Show Track Points Identifies detected features as 3D points with perspective hinting (3D Solved) or 2D points captured by the feature track (2D
Source).
Render Track Points Controls if the track points are rendered as part of the effect.
Note: When the effect is selected, track points are always shown, even if Render Track Points is not selected. When enabled, the points are
displayed into the image allowing them to be seen during RAM preview.
Track Point Size Changes the displayed size of the track points.
Create Camera Creates the 3D camera. A camera is automatically added when you create a text, solid, or null layer from the context menu.
Advanced controls Advanced controls for the 3D camera tracker effect:
Solve Method: Provides hints about the scene to help in solving the camera. Solve the camera by trying the following:
Auto Detect: Automatically detects the scene type.
Typical: Specifies the scene as that which are not purely rotational, or mostly flat.
Mostly Flat Scene: Specifies the scene as mostly flat, or planar.
Tripod Pan: Specifies the scene as purely rotational.
Method Used: When Solve Method is set to Auto Detect, this displays the actual solve method used.
Average Error: Displays the average distance (in pixels) between the original 2D source points and a reprojection of the 3D solved points
onto the 2D plane of the source footage. If a track/solve was perfect, this error would be 0 and there would be no visible difference if you
toggled between 2D Source and 3D Solved track points. You can use this value to tell if deleting points, changing the solve method, or
making other changes is lowering this value, and thus improving the track.
Detailed Analysis: When checked, makes the next analysis phase do extra work to find elements to track. The resulting data (stored in the
project as part of the effect) is much larger and slower with this option enabled.
Hide Warning Banner: Use when you don't want to reanalyze footage even though there is a warning banner indicating that it needs to be
reanalyzed.
Exporting 3D Camera Tracker data to 3D applications
You can export 3D Camera Tracker data to 3D applications like
Do the following:
1. Download plug-ins for exporting camera tracking data. For example, from
2. Install the plug-ins to the plug-ins folder.
3. Choose File > Export > (plug-in manufacturer]. For Cinema4D, choose Cinema 4D Exporter.
4. Name the file and click Save.
5. Open the file in the 3D application.
