Gutes Matchmoving beginnt am Set. Tracking-Marker, Lens-Daten und Survey-Informationen erleichtern die Arbeit in der Post enorm.
The VFX process of analyzing and recreating the camera movement from live-action footage in 3D software – enabling CG elements to be inserted into shots with correct perspective, position, and motion so they appear locked to the real-world environment.
What is Matchmove?
Matchmove (also Camera Tracking or 3D Tracking) is the VFX process of analyzing and reconstructing camera movement from live-action footage in 3D. This allows for the seamless integration of CG elements into shot material.

Today
Matchmove is a fundamental VFX technique – without precise tracking, there are no convincing CG integrations. Modern software and ML-based tools simplify the process, but the fundamentals remain: good feature detection, correct lens data, and careful quality control. On-set preparation with markers and survey remains essential for complex shots.
From the crafts
Perspectives
Director
Matchmove ist die Grundlage für jeden VFX-Shot mit CG. Wenn das Tracking stimmt, integrieren sich digitale Elemente nahtlos in die Aufnahme.
Producer
Matchmove ist eine frühe Pipeline-Phase. Probleme hier verzögern alles Nachfolgende. Investment in gute Tracking-Daten am Set zahlt sich aus.
