In this tutorial by Polyfjord, discover a fully automated workflow for 3D camera tracking using free and open-source tools like COLMAP, FFmpeg, and a custom script. Learn how to convert video footage into precise 3D tracks and point clouds, then import them into Blender for seamless integration.

Key Steps:

• Setup: Download and organize COLMAP, FFmpeg, and the batch reconstruction script.
• Process: Convert video footage into an image sequence, then run it through COLMAP for photogrammetry-based tracking.
• Import: Use the Photogrammetry Importer add-on in Blender to bring in the 3D camera and point cloud.
• Optimize: Create proxy files for smoother playback and refine the scene with ground planes or mesh objects.

Tips:

• Disable image stabilization in your camera for best results.
• Use the Blackmagic Camera App for full control over settings.
