The matrix-special effects

In the process of film production, we often encounter some scenes and scenes that are difficult, costly or dangerous to shoot in our lives. Because the conventional shooting technology is difficult to complete, it must be done by special effects.

In addition to quick shooting, slow shooting, reverse shooting, stop shooting and re-shooting (multiple exposures), the early film stunts all adopted some conventional trick photography techniques.

Nowadays, with the development of digital technology, the production of film special effects has made a great leap. The formation of electronic images, the development of digital technology and computer graphics have laid the foundation for digital stunts, which are a method of using computers to process digitized audio and video signals to achieve special visual and auditory effects.

Digital special effects are usually called special effects, which refer to some special visual or auditory effects obtained by unconventional shooting in film and television works, such as optical special effects, blue screen photography, infrared photography, model photography and various photography in traditional crafts.

Visual aspect

The graphics and image processing functions that computers can perform can be summarized as follows:

1 Image restoration: change the color, saturation and brightness of the original image; Delete unwanted content from the shadow.

2. Making special shapes of animal images that have disappeared or do not exist in nature,

Special environmental atmosphere such as explosion, tornado and volcano.

Scene synthesis combines actors with the above-mentioned special environment and special modeling, real scenes and computer graphics and images. This synthesis can reach dozens of layers, and it can create a very amazing composition.

5. The trajectories of animated characters and scenes, as well as various light effects and camera movements can be varied, and the tasks made by the above technologies and the movements contained in the scenes need to use animation calculation methods.

6 character replacement replaces the original character in the image with another character.

7. Virtual environment: Virtual reality technology is adopted, that is, a virtual environment is generated by a computer, and a virtual scene supporting natural direct interaction with the environment is provided by various sensing devices.

In a word, these special functions of computer graphics and images, together with real scenes and traditional photography, can create any picture that an artist can imagine.

Auditory aspect

The category of special effects includes not only images, but also sounds. Computer audio editing equipment is also a very good equipment to imitate sound. For example, she can input a kind of footsteps into the computer, and then she can change the sound characteristics of footsteps so that it seems to record any kind of footsteps. Or become other completely different sounds.

Computer stunts are more professional, and this task is mostly undertaken by large digital technology production companies. Learn martial arts well and go there to apply for a job. Besides making movies and TV, you can also make advertisements, web pages, games and MTV, which is a lot of fun.
