Chapter 101: The first trailer of Xumi City
The projector is so big now, and it is hand-cranked. Do I have to crank it all night? It seems that I need to discuss with Senior Kawi how to take turns. If each game is ten minutes... change players every three games?
If we start at 7pm, theoretically we can broadcast 30 shows a night... In reality, the number of viewers will decrease after 11pm, so there is no need to broadcast until 12pm...
Harold thought about it.
Kavi quickly checked the relevant equipment, installed the film, and then expertly adjusted the position of the projector, the focal length of the lens, the size of the projection, turned off the lights, turned on the elemental force lamp, and adjusted the light intensity.
Then he turned the projector handle and lowered the phonograph needle in the dark. The image was projected onto a white screen supported by two tall poles in the studio, while Carvey's voice came out of the phonograph speaker.
At first, due to the slight time difference between the projector and the phonograph, there was a mismatch between Carvey's lip movements on the screen and the sound on the phonograph. But Carvey quickly slowed down the speed of the crank and slightly reduced the playback speed, trying to synchronize the two.
Harold watched quietly, comparing in his mind the differences between these familiar devices on the continent of Teyvat and the devices on Blue Star.
Well... the projector can play movies at fast and slow speeds, and can also play color movies. These things were not available on Blue Star until the 20th century. Unfortunately, dubbing can only be done with a phonograph.
Because there is no microphone, the sound quality of the phonograph recording is poor, but it is better than the phonographs on Blue Star of the same period. The phonographs on Blue Star in the 19th century... Not to mention the complex structure of the human voice, even the sound of musical instruments will be recorded in full loss quality.
The length of recording time is consistent with that of Blue Star's early phonographs, both are short, with five minutes being the limit.
After all, without electromagnetic induction, there would naturally be no steel wire recorder. Otherwise, by relying on the conversion of magnetic changes and current changes, and the conversion of current changes and sound wave changes, long steel wires could be used to achieve long-term recording. The length of the steel wire would determine how long the recording time could be.
While Haroldt racked his brains to recall some knowledge he had learned in his previous life, he watched the "little movie" made by Kavi. As the old saying goes, he knew the principle roughly, but he couldn't do it if he was asked to do it.
Moreover, this is the continent of Teyvat, and the effects of using electricity and using electricity with elemental power will definitely be different.
So, Senior Elhaisen, when will you become the chief clerk? Your lovely junior wants all the information about the "Nikola Coil".
The nearly ten-minute video soon came to an end, and Kavi's voice on the phonograph suddenly sped up a little. However, Kavi did not play the video as fast as before to achieve synchronization between the sound and the picture. Instead, he slowed down the playback speed a little.
In the last five seconds, the sound of the phonograph stopped abruptly, but the movie was still playing. The camera on the screen turned to the car lock. Haroldt could clearly see Kavi pressing the button on the car lock and pushing it up, and then the indicator light turned from red to green.
After the play, Kavi turned off the lighting equipment and turned on the lights in the room.
"What do you think?" Kavi asked.
"It's great, it's beyond my expectation. When the senior said that there was a phenomenon of asynchrony between the audio and the picture, I thought it was a serious problem, but it turned out to be not a big problem at all. Even the lip movements matched, except for the beginning and the end.
At the end, the senior wanted to emphasize "remember to lock the car" and the operation of the car lock, so he deliberately slowed down the playback speed, right? Otherwise, there wouldn't be a five-second silence period. "
Kawi: "Because not locking your car may have serious consequences, even though I said in the video that if you don't lock your car, other people's violations will be attributed to you.
But thinking about it... I still feel a little reluctant. Most of the people who use tricycles are farmers who grow vegetables and fruits... Harold, do you think... this rule is too strict?"
"Senior, we initially set the age limit for obtaining a driver's license at 18-50 years old to prevent elderly people with memory loss from violating traffic regulations due to physical limitations.
——Senior, didn’t you also emphasize this in the video? In the future, restrictions will be relaxed, and people over 50 years old will be able to use shared tricycles as long as they take regular tests, cooperate with physical examinations, and renew their driver’s licenses in a timely manner.
There is absolutely no problem in being strict with these young and middle-aged people. If they want to enjoy the benefits, they should at least pay more attention to maintaining public facilities, right?
I would feel sorry if an unlocked bike was ridden by a minor or an elderly person without a driving license, causing a traffic accident and innocent people getting hurt. " Harold thought about the possible accidents that might happen.
Moreover, he is the behind-the-scenes funder of this project, and the money spent on vehicle repairs will be his.
"...I hope that won't happen." Kavi said in a low voice with a frown.
Harold nodded in agreement, and then he said, "But traffic accidents are inevitable. Ships on the sea route may collide with each other. In Xumi City, there are always people pushing wheelbarrows full of fruits and vegetables and hitting pedestrians. Even if humans don't take public transportation, they can still hit themselves and bleed.
However, tricycles travel at a relatively slow speed, and the road we chose is more than 30 meters wide, so there shouldn’t be any serious accidents at this stage.”
But you never know, some people are really unlucky when they are unlucky, like me, Harold thought.
Kavei remained silent. He understood the reason, but when he thought about the people who might be hurt by his project, he felt that he still needed to prepare himself mentally.
"By the way, senior, is the premiere date confirmed tonight?" Harold asked.
"Well, tonight at seven o'clock, if you can't make it back in time, I can go alone." Kavi came to his senses and replied. He knew that Harold had to record experimental data in the afternoon, and it would take at least seven hours to go back and forth.
"How about postponing it to eight o'clock? When I come back, I have a good idea that can effectively improve the efficiency of publicity: why don't we set up two ceilings? I can use communication equipment on the other side to broadcast in real time. After the film is played, we can also exchange everyone's feedback in time. It feels great."
Kawi's eyes lit up: "What a good idea! I will immediately prepare the materials for building a second ceiling. Oh, by the way! I was planning to bring one over so that everyone can experience it up close and experience how to use it firsthand.
Since we have chosen to act separately, can you put one on your side as well? Harold, can you assemble a tricycle?"
No, that really won’t happen.
"This is too difficult for the scholars of Amyrido College, senior." Harold said with a wry smile.
"It doesn't matter. When the time comes, we will transport all the things over, build the ceiling, and assemble the car. We can leave it to the seniors." Kavi smiled confidently.
Senior Kawi is reliable. Harold admired him in his heart.
But he immediately added, "It's just that the first screening may not achieve the effect we want. Everyone's attention may be attracted by the phonograph, projector, and my communication equipment. After all, these devices are also rare in Xumi."
"I have thought about this issue as well. It's okay. We can let it rest for a few more days. Once everyone gets used to it, they will naturally focus on the car. Don't worry, I won't be disappointed because everyone on the ceiling is talking about irrelevant things at night. I'm not a senior who hasn't experienced many storms." Kavi said optimistically.
"Look, I even cut the paper in advance to give to everyone to write their suggestions after the screening." Kavi picked up a stack of papers on the workbench and shook it.
Harold smiled and praised Kavi for his thoughtfulness. In front of his familiar junior, Kavi accepted the compliments without hesitation, and excitedly took out the paper cups, bamboo poles and other small items that he had prepared in advance, and explained to Harold their special uses at night.
After discussing the promotional video to be screened that evening, Harold looked up at the time on the wall clock:
"It's half past twelve. I have to leave for Huacheng and try to be back before eight o'clock."
