PCamSolver earns its place for tackling shots a standard camera solve can't reconstruct, from single-plane tracks and sparse close-ups to a quick approximation of zoom or lens breathing.
PCamSolver converts limited 2D tracker motion into practical camera or object animation inside Blender. Depending on the shot, it can use one, two, three, or many clip tracks, and an optional Depth Reference object provides a spatial reference for depth-aware solving.
The add-on targets situations where a standard camera solve struggles: close-up shots with only a few reliable tracking points, camera motion that is mostly parallel to a wall or another flat surface, simple forward or backward camera movement, and shots where all available trackers lie on a single plane and reliable depth cannot be reconstructed. It also covers cases where the camera position is animated manually but the viewing direction needs to be refitted to tracked points.
Two conversion modes work from scale changes: Z-Depth turns scale changes into movement along the camera's depth axis, while Focal Length turns scale changes into focal length animation. This allows a quick approximation of zoom or lens breathing, which Blender's standard tracking tools do not handle directly. Simple object tracking for elongated shapes such as swords, rods, or pipes is supported as well.
PCamSolver is best for close-up shots with only a few reliable tracking points, camera motion parallel to a flat surface, and simple forward or backward camera movement.
PCamSolver is completely free to download and use.
PCamSolver supports Blender 4.2 LTS and newer, so any release from that version onward can run it. The add-on installs as a Blender extension, and the download is packaged as a versioned zip. If you are on an older Blender release, you would need to update first, since 4.2 LTS is listed as the minimum supported version. For current compatibility details and any newer builds, the developer's GitHub page is the place to check before adding it to a project.
PCamSolver installs like other Blender extensions. You can drag and drop the add-on directly into Blender, or download the zip and install it from disk through Blender's extensions preferences. Once enabled, it becomes available for converting 2D tracker motion into camera or object animation. The package is distributed as a versioned zip file, and the developer's GitHub page hosts the source alongside further material for setup and reference.
PCamSolver is listed as free here and is released under the GNU General Public License v3.0 or later, an open-source license. That means you can use and modify it under the terms of the GPL. For the full license text, source code, and any conditions attached to redistribution, the developer's GitHub page is the reference. Licensing terms can change over time, so it is worth confirming the current details there before relying on it in a project.
PCamSolver does not require a Depth Reference object, since it is optional. When provided, the Depth Reference object gives a spatial reference for depth-aware solving, which helps in shots where all available trackers lie on a single plane and a standard camera solve cannot reconstruct reliable depth. Depending on the shot, the add-on works from one, two, three, or many clip tracks, so it adapts to how much reliable tracking data a scene offers, with or without that extra depth cue.
