Keywords: 3D 4D digital stereo technology TV media
The continuous development of technology, the innovation of the media, and the rapid popularization of the Internet are quietly changing the classic model of mass communication. In this era of rapid economic development, people have unprecedentedly experienced the "explosive" impact of technology on life. Today's society has shown the characteristics of diversity, cultural diversity and value diversity. How can mass communication meet the growing audience The more diverse and demanding requirements have become a deeply pondered issue for film and television media. Nowadays, when television people complacently realize the digitization, lithography and high-definition of television media, the digital stereoscopic display, restoration and perception of the real world in movies have entered the eyes of the audience, bringing unprecedented visual impact and experience to the audience. Today, with the increasingly fierce competition in mass media, digital stereoscopic movies 3D and 4D have become a new trend in the film and television media.
A few days ago, the 4D urban stereoscopic film "The Nickel Capital of the Motherland", which was invested by Jinchang City, used the new stereoscopic film shooting technology, all of which were shot in real high-definition, and then processed and beautified by computer post-processing. City Promo. The use of digital stereoscopic technology to shoot city publicity films to create a brand new city display and publicity platform, which is the first in the west, has also become a new form and innovative thinking of the national publicity city business card. It allows us to feel the charm of digital stereo technology shooting TV propaganda films, but also allows the TV media to more or less feel the impact of stereo digital technology on the audience. Will digital movies 3D and 4D become the largest TV media in the near future? Competitors, popularizing digital stereoscopic display, restoring and perceiving the real world, has the television media become a new fashion with prominent encirclement like movies, or the "killer" and the next revolutionary task with its peers.
1 Digital stereo technology, TV media meet new challenges
(1) The development history of stereoscopic film Internationally, stereoscopic film is represented by 3D film. D is the prefix of English Dimension (line, dimension), 3D refers to three-dimensional space. In 1953, in order to compete with TV for viewers, Hollywood launched a new play-three-dimensional movies, audiences with special eyes like watching thrillers such as "The Devil of Bowana" and "The Labu", found Hiding behind the escaping train and the devil, brought us into the era of stereoscopic movies. So far, the film has ushered in a major revolution and entered a new era of development. Although 3D stereoscopic film technology has been around since the 1890s, so far, neither 3D movies nor 3D projection facilities have become a reality. But in recent years, some foreign film and television companies and visionary big directors have used this new technology, and their joint efforts seem to have kicked off the renaissance of 3D stereoscopic movies. Since the first launch of the digital stereoscopic film "Chicken Run" by Disney in November 2005, more than 10 digital stereoscopic films (all of which are animation, science fiction, and adventure themes) have been produced around the world. Chang is generally the same as ordinary feature films). Over the past two years, more than 1,500 digital stereo screens have been installed in the world. This special type of movie is loved by audiences from various countries as soon as it is launched in commercial theaters. Although the price of digital stereoscopic movies abroad is higher than the price of ordinary movies by $ 1-2.5, the number of people watching movies is far higher than ordinary the film.
It is believed that the leap from 2D plane to 3D stereoscopic film will become the third revolution in the history of film, just like the progress from silent to sound film, black and white to color blockbuster. No matter in the eyes of the film company or the director, from the 2D plane to the 3D stereoscopic film, the 3D film has become the future of the film, at least in the short term.
(2) Basic concepts of 3D and 4D movies
Stereoscopic film refers to a stereoscopic film produced by dual camera shooting and three-dimensional technology and used for stereoscopic theater playback. 3D stereoscopic cinema——On the basis of ordinary projection digital movies, when the film source is produced, the source image is displayed with two left and right eye dislocations. Each channel projection screen uses 2 projectors to project related images, through polarized lenses and polarized glasses. The left and right eye images of the film source are respectively projected onto the left and right eyeballs of the audience, thereby generating a stereoscopic presence effect. As we all know, 3D theaters (often called stereoscopic movies) have decades of history.
4D theater-4D theater is relative to 3D stereo theater. It is based on 3D stereo theater and various special effects surrounding the audience, called 4D. In recent years, with the development of video entertainment technology and the needs of the entertainment market, people not only introduced special effects such as vibration, falling, blowing, water spraying, and scratching into 3D theaters, but also carefully designed smoke, rain, photoelectricity according to the plot of the film , Bubbles, smells, scenery, character performances and other effects, forming a unique form of performance, this is the very popular 4D theater today. Due to the development of movie plots combined with various special effects in 4D theaters, the audience can get a full range of visual, auditory, tactile, and olfactory feelings when watching 4D movies.
