On the Application of Computer Multimedia Technology in Film and Television Post-production Abstract: In recent years, computer multimedia technology has been widely used in film and television post-production and has become a powerful tool for film and television post-production. Influenced by computer multimedia technology, the working style of film and television producers has changed greatly, and the working efficiency has improved obviously. It can be said that computer multimedia technology has brought a broader creative space to film and television production. This paper analyzes the reasons for the existence of traditional film and television post-production and expounds the role of multimedia technology in film and television post-production.
Multimedia technology, film and television post-production application
As early as the late 1980s, computer multimedia technology appeared. This technology refers to the collection, processing and storage of various multimedia information on the basis of the development of digital technology, which constitutes a logical and complete interactive technology. In the whole computer field, multimedia technology is the most popular technology.
Due to the rapid development of science and technology, a large number of electronic products have rapidly entered people's production and life, such as computer multimedia technology, digital equipment, advanced editing software, etc., which directly affects the thinking of film and television production technicians and is constantly changing the working methods of film and television producers. Influenced by computer multimedia technology, film and television producers have a broader creative space, and then create a large number of excellent film and television works for people.
In recent years, due to the rapid development of computer technology, digital technology, storage technology and communication technology. Computer multimedia technology has gradually matured. Combining with animation technology and digital framing technology, it can give full play to the imagination and creativity of technicians, not only create better film and television works, but also fundamentally change the working methods of film and television producers. Computer multimedia technology has a great influence on post-production of film and television.
1 reasons for the existence of traditional film and television post-production
In the traditional mode, the post-production of film and television works is restricted by shooting materials, scientific and technological level and other factors, and the post-production of film and television can not meet the needs for various reasons.
(1) Traditional film and television works are basically shot on tape, and some manual editing is needed after shooting, so that the works can fully express their creative intention. The strategy of manual editing is mainly linear editing, and the material is cut into continuous pictures according to the requirements of the work through electronic strategy. Generally, the combination editing method is adopted, and the corresponding editing is carried out according to the order of the works to make it a continuous picture, and then the insertion editing method is used to replace a certain content with the same length, but it is impossible to shorten, delete or lengthen a certain content unless the whole content is deleted and then recorded again. This method can't change the length of the work, so there are many inconvenient factors in the revision, and after many revisions, there will often be some attenuation, which will reduce the quality of sound and picture.
(2) In the traditional post-production, it basically depends on the personal level of the editors. However, the ability of editors to work is limited. If they rely too much on the editors, there may be unreasonable editing, incoherent shots and other reasons that lead to problems in the film.
(3) In traditional post-production, films are just clips. In the post-production work, if there are some reasons for the film, the common and most feasible strategy is to call the actors back and re-shoot the pictures with reasons, which will not only consume a lot of time, but also consume a lot of manpower and material resources.
2 The application of computer multimedia technology in post-production of film and television at this stage
2. 1 The role of computer multimedia technology in post-production of film and television
With the increasing application of digital technology in film shooting and post-production of film and television dramas, multimedia technology has well solved the defects of post-production of traditional film and television dramas. The role of multimedia technology in film and television post-production mainly includes:
2. 1. 1 The application of multimedia technology fully ensures the quality of film and television programs.
Compared with the traditional mode of production, computer multimedia technology has its powerful advantages. First, computer multimedia production technology avoids the loss in the storage process and is more conducive to ensuring the quality of signals. Secondly, computer multimedia technology has broken through the limitation of editing a single time series, and can be arranged into a variety of sequences, which is fast, simple and random. Thirdly, the digital signal has strong anti-interference ability, which makes it easier to maintain the integrity of the film during storage, copying and transmission.
2. 1.2 The application of multimedia technology has improved the production efficiency of film and television dramas.
Traditional production is linear editing, but now more flexible and effective nonlinear editing is widely used in post-production of film and television. This makes the film and television abandon the previous strategy in post-production and make it more convenient and flexible to edit and edit the film. Even if there is an error in the process of cutting and editing, it can be easily repaired. It not only saves editing time, but also improves the production efficiency in the later stage of film and television.
2. 1.3 provides more means of film and television creation and enriches the expressive force of film and television.
The traditional shooting strategy is to record and completely reproduce the shooting scene. Modern digital production technology converts all the information on the shooting scene into information streams that can be recognized by the computer and recorded in the corresponding storage devices, which makes it possible to change these information streams. We can add, delete and modify the information in the film and television works at will by using the relevant software of the computer, and enrich the expressive force of the film and television works by using the powerful function of the digital production technology of the film and television, so as to obtain an extraordinary audio-visual feast.
2. 1.4 reduces the investment in post-production equipment of color TV and ensures the quality of film and television works.
Modern digital film and television production technology adopts a more flexible and effective nonlinear editing method, which makes the post-production of many films and televisions completely completed by one computer. When editing a video with a computer, you can achieve many processing effects, such as special effects. This not only reduces the cost of post-production equipment, but also ensures the quality of film and television works.
2.2 The influence of computer multimedia technology on post-production of film and television
2.2. 1 film and television production
Due to the rapid development of science and technology, after using various advanced processing strategies, such as shading, texture matching and so on. , will get more vivid three-dimensional animation, at the same time, people's facial expressions will change a lot. Most importantly, we can use computer multimedia technology to set up various film and television scenes, and we can also create scenes or scenery that do not exist in real life with our imagination and creativity. The scene created by editing the real scene ensures the proper connection, so that the film and television works produced will be more popular.
