"Teacher Lin, what do you think of this?"
Then a computer software that Lin Han didn't understand was used for the final synthesis and correction, and the coherent dynamic image was integrated with the background. After all the employees saw this semi-finished product, they were so surprised that they were speechless for a long time!
Many viewers think that bullet time is about shooting bullets breaking things or in slow motion. This view is wrong!
To put it simply, time is restricted, but the concept of space is free. It's very expensive to capture this kind of footage, either with an ultra-high-speed camera plus a robotic arm, or with a camera array.
In front of the green screen, Chu Guang, who was wearing a black windbreaker, had an extremely small steel wire hanging from his waist. Without the help of Wia, he would not have been able to perform those difficult moves. This is the legendary "Iron Banqiao" posture!
…
Now you can simulate the best solution directly on the computer, saving time and money!
The stronger the enemy, the more motivated Lin Han is. No matter whether he wins or loses, he just needs to shoot the movie to the extreme, and leave the rest to the audience.
The entire crew was mobilized for Lin Han's idea, and the actors were all happy and relaxed. At least they didn't have to work too hard, but Chu Guang couldn't.
Lin Han knew that there were about five ways to shoot bullet time, but he had never tried it. After all, he was just an ordinary reader in his previous life.
Lin Han touched his chin and asked, "How did you do it?"
Lin Han smiled bitterly and said with emotion: "This is not taking pictures, this is burning money!"
At the shooting site, these Nikon cameras were neatly arranged, with wires of different colors extending from each camera, which laymen couldn't understand at all.
Zhao Yuankun patted his head with his hand, and said to himself: "Theoretically, it is possible. It can be achieved by using many solar cameras to release the shutter at the same time as the actors perform, capture the momentary images, and then continuously project them. . But we don’t know how many cameras we need, how many pictures we need to take, and what angles and directions we need to take the pictures. It won’t work if we don’t solve these problems!”
…
Tang Rui was already busy quickly at this time. He used image mode to identify the photos he had just taken, and virtually repaired the differences between the photos in two adjacent chapters. After rendering, he generated coherent and smooth movements of the subjects under the 360-degree lens. !
In the starting position, this high-speed camera accurately captured the posture of the bullet flying in the air. The high-speed camera with a speed of 12,000 frames per second is very powerful!
In terms of visual effects, this is actually a disguised slow motion. It uses normal camera speed to show high-speed actions such as bullet flight and fighting. So it seems that these actions have slowed down, but ordinary people not only cannot feel it Procrastination will infinitely expand the sense of speed!
Hundreds of cameras are precisely placed on a route set by a computer tracking system, and shutter controls are centralized to facilitate the selection and adjustment of shooting moments.
The camera shutters that surrounded Chu Guang in a large circle began to ring one after another, and they began to take pictures according to the computer's pre-programmed program and time interval.
Right now, the scene they are about to shoot is the famous bullet time, but except for Lin Han, the others don't know how shocking this shooting method will be to the world.
This is the benefit of the technological age. If there were no computers, how much film would be wasted if we just started shooting
Not slow motion, better than slow motion!
So shocking!
"Don't even think about it. I shamelessly rented these cameras. One click and a hundred thousand dollars are gone. But the effect is really good, very beautiful, and it can stop time completely! This is unmatched by other shooting methods. of."
Tang Rui was not impatient at all. He slowly and carefully debugged according to Lin Han's requirements. It took a whole day to finalize the shooting plan.
In these few seconds, a lot of film was consumed, and Lin Han felt distressed at the money burned.
Lin Han snapped his fingers, "Now that computer technology is so advanced, we can just find someone to make a computer model for analysis. Everything is possible in the computer age!"
It’s simply an epoch-making idea!
Isn’t this easy to handle
"Actually, I have a better idea. Do you think it is feasible to place a circle of cameras over the green screen, let the cameras quickly capture each shot in succession, and then post-process these shots?"
This is the foreign aid specially hired by the crew. Expert Tang Rui was invited from the Computer Research Center of Tsinghua University. In the 3D software, he placed multiple cameras in the 3D space according to the set trajectories, and then selected each camera from the 3D space. The location generates a virtual picture, and after they are continuously projected, the effect of scheduled photography is obtained.
"What is the name of this shooting method?" Xu Jiayan said blankly. He only regretted that he was not Chu Guang and could not enjoy such treatment.
Xu Jiayan breathed a long sigh of relief, "With so many cameras, the cost must be very high, right?"
Only spatial displacement with extreme time changes or no changes is bullet time!
