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.

Workflow steps

  1. Select a footage sequence.
  2. Add a SAM2 layer for AI object segmentation or a Polygon layer for manual masking.
  3. Confirm the mask and let MotionMaster 3D generate the layer output.
  4. Combine enabled layers into the composed mask folder.
  5. Enable Use Mask in Heavy Tracking and choose whether to track black or white regions.

Important details

SAM2 masks are useful for cars, people, actors, and other foreground objects. Polygon masks are useful for simple shapes, corrections, or deterministic manual control.

The composed mask folder connects into the Heavy Tracking mask path so the solve can ignore moving elements or focus on a selected object region.

Heavy Tracking

Heavy Tracking is the primary high-quality workflow for more reliable camera reconstruction. It is the right starting point when the shot needs strong solve quality, dense point clouds, mesh generation, masks, undistortion, or advanced settings.

Camera Inversion

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.

Batch Processing

Batch Processing lets MotionMaster 3D run repeated tracking and reconstruction operations across multiple sequences. It is designed for larger jobs where several shots need the same kind of processing.
