How aggressive is 1120FPS/3D/4K/28fL? Back to top [PConline Info] "Billy Lynn's Midfielder" If you haven't had time to look, it's estimated that you've heard that the 120-frame/3D/4K film technology revolution has been pushed into the limelight. How shocked? I'm sorry that there are only cinemas in Beijing and Shanghai that support this screening standard in mainland China. Xiao Bian in Guangzhou can only go to Wanda to experience a 60 frame/3D/2K version, although the effect of a discount of two, but used to 24 frames of 3D movies to experience 60 frames of 3D, also shocked to let I remembered for a long time and lamented that this is the real movie. The use of such high-standard technology is a great challenge to the structure, description, and performance of movie stories. With such a clear and high-speed capture, all kinds of embarrassment become hidden. Instead of focusing on portraying the magnificent scenes of war, Li An vividly captures the emotions of the characters and describes the truest human nature as a documentary in the simple narrative of moderation. The views on family, wealth, love and death have left blank and deserve the audience to ponder. If you are a partner of Dalian, Chongqing, Jinan, Changchun, Nanjing, and Changsha, you can also experience the 120 frames/3D/2K version of this movie. (Why didn't Guangzhou Shenzhen!!) How aggressive is 120FPS/3D/4K/28fL? In 3D and 4K, most of these two elements have been experienced, but 3D 4K movies do not show much, let alone 120 frames/3D/4K. Li An is not technically controlled. From the "fairy drift of the juveniles," he used 3D photography for the first time. However, he also started to complain about the 3D of 24 frames. After wearing 3D glasses, the screen shakes badly and the overall brightness is high. And the details are also greatly reduced. So he started brewing this "Billy Lynn" generous. It may not feel much to see this series of parameters without comparison. If you know that the 3D movies we normally watch are 24 frames/2K/4.5fL (fL, Ford Lamberts, the unit that detects brightness), then you know Billy Lynn's 120 frames/3D/4K/ How aggressive is 28fL? 120FPS The number of frames is well understood, which is a few frames per second. The film art has always been called the "24-truth truth" not because the human eye can only perceive the picture of 24 frames per second. The gods who play CS all know that to turn off the vertical synchronization and brush to 100 frames, the conditional reflection of people is far. Far more than 24 frames. But why did the 24 grid movie stay in the film history for so long? The reason is actually very simple. In fact, technology can already be used to achieve higher-frame-rate movies. However, movies such as commercial art, from production to distribution, are often subject to cost and effect constraints, and there are many compromises. Especially in the previous film era, the number of frames was directly linked to the shooting cost, 60 frames per second, the cost of the movie was doubled, and the projection equipment also needed to be upgraded. The effect of the upgrade was driven by the upgrading of consumer viewing. In a short time, it can't fill the gap of production costs, so no one intended to pick up this pot. Even in the digital age, the huge amount of data is very painful. A 24-frame/3D/2K movie data processing system is thousands of terabytes, like "Billy Lynn," an unprecedented large-scale movie, and even a device and software can do it at 120FPS to edit it. Finally, you can only import 60FPS to edit the clip and then compare it to the 120FPS version. Is the difference between 120FPS and 24FPS really great? The difference is of course great, especially for 3D movies. The higher the frame rate, the more pictures per second are stuffed in, the smoother the look, the more realistic the motion of the movie. When you are accustomed to the 120-frame movie, you will feel that 24 frames are always awkward. The timing of this year's 120-frame movie by Li An should be just right. The "Hobbit 1: Unexpected Journey" released in 12 years adopted a standard of 48 frames per second, which is a big impact on the film industry and bred the seeds for the development of high frame rate movies. However, in the Chinese market, which had reached 21.7 billion yuan at the time of the box office, there was no theater capable of showing the highest specifications of the movie. Only 5 Cinemas Worldwide Can Display 120FPS/3D/4K Versions Today, Li An recorded the movie with 120 frames per second, creating a new door for commercial movies. The top five countries in the world that can show the highest version of China occupy three (Shanghai, Beijing, and Taiwan). One can imagine that with the development and popularization of technology, the 120-frame movie will be accepted and loved by the general public. 4K Talk about 4K for several years, but the current popularity of 4K movies is still very low. Even if smart TVs are all 4K or even 8K, most of the video content transmitted to TVs is only 1080P. Most movie theater equipment only supports 1.5K-2K. In 2014, major Tier 1 cities began to deploy 4K projectors. Until now, there are only one or two 4K studios in large-scale theaters. Projector standard resolution Most of the crew shooting films have been used 4K acquisition equipment, 4K/3D post-processing has gradually improved, the masters are also out of 4K, but because the major mainstream theater is still about 1.5K-2K projector Therefore, the movie distributed to the cinema is only 1.5K-2K. It is still a matter of cost. Old equipment updates will inevitably cause heavy theater bleeding. However, old equipment can still be "enough to use," so the speed of equipment replacement is still very slow. If you haven't experienced 4K video in the movie theater, but you've definitely seen a 4K TV demonstration in the TV market, the picture will certainly be awesome. Especially on a screen as large as a movie theater, the difference between 4K and 2K resolution is obvious, and the resolution is much higher. 