Bright Era of China Entertainment

Chapter 338 Explanation and conclusion

As we all know, apart from space opera sci-fi films such as "Star Wars", some sci-fi films involving future technology basically have scenes of weightlessness.

The "Hope" micro-movie belongs to the latter, and even has a bit of a hard science fiction tendency, and the presentation of the weightlessness scene is naturally indispensable.

When Chu Xuan and Liu Yifei were imagining the story of "Hope", when discussing the plot with Liu Yi later, they thought that they hoped to present all kinds of plots that could embody 'sci-fi' elements as much as possible, with this idea in mind Come discuss with Liu Yi.

Regardless of whether it's money or responsibilities, Liu Yi is worthy of the title of a gold medal screenwriter, combining some scientific materials to write out these "science fiction" plots one by one.

However, the writing is written, but how to capture these pictures with the lens is another problem for Wen Muye and others who have no experience.

"The spaceship fell, and I can imagine that the interior of the spaceship must have been shaken, and some objects were also scattered around by the shock, thus floating in a weightless environment." Kong Sheng said.

Chu Xuan, Liu Yifei and the teachers nodded. The spaceship fell from the starry sky of the universe, and the interior was shaken. Some books, screws, and some small objects floated in the air out of their original positions. Such a picture is not difficult to imagine.

Moreover, such a picture is logical.

It would be strange if the spaceship crashed without any change in the interior of the spaceship.

"But I have a question. Hasn't the spacecraft already crashed on the planet? This planet still has oxygen, so why is there a weightless environment?" Kong Sheng asked.

Li Xue and the teachers raised their eyebrows and looked at Liu Yi.

Liu Yi is the chief screenwriter, so he naturally needs to answer this question.

Hearing Kong Sheng's question, Liu Yi lowered his head and flipped through the script, then pointed to the character's lines on a page and said, "I explained the setting in this aspect in the form of lines. Teacher Kong probably didn't read the details."

"Before writing this plot, I searched for relevant scientific information, and also asked my friend Liu Cixing, a writer who has done research in this area, and got some answers."

"First, the spaceship crashed, but the exterior of the spaceship was intact. This is the basic setting."

The crowd nodded.

"Since the exterior of the spacecraft is intact, if the oxygen system is damaged and the oxygen is exhausted, there will be no oxygen in the cabin."

The crowd continued to listen.

"An environment without such a substance as oxygen just means that the space pressure is extremely small, but it does not mean weightlessness."

"In other words, weightlessness has nothing to do with gas, it has nothing to do with gravity."

"As for the planet where the spacecraft fell, the gravitational force of the earth's center is several tenths of that of the earth, so when we humans walk on this planet, it is like walking on the moon. We are floating and weightless while walking."

"This is why there is a weightless environment after the spaceship crashes on a planet with air and gravity, in a closed cabin, after both the oxygen system and the gravity system are damaged."

Kong Sheng and Li Xue thought about it for a moment, and then gradually became enlightened.

"I don't understand these professional knowledge, but I understand Mr. Liu's explanation." Kong Sheng smiled slightly, and after thinking for a moment, he said: "That is to say, in the script, in the entire spaceship, only Chu Feng and Liu The cabin on the floor where Akane is located, the gravity system and the oxygen system are good."

"Yes." Liu Yi nodded and said, "In order to cultivate two clones, Chu Feng and Liu Qian, the scientists separated the system circuits of the spaceship, so when the spaceship fell, Chu Feng and Liu Qian It is logical and self-consistent that the system in the cabin where Akane is located has not been damaged."

"However, in the absence of oxygen, Chu Feng and Liu Qian found the hatch on the ground that was blocked by debris in order to escape."

"The hatch is opened, and one side is the air with oxygen substances, and the other is the environment without oxygen inside the hatch."

"The pressure of the environment without oxygen becomes smaller, and the pressure of the environment with oxygen substances is higher, and the collision between the two will form a strong impact."

