What is 3D Equalizer 4?




3D Equalizer 4 is a software that allows you to track the movement and position of a camera in a video sequence, and reconstruct the 3D geometry and motion of the scene. This enables you to insert computer-generated objects or effects into the footage, creating realistic and seamless composites. For example, you can add explosions, creatures, buildings, or landscapes to a live action shot, or remove unwanted elements from it.


3D Equalizer 4 is not just a simple point tracker. It is a sophisticated tool that can handle complex shots with varying camera parameters, lens distortion, zooming, motion blur, rolling shutter, occlusion, and more. It also offers a high level of customization and control over the tracking process, allowing you to fine-tune the results and optimize the quality. Moreover, it supports Python scripting, which lets you automate tasks, create custom tools, or integrate with other software.


Features and benefits of 3D Equalizer 4




Here are some of the main features and benefits of using 3D Equalizer 4 for your visual effects projects:


Camera tracking and 3D reconstruction




One of the core features of 3D Equalizer 4 is its ability to track the camera movement and position in a video sequence, using either manual or automatic point tracking methods. You can create multiple point groups to track different regions or layers of the scene, and assign different weights or constraints to them. You can also use survey data or reference frames to improve the accuracy of the tracking.


Another feature of 3D Equalizer 4 is its ability to reconstruct the 3D geometry and motion of the scene from the tracked points. You can create various types of primitives, such as planes, spheres, cylinders, or cubes, or import your own models from other software. You can also use line-up controls to align the models with the footage, or use scripts to transform them into poses. You can then export the camera data and the models to other software for compositing or rendering.


Lens distortion and focal length estimation




Lens distortion is a common issue that affects the quality of the tracking and compositing. It refers to the deformation or curvature of the image caused by the optical properties of the lens. If not corrected properly, it can result in misalignment or mismatch between the live action footage and the digital elements.


3D Equalizer 4 has a powerful feature that can estimate and correct lens distortion automatically or manually. It can use a grid or a checkerboard pattern to measure the distortion, or use the tracked points to calculate it. You can also adjust the distortion parameters manually, such as the radial, tangential, or anamorphic coefficients. You can then apply the distortion correction to the footage, or export it as a STMap or a Nuke script.


Focal length is another important parameter that affects the tracking and compositing. It refers to the distance between the lens and the image sensor, and determines how much of the scene is captured and how it is magnified. If not estimated correctly, it can result in incorrect perspective or scale between the live action footage and the digital elements.


3D Equalizer 4 has a feature that can estimate the focal length automatically or manually. It can use the tracked points, survey data, or reference frames to calculate it. You can also adjust the focal length manually, or use a zoom curve to account for variable zooming. You can then export the focal length data to other software for compositing or rendering.


Multiple point groups and survey data




Another feature of 3D Equalizer 4 is its ability to handle multiple point groups and survey data. Point groups are collections of tracked points that belong to different regions or layers of the scene. For example, you can create point groups for the foreground, background, moving objects, or static objects. You can then assign different weights or constraints to each point group, such as fixed, free, or smooth. This allows you to control how much each point group influences the camera solution, and achieve more accurate and stable results.


Survey data are measurements or coordinates of known points in the scene, such as markers, landmarks, or GPS data. They can help improve the accuracy and reliability of the tracking and reconstruction. For example, you can use survey data to define the scale, orientation, or origin of the scene, or to calibrate the camera parameters. You can import survey data from other software, such as Maya or Houdini, or enter them manually in 3D Equalizer 4.


Python scripting and customization




One of the most powerful features of 3D Equalizer 4 is its support for Python scripting and customization. Python is a popular and versatile programming language that can be used to automate tasks, create custom tools, or integrate with other software. 3D Equalizer 4 has a built-in Python interpreter and editor that allows you to access and manipulate its data and functions. You can also use external Python modules or libraries to extend its capabilities.


Some of the things you can do with Python scripting in 3D Equalizer 4 are:


  • Create custom user interfaces or menus



  • Import or export data from other formats or software



  • Perform calculations or operations on points, models, cameras, or images



  • Create custom tracking algorithms or methods



  • Generate reports or logs



  • Debug or test your scripts



You can also use Python scripts to create custom plugins for 3D Equalizer 4, which can be loaded and executed from within the software. Plugins are useful for adding new features or functionality to 3D Equalizer 4, such as new tools, commands, widgets, or dialogs. You can also share your plugins with other users or developers.


Compatibility and integration with other software
