About Flaxtrax – Automated Camera Tracking
FlaxTrax is an automated tracking and solving add‑on for Blender that removes the manual steps of motion tracking. One click adds trackers, adjusts settings, processes footage, resolves the solve, cleans bad tracks, applies filters, and works toward a target solve error. The add‑on detects focal length, retains sufficient trackers across frames, and matches the tracked footage length to the original. Users set pattern and search sizes, and a masking feature excludes moving objects like people or vehicles. It supports vertical footage, advanced motions, image sequences and video files (added in version 1.7.0). The tool resides in Blender’s motion track side panel and typically completes calculations within twenty‑five minutes. A demo video illustrates its workflow.