"That is to say, the air at the side where Chu Feng and Liu Qian are, will suddenly produce a strong thrust on them, pushing them into the cabin behind the cabin door instantly, so this shot needs to be shot with a sense of horror. .”

"Because of the violent air fluctuations, the system of the cabin where Chu Feng and Liu Qian are located sensed it, and then activated the protection mechanism, and the gravity system and oxygen system were automatically shut down."

"At the same time as the gravity system was automatically turned off, due to the gravity of the planet, all the objects in the cabin where Chu Feng and Liu Qian were located began to slowly float. This is also a shocking scene."

"And this plot will push the plot to a climax. Whether Chu Feng and Liu Qian can escape under the condition of a sharp drop in oxygen will make the audience feel more nervous and excited."

Wen Muye smiled at Liu Yi: "Ms. Liu's plot design is really good, full of drama, but combined with scientific knowledge, it's a bit hard science fiction."

Wang Bowen continued: "Chu Feng and Liu Qian opened a hatch, and the oxygen decreased, and opened a hatch, and the oxygen decreased again. I like this escape story, it's exciting to think about."

Chu Xuan and Concubine Liu Yi nodded slightly, they also liked the plot designed by Liu Yi.

Oxygen originally permeated only one cabin layer. As they searched for a way out and opened one closed cabin door after another, the oxygen would collide with the vacuum in one vacuum cabin after another, and it would spread rapidly, which also represented The density of oxygen will drop.

In other words, the oxygen will become thinner as the hero and heroine escape.

If this plot is performed well, it can cause a lot of tension to the audience.

Li Xue said slowly: "No wonder Chu Xuan and Qianqian don't need to wear space suits in this plot. It turns out that the air with oxygen was poured into the cabin, causing the cabin to have oxygen, but the gravity system was turned off, and Chu Xuan and Qianqian had to perform weightlessness again." feel."

Kong Sheng also understood now, but said: "To simulate weightlessness, we can use the method of hanging steel wires. Chu Xuan and Qianqian cooperate with Teacher Wia, and they can perform this weightlessness."

Wang Bowen nodded, raised his legs and said, "Many sci-fi films in Hollywood also use steel wires to create a feeling of weightlessness. As long as the actors and Mr. Wia cooperate well, it's not difficult."

Wen Muye turned his head and reached for the mineral water in front of the monitor, twisted the cover and said, "Senior brother and sister have a very good body and can mobilize their bodies very well. I believe weightlessness is not difficult to shoot."

Concubine Liu Yi quietly stretched out her right index finger and poked Chu Xuan's waist. When Chu Xuan turned her head to look at her, she muttered, "Diao Weiya is too tired to control her body."

Chu Xuan couldn't help laughing. Concubine Liu Yi had a deep understanding of this aspect of Wia drama when she was filming "The Condor", so he took Concubine Liu's hand and kneaded it a few times to encourage her.

"But how do you shoot a weightless object?" Wen Muye took a sip of water.

As soon as the words were finished, Liu Xiaoli's cell phone rang, and the ringtone interrupted everyone's thoughts.

Liu Xiaoli gave everyone a sorry look in a daze, opened her bag to take her mobile phone, and got up to answer the call.

After answering for a moment, she turned to Chu Xuan and said, "Director Chen and the others are here."

Chu Xuan's eyes lit up, he stood up and said with a smile, "Here comes the solution to the problem."

He followed Liu Xiaoli's pace of walking out.

Wen Muye and Kong Sheng were a little dazed, not knowing who Director Chen and the others were referring to.

"Director Chen Kaige, Director Tang Jili, and Director Zhang Jizhong are here." Liu Yifei said, getting up to follow Chu Xuan.

The teachers were stunned for a moment, and quickly realized.

The director Chen that Liu Xiaoli was talking about was able to come to the studio again, and there was no one else except Chen Kaige, the shareholder of Brilliant Times.

