Coquettish Rebirth

"Combine the single-frame photos taken by the camera, and then make supplementary frames? Finally, insert them into the movie? Is this really feasible?" I was confused then!No wonder he wasn't confused, you need to know that between one frame of this single and a moving image, it doesn't mean that simply putting 24 frames together makes a smooth movie!

Why do you say that?Just like the games of later generations, what is the concept of 24 frames per second?And movies have always been 24 frames, what is this concept?Why does a game with 24 fps already make people feel stuttered, while another 24 fps makes people feel that it is not stuttered at all and is very smooth?There is a problem of frame generation time - in simple terms, for a game with 24 frames per second, 23 frames are completed in the first half second, and one frame is being made in the second half second, so how can there be no Tonka feeling?right?But for movies, that is the average speed of 24 frames, which of course feels smoother!

But there is another question, that is, why are games and other things of later generations basically set to 30 frames per second or 60 frames per second instead of 24 frames per second like movies?There is a big problem here-that is, in the frame page of the game, every frame is still!No, this explanation is a bit messy, it should be said that every frame is clear!And what about movies?This is not the case. Because of the lens and the concept of the shutter, when shooting a high-speed moving object, the speed of the "shutter" is not as fast as the moving speed of the object.As a result, what is left on the photo is an afterimage, and there is a smear!

For example, when taking a picture of a 1-meter race, it is taken with an ordinary card camera, and the contestants will always be blurred when they run!This is not due to hand shaking, but to the shutter—the athlete ran [-] meter away from the time the shutter was opened to the time it was closed, and this fell on the film, of course it was an afterimage!It's like a professional sports photographer taking shots of athletes standing still in the air, all of which are shot with a shutter speed of a few hundredths of a second or even a thousandth of a second!Only in this way can the athletes be clearly fixed on the photo without any afterimage or smear!

Then again.What about this movie?It can be understood as putting 24 photos with smears in a row, then because the human eyes have a short-stay effect, they will automatically become coherent, and you will feel that this is a coherent running movement.But because of the images made by computers.Each of them is clear in itself.If it is still 24 frames.Then it's a bit incoherent!More numbers are needed to make up for the rush of this kind of movement - it's like taking pictures of athletes with a shutter speed of one thousandth of a second. Although each picture is very clear and there is no afterimage, it is obviously necessary to use a thousand Zhang will make people feel that this is a complete second!If only one hundred sheets are used.Obviously it feels a bit too fast!

Therefore, Jia Hongjian said at this time: "Although a single photo, especially a photo taken with a relatively fast shutter, is still different from a single frame of a movie, after a supplement of computer technology, we are It is enough to make up the effect of the number of frames in the middle! And you know, there is a very smart way in it! Because ours is slow motion, we have 60 photos, each of which makes up one frame in the middle, there can be 120 frames , this is equivalent to 5 seconds of the movie! Then, these 120 frames may actually be shot within 0.1 seconds, then when we make up for the missing frames, the screen may be played at a speed of 24 frames, which will follow the The 24-frame footage shot on the film itself will have a sense of fragmentation, and it will feel like it is a bit stuck or not so smooth, but we are going to make a bullet-time slow motion! Originally, we wanted to put it in 5 seconds What was put in it was originally the actors hovering in the air! Then how could the audience notice something was wrong? They couldn’t even notice it!”

Awesome!At that time, the president of Nikon's eyes widened, and he almost gave Jia Hongjian a thumbs up!That’s right, if this technology is used in the process of shooting normal running, if the things captured by these 60 digital cameras are not movements within 0.1 seconds, nor are they doing slow motion, but after making up the number of frames , that is, if the movement speed is the same as that of the normal film, then the connection will definitely be a bit surprising!After all, one is an action with precise movement, and the other is with an afterimage!This sense of movement is different!But if it is made in slow motion, and it lasts for several seconds, and it is even combined with a camera cut, then the audience may not feel this kind of sensory surprise at all!

wipe!This can be said to be to maximize strengths and avoid weaknesses, isn't it!This idea is so clever!Nikon's president looked at Jia Hongjian at that time, and he really couldn't figure out how a person like Jia Hongjian could come up with such an ingenious trick!We must know that Jia Hongjian existed more as a young entrepreneur in Japan!Such a Jia Hongjian, is promoting various things in Japan, and then robbing people of all kinds!How could such a genius in business be also a genius in the film industry at the same time?How could you come up with such a miraculous and seamless method?

