How to explain "numbers" in digital movies? Pray for the great gods.

What is a digital movie ● The film production process, production mode, distribution mode and communication mode are all completely digital. It can be regarded as a digital movie in a complete sense. ● Compared with traditional movies, the biggest difference is that digital movies are no longer distributed in the form of film, but in the form of digital files, or directly transmitted to end users such as cinemas and families through networks and satellites. Relying on broadband digital storage and traditional technology, digital broadcasting is realized through high brightness, high definition and Gao Fancha electronic projector. ● Digital film technology enters the micro-world. It decomposes the image into the smallest unit-pixels, and then recombines it, changing or reconstructing a part of the image and the scene, creating wonderful shots that ordinary photography methods can't achieve at all, and almost realizing arbitrary creation. ● The production process of each shot in 3D can be roughly divided into: making a physical model-scanning the model to get a sketch-computer modeling-restoring the texture-adding post-processing such as lighting and special effects to the rendering-synthesizing the picture to achieve the final effect. 2 Advantages, significance and prospects of digital movies ● Digital movies can perform brand-new sound effects surrounded by 5: 1 channel AC-3 sound, which greatly expands the performance space of movie sound and makes the appeal and shock of movie sound reach an unprecedented level; Judging from the image effect, the color is more vivid and full, and the clarity is greatly improved. Although the price of each set of digital film projection equipment is as high as 6.5438+0.5 million yuan, which is 654.38+00 times of the most advanced film projection equipment in the world today, digital film has changed the defects of bright in the middle and dark on both sides of the screen during film projection, and the uniformity is almost perfect. In addition, digital technology has created an extremely virtual space and all kinds of incredible scenes, which can not be expressed by ordinary film production methods. ● Digital movies have solved the problem of loss in the process of film production and distribution to the greatest extent. Digital technology, from the original shooting material to the 7-inch reproduction and distribution, has avoided the scratches on the pictures and vocal cords of traditional movies, and even after repeated screening, it has not affected the quality of sound and painting at all. ● The produced digital movies can be distributed on digital floppy disks or sent to cinemas all over the world via international satellites, which saves time-consuming and laborious copying and transportation. ● Digital film technology has greatly broadened the creative world of artists and injected new vitality into the declining film industry. 2 1 century, a new generation of artists with new thinking and emerging careers in the film industry, such as digital film software designers, computer art designers and visual effect designers, will become the protagonists on the film stage. ● Digital film provides a new historical opportunity for the development of film: digital film is a new world where film art develops its creative wings; The breakthrough of digital film in anti-piracy technology has given us higher protection technology; The nonlinear editing of digital movies is not limited by time and can be edited at will, which realizes the modernization of input system and picture processing. The leap of software, auxiliary equipment, output system and other technologies will bring a new look to traditional movies; In addition to the development of movies, game products and network products. It provides a rapid development space for artists in the digital film era. Movies have a history of one hundred years. Every progress is due to the promotion of technology, and digital technology has entered the film industry. It is the third revolutionary improvement after the film changed from silence to sound and from black and white to color. The involvement of digital technology will revolutionize the film from production to performance, operation, distribution and broadcasting. Although digital film will not be fully realized overnight, it will start the development of digital technology. ● Digitalization will have a far-reaching impact on movies-because digital movies can be transmitted by satellite, it will have a revolutionary impact on the film screening and distribution system. More importantly, the digitalization of film will fundamentally change the characteristics of this media form, and the digital film will no longer be the embodiment of reality, but enter a virtual space; It will be easier to edit and modify the film, and even realize an interaction with the audience: the audience can control the direction of the film by themselves, and the characters in the film can also communicate with the audience; The digital propaganda of movies has broken the material boundary with TV, Internet and video games. Online movies, on-demand movies and movie-style video games have appeared and will be more popular in the future. It can be said that due to the development of digital technology, various forms of entertainment will gradually merge. ● It is reasonable to predict the prospect of an industry in 2 1 century. 100% depends on whether its products or services can be converted into digital form. Human electronic technology has entered the digital age from analog digital, and a wave based on the smallest unit bit of digital information has begun. The means of obtaining information, processing information and transmitting information are becoming simpler and faster, and the movie, the wizard of images, cannot be avoided. More and more fantasies of producers can be realized on the computer as a dream-making tool, making movies more and more magical. With the appearance of digital movies, a visual revolution is taking place in visual image production technology. Visual media and mode of production have brought about such profound changes, which can be said to be a digital renaissance. The emergence of digital movies has a greater impact than the emergence of audio movies and color movies. 3 Background Understanding ● Digital film was born in 1980s, and it is a product of high technology. With the rapid development of computer technology, many shots that traditional movies can't complete need the help of computers, or the use of computer technology will make movies more perfect. Therefore, digital technology is introduced into traditional movies. Internationally, after the initial exploration, the digital film technology is very mature at present, and the creators have gradually changed from simply using digital stunts to integrating with traditional shooting and traditional stunts. In the United States and other countries, a large number of creative talents with modern digital technology and artistic taste have emerged, resulting in a large number of films with good audio-visual effects. In China, digital film was tried as early as six or seven years ago, but it really started after 1996 Changsha National Film Work Conference. At this conference, "digital film production" was put on the agenda solemnly, and was identified as the breakthrough of the future development of China film technology. After that, the state aimed at the world's advanced digital film production technology, invested a lot of money and introduced advanced technology and equipment. 65438-0999 The State Planning Commission approved the "Digital Film Production Demonstration Project" of the State Administration of Radio, Film and Television. ● The first full 3D animated feature film in film history was Disney's Toy Story, which lasted for 77 minutes. 156 1 3D lens was made by computer. It took four years to employ 1 10 staff and cost 30 million dollars. The first batch of digital cinemas in the United States appeared in May, 1999, and Disney Company produced the first filmless digital movie Toy Story Sequel. China's digital film is still in its infancy. The development of digital movies in China faces two dilemmas: economic problems, and it is still difficult to generate profits from the development of digital movies in China. Digital film has a large investment, high depreciation rate of equipment and high salary of personnel. The digital film industry in China is faced with urgent problems such as how to start a business, how to absorb foreign capital and "inject fresh blood", and how to realize a virtuous circle of input-output and commercial returns. In terms of talents, there is a lack of multi-level talents to develop digital movies in China. Artists in China pay too much attention to the division between technology and art, lack talents who know both art and technology, lack senior talents such as production directors, and lack strategic cooperation among digital film enterprises.
