Chapter 595: Bullet Time (Ask for Subscription)

The stronger the enemy, the more motivated Lin Han will be, no matter how he wins or loses, he can shoot this movie to the extreme, and leave the rest to the audience. Pen × fun × Pavilion www. biquge。 info

Today's audiences are not the same as in the past, they know how to distinguish the quality of the movie, they will not blindly follow the trend, and their tastes are becoming more and more picky, so what Lin Han has to do is to put his conscience in front of the audience!

The most impressive thing in "The Matrix" is the scene where time freezes, that is, various slow motion in the movie, such as the heroine Trinity provokes and kicks the police in the hotel, the savior Neo dodges the bullets of Agent Smith on the roof of the building, and Neo and Agent Smith fly up with two guns in the subway and so on.

These shots all magnify the action time of a moment, such a picture is presented in front of the audience, and Lin Han can drive the audience to appreciate this moment from all angles!

This unrealistic view of time can actually be more integrated into the background of the film's story, forming a unique visual impact, which will leave an extremely unforgettable impression on the audience.

Of course, the most classic shot in this movie is the magical "bullet time", which is famous throughout film history.

In terms of visual effects, this is actually a kind of slow motion in disguise, which uses the normal camera speed to show high-speed actions such as bullet flight and fighting, so it looks like these actions are slowing down, but ordinary people not only don't feel the drag, but the pleasure of speed is infinitely expanded!

When Lin Han first watched this movie, he was shocked by the amazing creativity of the Wachowski brothers, Neo slowly leaned over to dodge the bullet in the rotating camera movement, people really saw the movement of the bullet for the first time, and saw the panoramic scene of 360° rotation of the bullet when it was stagnant.

Right now, the scene they are about to shoot is the famous bullet time, but except for Lin Han, the rest of them don't know what this shooting method will bring to the world.

In front of the green screen, Chu Guang, who was wearing a black windbreaker, had an extremely thin steel wire hanging from his waist, without the help of this Weiya, he would not have been able to make those difficult movements, this is the legendary "Iron Plate Bridge" posture!

Judging from the picture in the movie, Neo's whole person seems to have broken through the limits of gravity, and his whole body is parallel to the ground.

Lin Han knew that there were about five ways to shoot bullet time, but he hadn't tried it specifically, after all, he was just an ordinary reader in his previous life.

What is Bullet Time?

Many viewers think that bullet time is all about shooting bullets smashing things or slow motion, and this view is wrong!

Only in the extreme time change or no change of space displacement is bullet time!

The asymmetry of time and space creates this surreal visual effect, which becomes a god.

To put it simply, time is limited, but the concept of space is free. It is very expensive to shoot this kind of footage, either with a super-high-speed camera with a robotic arm or with a camera array.

……

"Director Lin, I really can't shoot the effect you said. Photography director Zhao Yuankun said with some surprise, he tried several times, but it didn't work at all!

Lin Han touched his chin, and he asked, "How did you do it?"

Zhao Yuankun pointed to the shooting site not far away, "I strapped a small transmitter to the camera so that the camera can move at a very fast speed. ”

"Actually, I have a better idea, do you think it's feasible to have a circle of cameras on the green screen side and have the cameras capture each shot quickly and continuously, and then post-process those shots?"

Lin Han is only talking on paper now, this method is what he saw in his previous life, how to use it, how many cameras to put up, how to make these cameras start shooting quickly, he doesn't know, so he has to consult Zhao Yuankun, a professional.

The role of the director of photography is like this, to provide the director with professional knowledge in photography, Lin Han does not expect to be an all-round person!

Zhao Yuankun patted his head with his hand, and he said to himself: "It is theoretically feasible." It is possible to use many cameras to release the shutter at the same time as the actor's performance, capture the image of the moment, and then show it continuously. But we don't know how many cameras we need, how many shots we need to take, and what angles and directions to shoot from, and we can't solve these problems!"

Isn't that easy?

Lin Han snapped his fingers, "Now that computer technology is so developed, let's just find someone to make a computer model for analysis, everything is possible in the computer era!"

The entire crew was active for Lin Han's idea, and the actors were happy and relaxed one by one, at least they didn't have to work too hard, but Chu Guang couldn't.

Lin Han used a video camera to film Chu Guang's performance in front of the green screen, and then transmitted the image to the computer, and analyzed Chu Guang's movements through software to make his actor model!