In recent years, the development of 4D cinema has been very rapid, and the performance form of 4D cinema has also been greatly developed according to people's increasing entertainment needs. At present, the 4D cinema with flat screen mode is being impacted by the round screen mode, and the new stunt seat With the dynamic platform, 4D cinema has entered a new stage. After entering the 21st century, large-diameter, multi-screen cylindrical 4D theaters have gradually become mainstream. In particular, the emergence of cylindrical screen 4D cinema, various dynamic platforms, rotating platforms, and railcars also entered the theater according to the plot, becoming the most rapidly developing 4D cinema type today.
(3) The production principle of stereoscopic movies
There are many forms of 3D stereoscopic film production, among which the polarized glasses method is more widely used. It uses the human eye to observe the scene, and uses two movie cameras arranged side by side to represent the left and right eyes of the person, and simultaneously shoots two movie images with a slight horizontal parallax. During the projection, the two movie films are loaded into the left and right movie projectors respectively, and two polarizers with a polarization axis of 90 degrees to each other are installed in front of the projection lens. The two projectors need to run synchronously, and at the same time put the picture on the metal screen to form a double image of the left image and the right image. When the audience puts on special polarized glasses, the polarization axes of the left and right polarizers are perpendicular to each other and coincide with the polarization axis in front of the projection lens; therefore, the left eye of the audience can only see the left image and the right eye only The right image can be seen, and the left and right images are superimposed on the retina through the convergence function of the two eyes, and the brain nerve produces a three-dimensional stereoscopic visual effect. Displaying a series of coherent three-dimensional pictures makes the audience feel that the scene is coming, or entering the deep recess of the screen, which can produce a strong sense of "presence".
(4) Digital stereoscopic movies and TV media meet new challenges
Technology is spawning new things. Needless to say, high-tech movies have been accepted by more audiences, and movies are about to enter the 3D era. The cinema already has the ability to introduce such advanced 3D digital projection equipment, and the use of such projection equipment can display effects far beyond ordinary movies. Digital images can show more vivid images, or they can be completely three-dimensional. It is understood that the past 3D movies were film screenings, but now all use digital technology. Compared with the traditional film stereoscopic film, the digital 3D film has clear, stable, no obvious ghosting and high brightness, and the audience will not feel dizzy and tired when watching for a long time.
TV media has entered the digital age today. Despite the realization of digital high-definition, whether digital stereo is the direction of future development and the goal of efforts, we dare not assert. However, the shock and visual impact that 4D movies bring to the audience is currently out of reach of digital TV, at least incomparable. The audience's choice is the "touchstone". It should be said that the increasingly fierce competition in TV media programs today welcomes 4D The challenge cannot but be said to be a real problem facing our TV media.
2 City Stereo Propaganda Movies: New Ideas for Film and Television Media Propaganda
(1) A new vision of urban publicity
With the development of the times, the city publicity film as a unique form has received more and more attention from politicians around the world. It is used as a means and method to promote the city, promote the city, create a city image, shape the city brand, and attract foreign investment. They have appeared on screens, flooded with TV media and the Internet, attracting the attention of the world and becoming a beautiful landscape. Even some exquisitely produced propaganda films have played the role of beautifying the city and packaging the city. After the TV media was broadcast, the city's reputation rose and achieved good publicity. City publicity films have also become a city's "gateway" and "business card", which has played a very important role in enhancing the city's popularity and promoting local economic development.
Jinchang is an emerging industrial city founded in 1981, and it is also the “nickel capital†of the motherland. After more than 20 years of development, urban construction is changing with each passing day, and various social undertakings are flourishing. Achievements that have attracted worldwide attention have been achieved and become a bright pearl embedded in the Hexi Corridor. However, because the city is located in the underdeveloped northwest region, its popularity at home and abroad is not very high, and some people do not even know that there is a "nickel capital" Jinchang in the great northwest of the motherland. The investment of Jinchang City to shoot urban stereoscopic videos was very high from the beginning. It was a stereoscopic digital film, and the length of the film was 12 minutes. Taking full advantage of the hardware conditions for 4D cinema stereoscopic film playback, we used a new vision and the latest digital stereo. Film shooting technology, creating a new image of the city, has become the first in the northwest region to promote the city, breaking through the visual impact that TV media can not achieve, and will definitely add icing to the city promotion.
(2) Propaganda themes with distinctive features
The rise of urban publicity films in the TV media has only a short period of more than ten years. It can be said to be in the ascendant. It has a strong political color and historical background. It is a "killer" for governments to promote cities, display resource advantages and attract investment from merchants. "In a specific historical period, it played a very good role in propaganda.
