3DEqualizer

3DEqualizer is a professional 3D camera tracking and matchmoving application used in film, television, and advertising to recover camera motion and align computer-generated elements with live-action footage. Developed by The Pixel Farm, the software provides end-to-end tools for extracting 3D camera parameters from image sequences, generating scene geometry, and aligning CG assets with real plates.

Key capabilities include automatic and manual tracking of feature points, lens distortion estimation, and robust camera solves for single- and multi-camera setups. It supports marker-based and markerless tracking, planar tracking, stereo workflows, and object or surface tracking to maintain consistent alignment even in challenging plates.

3DEqualizer exports motion data and scene information to common production pipelines, enabling integration with major 3D and compositing packages such as Maya, Nuke, and Houdini. The product offers scripting and workflow automation to streamline repetitive tasks and refine solves with user-guided adjustments.

Used extensively in high-end VFX for shot reconstruction, matchmoving, and camera relighting, 3DEqualizer is recognized for its precision and flexibility in handling difficult plates and complex rigs.

The Pixel Farm released the software in the early 2000s and has continued to develop it with new features and improvements, maintaining its position as a standard tool in professional matchmoving workflows.
