[Two chapters combined into one chapter, 5300 words.

In the basement of the International Hotel, Liu Ruihua and Liu Yifei are sitting in the car, Liu Ruihua is holding a digital camera, ready to shoot some shots, and then make a special short film.

Just now, Liu Yifei was so excited, she just wanted Liu Ruihua to use audio and video editing and processing equipment to create a fake short film.

Inside the car, Liu Yifei, who was sitting in the cab, looked at the car window glass covered by a blue cloth, and she smiled bitterly: "Ruihua, I can't see the outside anymore, how can you let me drive?"

Other beauties knew that what Liu Ruihua and Liu Yifei were going to do needed to be kept secret, so they didn't follow.

Liu Ruihua smiled: "You don't need to really drive, if you want to be real, how big is this basement? It's not enough for a car to go around.

"Huh?" Hearing Liu Ruihua say this, Liu Yifei was a little at a loss.

Liu Ruihua couldn't help but say: "Okay, I'll lift the blue cloth on the right side of the windshield, you start the car now and circle around the basement!"

Liu Yifei breathed a sigh of relief, skillfully started the car, and then looked at the window on the right side that was not covered by the blue cloth with the corner of his eye, and drove the car around the basement a few times.

Liu Ruihua was on the right side of the back seat of the car, shooting Liu Yifei in the left front, so he did not shoot the right front windshield, which will not affect the keying process in the back.

"Okay, almost, let's stop, cover the blue cloth in front of you, and then I'm going to take a shot of the front and right front of the car.Well, although the car is stopped, don't stop with your hands, turn the steering wheel gently...... Okay, that's it, we're done, let's go ahead and deal with it."

After Liu Ruihua finished speaking, he will tear off all the blue cloth in the car, and this fraudulent technique should not be seen by others.

Liu Yifei was surprised: "It's good so soon? Are these shots enough?"

Liu Ruihua said: "Enough, if the length is not enough, you can repeat it. Anyway, the driving action is almost the same.

Liu Yifei said in a low voice: "Thank you Ruihua, this is too important, if this big short film is successful, and the relevant departments show it to some people, we may get a big secret! This contribution to the country will be limitless."

Liu Ruihua smiled bitterly: "I don't care about this, anyway, I'm just helping you, if there is any credit, it's all on you, I don't want it at all."

Liu Yifei blushed and said: "Your credit can only be transferred to your father, my body ......."

Liu Ruihua said with a smile: "Don't talk about this, it's all said that talking about money hurts feelings, and there's no point in talking about this."

went upstairs, Liu Ruihua immediately transmitted the captured picture to the audio and video editing and processing equipment, and then after processing, the blue cloth on the window glass disappeared, and a blank picture appeared.

Liu Yifei said: "Ah, this ...... So if we shoot on a white background, through a transparent car window, wouldn't that be the same effect?"

Liu Ruihua shook his head and said: "Of course it's different, if that's the case, the window glass will be reflective, and it is impossible to carry out high-quality keying, and it must be processed with a blue background to be more realistic."

Liu Yifei said: "So that's the case? What about next? Can the image and voice of the person in the photo be made? This is the key."

Liu Ruihua shook his head and said: "It's too difficult, let's take it step by step. It's a building abroad, right?

Liu Yifei said excitedly: "Yes, it's this building! Can you make the effect that we drive to the foot of this building?"

Liu Ruihua nodded and said: "Yes, this building is too famous, so it is too simple to find the picture material of this building.

"What? Can this be done?" Liu Yifei's eyes widened in surprise.

"Yes, just watch." Next, Liu Ruihua replaced the blank space of the window glass on the picture with a different background: the background in front of the windshield in front of the car was replaced by the main road, and the background outside the glass on the left and right sides of the car became the driving vehicle on the side of the road and the scenery on both sides of the road.

After a while, Liu Ruihua said, "Okay, take a look at the preview screen."

On the screen, the vehicle starts and moves forward slowly, at this time, the scenery of the windshield in front of the car turns out to be a big road abroad? At this moment, the car in which Liu Ruihua and Liu Yifei are riding looks very fast?

Then, the car turned a corner and drove to a building, at which point the camera in the car got out of the car and filmed the entire building...... This qiē is so realistic, as if Liu Ruihua and Liu Yifei really drove a car to a foreign country just now.

Liu Yifei was stunned for a while and said, "Okay, just ...... This is the picture I wanted, it was so real, it was so much better than I imagined! It was amazing! All the pictures that could be seen through the car window were actually added to the background in the post-production? This video can definitely fool anyone!"

Liu Ruihua said with a smile: "The picture of this road and that building just now should be from this era, but I also take it. [,!] No, if you don't look closely, you shouldn't be able to tell that it's been processed."

