What are the post-synthesis special effects of cartoons?

As a new industry, animation attracts more and more attention from all countries in the world, especially some developed countries, such as Japan. Animation industry has become a pillar industry to stimulate national economic growth. Compared with TV art, animation art has unique artistic charm, which fully satisfies people's visual freshness and develops people's imagination through vivid cartoon animation images and complex and changeable artistic expression techniques. As an indispensable part of the three main links in the animation production process, post-synthesis technology plays an important role in the animation production process. It is the process of synthesizing all animation files and shots into an orderly production, and it is also an important factor to determine whether an animation can attract the audience's attention and have visual appeal. This paper will focus on the meaning of post-synthesis technology, the use of lens, the design of lens picture, the processing of digital special effects, and its role in the process of animation production. In order to facilitate the discussion and simplify the language, the post-synthesis technology in this paper is temporarily called synthesis technology.

1. What is synthesis technology?

Since film and television appeared on our planet, synthesis technology has become an indispensable link in the process of animation film and television production. So what is synthesis technology?

Synthesis technology refers to the process of mixing multiple source materials into a single composite picture, which can be divided into traditional synthesis technology and digital synthesis technology. The traditional synthesis technology is mainly used in the film forming process of film and tape, as well as the film developing and printing process. Although the technology is backward, the effect is very good. In the cartoon Tom and Jerry produced by Disney Company, we can see the successful application of traditional synthesis technology, while digital synthesis technology is relative to traditional synthesis technology. It mainly uses the advanced principles and methods of computer graphics to collect a variety of source materials into a computer, and then uses the computer to mix them into a single composite image, and then outputs it to tape or magnetic tape.

For a long time, digital synthesis technology has been widely used in animation production, and its synthesis technology has reached a high level. The dazzling, incredible and realistic stunt shots in The Legend of Rainbow Cat Lan Tu can fully prove this point. With the improvement of computer processing speed and the development of computer image theory, digital synthesis technology has been widely used. Animation artists strongly feel the great convenience and diversity of means brought by digital synthesis technology in the process of using computer synthesis operation. The effect of synthetic works is more exquisite and incredible than traditional synthetic technology, which has become a great driving force to promote the development of synthetic technology.

Second, the use of synthetic technology lens.

The shooting angle of the lens can be divided into objective angle and subjective angle. Pictures taken from an objective point of view are just like the audience participating in the time process, observing people's activities and enjoying the scenery. The pictures are approachable and close to life, and are most used in TV programs. Subjective angle, because of its anthropomorphic viewpoint movement mode, is often more likely to cause the audience's sense of participation and attention, and is easy to cause strong psychological induction.

Pull the lens

1、

Characteristics of pulling lens

(1) Pull the lens to form a visual backward effect; (2) Pull the lens to make the main body change from big to small, and the surrounding environment change from small to big.

2、

The function of pulling the lens

(1) indicates the relationship between the subject and its environment; (2) The artistic effects of suspense, contrast and association can be produced through the correlation of various visual factors in vertical space and vertical orientation; (3) The internal rhythm of the racquet is tight and loose. Compared with the shot put, it can give full play to the emotional aftertaste and produce many subtle emotional colors.

(2)

Shift lens

1、

Characteristics of lens movement

(1) The action of moving the lens is not limited by the subject. (2) Moving the lens helps to show the big scene.

2、

The function of moving the lens

(1) opens up the modeling space of the picture and creates a unique artistic effect; (2) It has magnificent modeling effect when representing complex scenes with large scenes, large depths, multiple levels and multiple shadows; (3) By shifting the lens with strong subjective color, it can show a more realistic effect and sense of scene; (4) Create an immersive sense of participation and use it as a subjective lens for moving people.

(3) Follow the camera

1, characteristics of the follow-up lens

(1) The screen always follows a moving subject; (2) The position of the subject in the drawing board is relatively stable; (3) The follow-up lens is different from the push lens whose camera position moves forward, and it is also different from the forward lens whose camera position moves forward.

