Set extensions can get very complex depending on the camera movement. The camera tracker in DaVinci Resolve Studio and Fusion Studio can handle many scenarios.
It all starts with a good camera track. The Fusion camera tracker offers an advanced workflow all within one tool.
First, it identifies and tracks features across the shot. If those features are well spread across the frame, you are off to a good start. Ideally, you want to have some points in the foreground, midground, and background.
Next, you provide information about focal length and camera sensor. Don’t worry if you don’t have that information at hand. You can start with your best guess and update later if you encounter problems.
Then, the actual solving takes place. Fusion reverse calculates the 3d camera movement from the tracked features. Afterward, you can export a 3d camera object together with a point cloud. The point cloud is only needed for reference. It displays the tracked features in 3d space.
Finally, you can place 2D image planes into 3D space or even import full 3D models.