Although I don't know why Chen Kaige and other great directors came here, but out of respect for their predecessors, Wen Muye and the teachers stood up one after another, walked out of the studio, ready to welcome them.

Walking halfway, I saw Chen Kaige, Tang Jili and Zhang Jizhong walking over with their assistants.

"You guys are really hot, there are a lot of reporters and paparazzi at the door." Chen Kaige teased Chu Xuan and Liu Yifei.

Having been in the entertainment industry for many years, Chen Kaige and the others saw that there were many reporters and paparazzi at the door, and they knew that these people came for Chu Xuan and Concubine Liu Yi.

Chu Xuan and Concubine Liu Yi smiled, and greeted each other warmly without answering the topic.

"Teacher Kaige, Teacher Tang, Brother Zhang." They said separately.

Wen Muye and Kong Sheng also greeted each other.

"Hi everyone." Chen Kaige and the others replied to each other.

A group of people walked and chatted, leading Chen Kaige and the others to the studio.

After arriving at the studio, Wen Muye and the others were introducing, and Chen Kaige and the others were visiting.

"This scene is well built." Tang Jili said.

"Thanks to Mr. Wang Bowen's precise composition." Wen Muye said.

Chen Kaige and the others glanced at Wang Bowen, and he said with a forehead: "Mr. Wang has worked in Hollywood for several years in special effects work. This scene and the layout of the green cloth can be seen as an experienced professional."

"I've always been on the way of learning." Wang Bowen said modestly.

After looking around, he led Chen Kaige and the others towards the monitor.

"Teacher Kaige, Teacher Tang, Brother Zhang, you all came at the right time, just in time for us to encounter a problem." Chu Xuan walked into the studio.

"That's a coincidence, let's hear it, what's the problem?" Chen Kaige said kindly.

The field manager moved three chairs, and the group sat down separately.

Under Zhang Jizhong's suggestion, Liu Yi distributed three scripts, indicated the page numbers, and told the three directors the shots that were difficult to shoot.

Chen Kaige and the others read the script while listening to Wen Muye explaining the difficulties of filming.

"Has the script been changed?" Chen Kaige said, they had read the original script of "Hope" and found a difference.

"Yes, Qianqian proposed a concept of space, and the door is set on the ground." Liu Yi nodded.

"Good modification! I like this shot, it's very imaginative in space." Chen Kaige praised, Tang Jili and Zhang Jizhong glanced at Concubine Liu Yi, nodded their heads appreciatively.

The corners of Concubine Liu Yi's mouth turned up, she was a little happy because the scene changed by her proposal was praised by the big director.

After reading the script for ten minutes and listening to Wen Muye's narration, Chen Kaige lowered his head slightly, his gaze still staying on the script, and said, "According to what you said, there are two difficulties. One is that when the gravity system is turned off, Chu Feng and How to take pictures when the objects in the cabin where Liu Qian is slowly starting to float; one is how to take pictures when there are floating objects in every cabin.”

Wen Muye nodded, and Chu Xuan and Concubine Liu Yi made a listening statement to the teachers.

"Can't use special effects?" Tang Jili asked.

Wang Bowen shook his head and replied: "It can be produced with special effects, but there are too many elements and the time cost is too high. President Chu and Producer Liu hand in the homework at the end of June, so there is not enough time for this production."

Tang Jili nodded slightly, expressing his understanding.

Chen Kaige held the script in both hands, looked up at Wen Muye, and said, "A Space Odyssey directed by Stanley Kubrick was released in 1968, did you know?"

"I know." Chu Xuan, Liu Yifei and Wen Muye said in unison.

"I watched it at Beiying, as a teaching film for developing camera thinking." Wen Muye said.

"We saw it in the freshman acting class, and it was a simulated performance." Liu Yifei said.

Chen Kaige nodded and said: "Constrained by the conditions of the industrial foundation at that time, the weightlessness was completely simulated by people walking around, without the cooperation of Wia. If you only look at people, it seems that the sense of weightlessness is not strong."