The three-dimensional city promotional film of Jinchang closely follows the theme of "China's nickel capital? Charming Jinchang" and promotes Jinchang's "motherland" nickel city as a unique city brand to show Jinchang's "emerging modern industrial city" and "Gobi oasis city" Vitality and vitality are two key points of performance, showing Jinchang's resource advantages from all angles and angles. The film adopts Jinchang City's overall introduction to the specific narrative resources of each city's specific advantages, and assists 3D special effects and stereoscopic special effects lenses. Intuitively showed the audience an emerging industrial city and Gobi ecological oasis-the new Jinchang.
(3) The art form of new technology
At the end of the 20th century, the continuous advancement of digital technology has made a great breakthrough in the creative space of film and television arts. Nowadays, new media and new communication tools based on digital technology are emerging one after another, which not only saves the cost of film and television production, but also lowers the threshold for people to participate in artistic creation. The shooting team of Jinchang City Stereoscopic Propaganda Films-Shuhu Image is the only institution in China that is engaged in the production of stereoscopic film. Shuhu Image has been working closely with the Digital Technology Research Institute of Beijing Film Academy since 2001 to become a domestic professional stereo film shooting and production company. The company has a number of technical patents in three-dimensional output software, multi-screen stitching, surface correction, synchronous playback and so on. At the same time, it also has the most professional shooting equipment and film crew in China, and all the films are filmed with a film-grade film machine. In the process of shooting publicity films, there is no trace of movie film. The stereoscopic digital camera greatly reduces the production cost, making the film and television art break through the traditional creative space, and the personality of the digital stereoscopic image is prominent. In the creative process, the film crew used real-world stereo shooting to make the visual effect truly shocking and extremely experiential. Combining computer three-dimensional animation and special effects technology, more angles, more techniques, and more levels will be used to show the characteristics and advantages of Jinchang City. Through the three-dimensional display, the better overall image of Jinchang City is presented to the audience, leaving a very deep impression.
(4) Unique creative methods
New technologies continue to challenge art forms. The realization of the interaction between art and technology is a significant feature of Jinchang's three-dimensional city promotional film "Nickel Capital of the Motherland". As a brand new type of city publicity film, the publicity film produced with the TV media will have a greater breakthrough and realize digital stereo shooting. The style of the whole film is fixed in the three-dimensional real shooting + computer three-dimensional motion + painting special effect technology. The perfect combination of technology and art makes the style of the film have distinctive characteristics and cultural heritage. It has a novel concept, a high starting point, strong artistry, bright colors, simple and bright, clear rhythm, full of vitality, and strong visual impact and appeal. . The beginning of the film is the beginning of the film, using full three-dimensional animation production technology, showing the audience a magnificent Northwest Pearl-Jinchang City. A large panoramic picture is quickly advancing from space to space and moving between the nebula. The camera then advances from the universe to the Chinese territory of the earth, and then quickly advances to the overlooked Gansu Province. The picture is pushed from Gansu Province to Jinchang City again. The passionate music keeps moving forward. The title starts with the order of space, crosses the universe to overlook the Chinese territory, advances to Gansu, and advances to Jinchang again. In just 10 seconds, it is very eye-catching and combined with passionate music, it makes people seem to find it through the universe. Jinchang City. The bold and artistic vision of the opening titles also gave the audience an intuitive impact from the beginning.
3 New media operation model and creative thinking, TV media adapt to a new perspective of competition
The economy is prosperous and all industries are flourishing. In today's era, with the rapid development of the economy, the global media has undergone rapid changes, and reform and development are in full swing. In particular, new media spawned by some new technologies have shown their talents in the tide of the market economy, making the increasingly fierce competition of film and television media under unprecedented pressure and challenges. Especially today, with the development of TV media industry as a group, professionalization of TV channels, and increasingly fierce program competition, as some local TV stations with small development scale and weak strength, they re-examine themselves with new thinking and new perspectives. The wise move of the TV media to highlight the encirclement.
One of the revelations, take the initiative to attack: a new way to enhance the self-worth of film and television media.
In order to make good filming of city publicity films, before the Spring Festival in 2009, Jinchang City publicly tendered to the public. In early February, a tender meeting was held at Jinchang TV Station to determine the filming unit. The image of the number tiger as a bid can be said to be prepared. After all the preparations, the wonderful creative planning, the exquisite city publicity script, and the picture display of the creative equipment stand out among the peers and become the contracting unit. As peers in the media, we not only appreciate the successful creative planning, but also see the new operation mode and development potential of emerging media. Being prepared, taking the initiative, and winning the initiative has enabled them to realize the self-worth of the media. The reward of a city publicity film is far higher than our imagination, and it is dozens of times that our TV media does the same type of publicity film. As a local TV media, there is indeed a certain gap compared with it. Especially, our TV media in remote areas in the west have problems such as lack of a strong sense of market competition, being wealthy, being full of the status quo, and lack of talents. Unfavorable factors, actively changing ideas, implementing the strategy of going out, and taking the initiative to win the market should be a new way for our local television media to adapt to competition, improve self-worth, and achieve reform and development.
