4K technology highlights what the cinema server has done

In the digital age, 4K movies have gradually emerged. This digital projection system, which is 4 times the resolution of mainstream domestic theaters, has successively landed in major theaters across the country. What changes and challenges does this emerging digital film and digital content resolution standard bring to the Chinese film market? How should the cinema market seize this opportunity? With the prosperous development of the film market in recent years, everyone is no longer unfamiliar with the terms 3D and IMAX, but when it comes to 4K, I believe many people don’t know it well. The so-called '4K' is a resolution indicator in the field of digital movies. From a purely technical point of view, the resolution of the highest-level 4K movie is 4096×2160; and the current popular domestic digital movie projector is the 2K level, which has a resolution of 2048×1080. '4K' movie high-definition picture In general, the definition of 4K movie is 4 times that of the current mainstream 2K movie in China. The audience will be able to see every detail in the picture, and the viewing effect will be clearer, smoother and more lifelike. 4K digital movie in the true sense refers to a digital movie shot with a 4K camera and projected with a 4K projector. When using a 4K digital projector to project an image on a large screen, the typical 'shadow' phenomenon will disappear, and you will never see individual pixels anymore. When using a 4K digital projector to project an image on a large screen, the pixel structure will not be seen even when viewed at a close distance of 1 times the height of the screen. The high-precision and delicate images are more full of various colors and lights, and even the flames in the movie seem to really make people feel the heat wave. 4K projection equipment in the digital age and the rapid advancement of digital cinema technology. The combination of 4K movies with the 4K giant screen gives the movie a stronger sense of substitution. Under the size of the giant screen, the fineness of the 4K picture performance is not as sharp as that of a TV or monitor, but in fact, in high resolution With the support of the rate, the details of the faces of the characters and the dark parts of the overall scene are more obvious. The status quo of 4K applications in theaters In the past, when film copies were shown, the staff could carry the copies to the theater and show them directly, but the operating procedures for 4K digital films were much more cumbersome. After the copy is obtained, the content on the master hard disk needs to be uploaded to the projector. Because 4K digital movies are clearer than ordinary digital movies, and their source is larger, this means that a two-hour movie takes 3 hours or more to upload, which makes the projection technology more complicated. The emergence of 4K servers completely eliminated these technical barriers. But on the other hand, we must also be soberly aware that 4K is still in the high-end market in China, and the penetration rate is very low compared to the raging 4K movie screenings in North America. There is no doubt that 4K is the future trend, and now the price of 4K projection system has dropped to a position similar to that of 2K. Conclusion: As consumers have higher and higher visual requirements for movies, 2K can no longer meet the visual needs of ordinary viewers, and projection equipment that supports 4K digital movies has become the mainstream configuration. After entering 2014, major first-tier cities began to invest in 4K projection equipment. Sony, Barco, and NEC all have related engineering projectors that have begun to use. The cost gap is not too sensitive to cinema investment, but the excellent picture created by 4K can establish a unique competitiveness. The cinema will naturally tend to more advanced 4K products when adding new screens. The construction of 4K cinemas in China is rapidly starting. In the next five years, China's new digital screens will account for more than 90% of the market. We can also foresee that in the near future, it will be: no 4K, no cinema!