2. It has the function of a lens

(1) The follow-up lens can continuously and meticulously show the moving subject; It can not only highlight the subject, but also explain the relationship between the direction, speed and posture of the subject and its environment; (2) Following the camera lens, the modeling effect of unchanging moving subject and changing static background is formed, which is conducive to drawing out the environment through characters; (3) The subjective shot can be displayed by following the shot from the back of the person, because the viewpoint of the audience and the person being photographed is the same; (4) Tracking and recording people, events and scenes with cameras is of great significance in documentary programs.

(4) Shake the lens

1, characteristics of panoramic lens

(1) Translation is like turning your head and looking around or realizing the visual effect from one point to another; (2) A complete panning includes three interrelated processes: framing, panning and left picture; (3) The moving process of a shaking lens from the beginning to the left picture forces the audience to constantly adjust their visual attention.

2. The function of shaking the lens

(1) to show the space and broaden the field of vision (2) to contain more visual information through the scene; (3) Being able to introduce and explain the internal relationship between two subjects in the same scene; (4) It is convenient to display the dynamic situation, direction and trajectory of the moving subject; (5) Can shake out unexpected directions, create suspense, and form visual attention and ups and downs in a shot.

(5) Push the lens

1 and the characteristics of the push lens

(1) forms a positive visual effect; (2) having clear discipline objectives; (3) make the main body from small to large, and the surrounding environment from large to small.

2. The function of pushing the lens

(1) Highlight the main figures and key figures; (2) Highlight the details and key details; (3) To hit the nail on the head by introducing the relationship between the whole and the part, the objective environment and the main tasks; (4) It can enhance or weaken the sense of motion of moving objects; (5) It can be used to adjust the picture rhythm and produce externalized emotional power.

(6) Lift the lens

1, characteristics of lifting lens

(1) The up-and-down movement of the up-and-down lens expands and narrows the visual field of the picture; (2) The viewpoint of the lifting lens is constantly changing, forming a multi-angle and multi-directional multi-composition effect.

2. Function of lifting mirror

(1) is beneficial to represent all parts of tall objects; (2) It is beneficial to express the point-surface relationship in depth space; (3) It can be used to express the scale, momentum and atmosphere of things or scenes; (4) The content conversion scheduling of one shot can be realized; (5) can show the change of emotional state in the picture.

(7) Integrated motion lens

1, integrating the characteristics of the motion lens.

(1) synthesis produces more complex and changeable picture modeling effects; (2) The motion trajectory of each shot's comprehensive motion form is multi-directional; The result of multi-mode action fusion.

2. Integrate the function of the motion lens.

(1) is conducive to recording and representing a relatively complete plot in a scene in one shot. (2) It is beneficial to realize the flow of life to integrate the continuous dynamics of moving shots; (3) It is beneficial to form the ambiguity of ideographic direction through the diversity of picture structure; (4) In a long continuous picture, the comprehensive motion lens can be "in tune" with the change of music rhythm, forming a sense of rhythm in which the picture image and music are integrated.

(8) Empty lens

Empty lens is a special lens, which is often used to introduce environmental background, explain time and space, and express characters' feelings. In the film, it can produce artistic effects such as metaphor, seeing scenery, blending scenes, rendering artistic conception, contrasting atmosphere and arousing association.

A good cartoon is the result of the comprehensive use of various lenses. Of course, Lan Tu's Biography of the Seven Chivalrous Men and Rainbow Cat are no exception. It is precisely because of the comprehensive use of various lenses and the ingenious combination of digital special effects that this film is magnificent, shocking and eye-catching.

Thirdly, the lens synthesis technology in screen design.

The lens design of animation is ultimately based on the screen. If the screen is regarded as a picture, then the lens pictures are all designed around the screen. For the screen design of the lens, it is mainly from three directions.