2 Immersive movie experience still has many deficiencies back to the top 28fL The fL Chinese name is Ford Lambert, which is the unit of brightness detection. I remember that in the 15 years when "Speed ​​and Passion 7" was released, many netizens complained that the movie's screen was dark and looked very uncomfortable. That's because the brightness of the projector lamp is not enough. Currently in the movie industry, the 2D brightness standard is 14FL. During the 3D screening process, the brightness is lost due to various technical reasons. The current standard is set at 4.5FL in the industry, but most of the current domestic 3D movies can only reach the brightness of 3FL. . The RealD company certified 6fL standard was promoted in Hollywood movies. Some advanced cinema projectors allowed 3D movies to meet 6fL standards. The highest version of this "Billy Lynn" reached 28fL, which directly increased brightness by almost 5 times. The tolerance of 3D movies was greatly released. The details of the picture can be clearly seen in the darkest place and the brightest. This is a bit like the HDR technology of the TV industry this year. Why does the average movie theater have a lower brightness when showing 3D movies? Is the brightness of the lamp lowered in order to save the cost and extend the life of the lamp? This problem cannot be explained as simple as that. The xenon lamps commonly used in movie theaters are high-risk items, and there is a large risk of exploding lights when they are used overtime. When the lights are blown, the instrument can be damaged. If used under high brightness and high power consumption, the risk is even greater. Technical reasons are bound to make high-brightness movie screenings become mainstream. So with the 28fL top projection effect of "Billy Lynn", only five cinemas in the world can reach the standard. Immersive movie experience still has many shortcomings The development of film technology has gone from silent to sound, from black and white to color, from a square screen to a widescreen, from 2D to 3D. The movie is really amazing. It is not only a discipline that blends art with humanity, but also an important representative of the progress of digital media technology. From the history of the development of film technology, it is not difficult to find that every change is constantly promoted around the audience's perception experience. From the various aspects of sound and picture quality, it continuously fits the human sensory characteristics, and the ultimate goal is to achieve the same effect as seeing it from the screen. This effect can also be called an immersive experience. Whether it is the current hot VR, AR technology, or the 120FPS/3D/4K/28fL technology described in this article, it is to create a more immersive experience. But after all, movies are the art of living and the thinking of human nature. This kind of artistic behavior will undergo some changes in the way of expression because of technological progress. But will such changes always be positive? Maybe not necessarily. If you read a book and listen to a story, you can also burst into tears or laugh with watching a movie. With a bunch of strangers gathered in the studio, looking at the repetitive pace of the movie, the back, or the smashing cigarettes, you can stare for a long time. At this time you can't think of the quality of the picture and can not think of color, but there is still a feeling of empathy. The immersive film revolution has just emerged and it is somewhat embarrassing. The picture that 120FPS/4K can record is too realistic. Therefore, it is required that the actor's fictitious things such as performances, makeup, costumes, and props be flawless in order to achieve the effect that the film art must convey. For example, do you mind seeing the foundation of Fan Bingbing's face in the movie, or the margin of the costume drama wig? Excessive realism fails to filter out details that we don’t care about, focusing on the movie itself. It is not that the evolution of technology is wrong, but that the director and the actor who uses technology must also evolve in the way of expression. Technology can help the film to better express art. "Billy Lynn" is such a bold attempt. To tell the truth is insufficient in many places, but such exploration is very worthy of recognition. There are also directors who are trying VR movies. I don't think that this kind of closed immersive experience can replace the movie theater projector. Even if the VR resolution is higher and the delay is lower, the art form it can express is always limited. Of course, maybe it is not trying to eliminate who, it just adds a new possibility. In summary: Xu Zhiyuan interviewed Li An in the recent issue of “Thirteen Invitationsâ€. Xu Zhiyuan asked, do you worry about your gentle personality and prevent you from making deeper explorations? Li An replied that the arts incident should not be completely erupted. The best sense of balance is to leave room for it. There is a space for recollection. It is not only that you are out. The audience also scores in half. Not only are you out of strength, the audience also scored in half. And I want to say that the strength is not only technical, but also art has to account for more than half.