Chu Xuan, Liu Yifei, and Wen Muye thought about it. There was a scene in this movie. There was a woman walking around in the cabin. Although she walked very slowly and seemed weightless, it was obvious that the traces of this woman’s acting were heavy. , resulting in some distortion of the picture.

Chen Kaige said again: "But there is a pen floating in the air and slowly rotating. This movie uses this shot to change the trajectory of the object to set off the weightless atmosphere, which made the movie fans at that time exclaim amazing."

Chu Xuan, Liu Yifei and Wen Muye thought about it and nodded.

Although it doesn't look amazing now, this lens can be said to have created a new path of science fiction in 1968.

"How did this shot come about?" Chen Kaige held the script in one hand and gestured with the other: "They used a thin piece of transparent glass, then fixed the pen on the glass, and finally turned the glass artificially to drive the pen to rotate, With the camera shutter and focal length adjusted, the pen is in slow motion, achieving the effect of floating in a weightless environment with object movement tracks.”

Chu Xuan and Concubine Liu Yi came to a sudden, Wen Muye and the teachers were thoughtful.

"I understand what Director Chen means." Kong Sheng said: "However, in the scene of "A Space Odyssey", only one pen is weightless, but in our script, many objects are weightless."

"Facing an object stuck to the glass, we can make the reflection of the glass disappear by adjusting the camera parameters."

"But facing many objects stuck to the glass, and there is a panoramic view in the script, the lens of the camera penetrates through layers of glass under the illumination of the light. I find it difficult to deal with the layers of reflections. If it is not handled properly, the glass will be photographed by the camera and go through.”

Everyone frowned. The question Kong Sheng raised was really difficult to solve, so they couldn't help but think about it.

Chen Kaige smiled, and seemed to have a solution, but he just didn't say anything, as if he was watching a play.

After a while, Liu Yi suggested: "We can cut the glass. There is no need to use a complete piece of glass. We can even cut the size of the glass into an area smaller than the size of the object, so that the object can completely block the glass."

"Just cut the glass into a regular shape, such as a square or a rhombus, and we thread two steel wires on the opposite corners of the glass."

"Finally, let the staff go to the roof of the scene, and carry two steel wires to make regular movements, so as to drive the movement of the object and make the object have a trajectory."

Concubine Liu Yi spread her hands and smiled: "Isn't that enough?"

Chen Kaige stretched out his hands and clapped slowly, saying, "Mr. Liu is smart."

Wen Muye suddenly lifted his thinking head, and said, "Brother Liu is amazing! This method is good!"

"This is fine." Kong Sheng nodded.

"You can try it." The corner of Li Xue's mouth raised slightly.

"But..." Concubine Liu Yi had some doubts: "But the objects in the script also include small objects such as pens and screws. How can the size of glass be smaller than these objects?"

Hearing this, Wen Muye pointed to the script and said, "Most of the objects in the script are relatively large, such as a newspaper, a teacup, a piece of clothing, etc. These objects can be moved by glass that is smaller than them. .After solving these objects, the remaining small objects are glued with glass larger than them, but we can stagger these objects."

"Mr. Kong was just worried about the overlap of the front and back of the glass, which made the camera unable to handle the multiple reflections. But now that most of the objects are resolved, the remaining small objects can be arranged in a random arrangement."

"In this way, the camera always only needs to deal with one reflection of glass. If there is only one reflection, it is very simple to make this reflection disappear by adjusting the parameters of the camera."

"When the reflected light disappears, the glass loses the light source in the lens, and the object that loses the light source becomes dark in the imaging of the camera."

Concubine Liu Yi understood for a few seconds, nodded repeatedly and said, "Understood."

"One more question." She raised a hand.

All the teachers looked at her with amused look when she raised her hand like a student.

"Since steel wires can be used to move objects, why do we have to use glass? Isn't it good to directly thread steel wires into objects?" Concubine Liu Yi asked curiously, her face full of desire to acquire knowledge points.

