GeoTracker is a plugin that brings 3D-object tracking to Adobe After Effects. Match-moving tasks are done with a snap with GeoTracker — what usually requires a team of motion tracking specialists can be done by a VFX artist with no tracking skills and with less time spent. Now this technology is available for users of After Effects, so they can use object tracking to reach the new level of motion graphics and design.
Intuitive model manipulation
Our pin-based approach helps you to keep your model under precise control while placing and moving it in 3D space naturally and effortlessly. All that in the standard 2D viewport without additional windows or gizmos.
Focal length estimation and tracking
Obviously, you need to know exact camera settings for precise tracking. But no worries if you don’t! We understand it happens often in post, so we added reliable focal length estimation to GeoTracker. More than that, GeoTracker can estimate focal length during tracking too, so you can track objects in footage where focal length is constantly changing (zoom lens). You can watch our Camera Basics tutorial to learn more.
Defiant of occlusions
Occlusions are among the main issues that mess up 3D tracking. GeoTracker can deal with them so well, most of the time you won’t need to even think about them. But for some very advanced cases, we added support for 2D masks, so you can exclude problematic areas from tracking manually.
Since the version 2023.1 you can also use 3D masks to mark the parts of the model that you want to exclude from tracking. Please watch our masking tutorial to learn more.
Built-in 3D models (primitives & human head)
3D object tracking requires a 3D model. GeoTracker provides you with four built-in primitives: plane — for screens, walls and any flat surfaces; sphere — for balls, heads and other spherical objects; cube — for vehicles, boxes, buildings, etc; and cylinder — for bottles, rockets, cups and so on. With v2023.1 and newer you can use a generic head to track human heads and faces. You can also export all these models as .OBJ and .FBX files.
Feels like built-in
We all know that the 3D software world is so diverse, it’s uncomfortable to even think of adopting new software. With this in mind, we strive to provide the most intuitive and native experience to our users — you won’t need to learn another interface and memorise new fantastic button names and where to find them. We’ve designed GeoTracker to look, feel and work like if it was the best built-in tool of After Effects that existed from the very beginning and still is its main selling point.