This is a specially hired foreign aid from the crew, Tang Rui, an expert invited from the Computer Research Center of Tsinghua University, in the three-dimensional software, a number of cameras are placed in the three-dimensional space according to the set trajectory, and then a virtual picture is generated from the position of each camera, and after they are continuously screened, the effect of booking the camera is obtained.

"Mr. Lin, what do you think of this?"

The picture simulated by the computer looks pretty good, but Lin Han thinks it can be more detailed, so he dragged a chair and sat next to Tang Rui, and compared it to him with his finger on the screen: "Will the number of cameras be a little small?" Also, you can test the shooting speed to be a little faster or a little slower." We tested as much as we could so that we didn't waste time shooting. ”

That's the good thing about the age of technology, if you don't have a computer, how much film will you waste if you just start shooting?

Now you can simulate the best solution directly on the computer, saving time and money!

Tang Rui didn't have any impatience, he slowly and carefully debugged according to Lin Han's requirements, and the whole day passed before the shooting plan was determined.

……

Early the next morning, Lin Han came to the studio, he was even shooting this shot in his dream last night, and now he can't wait to shoot it on the scene.

Although this scene is the scene where Neo faces Agent Smith to dodge bullets, it was completed by Chu Guang alone during the filming process, and Xu Jiayan was made through editing when the time came!

In front of the green screen, Chu Guang, who was hanging under coercion, was a little nervous, because there were too many cameras around him, even celebrities had never seen so many.

Hundreds of cameras are precisely placed on a route set by a computerized tracking system, and the shutter control is centralized, making it easy to select and adjust the shooting moment.

Xu Jiayan, who had no role in the scene for the time being, looked at this posture dumbfounded, he turned his head and asked Lin Han: "Director, how many cameras are there here, it's too scary!"

"122 units. Lin Han, who was looking at the monitor screen, replied without raising his head, this is the result of the crew being busy for two hours early in the morning!

Xu Jiayan breathed a long sigh of relief, "With so many cameras, the cost must be very high, right?"

Lin Han smiled bitterly, he said with emotion: "This is not taking pictures, this is burning money!"

"You deducted our salary just to play this, I've been filming for so many years, and I haven't seen a crew shoot in this mode, what if you suddenly want to experience it?"

"Don't even think about it, I was cheeky enough to rent these cameras, and they will be 100,000 lost after one click. But the effect is really good, very good-looking, and it can stop time completely! This is incomparable to other shooting methods. ”

At the shooting site, these Nikon cameras were neatly arranged, and each camera had wires of different colors extending out, which the layman couldn't read at all.

After the preparations were ready, Lin Han took the megaphone and shouted: "Attention departments, the shooting will start immediately, please stand back a little if you have nothing to do with it!" Chu Guang, are you ready?"

Chu Guang, who was standing in front of the green screen, made an OK gesture, and with the knocking of the scene notes, the shooting began!

The large electric fan in front of Chu Guang began to whirre, and the feeling of a windbreaker fluttering in the studio could only be an artificial wind source, and with the wind rising, Chu Guang slowly leaned back with the help of coercion, and the bullet began!

The camera shutters that surrounded Chu Guang began to ring one after another, and they began to take pictures according to the computer's pre-programmed program and time intervals.

From the starting position, this high-speed camera accurately grasps the attitude of bullets flying in the air, and the high-speed camera with a maximum of 12,000 frames per second is very powerful!

The 122 Nikon cameras took pictures at an average speed of 300 frames per second, and each frame of the image was scanned into the computer for processing.

In these few seconds, a lot of film was consumed, and Lin Han felt distressed by burning money.

The most important thing is that he is not sure that this shot will be in place, so he has to wait for the computer to process the results before preparing for the reshoot.

Tang Rui was already busy at this time, he used the image pattern to recognize the photos he had just taken, virtually repaired the differences between the two adjacent photos, and generated a coherent and smooth movement of the subject under the 360-degree lens after rendering!

Then use a computer software that Lin Han doesn't understand at all to carry out the final synthesis and correction, and fuse the coherent moving image with the background, all the employees were speechless for a long time in surprise after seeing this semi-finished product!

It's amazing!

It's an epoch-making idea!

It's not slow motion, it's better than slow motion!

Originally, many employees were curious about how to shoot Neo dodging bullets, but after seeing Lin Han's creative shooting method, they were all stunned!

"What's the name of this shooting method?" Xu Jiayan said in a daze, he only hated that he was not Chu Guang, and he couldn't enjoy such treatment.

Lin Han's whole heart relaxed, and he replied: "It's called bullet time, and you will often see it in movies, TV series, and even advertisements in the future!"