Liu Yi shook his head, and explained patiently: "From the perspective of physics, when an object keeps moving in a weightless environment, as long as the weightless environment does not disappear, the object will behave in a regular and eternal manner under the pull of constant gravity. In movement, there is only a difference between fast and slow, but movement must be constant and regular.”

"Most of the objects in the script are irregular. Irregular objects are moved by the staff with steel wires. It is difficult to make the objects move with a constant trajectory by manpower, especially on the big screen. In the process of rendering, it will show a picture of various objects moving in a mess, which is not in line with science."

"The cut glass is a regular object, just like the square and the rhombus with the same side length I just mentioned. As long as manpower drives these regular objects to move, it is relatively easy. Just make this piece of glass, for example, make a regular shape. With the rotating action, the objects on the glass will also rotate regularly.”

"As long as it rotates a circle regularly, the image of the object rotating can be kept on a constant and regular trajectory in the post-processing."

Concubine Liu Yi bowed her head and quickly took notes in her notebook. Although she still couldn't understand, she was greatly shocked.

Tang Ji said to Liu Yi: "Ms. Liu is professional."

Chen Kaige also said: "It stands to reason that the professional knowledge of screenwriters is actually much more than that of directors and producers, but there are not many such screenwriters in China, and Mr. Liu is one."

"He knows a lot, including astronomy and geography." Zhang Jizhong, who has worked with Liu Yi for many years, praised him.

"Hey! Brother Zhang, don't come here, you're going to kill him, right?" Liu Yi couldn't laugh or cry.

Wen Muye grabbed Liu Yi's shoulder and said, "Brother Liu, don't be modest, you are really awesome."

"That's enough, that's enough." Liu Yi couldn't bear the "praise and kill", and hurriedly said: "I found a way, let's do it quickly."

"I'll do it." Teacher Yang, the leader of the props group, stood up.

"I know this kind of transparent glass, I have used it several times before." He said.

"The glass cutting master should be invited to the studio, otherwise he won't know what to cut into." Chen Kaige reminded.

Teacher Yang shook his head: "Director Chen, how do you cut the glass? Everything will be broken. Please come over and have a look at the size of the props, and then customize according to the requirements of the teachers."

Zhang Jizhong laughed loudly, and said, "That's right, how do you cut the glass special girl? You chatted for a long time and didn't find this flaw in logic. It's quite funny."

Chu Xuan and Concubine Liu Yi were taken aback by the teachers, but immediately became happy.

Xu Shi was so focused on the chat that he forgot this bit of common sense.

"Mr. Chu, if you ask the master to come over and order..." Teacher Yang said.

Chu Xuan raised his head and replied to Teacher Yang: "Money is not a problem, I want efficiency."

"That's easy." Teacher Yang smiled slightly, and went out with an apprentice from the props team.

Wen Muye took a look at Teacher Yang, then looked at Chu Xuan and Concubine Liu Yi, and said, "Brother and sister, the subsequent escape scene will be postponed."

He paused, glanced at Chen Kaige and the others, and said, "It just so happens that the three directors are here, so let's shoot the most difficult scene, that is, the 3D space where you found the hatch?"

Hearing this, Chu Xuan and Concubine Liu Yi looked at Chen Kaige and the others.

"What are you looking at us for?" Zhang Jizhong squinted his eyes.

"Under the guidance of the teachers." Concubine Liu Yi said charmingly.

Chen Kaige flipped through the script, and the more he read it, the more interested he became, and said, "Go get ready, I've never seen such a scene before, it's interesting."

Seeing that Chen Kaige and the others were willing to guide, the excitement in Wen Muye's eyes flashed, he stood up and said to Kong Sheng, "Teachers, prepare the lighting and camera."

"Brother and sister." He said to Chu Xuan and Concubine Liu Yi again: "Make up and change clothes?"

"Okay." Chu Xuan and Concubine Liu Yi got up and walked towards the dressing room.
