AutoTrack earns its place in the blender_extensions library by pairing automated substep tracking with a dual-pass solver that usually reaches 1px or lower accuracy, plus practical extras like annotation masks, sensor presets and a dedicated tripod solving mode.
AutoTrack is a Blender add-on for automatic 3D tracking and solving, built to handle 2D feature tracking and camera solving inside the Movie Clip Editor. It uses smart logic to track markers forwards and backwards, analyzes track density at the substep level, and runs a dual-pass solver to find the best reconstruction error.
The add-on breaks long clips into substeps for tracking stability and applies a filtering algorithm that works at the substep level to prevent bald spots and maintain marker density. Its dual-pass solver runs an initial solve, automatically cleans up bad tracks, then performs a final high-precision solve that usually reaches 1px or lower accuracy. Annotation Masks let you draw zones with the Grease Pencil or Annotation tool to exclude markers or restrict tracking to a region, while sensor presets cover Full Frame, Crop Sensor, MFT and smartphones.
Additional modes include a dedicated Tripod Mode for tripod and nodal pans, solve refining for focal length and radial distortion, custom lens data entry in the Solver tab, and a Surface Generator that turns the point cloud into projected surfaces with adjustable resolution and radius.
AutoTrack is best for vFX artists tracking footage and solving camera motion inside Blender's Movie Clip Editor.
AutoTrack is completely free to download and use.
AutoTrack lists compatibility with Blender 4.2 LTS and newer, so it runs on 4.2 and later releases. It works inside the Movie Clip Editor, where you load footage and open the AutoTrack tab from the Sidebar with the N key. The extension requires no special permissions to install. If you are on an older Blender build, you would need to update to at least the 4.2 LTS release before the add-on will load and function as described here.
AutoTrack runs from the Movie Clip Editor. Open the editor, load your footage, then press N to open the Sidebar and click the AutoTrack tab. Adjust settings such as Focal Length and click Start Tracking, and the add-on handles tracking, filtering and solving while giving status updates. Once the tracking and solving finish, you can tweak the Surface Generator directly in the panel, and you can still adjust the focal length later using the Quick Resolve option.
AutoTrack 4.2.0 is described as an Ecosystem and Compatibility update. It removed the internal Check For Updates button to conform more closely with the official Blender Extensions platform terms of service. It also removed the View Console while running toggle from the Miscellaneous panel, which eliminated a Windows-specific background call and improved compatibility for macOS and Linux users. This version targets Blender 4.2 LTS and newer and is the release currently listed on the developer's page.
AutoTrack is listed as free in this catalog and is distributed under the GNU General Public License v3.0 or later. The developer also mentions accepting donations to support continued development of the add-on. For current licensing terms and any distribution details, check the developer's page. Because it is released under the GPL, you can use it under the terms that license provides, and the extension notes that it requires no special permissions to run.
AutoTrack requires no special permissions, according to its extension listing. It installs like other Blender extensions, either by dragging and dropping the add-on into Blender or by downloading and installing it from disk. It targets Blender 4.2 LTS and newer and ships as a compact download. No additional dependencies or elevated access are noted for it to run inside the Movie Clip Editor, where all of its tracking and solving tools live.
