What's the difference between digital movies and ordinary movies? Who knows!

The so-called digital movie is a movie in which images are stored in digital form in containers such as hard disks. The advantages of this kind of film are that the film is not faded, easy to copy and low in shooting cost. But the shortcomings are also obvious and unclear.

At present, imax film movies are the clearest, followed by ordinary film movies, and then digital movies.

Digital movies are more popular, because it can avoid the aging and fading of the film caused by light source irradiation, ensure that the film will always be as bright as new, ensure that the picture has no jitter and flicker, have enough pixel stability, and the audience will never see scratches and wear like raindrops again. In addition, the distribution of digital film programs does not need to develop and print a large number of films, which not only saves the production cost, but also is beneficial to environmental protection. The guarantee of digital transmission technology is that the whole film will not lose quality during transmission, so that the audience can see the film exactly like the film director. In other words, once the digital movie signal is sent out, no matter how many digital cinemas there are on the earth, the same program can be shown at the same time. At the same time, digital projection equipment can also provide value-added services for cinemas, such as real-time broadcast of major sports competitions, cultural performances, distance education and so on. And make it the trend and direction of development in today's world.

The so-called digital film refers to the film and television works that are shot, produced and stored by digital technology and equipment, transmitted through physical media such as satellites, optical fibers, disks and optical discs, and the digital signals are restored to images and sounds that meet the film technical standards and projected on the screen. After the production is completed, the digital signal is transmitted through physical media such as satellite, optical fiber, magnetic disk and optical disk. And is restored by a digital player and projected by a projector. So as to realize film-free distribution and projection and solve the long-standing problem of high film production and distribution cost. Compared with traditional movies, the advantages of digital movies are mainly reflected in: saving film production costs, innovating production methods and improving production level. Through the high-definition camera technology, the integration with the high-definition era has been realized; Digital media storage, always maintain a stable quality, there will be no wear, aging and other phenomena, not to mention jitter and flicker; There is no need to develop film for transmission and distribution, so the distribution cost is greatly reduced and there will be no quality loss during transmission; If satellite synchronization technology is adopted, it can be attached, such as live broadcast of major cultural and sports activities, distance education and training, etc. This is beyond the reach of movies.

At present, foreign films dubbed in Chinese in cinemas are all imported by China International Radio and Television Company, which needs strict examination and approval, and then dubbed in Mandarin by a professional film translation factory. Most of these officially imported films are film versions. However, some English digital movies being shown in cinemas are usually movies that have not been officially introduced or the release date is synchronized with foreign countries and have not been dubbed in Mandarin. Because these films have not been officially introduced, most of them are transmitted to cinemas in the form of English original and Chinese subtitles and played by digital technology.

At present, there are two specifications of digital movies: one is the so-called "standard definition" movie, which is shot with standard digital video tape, and the definition is about 700 to 800 lines in horizontal resolution; The other is the so-called "high-definition" movie, which is shot with high-definition video tape, and the resolution is about 1 100 to 65438. Movies shot with digital video tapes can usually be shown directly in cinemas with digital projection equipment, which is called digital movies. Of course, movies shot in HD are better, but in fact they still can't reach the definition level of films. Sometimes, it is also possible to transfer the film shot by digital video tape to film and show it with ordinary film projection equipment. This kind of film is called "magnetic transfer adhesive".

Blockbusters are generally films with feelings.
