Edison's sound film scheme was technically quite simple, that is, a phonograph record of the same period was played at the same time as the movie. The sound on the turntable is exactly what you need on the screen. This is the principle of the earliest sound films, and because of the simple principle, it is quite convenient to implement. So after getting Morgan's support, Edison didn't have much time to get the sound movie out. and soon staged their first sound film, The Singer, on Broadway. The film is fairly simple, no more than twenty minutes long, and records a stage performance by a singer. And the dubbing is also very poor by today's standards, and the clarity of that voice is not even as good as the voice in a wired phone. And due to the natural defects of this kind of sound film, there are also some problems with the synchronization of dubbing, the sound and the picture are not completely consistent, sometimes faster, sometimes it will be significantly slower, such as before the singer takes the stage to sing, after the singer. In that part of the stage, during the conversation between the two actors, the voices were completely out of order, obviously it was Peter who spoke on the screen, but the voice that came out was that of Laven, who was closing his mouth.

But even so, the film caused a sensation, after all, the audience of that era was not as picky as modern people, and even when the characters in the movie spoke for the first time, the entire theater audience was shaken. After the premiere, almost all newspapers gave high praise to this innovation.

Of course, the defects of sound and picture coordination have also been noticed, but everyone thinks that such problems should be slowly solved with the progress of technology, and there should be more tolerance for new things like sound films, so they don't dwell too much on this.

However, in fact, this problem is not so easy to solve, especially in the case of the Edison-style projector + phonograph model, which is almost impossible to solve. Because even if you don't consider the problem of manipulation, you only consider the different heat of different materials. The rate of expansion and contraction will inevitably lead to the emergence of this problem, and this asynchronous will be expanded with the extension of the film's time. So even Edison himself firmly believed that the length of a sound film of this genre would hardly exceed half an hour.

"Half an hour, for some funny sketches and stuff, should be enough. It is even possible to express some simple fairy tale dramas. Edison said.

……

"Mr. MacDonald, in accordance with your idea, we have attached a magnetic track directly to this side of the film with magnetic powder to record the sound. In this way, we can read the sound on the track with a head through guò at the same time as the projection, thus ensuring a strict synchronization of the sound. And not Edison-like jokes. Although there were some troubles in the middle, so far, these small problems have been solved. So, Mr. MacDonald, I don't think there can be any problems with this experiment, it's going to be successful, and there are no problems at all. "Tesla is as confident as ever.

"Nikolai, I believe in your abilities." Scrooge smiled and said, "If you don't have a whim in this project, such as wanting to make the film completely three-dimensional or something, and then add difficulty to the project yourself, then I'm sure the original requirements will definitely be difficult for you." ”

"Rest assured, Mr. MacDonald, I have absolutely no nets this time that stuff more than is required. You know, right now, I'm all focused on something called a wind tunnel of yours......" Tesla replied with a smile.

"On that project, if you have any special ideas, you must not hide it from me, we can discuss it together." Scrooge said immediately. Tesla's talent in science and technology is unquestionable, even Edison can't match him in these areas, but when it comes to wasting money on crankiness, his talent is unparalleled, far beyond Edison's limits. Therefore, Scrooge had to keep an eye on him, and guide his whimsy in a useful direction as much as possible.

"Mr. MacDonald, I promise to consult with you as soon as I have any new ideas." Tesla replied, "Okay, it's about to start." Let's check out our latest, hour-long sound movie......"

The experiment was quite successful, and the sound synchronization throughout the screening was very good. As for the content of the movie, it is nothing more than the conversation of several of Tesla's assistants, and the children of his assistants singing together, playing games, etc.

"Hey, Nikolai, you see those young people have children. Aren't you going to hurry up and find a woman? After watching Tesla smile at the children playing on the screen, Scrooge whispered to him.

"Ah......" Tesla apparently didn't expect Scrooge to suddenly say something like this, so he paused for a moment before replying, "Mr. MacDonald, you know, women and children have very, very cute times, but ...... It's just that they also have very, very troublesome times, and ...... Well, in general, there are far more times when people feel troublesome than cute. So, I've always admired those who have wives and have children, and they can endure ......"

Speaking of this, Tesla suddenly thought that Scrooge also belonged to the list of those people he said was "admirable", and it seemed a little wrong to say this himself, so he hurriedly said to Scrooge, "Mr. MacDonald, you know, I can say whatever I want, I'm not talking about you......"

Scrooge couldn't help but smile bitterly, Tesla's grasp of human affairs is far inferior to Edison's, Edison would never say such a thing, even if he said the wrong thing, he would not be so clumsy when remedy. Good thing this person is very useful. And the careful thinking is far less than Edison, and the foundation of mathematics and physics is much stronger than that of the self-taught Edison, and he has more development prospects. can help Scrooge make money even more, so these little things, of course, Scrooge has always been "adults don't see villains". To be honest, as long as there are no financial interests involved, it is not easy to offend Scrooge.

"Nikolai, once the sound and picture are out of sync, I think the film can be used to express something more complex and grandiose, like novels and play......s," Scrooge said.

"Mr. MacDonald, that's a good idea! Unfortunately, my ability in this area is very limited, and I'm afraid I can't help you much. Tesla thought for a moment and replied.

……

"Dasco, how are those texts organized?" After watching Tesla's sound film experiments, Scrooge quickly rushed back to Duckburg and immediately summoned Dasco 61 Popov, who was in charge of intelligence.

"According to your instructions, we have selected the most valuable and touching ones among the characters involved in these articles, and some of them have been edited by the personnel of our propaganda department to form a few first drafts." Dasco 61 Popov replied as he handed a stack of essays to Scrooge.

"Annie 61 Braun?" Scrooge first saw the text on the text clip. He opened the text folder, and the first thing that appeared in front of him was a series of photographs, as well as "portraits" and "self-portraits".

"This girl, Anne 61 Braun, was one of the dead in the Shire concentration camp. We found part of her diary, as well as some photos. "Her father and mother also died in concentration camps, and as far as we know, her father studied art and had a relatively good family before the war. Judging from the photos, this little girl is also very cute, her diary is incomplete, especially the part of the concentration camp is not much, and many of them are missing. Judging from the remaining text, compared to a 14-year-old girl, her writing level is not bad......"

While listening to Dasco's 61 Popov presentation, Scrooge looked at the materials, and after a while, he looked up from the text and asked, "Why are there no pictures of her in the concentration camp and when she died?" ”

"Mr. MacDonald, not many people will have time to take pictures since the war began, and there is no possibility of photography in the concentration camps. And as far as we know, her body was removed in batches before we entered the Shire concentration camp. So we didn't have her in the pictures we took of the deceased. Dasco replied respectfully.

"Are there any of the bodies of the deceased we photographed who are similar in age to her?" Scrooge continued.

"There are a few, but they are all quite different from Anne's appearance." Dasco replied.

"Show me those pictures." "All the pictures of the deceased who were her age...... No, show me all the pictures of the dead! ”

"Yes, sir." Dasco 61 Popov retreated. It was only in the afternoon that he arrived at Scrooge's office with a pile of materials.

"Mr. MacDonald, here are all the pictures you want." Dasco 61 Popov gave a large album to Scrooge.

"Hmm." After a while, Scrooge pointed to one of the photographs and said to Dasco 61 Popov: "Let your people enlarge this photograph and remove the lower half, and think it is a picture of Anne 61 Braun." ”
