Chatty Hollywood

"The biggest difference between movies and the scenes we see in our lives is that they are not continuous."

Sheldon began to give Emily and Leonard Kopp with a smug face,

"Just like discrete particles can accumulate into a complete object, a movie is actually composed of similar pictures one frame after another. Because of the characteristics of the persistence of vision of the human eye, when we see 24 When the pictures are framed, our eyes will automatically help us string them together to form a smooth continuous picture, that is, a movie!"

"So movies are also called "24-frame art"!"

Emily sighed.

"But what does this have to do with that female ghost?"

"Of course there is!"

Sheldon is very confident in his guess, he looks like a good teacher to Emily and Leonard,

"Think about it, if there are 24 consecutive frames in one second, our eyes can help us string them into a continuous frame, but what if only 8 of them have the female ghost in them, but the other 16 frames don't?"

Seeing Leonard and Emily looking thoughtful, Sheldon gave the answer directly,

"The image of the female ghost is in our eyes, it will be diluted by other images, and finally we can't see it!"

"But on the other hand, in fact, we have seen the image of the female ghost after all. Even if the eyes can't notice it, the brain will eventually feel it."

Leonard also understands now,

"That's why when we watched it for the first time, we always felt that something was wrong."

"Those places are the shots where the female ghost actually appears."

Emily suddenly realized, but soon became confused again,

"But even so, it can only explain why we felt something was wrong when we watched it the first time. But why can we see the female ghost again when we swipe it for the second time?"

"this……"

*******************

"That also uses the persistence of vision of the human eye!"

On the way home, Charlotte was also explaining the last technical mystery to Charlize,

"When you watch it for the first time, people can't see the picture of Alexis. Although it is a bit strange, it is not a difficult technology in essence. When many TV stations broadcast football games, they will occasionally insert A few frames of landscape paintings, although limited to the number of frames and invisible to everyone, can be used to calm down the restless mood of the fans."

"In contrast, it is the most difficult thing for the second-brush audience to see the pictures about Alexis."

Having said that, Charlotte shrugged her shoulders,

"Anyway, as far as I know, using normal technology, it is impossible for people to see completely different images when they look at the projection of the same set of films—"

"Unless you use two different sets of film!"

Charlize expressed her guess, and she has actually been curious about this question for a long time.

"In that case, in addition to the second-time viewers, those who watched it for the first time will also see it!"

Charlotte smiled and shook her index finger,

"In it, spells are actually applied."

"Spell!?"

"To be precise, it should be hypnotism. It's just that no ordinary hypnotist who doesn't know magic can use film to hypnotize him, no matter how powerful he is."

Charlotte shrugged.

"So, it's okay to call it a spell."

"Hypnotizing audiences through movie screens?"

Charlize's curiosity was really aroused now,

"Can you tell me, what exactly are you hypnotizing?"

"certainly."

Charlotte has no intention of hiding,

"Though I know magic,

But when it comes to hypnosis, I'm not much of a master. At least, I don't have the ability to hypnotize a person and make him think he is a duck. What I am good at is just to make people's memory of sound and image deeper and more real through hypnosis. "

——Only with the help of this kind of hypnosis, can I impress others with the spells and then believe that the spells really have magical powers when I chant those spells that are completely fabricated to deceive people.

——And what's even more ridiculous is that if they believe it, the spell will really have magical powers, making my spells more effective.

Charlotte complained about the mystery and idealism of his spell system, but he didn't explain it to Charlize.

"In this "Fatal Turn", I just hypnotized the audience and let their brains remember the image of the female ghost, that is, Alexis appearing deeply-even if they watched it for the first time You can’t even notice the pictures.”

"But what's the point of doing that?"

Hearing this, Charlize felt even more confused.

"Of course it makes sense! Just imagine, if you have a deep memory for a certain scene in a movie, does it mean that when you watch it next time, just seeing the scene in front of you, you will realize in advance that this scene is about to arrival?"

"this……"

Charlize tilted her head and thought for a while,

"It seems that this is really the case!"

"Under my hypnosis, the audience who watched it once did not notice the scenes of Alexis, but their brains, or subconscious minds, deeply remembered those pictures. And when they watched the second Over time, the pictures in the subconscious memory will appear in advance, interlaced with the pictures played on the big screen, and finally form the visible picture of Alexis."

"Staggered?"

Charlize's expression was obviously a little dazed.

"not understand?"

The blond girl nodded.

"Let's put it this way, it's equivalent to a comic book with only 12 pages. I made another copy and mixed it with the first one page by page, so that the number of pages is doubled."

Charlotte gave a simple example,

"Among the 24 frames played in one second, Alexis will only appear in 8 to 12 frames. At this time, because the number of frames is too small and it is diluted by other frames, the eyes can't see it naturally. "

"But when those viewers who watched it once swiped it for the second time, the images in their subconscious memory and the images they saw for the second time added up, and Alexis appeared in 16 to 24 frames within one second. The frame rate range is already visible to the human eye.”

"In other words, it is a picture similar to hallucinations formed by combining the picture in people's memory and the picture seen in front of them?"

Charlize tried to sum it up,

"Why do I think this is brain supplement?"

"It's not wrong to say it's a brain supplement!"

Charlotte simply admitted Charlize's statement.

"My method is originally the result of the combined effect of the subconscious memory of the human brain and the residual visual effect of the human eye. You are right to say that it is a brain supplement."

"Actually, this kind of phenomenon is also very common in reality—sometimes when we look at something, we will preconceive what it is, and then when we observe it with our eyes, we will often feel that it is very similar—this is human The result of the joint action of my visual and subconscious memory is not too different from my technique!"

"So that's it! This is really like a magician's technique!"

Suddenly Charlize realized.
