Camera Inversion

Requires the Max or Studio license

Camera Inversion converts an animated tracked camera into inverted keyframed motion on a target object, letting the camera stay fixed while the object or point cloud carries the apparent movement.

How to use it

  1. 1 Open the Aligner panel and find Camera to Object Inversion.
  2. 2 Pick the animated camera in Camera and the object that should carry the motion, often a point cloud or reconstructed object, in Target.
  3. 3 Click Invert Motion.
  4. 4 Review the new location and rotation keyframes on the target; the camera now stays still on the first frame.
  5. 5 For object tracking, mask the object and track the masked region with Heavy Tracking first.

Technical notes

This can help object tracking style workflows where the final setup is easier if the camera is stationary.

The tool reads animated camera transforms, converts them to inverted object transforms, removes camera animation, resets the camera to the first frame, and applies linear keyframes to the target.

Docs AI Masks and Polygon Masks

The masking system helps Heavy Tracking ignore or isolate moving objects. It supports SAM2 AI mask layers, manually drawn polygon layers, keyframed polygon animation, and composed mask output.

Docs Heavy Tracking

Heavy Tracking is the primary high-quality workflow for camera reconstruction and solved lens data. Use it when the shot needs strong solve quality, a specific distortion model, calibration/STMap export, masks, undistortion, dense point clouds, or mesh generation.

Docs Floor Alignment

The Aligner panel turns arbitrary reconstruction orientation into a usable Blender scene. It can snap selected floor points to the XY plane and flip inverted tracks.