Lin Han used a video camera to record Chu Guang's performance in front of a green screen, and then sent the image to the computer. The software analyzed Chu Guang's movements and created an actor model of him!
The 122 Nikon cameras took photos at an average speed of 300 frames per second. Each frame of the image was scanned into the computer for processing. It was only a blink of an eye, but a lot of photos had been taken!
These shots magnify the action time of a moment. Such a picture is presented to the audience. Lin Han can lead the audience to appreciate this moment from all angles!
"You deducted our salary just for fun. I have been filming for so many years and I have never seen any crew shoot in this mode. What should I do if I suddenly want to experience it?"
This is the role of the director of photography, to provide the director with professional knowledge in photography. Lin Han does not expect to be an all-rounder!
Lin Han was just talking on paper now. This method was something he had seen in his previous life. He didn't know exactly how to use it, how many cameras should be placed, and how to make these cameras start shooting quickly, so he had to ask Zhao Yuankun, a professional.
In front of the green screen, the imposing Chu Guang was a little nervous, because there were too many cameras around him, and even a celebrity had never seen so many.
Early the next morning, Lin Han came to the studio. He had been filming this scene in his dream last night, and now he couldn't wait to rush to the scene to film it.
After the preparations were completed, Lin Han took the loudspeaker and shouted: "Attention all departments, the filming will start soon. Please step back for those who have nothing to do with it! Chu Guang, are you ready?"
Xu Jiayan, who had no role for the time being, stared at this posture in stunned silence. He turned and asked Lin Han: "Director, how many cameras are there here? It's so scary!"
The large electric fan in front of Chu Guang began to whir. In the studio, the only way to create the feeling of a windbreaker fluttering was with an artificial wind source. As the wind picked up, Chu Guang slowly moved slowly with the help of the pressure. Lean back and the bullets start!
The most important thing is that he is not sure that this shot is in place, so he has to wait for the computer to process the results before making preparations for reshoots.
"Director Lin, I really can't achieve the effect you mentioned." Director of Photography Zhao Yuankun said with some confusion. He tried several times, but it didn't work at all!
Originally, many employees were curious about how to film Neo dodging bullets, but after seeing Lin Han's creative filming method, they were all shocked!
When Lin Han watched this movie, he was shocked by the amazing creativity of the Wachowski brothers. Neo slowly leaned forward to avoid bullets in the rotating camera. For the first time, people really saw this. As for the movement of the bullet, you can see the 360° panoramic scene of the bullet rotating when it is stagnant. The slow speed is used to reflect the speed. The effect and visual impact are enough to make people remember it deeply.
Of course, the most classic shot in this movie is the magical "bullet time", which is famous throughout film history.
Judging from the scenes in the movie, Neo seems to have broken through the limitations of gravity, and his entire body is parallel to the ground. This backward posture paired with the flying windbreaker looks crazy and cool. !
"Taiwan 122." Lin Han, who was checking the monitor screen, replied without raising his head. This was the result of the crew working hard for two hours early in the morning!
Lin Han's whole heart relaxed, and he replied: "It's called bullet time. You will often see it in movies, TV series and even advertisements in the future!"
What is bullet time
Zhao Yuankun pointed to the shooting scene not far away, "I tied a small transmitter to the camera so that the camera can move very fast."
Today's audiences are different from the past. They know how to distinguish the quality of movies and will not blindly follow the trend. Their tastes have become more picky, so what Lin Han has to do is to put his conscience in front of the audience!
This unrealistic view of time can actually be integrated into the story background of the movie, forming a unique visual impact that will leave an extremely unforgettable impression on the audience.
The asymmetry of time and space creates this surreal visual effect, turning into God.
Although this scene is about Neo dodging bullets when facing Agent Smith, during the filming process it was completed by Chu Guang alone, and Xu Jiayan will be created through editing!
Standing in front of the green screen, Chu Guang made an OK gesture, and with the recorder knocking on the board, filming began!
The most impressive thing in "The Matrix" is the time-freezing scene, which is the various slow motions in the movie, such as the heroine Trinity kicking the police in the hotel, and the savior Neo hiding from Smith on the rooftop. The shooting of agent bullets, and the confrontation between Neo and Agent Smith in the subway with two guns flying, etc.
The picture simulated by the computer looked pretty good, but Lin Han felt that it could be more precise, so he pulled a chair and sat next to Tang Rui, and used his fingers to indicate to him on the screen: "This camera's Is the number a little small? Also, in terms of shooting speed, you can test whether it is slightly faster or slightly slower. Let’s test as many as possible to avoid wasting time when shooting.”