But at this time, the president of Nikon suddenly thought of something!whats the matter?You should know that Nikon has very high expectations for this d1!what to expect?It is to reverse the high-end industry users all over the world—for example, all kinds of advertising still pictures, such as various sports photographers such as various newspaper reporters, etc., let them give up the traditional film SLR, and use this d1!So how can they convince those industry customers to switch?Is it because their products are good that the other party must change them?Unless it can make the other party feel that the advantages brought by the new product are far greater than the "cost" of replacing the old product, why do they want to change?For example, it costs us $6000 to change one. If your new product can only bring me $10 in 3000 years, why should I change it?And you must know that there is still a problem of rapid upgrading of digital cameras-the number of popular entry-level digital cameras for civilian use last year was only 30, and this year it will be 100 million.Who knows if it will change to 1000 million in five years?If I use traditional film now, the resolution of film is much higher than digital!Theoretically, film can be enlarged infinitely!But not digital!So in a way, as long as the traditional machine is not broken, I can use it for a lifetime!But what about your digital camera?

So Nikon must prove in various ways that it is indeed good to change their d1!So, in order to convince other industry users, should they make a good publicity now?So isn't this an opportunity for publicity?So at this time, the president's mind suddenly started to work rapidly, and then he said: "Then Mr. Jia, since you are so ambitious, you want to use our Nikon products to make a breakthrough. I think this is very similar to our Nikon culture! So, we Nikon want to invest in this movie of your company! Yes, sponsorship! So not only these 60 cameras, but more as long as What you need, we can provide for free! Even. We can also temporarily change our products according to your requirements. It is not impossible to redesign for you! In addition, if you have any software requirements, such as in the control For some camera requirements, our company can also send a technical team to help you solve problems for free!"

That's right!For Nikon.This movie is the best promotion!etc!If they expect the film to be promoted so much, doesn't the president want to read the script or something?Doesn't he want to see who the lead actor is?It does not matter!The important thing is that they have developed a brand new use of one of their products through Jia Hongjian's brand new shooting method!Then through this use, show it to other industry users to show the superiority of their products!Even, with the development of software, many interesting functions may be developed-for example, can software be made to meet the typesetting and printing needs of industry users?Even if others have done it, can they make their stuff seamlessly connected with other people's?

After all, users in this industry are not ordinary consumers, they did not come based on advertisements!It's not that everyone who advertises is well-known!It's like ibm, how many ads are there for ibm?It's just that one or two advertisements are released every year to let ordinary people know that their company is still there and that they have new products. Ordinary people will know what specific products IBM has?Ordinary people will know how much IBM's plan is priced?Ordinary people will know how much more ibm gives away for free today during the holiday, and there is no price increase for the increase?Won't!Those things are for ordinary consumers, for enterprise users or industry users or professional users, they have their own reputation, they have channels to understand, and they pay more attention to details and professional things , not how loud your advertisement is!It's like Nike's basketball shoes are good, but the little star will not say that he will use a certain shoe because Nike's advertisement is good, but he feels comfortable wearing this shoe, and he thinks it will not affect his playing, or He will only use it if it is helpful for him to play!

So from this point of view, even if Jia Hongjian's movie is a mess, and the number of viewers is only 1000 in the end, it will not hinder their Nikon company!They turned around and edited the scenes from the extras of the movie, made a short film and showed them to the industry customers they wanted to win over, and then they might be interested in the new professional role revealed in the extras!People won't buy the movie just because it's not famous, and they won't buy it just because the movie is famous!

Hearing what the president said, Jia Hongjian was stunned for a moment!He originally wanted Huaxia Hi-Tech to study this system—that is, the program-controlled camera control system.Is this system difficult?In fact, it is not difficult, that is, the program precisely controls the shutter of the machine through the circuit in chronological order. ok!At most, it is due to the problem of craftsmanship and craftsmanship, which may cause the stuff welded by hand to be inaccurate or something, but it definitely does not mean that it is so difficult that it will take a long time to get it done!

So if this matter is not left to Huaxia Hi-Tech, but to Nikon, Jia Hongjian thinks it's okay - anyway, it's impossible for him to let Nikon handle the frame-filling system behind it!This kind of thing was done by the special effects team in his company's DreamWorks and the animation team of Pixar!Therefore, at this time, Jia Hongjian readily agreed to the request!