Liu Yifei immediately said: "Don't worry about this, the person who wants to watch this video is not very familiar with the scenery around this building abroad, he has only been to it a few times, and he has not been to that place for more than a year, even if there are some scenery and buildings on the screen that he has not seen, he will not doubt it."

Liu Ruihua breathed a sigh of relief and said, "Then that's no problem! I dare to say that this effect is already very realistic."

Liu Yifei nodded and said: "Yes, it is very realistic, but how to deal with the characters and dialogues in the car? That is the most important thing!"

Liu Ruihua said: "This is a bit difficult, the photo of the person you gave me and his recording are too blurry.

Next, Liu Ruihua opened the recording of that person, and then performed noise reduction first, removing most of the noise from the tape.

"Well, listen." Liu Ruihua turned his head to Liu Yifei and said.

Liu Yifei said a little excitedly: "Okay, now the voice is much clearer, but it's still a little unspeakable, it's not like we are talking in the car, right?"

Liu Ruihua said: "Well, the frequency, level, and dynamic range still need to be processed.

After Liu Ruihua finished speaking, the low frequency and high frequency of this recording were attenuated, and the middle frequency was increased.

Feeling that the level was about the same, and the noise was acceptable, Liu Ruihua used a digital equalizer to process the mid-frequency part, mainly to improve the intelligibility and clarity of the entire speech.

Feeling that it was okay, Liu Rui Huaran said to Liu Yifei: "Listen again, I haven't heard this person's voice, so I don't know if it's like it.You should have heard this person's real voice, right?"

Liu Yifei nodded and said: "Of course I have heard it.Ah, now this voice is much more real, not so far away.Hmm, but this voice seems to be a little too clear? That person has a strict rhinitis, and his voice is more ......."

Liu Ruihua waved his hand and interrupted: "Understood, rhinitis is right? I'm here at 500 and 800hz to raise a little.

Liu Yifei listened for a while, and patted Liu Ruihua on the shoulder excitedly and said, "Okay! This is definitely what it feels like that person is talking within one meter of us, but how does it feel as if he is talking face-to-face in a room? Not like he is in a car?"

Liu Ruihua gave Liu Yifei a thumbs up: "Admire, you ears, I'm really convinced! Yes, this person's recording is in the room, and the sound field in the room is of course different from the sound field in the car...... Well, please listen again, this time it's guaranteed to surprise you."

After hearing this, Liu Yifei said excitedly: "Oh my God, this is perfect! This kind of voice is definitely the feeling of two people talking face to face in a car! However, the content we need is not the content of this recording. How can we use this voice to create the recording content we want?"

Liu Ruihua smiled bitterly: "Digital audio processing can simulate this sound, but it's not real. The picture can be faked, the sound is too difficult. You write what you want, this recording is relatively long, I try to find out what you want in this recording, and then synthesize."

"It's amazing! Well, let's make it simple: 'When will you do what you promised me?' Just this sentence, see if you can deal with it?"

Liu Ruihua sighed and said, "I'll try it."

Next, Liu Ruihua put on headphones, listened to this recording constantly, and copied the recording waveform when he encountered useful materials.

The process was relatively long, and Liu Yifei waited patiently on the side.

"Well, based on your content and the material from this recording, I can only edit this sentence: 'I've got your business done, and you're going to implement my business, right?' Listen to it."

Liu Yifei listened to it for a while, her face swelled and reddened, and said: "Okay! This content is similar to the meaning of what I said! However, it sounds a bit like a word by word popping up, very stiff, is there a way to improve it?"

Liu Ruihua smiled: "Of course there is, I will let you determine the content of the recording first, and then deal with it."

Next, Ruihua faded in and out of each word, and then added the sound of breathing and saliva.

Liu Yifei listened to it a few times, and the more she listened, the more excited she became, and then she suddenly hugged Liu Ruihua and said: "Ruihua, thank you! This voice is so real and perfect, it is simply done in one go, and no one will ever think that this is a piece of paper piece by word!"

Liu Ruihua smiled: "Wait, don't be so excited, this is not the most perfect! Wait a minute, we have to add the sound of the car engine, the horn outside the window, the sound of overtaking, etc., and the sound of people outside the window, etc., and then combine the picture - I dare to swear, except for you and me, no one in this world will doubt the authenticity of this picture and sound!"

Haha, now that you have taken the initiative to give up this result, then I'll wait for all the processing to be completed, don't you have to make a promise?"

Liu Yifei gritted his teeth and said: "If you promise yourself, you will promise yourself! Who is afraid of whom? [,!], I'll thank you when you're done!"

"Thank me?" Liu Ruihua immediately boiled and continued to work.

Next, Liu Ruihua scanned the person's photo, then made a 3D model, and then used digital scenery painting technology to paint.

"The nose is a little higher here, this person is a half-blood......"

"The color of the hair is not all black, with a little yellow ......"

"The black mole on the forehead doesn't seem to be so obvious, and it fades a little more......"

