Evolution process of film and television special effects

Evolution process of film and television special effects

MAYA software can be used for film and television special effects. It entered the market in 1998. It is a cross-platform software and can be used on any operating system. The following is the evolution process of film and television special effects that I have compiled. I hope you like it!

First, early film special effects

1895, the first special effect in film history appeared in The Execution of Queen Mary. The beheading scene of the heroine in the play was completed in an "alternative shooting way". When a shot is being filmed, he stops the camera, tells the actors to go away, puts on props, and then turns on the camera to connect the films before and after the stop, which has caused the special effect of being beheaded. This technology is not strange now, but it was whimsical at that time.

Second, CG special effects (computer synthesis)

Star Wars (1977) is a miracle in film history. Because of the need of difficult lenses such as space warfare, the cinema uses a motion control camera system called Dykstraflex, which allows the camera to repeat the same motion trajectory accurately and synthesize the lens conveniently. The detonation of the spacecraft is also a problem, because the model is too small, and the direct explosion comes too fast, so it is difficult to record the whole process on film, so the pyrotechnics try to deal with it one by one and then synthesize it later.

Third, modern film special effects.

Most of the special effects of modern movies are made by blue screen keying technology, and its highly developed digital technology makes those characters and scenes that once existed only in people's imagination truly appear in front of the camera, making people experience unprecedented audio-visual shock, which is also the greatest charm of modern movies! That "magician" who makes time and space stagger and the scene change is it! "Keying", that is, channel extraction, is to superimpose the content taken in the studio with the content taken on location through channel extraction to create a more exciting picture effect. In application, blue screen technology is the most important means to extract channels. After shooting people or other foreground content, it uses the difference of chromaticity to remove the monochrome background.

Expansion: film and television special effects processing technology

1, traditional special effects technology

Traditional special effects technology appeared very early, the simplest of which is makeup, which is also the most effective; There is also a scene, which can realize the setting of a specific scene; Fireworks special effects, in early film works, fireworks special effects can often play a very good role; Early movies, this is also a common special effect means in the early days.

2. CG special effects technology

CG special effects are the so-called computer special effects, which are mainly determined by two aspects: first, the traditional special effects technology can no longer meet the needs of film performance, while the audience's requirements for film and television works are getting higher and higher, requiring more novel and powerful special effects technology; Second, with the continuous development of computer technology, electronic technology and multimedia technology, various technical requirements can meet the new means of special effects production. Now, we can classify special effects according to their functions:

First, three-digit special effects technology.

Three-dimensional special effects technology is indispensable in many movies, and it should be used to contrast the roles and set the scenes. Therefore, it can be said that the three-digit special effects technology is the most difficult and difficult to solve in computer special effects technology. The general process of 3D technology is: modeling-determining materials and lighting-image binding-animation and final rendering. At present, the software of 3D special effects technology mainly includes MAYA software, realflow software and c4d software.

Second, digital landscape painting technology and conceptual design technology.

Many buildings and backgrounds in film and television works simply do not exist in life. At this time, film and television designers need to combine their own imagination to design digital landscapes and concepts, presenting huge fleets, continuous mountains and magnificent palaces to the audience. In this process, the most important thing is conceptual design. Today, with unprecedented economic development and splendid culture, people's imagination is endless, and they are also very critical of film and television works, so the quality of conceptual design works greatly affects the popularity of film and television works.

Third, synthetic special effects technology.

China people are no strangers to synthetic special effects technology. In many martial arts works, the flying heroes we see are all realized by synthetic special effects technology. Generally speaking, the technology of synthesizing special effects is realized in this way. Actor's actions (fighting, jumping, etc.) ) shooting from the sky. Actors need to use wire ropes to shoot on a blue screen or a green screen. Finally, the blue screen and wire rope are removed by computer software technology, and then the necessary sky scene is synthesized, which brings the effect of air fighting to the audience and gives people a sense of reality.

To sum up, in today's unprecedented development of film and television industry, computer software technology, microelectronics technology and multimedia technology will inevitably continue to develop, and film and television production is inseparable from special effects processing. Although there is a certain gap between China and developed countries in the production and processing technology of special effects, it can basically meet the needs of the audience. In the future, the processing technology of film and television special effects will also develop in the direction of humanization and intelligence, and the concept of special effects will be integrated into film and television works.