1, constitute

Composition is the essence of the picture, and naturally it is also the focus of lens screen design. The composition of the opening scene of the first episode of Biography of the Seven Heroes of Lan Tu is very reasonable. In order to express the specific content and visual sense of Zhangjiajie, the objects in front of the camera and various modeling factors of photography are organically organized and published in the picture, forming a certain picture form, which left a very deep impression on the audience's psychology and made people feel that Zhangjiajie is a charming tourist attraction, a fairyland on earth, birds and flowers, and clear springs in the mountains. It can be seen that composition plays a great role in animation.

Step 2 color

The color of comics is the most abundant, because all the elements created by designers in the picture are their own colors, and colors have a basic role in people's psychology. When designers set colors according to the plot of literary stories, the contrast between cold and warm colors is the best way to render the atmosphere and contrast the environment. For example, all the backgrounds in Biography of Lan Tu, the Rainbow Cat, are realistic and rich in colors, which not only render the atmosphere, but also set off the environment. In addition, the effect of the characters in the film is uniform in color and full of oriental visual tone, which has also become an important factor for the success of the film.

To sum up, color plays an important role in emotional expression, style tone and atmosphere rendering of cartoons.

3. Light and shadow

Light and shadow play an extremely important role in film photography, and can not be underestimated in cartoon pictures. The use of light and shadow in cartoons is also very particular. In the design, the designer should assume some light sources, and when these light sources with different angles point at objects, they will produce different effects. For example, The Rainbow Cat, the special effect setting of the characters in The Legend of Lan Tu, is a good proof of the great role of light and shadow in animation.

Lens design is not only a means to tell a story, but also a reflection of film style. Screen design and lens design interact with each other. As a lens screen design, it is naturally an organic combination of lens and picture.

Fourthly, digital special effects in synthesis technology.

Truth is the basic principle of artistic creation. It is not equal to life itself in real life, nor to scientific truth. Animation makes people give full play to their imagination. Good animation is a work of art that makes people linger, but no one wants to see those mediocre people. Digital special effects make this more exciting. As one of the means of animation creation, the creation of digital special effects also follows the basic law of artistic creation-authenticity. In the specific operation, I think we should pay attention to the following two points:

1, humanistic scenery, vivid acousto-optic color

Human scenery and acousto-optic color are the most important elements of audio-visual language and the main components of picture information. The principle of digital special effects processing these audio-visual elements is to restore their overall relationship. Whether it is virtual generation or composite keying, it is necessary to combine the environment and lighting conditions of the scene, unify the tone and color, and restore the texture in order to achieve a realistic effect. If this is not done well, the audience will realize what are the results of digital special effects, thus creating a sense of alienation.

2. The viewpoint, movement and trajectory of the lens are reasonable.

The viewpoint of the lens is the viewpoint of the audience, and its reasonable position should still follow the principle of true feeling. Its rationality lies in expanding people's visual habits to a certain extent, such as high-altitude remote sensing lens, which can let the audience feel the feeling of overlooking the earth and illuminating all beings. The movement of the lens also has its own rules. The traditional camera action is very strict and mature, which can't be broken in digital special effects. If the camera moves at will, the form will be divorced from the content.

1、

Digital special effects is a groundbreaking axe.

The traditional view is that digital special effects are to repair some unsatisfactory shots taken in the early stage and generate some interesting pictures. In order to pursue the fashion means of digital special effects, some creators fill some special effects shots in the picture, which formalizes the special effects and breaks away from the overall style and structure of the film. Digital special effects have become a means of expression, which has changed the way of making traditional animation. Digital special effect is a form of animation production and an indispensable content in the process of animation production. We can imagine the development of animation without digital special effects.

To sum up, synthesis technology is not only a tool for post-processing materials, but also an important link that runs through every process of comic production, and even a factor that planners and screenwriters can't forget. Synthesis technology is not to do some functional work such as generating virtual characters, but to create a reality, a reality that does not exist but is very real.

Cartoons, like movies, are also a kind of performance art. The creators tell touching stories through audio-visual language, express the feelings of characters and infect the audience. With the development of computer, synthesis technology will be presented in front of people with a brand-new look, establishing a brand-new animation language style and style, and providing unlimited imagination space for creators.

Is this it?