"The cheekbones seem to be a little more prominent? This person has a square face......

Next, according to Liu Yifei's guidance, Liu Ruihua constantly modified the face picture made by the computer.

"Okay, let's go back to the previous picture...... That's right, that's it! It's too similar, but it's a pity that this model is not a real person, so how to deal with it next to confuse the real with the fake?"

Liu Ruihua smiled: "Don't worry about the skin and realism, the most important thing is the 3D model, I'll deal with it...... How about a look?"

Liu Yifei looked at the vivid face on the screen, slapped the table and said, "Okay, it's too similar......! It's like a real person, I didn't expect a computer to do this?"

"What's so surprising about that? Even the most complex hair and hairy animal computers can make it, and it's not too difficult for digital technology to make a human face.

Liu Ruihua said this, but to be an animal with hair all over the body, this is too difficult.In the future, there will be a teenager's drifting,All the pictures in it are shot on a blue or green background,The big boats and waves at sea, tigers, orangutans, monkeys and other animals are all made by computer.It's just that one tiger,I used digital scenery technology to draw a year.,The final picture is absolutely fake,It's more real than the real thing!

Before Liu Ruihua crossed, he was a famous master of audio and video and computer technology in China, and there was no great difficulty in drawing faces.

Liu Yifei looked at it carefully, and said: "He is not a pure yellow person, the skin on his face is not so yellow, he should be white......"

Liu Ruihua quickly adjusted, and then said, "Is this Yan?

Liu Yifei looked at the enlarged picture and said, "This person's skin doesn't seem to be so delicate......"

Liu Ruihua smiled bitterly: "This guy is really a freak, I thought the skin on his white-skinned face should be delicate......? This is going down, isn't it?"

Liu Yifei looked at it many times, and then said excitedly: "It looks very, very similar. So what now? How do you put him in our car? Is it the kind of 'head changing' technology?"

Liu Ruihua smiled: "Yes, it's like transferring the head of Cai Zhuoyan's swimsuit to the body of her military uniform. Didn't I just let you put on that person's clothes and then turn around and take a few pictures? I'll deal with it now."

Liu Yifei was a little worried: "But my figure is different from that person's figure, and my hands are different, will there be any mistakes?"

Liu Ruihua explained: "You don't need to worry about this, your hands will not appear in the picture at all, and your body will only appear a little, and most of the pictures are the head of that person...... Well, that's the effect, you see."

Liu Yifei saw that the picture of himself turning back had become the picture of the person looking back, and it was so real and seamless, so he trembled a little and said: "Yes, yes, this is the picture I want!

"Okay, I'll be fine soon. I'll mix in the audio again...... Okay, you look at the picture and listen to the sound, how does it feel? What else needs to be adjusted?"

Liu Yifei watched and listened repeatedly, and finally she desperately suppressed her excitement, calmed down and observed carefully, and said: "It's all perfect! If you have to pick a bone in the egg, I think the picture after that person turns back is too clear, although it is real, but it is too real, but I feel a little ......."

"So, I'll add a backlight effect." Next, Liu Ruihua made a beam of sunlight into the car, and with this backlight, the person's face became a little darker......

"Okay, don't adjust it, that's it! With this shadow effect, the picture is more realistic, hurry up and output it all!"

Liu Ruihua let out a sigh of relief and said, "It's finally okay? It's been a few hours of tossing.

On the screen, the car starts, crosses the road in a foreign country, and stops at the edge of a very famous building.

At this time, the driver turned around and asked, "I've taken care of your business, and you're going to implement my business, right?"

At this time, the person filming behind the car said in English: "You can rest assured that we will work for the intelligence department, and we will talk about the specific things in my upstairs office!"

Then the car turned on, the photographer patted the building, then turned back and patted the person in the car, and the scene stopped.

"Ruihua, you are really amazing, too great! This can absolutely be fake! I dare say, you have done a great job this time! By the way, can the highest technology in the United States make such a picture?" After being excited for a while, Liu Yifei was a little worried.

Liu Ruihua said confidently: "I am absolutely the only one in the world who can make such an effect! Their technology can make similar things, but it will definitely not be so realistic!"

Liu Yifei waved his fist and said, "That's great.Ruihua, really.[,!] Thank you! But how do you want me to thank you?"

Liu Ruihua looked at Liu Yifei, who was suddenly blushing and shy, swallowed a mouthful of saliva and said: "This problem is a bit complicated.

ps:The last few chapters are all technology,However,It's all real technology.,Not a false technology of "special function".If you can understand it,Then you're very good!Can't understand it?Great,I can finally fool people!However,I won't keep writing about technology,Entertainment,Stars,Beauty,There will be ah! These days, it's cold.,Rhinitis is terrible.,Hundreds of sneezes a day.,Dizziness and writing technology.,It's really dizzy! Thank you again for your support!
