3DEqualizer is the industry leading tracking solution. Artists from the world’s foremost VFX houses rely on 3DE to deliver consistent and measured results on major projects. This software is much deeper than a ‘One button solution’ and offers the level of control which highend visual effects demands.

Framestore used it on Gravity, Weta Digital used it exclusively for tracking The Hobbit in stereo, it has been used on Prometheus, Man Of Steel, The Wolverine, Iron Man 3 and The Hunger Games. It is the 'go to' tracker for high-end complex camera work. It is 3DEqualizer from Science.D.Visions.

3DEqualizer by Science-D-Vision is at the forefront of 3d tracking. It is designed to merge live action footage with digital effects, an essential element of the art of post production and movie making. It is used by most if not all of the major studios around the globe and has been used on all of films biggest blockbusters. Many of those companies rely on 3DEqualizer since its very first version which has been introduced 20 years ago – some of them exclusively!

TIPS: SOME BASIC KNOWLEDGE OF PHOTOGRAPHY IS REQUIRED!!!

Study Your Footage

Before setting your tracking points, you should play back the footage many times so you can get a feel of what's going to happen and the motion of the footage. You also need to look for features that are relatively consistent throughout the entire footage. The things you want to avoid when tracking are heavily shadowed areas or brightly lit areas and in places where the lighting changes on it. This can make it very difficult for the application to figure out what area actually needs to be tracked.

Evaluate the Footage

Some typical questions asked during the evaluation of a shot could include:

What does the camera seem to be doing? Is it moving, and if so, how? Is it locked off or panning? How fast is it moving?

What is visible in the shot? Are there tracking markers? Is anything blocking the markers?

What format is the plate? Was it shot on film? DV? HD? Is there excessive compression, grain, or noise on the images?

What needs to be placed in the shot? How accurate does it have to be?

Who will be using the matchmove, and how will they be using it?

The following are typical data a matchmover might include:

Camera information Such as focal length, aperture, and film type.

Set measurements Including camera height, focus distance, and measurements of various items in the shot.

Survey data This is very detailed measuring of the set, usually done by a professional surveyor.

Set Fitting

Matchmovers must not only uncover all the facts about the camera, but they must also reconstruct the spatial layout of the environment on the live-action plate.

How much of the environment does the matchmover need to reproduce? That depends on what is being placed into the footage. If it is simply a character walking by, the animators and TDs might only need a simple ground plane. Other scenes might need rough geometry in order to cast 3D shadows. In some cases, such as digital set extensions, the matchmove might require an extremely accurate camera, detailed geometry, and spot-on positioning. Before beginning a matchmove, it is important to find out what type of 3D object is going into the scene and exactly where it will be placed.

3D environments might come from a variety of sources. Oftentimes, matchmovers create the rough geometry themselves or are provided a set to "fit" into the plate. And in some situations, the matchmover may provide a rough set from which a more detailed set is later constructed by a modeler. Many times, matchmovers use 3D markers they've calculated during the matchmove to provide information about the spatial relationships of the scene. But regardless of where the information comes from, it is often the matchmover's responsibility to establish the environment and set up the scene so that other artists further down the production pipeline don't need to worry about it.