The second enlightenment is the market operation mode: the basic requirements for film and television media to adapt to competition.
From bidding to contract signing, to organization shooting, the completion of the production of Jinchang City's digital three-dimensional city promotional film is a process of market operation of TV media and emerging private media. From contract signing to filming and production completion, both parties abide by the contract Powers and obligations. The signing contract made specific and clear requirements on the realization goals, technical content, shooting requirements, production requirements, broadcasting methods, viewing methods and copyrights of the digital three-dimensional city promotional film. The shooting fee is also paid in strict accordance with the shooting process to ensure normal shooting and production. Due to the pure market operation mode, the commercialization of film and television media products has been truly realized, effectively improving the quality and value of the products. During the specific shooting operation, the film and television company also strictly follows the market-oriented model. The bidder, project leader, and film crew each have their own responsibilities and are a "team" and a complete set of "human horses." , With strong professionalism. As well as personnel use and equipment leasing, it is also a complete set of commercial operation mode, strictly according to budget.
The third revelation is unique creative planning: an effective means for film and television media to build a brand.
Innovation of creative concept. A successful promotional film, unique creative planning, all play a leading role, it is the soul and theme of the entire film. Good creative planning is an art, and appreciation is even more enjoyable. The creative planning of the digital three-dimensional city promotional film "Nickel of the Motherland" is worthy of our TV media's reference and learning. The film closely follows the theme of "China's Nickel Capital? Charming Jinchang" and shows Jinchang's "emerging modern industrial city" and "Gobi oasis city" with new concepts. There is a big difference from the creative planning of the promotional films we have shot in the past. It is not large and complete. "A big basket is filled with everything", but it gives the Gobi city a distinctive feature based on local reality and characteristics. "The whole film recounts this unique feature, making the theme of the propaganda film distinctive and full of the atmosphere of the times. Through the creation of creative ideas, the city has formed a unique publicity brand.
The innovation of picture art. Film and television is the art of audiovisual combination. The picture comes first, and the explanation comes later; the picture is the main, and the explanation is the supplement. The two complement each other and complement each other. The digital three-dimensional city publicity film "Nickel of the Motherland" takes the "beauty" of the picture and the impact effect of the three-dimensional film as the style pursued by the entire film, and realizes the innovation of picture art. The beautiful picture of the whole film highlights one characteristic: it is dynamic and shocking. Each shooting scene reflects the creative planning of the director, and the composition is ingenious and exquisite. When filming Xinhua Avenue, the director asked the street to be cleaned and trees sprinkled before shooting. During the filming process, the street was subject to traffic control, and dozens of luxury cars were rushed to the mirror. Through the director's creative planning, the beauty and artistic conception of the picture are well increased, and the characteristics of modern city and three-dimensional impact are well reflected.
Enlightenment No. 4, a variety of artistic means: enriching the expression of the propaganda film and realizing the re-creation of art.
The mass media have their own advantages due to differences in media. But the first mover advantage in technology is an important winning factor in the competition of audiovisual media. Digital stereoscopic movies have been popular all over the world for a time. One important reason is that it has digital stereoscopic shooting technology, which makes print media incomparable. The use of high technology has injected new vitality into the art of film and television. One of the first features of the digital stereoscopic city promotional film "Nickel of the Motherland" is the use of stereoscopic film shooting technology to express the propaganda theme, and the perfect combination of technology and art. It uses two SONY-HDW-790 high-definition camcorders to focus and shoot at the same time. The picture art shown is rich in layer and dynamic, and it is a wonderful feeling of being on the scene; secondly, in the process of this shooting, Give full play to the advantages of technology and equipment, to re-create the art, using Canon high-definition wide-angle lens, rail car, rocker and other shooting equipment, so that when watching the promotional video, if the audience shuttle through the middle of the screen, from different angles to enjoy watching . The third is the use of three-dimensional animation stunts. The film and television program is very inclusive, and it can integrate a variety of symbols including text, sound, visual elements and so on. To artistically express the theme of publicity, in addition to the picture elements provided in the pre-shooting, post-production can further provide supplementary elements. In a sense, the use of three-dimensional animation special effects makes post-production more artistic than pre-production. This special effect is used extensively in the digital three-dimensional city promotional film "Nickel of the Motherland", so that some special pictures and special angles that cannot be achieved by ordinary shooting methods are reproduced in the form of three-dimensional animation, which gives visual freshness and enhances the picture. Artistic expression. For example, Jinchang's new airport, repaired people's cultural square, high-tech development zone that has begun to take shape, and the opening and ending of the film all use 3D animation technology and special effects technology, reflecting the pursuit of detail and picture art in the promotional film.
