Set Surveys liefern die Daten für nahtlose VFX-Integration. Genaue Vermessung meiner Set-Positionen und Kamerahöhen ermöglicht perfektes Matching zwischen praktischen Aufnahmen und digitalen Erweiterungen.
The process of measuring, photographing, and documenting a filming location to capture precise spatial data for VFX work – includes LIDAR scanning, photogrammetry, HDR imagery, and physical measurements that enable accurate digital recreation of real-world environments in post-production.
What is a Set Survey?
A Set Survey is the process of precisely documenting a shooting location for VFX purposes. Spatial data, lighting information, and visual references are captured, enabling accurate digital reconstruction of the location in post-production.

Today
Set surveys are indispensable for modern VFX work. The combination of LIDAR, photogrammetry, and HDR capture provides VFX artists with precise data for seamless integration of digital elements. With the increasing complexity of visual effects, the quality of survey data is becoming ever more crucial for convincing results.
From the crafts
Perspectives
Director
Set Surveys sind die Grundlage für überzeugende VFX. Die erfassten Daten erlauben uns, digitale Elemente einzufügen, die wie Teil der echten Location aussehen – entscheidend für die Glaubwürdigkeit.
Producer
Set Surveys erfordern spezielle Equipment-Kosten und Zeit. Die Investition spart jedoch deutlich mehr Geld in der Post, da VFX-Artists mit präzisen Referenzdaten arbeiten können.
