Choose Settings

First pick your solver mode with the Normal | Tripod switch, then choose your settings

normal settings (left) and tripod settings (right)

Normal | Tripod - normal solves shots with camera travel (parallax), tripod solves pan/tilt shots
Slow - slower but more reliable solve (CPU) - also solves k2 distortion (normal only)
Zoom - solve for varying focal length (for zooming shots)
Alpha - use alphas of the image sequence (for masking)
Roto - automatically roto foreground actor and generate alphas
Distort - account for lens distortion (undistorts the sequence in normal mode)
Densify - generate a dense point cloud of the scene (normal only)
Features - target number of features to extract per image
Extra - exposes advanced parameters for camera/tripod solving

Advanced Settings

These are the advanced parameters for standard tracking

Max Resolution: Maximum image resolution to use internally
Focal Estimate: Give the solver a focal length estimate (35mm equivalent)
Include k2: Include radial k2 intrinsic in distortion model
Max Matches: Maximum number of matches per image pair
Match Confidence: Threshold for RANSAC
Max Match Trials: Maximum number of RANSAC trials during matching
Overlap: How many neighbouring frames each frame is matched against
Min Tracks Per View: Minimum number of tracks needed for an image to be included
Min Views Per Track: Minimum number of images needed for a track to be included
Positioning Threshold: Error threshold for accepting a camera pose in solve
Bundle Adjustment Threshold: Threshold to reject outliers in solve
Triangulation Min Matches: Minimum number of matches/correspondences to triangulate a point
Reset To Defaults: Resets all advanced parameters to recommended default values

These are the advanced parameters for tripod tracking

Iterations: Solver iterations - higher means a tighter solve but slower
Zoom Smoothness: Smoothness of the solved zoom curve (only shown when Zoom is on)
Debug Video: Saves a debug.mp4 tracking overlay into the image folder
Res Scale: Tracking resolution scale (0 = automatic, recommended)
Grid Step: Feature grid spacing in pixels (0 = automatic)
LK Levels: Optical-flow pyramid levels (0 = automatic)
Reset To Defaults: Resets all advanced parameters to recommended default values
