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.

Workflow steps

  1. Prepare footage in the Select Footage or Batch panel.
  2. Choose a simple preset or custom Heavy mode.
  3. Enable zoom or rotated footage settings only when the shot needs them.
  4. Enable masks when moving objects should be ignored or isolated.
  5. Enable undistortion and dense output when the shot needs dense reconstruction.
  6. Run Autotrack Heavy and monitor progress.

Important details

Heavy Tracking uses COLMAP, a CUDA-oriented GLOMAP build, and OpenMVS-related reconstruction tools. It handles feature extraction, matching, mapping, camera reconstruction, optional undistortion, dense point clouds, and mesh generation.

Presets cover fast, balanced, heavy, and extreme style use cases. Custom mode exposes deeper reconstruction settings for difficult footage.

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.

Dense Point Clouds

Dense Point Cloud generation creates a high-detail colorized representation of the tracked scene from Heavy Tracking results. It is useful when sparse points are not enough to understand the environment.

Mesh Generation

Mesh Generation creates a reconstructed mesh from dense point cloud data. It is intended for reference geometry, proxy surfaces, and VFX layout rather than replacing final modeling in every shot.
