Camera Solve
Was ist Camera Solve?
A camera solve figures out exactly where, how fast, and in which direction the camera moved during filming, so that digital elements can be added to the footage in a way that perfectly matches the original camera's motion.

Im Vergleich
A camera solve reconstructs the movement of the camera itself by analysing the footage it captured. Motion capture records the movement of performers or objects within a scene, usually via physical markers or sensors. Both produce movement data used in visual effects and animation, but they operate on different subjects: camera solve tracks the observer; motion capture tracks the observed.
Stellen Sie es sich vor wie…
A camera solve is like a detective reconstructing a car's exact route from the security camera footage it appeared in: by watching which buildings pass at which speed and angle, the detective can map out exactly where the car was, how fast it was going, and which turns it made, even without a GPS record.
Profi-Tipp
Improve your camera solves by placing high-contrast tracking markers ( simple black-and-white dots on foam core boards ) throughout the set before filming. These give the solve software reliable, evenly distributed tracking points and significantly reduce solve errors, especially in low-texture environments.
Arten und Varianten
- A 2D camera solve (or 2D stabilisation/tracking) tracks planar motion ( position and rotation in the flat image plane ) without reconstructing full 3D space.
- A 3D camera solve fully reconstructs the camera's position and orientation in three-dimensional space, producing a point cloud of the scene and a moving virtual camera.
- Object tracking is a related process in which an individual object within the scene is tracked rather than the camera itself, allowing digital elements to be attached to or replaced on moving objects.
- Neural solve tools use machine learning to estimate depth and camera motion from footage that may lack the feature richness required by traditional point-tracking approaches.

- Camera solves are fundamental to virtually all visual effects work where digital elements must be integrated into live-action footage.
- They are used to replace location backgrounds with digital environments, to add creatures, vehicles, or props that were not present on set, and to remove unwanted elements such as safety wires or crew equipment.
- In virtual production, camera solve data enables real-time rendering of LED wall content that matches the physical camera's perspective.
- In AI workflows, solve data is used to guide the placement and animation of AI-generated assets within existing footage.
