How We Replace Subjects in Motion

CUTR delivers frame-accurate subject replacement. We preserve native optical physics, vehicular reflections, and complex volumetric lighting for elite post-production results.

VFX Grade Fidelity

Every composite is calibrated to match the original plate's lighting, camera angle, and motion vectors perfectly.

01
High-Fidelity Capture
Ingest Source Plate

Upload your reference video and target image. Our engine maps the 3D geometry, camera motion, and volumetric lighting of the original scene.
