Matchmove (match-moving & rotomation services)

Matchmove Service

Matchmove or Match moving is a technique involving visual effects that allows the insertion of computer graphics into the live-action footage. It makes sure that the position, orientation, scaling, and motion objects are all properly aligned and correct in the shot.

What is matchmove and how it is done?

Match moving is basically a method of extracting information of a camera motion from a moving picture. Match moving is sometimes also referred to as motion tracking or camera solving. In generic it is related to rotoscoping and photogrammetry.

Do not confuse match moving with motion capture, which is used to record moving objects especially human actors. For match moving, a special type of camera and seniors are required along with a controlled environment. Match moving is a typical type of motion control photography that makes use of mechanical hardware to make all the identical cameras more altogether. It is typically a software-based technology that is applied after normal footage is recorded with an ordinary camera in uncontrolled environments.

It has the capability to track the movement of the camera through the shot. This is done to reproduce a 3D animation program through virtual camera moves. When the new animated elements are brought back to the live-action shot, they appear to be perfectly matching and appear seamless.

As the process of match moving is completely software bases so it is more likely to be affordable because the cost of computer power is somewhat declined. Match moving is now established as a visual effect toll which is widely used in a television broadcast to provide yellow virtual downline effects in American football.

Where is matchmove or match moving used?

Match move was basically designed to match computer-generated images and graphics into the real scenes. This technique is more likable in the film industry. Due to the evolution of technologies, there has been tremendous development in VFX especially when we see film industries. There has been enormous change in the film industry due to the advent of various new technologies. G3D Studio provides various VFX services including match move to its worldwide clients.

In the film industry, the creation of special visual effects has permitted a high level of movie production. Match moving plays a major role in making images appear real by combining CGI and elements of real scenes.

A scene that is well created with the help of match moving can never ever be noticed by the viewer. At G3D Studio we make sure that the viewer does not get any idea about the real scene, we never let our clients visualize and know what have we done as we do it so perfectly.

There are two main categories of match moving, which are 2D match moving and 3D match moving.

1. Two-dimensional match moving:

It helps to tract features in only two-dimensional space. It does not track camera movement or distortions. This type of match moving is applicable when you need to replace the element in any image or do stabilization or another kind of effects. These types of match moving are perfect for creating realistic effects of our desire based on the footage without any major changes made in-camera perspective.

2. Three-dimensional (3D) match moving:

This tool is essential when you want to extract any 3D data from 2D footage. A 3D match-moving artist is capable of creating a virtual camera by animating effective objects with tracking information. This category of match moving has gained a significant technological edge in recent years. It has become quite a popular tool when required on the set of film making. These are also referred to as real-time match moving.

There are two main methods we adopt to accomplish match moving, which is as follows:

1. Automatic: In this method, using a computer algorithm, the features of the shot can be tracked, which results in creating points much faster than any human can create. It then calculates the solution for your tracked movement points. That is why termed automatic.

2. Interactive: This type of tracking is done when the match move artist tracks certain features through a scene by himself or herself.

At G3D Studio we make use of both the techniques to achieve the professional level of motion tracking technique.
