Beleuchtungen oder Geschwindigkeiten.
A single recording pass with motion control – the identically repeatable take for VFX compositing. Multiple passes with identical movement enable complex visual effects.
What is a Motion Control Pass?
A Motion Control Pass is a single recording execution with a motion control system. Because camera movement can be repeated exactly, multiple passes with identical movement enable complex VFX composites – different elements are recorded separately and combined later.

From the crafts
Perspectives
Director
Mit mehreren MoCo-Passes kann ich Bilder komponieren, die in einer Aufnahme unmöglich wären. Derselbe Schauspieler dreimal im Bild, perfekte Miniatur-Integration – das Compositing wird nahtlos.
Producer
MoCo-Passes brauchen Zeit und präzise Planung. Jeder zusätzliche Pass kostet Drehzeit, aber ermöglicht Effekte, die anders viel teurer oder unmöglich wären.