2.2.2 Film editing and editing
On the one hand, picture editing: this work is relatively simple, the producer can change the length and position of the picture at will by dragging the mouse, and can also modify the color tone and elevation angle. Combined with image processing software and nonlinear editing software, it can achieve good results and bring certain impact to the audience's vision. On the other hand, sound editing: in sound production, nonlinear editing is basically the same as traditional production, and most of them are made separately. In the audio workstation, with the help of computer multimedia technology, you can quickly complete all kinds of routines and stunts, and at the same time apply the editing results to the final mix. Before the final mixing recording, there can still be a separate dialogue, and music creation and editing are always consistent with the picture. This is very important for sound production in the later stage of film and television.
On the application of computer multimedia technology in the post-production of film and television papers 2. The application of video image drawing technology refers to the use of computer multimedia technology to edit and process film and television works and add certain effects to realize the expressive force of scenes and pictures in film and television works. Video image rendering technology promotes the rapid development of film and television industry, because it can make post-production of film and television more rapid and efficient, save manpower and material resources for film and television production, and achieve good audio-visual effects. Therefore, video image rendering technology promotes the development of film and television works such as micro-movies and independent films, and creates good opportunities for individuals or organizations to create film and television works. Many of these film and television works have achieved certain results. For example, in spring, the rising sun sang the video of Migrant Workers, and the youth film old boys written, directed and performed by Chopsticks Brothers.
The application of dynamic image processing technology is a computer multimedia technology which has great influence on post-production of film and television. Before the application of computer multimedia technology, the role of film and television post-production was very limited, and even the effect of enhancing expressiveness could not be added. Despite the lack of technology, a classic like A Dream of Red Mansions appeared. Due to the increasing entertainment demand of the audience, the post-production of film and television has to face new opportunities and challenges. The application of dynamic image processing technology makes it possible to add various post-effects to film and television works, such as realizing delicate light and shadow and magnificent scenes. This technology has two major influences on the post-production of film and television: first, it promotes the development of sci-fi film and television works, which is due to the characteristics of sci-fi works themselves, and it is often necessary to insert unreal scenes into the whole works; The second is to improve the quality of the whole film and television works. For example, in the sci-fi giant Inception released on 20 10, the dynamic image processing technology was adopted, which won the recognition and love of the audience.
Application of 3D imaging technology In recent years, as the key content of computer technology development in film and television post-production, the application of 3D imaging technology has brought rich and delicate audio-visual feelings and experiences to the audience. This technology not only makes it possible to reflect the pictures and scenes in the film and television works in an all-round way, but also can display the characters, scenes and specific pictures in the film and television works from multiple angles and directions, supplemented by three-dimensional technology, which greatly improves the audience's experience. In addition, the application of three-dimensional imaging technology not only makes the creation of film and television works that were difficult to achieve in the past faster, but also promotes the emergence of many unimaginable program forms. The most famous is the virtual idol that originated in Japan. Through the use of 3D imaging technology, virtual idols move from 2D display to 3D display, which not only promotes the application of mature operating systems, but also promotes the rapid development of animation, games and other industries to a certain extent, providing a good opportunity for the vigorous development of the tertiary industry in China.
Promotion strategy in post-production of film and television
One of the main problems facing the development of computer multimedia technology in China is insufficient capital investment. For the same type of film and television works, compared with the capital investment, manpower allocation and production time of film and television works in developed countries, the film and television works created in China are far behind. These factors are also the important reasons why China's final film and television works can't achieve amazing artistic effects. Even so, some creative teams of film and television works were eventually dissolved due to lack of capital investment. It can be seen that the application of computer multimedia technology in film and television production needs a lot of funds to support and guarantee. This also requires the co-organizers to provide necessary financial support for the production and research and development of film and television works, so that the creative team can obtain financial guarantee to obtain high-quality and high-level film and television works.
Multi-channel personnel training is guaranteed by capital investment. At the same time, all departments should give certain resources support, strengthen the training and ability improvement of computer multimedia technology for talents, so as to promote the rapid development of computer multimedia technology in the production of film and television works. Talent cultivation is an important foundation for the development of computer multimedia technology. Although the level of informatization has been improving, many technical talents have poured into the film and television industry; However, there is a great shortage of high-end technical talents in this industry, which is the most common situation and challenge faced by the computer multimedia film and television industry in China. Many colleges and universities offer courses related to computer multimedia, and some social organizations also actively provide relevant training services to make profits. It is precisely because of the different learning methods that the professional level of computer personnel varies widely. At this time, it is necessary for the Ministry of Education and its relevant departments to standardize the services of training institutions, provide effective guidance services for colleges and universities, and ensure the good application of computer multimedia technology in film and television post-production.
Concluding remarks
In the process of promoting the rapid development of the national economy, the film and television industry, an important representative of the tertiary industry as the leading force of the national economy, plays an active role. At the same time, promoting the wide application of computer multimedia technology in film and television post-production is also of great significance for improving the quality of film and television products, promoting the development of film and television industry, finally achieving stable economic growth and improving people's material and spiritual living standards.
