Again, don’t spend too much time in this situation it is better to skip the Camera Tracker node and find another solution. Locked-off shots: If the camera does not move, there is no way to calculate which objects are closer and which are nearer. In this case, it’s better to skip the Camera Tracker node and find another solution. If everything is at the same distance from the camera, there is no way to calculate depth. You must be able to identify objects further away and objects that are nearer as the camera moves. Lack of depth: Camera tracking requires parallax in a clip in order to work. Here is a list of the types of shots to look out for, as they can be big headaches for camera tracking: Some are fixable, while for others you just have to admit defeat and figure out another solution. Certain types of clips will cause more significant problems for camera tracking than others. If you can identify potential issues before you even track or solve the shot, you can save yourself much time. Options: Used to customize the look of the onscreen overlays.Ĭlips That Don’t Work Well for Camera TrackingĮven though the Camera Tracker is somewhat automatic, it sometimes needs your help. Solve: Calculates the 3D placement of the 2D tracking points and reconstructs the camera.Įxport: Generates a Camera 3D node, a Point Cloud node, and a 3D scene in the node tree. These five tabs are:Ĭamera: Configures the basic Camera parameters. Five tabs at the top of the Inspector are roughly laid out in the order in which you’ll use them. The Camera Tracker encompasses this complete workflow within one tool. Once you complete these steps, an animated camera and point cloud are exported from the Inspector into a 3D composite. Solving, which calculates the virtual 3D scene. Tracking, which is the analysis of a scene. The Camera Tracking Workflow Camera tracking has two main phases: The point cloud can then be used as a guide when integrating other 2D or 3D elements alongside live-action features. The Camera Tracker’s purpose is to create a 3D animated camera and point cloud of the scene.Ī point cloud is a large group of points generated by the solver that roughly recreates the 3D positions of the tracked features in a scene.
