"Did the police catch the murderer?"

Hearing Wang Yiyuan's question, Wu Xinghui closed his eyes painfully and shook his head. Pen "Fun" Pavilion www.biquge.info

"Isn't there a surveillance video?"

"The art school was on the second and third floors of a rented office building, and the camera was installed at the entrance of the building. Judging from the video, my sister met the robbers at a distance of no more than 50 meters from the office building, although the two robbers did not wear hats and other things to hide themselves, but the clarity of the camera was not high, and the faces could not be seen clearly at all. ”

"Can't you zoom in? That's what happened in the movie, the police got the surveillance video, and then the technicians went out, and they instantly zoomed in to see the face clearly and compared it with the data in the database, is this fictional? Am I misled again?"

"It can't be said to be fictional, and the screenshots taken by high-speed, high-definition cameras can still be enlarged into very clear photos by technical means. But the camera installed at the entrance of the office building by the school is an ordinary camera with 24 frames, once it is slow, it is not clear, and the pixels of the screenshot are even more miserable, and the police can only barely judge that the two people should be male at that time, and see what they did at that time, and the faces are really indistinguishable. ”

Wang Yiyuan also sighed when she heard this.

As a movie fan, of course, she knows that in the earliest films, a still image was called a "frame", because the visual persistence of the human eye happened to meet the standard of 24 frames per second, so in order to save costs, 24 frames per second became a common format for motion picture film. Television, on the other hand, typically plays at 30 frames per second, and this has been the case for many years.

But this low-frame-rate format has a big drawback: when shooting high-speed moving shots, the image will be blurry and shaky, so in 2012's "The Hobbit" co-produced by New Cinemas and MGM, the producers used 48 frames per second to shoot some of the footage, which also conveyed the message that high-frame-rate movies were coming to the stage.

Nowadays, many camera equipment on the market has also begun to play the brand of high frame rate to attract customers to buy, but in fact, due to the limitations of sensors and transmission formats, in fact, most of the so-called high frame rates are just a gimmick, and they cannot achieve high-definition and high-speed effects at all.

This is true for the camera equipment used by specialists, not to mention the ordinary surveillance cameras used by the private sector.

"Have the police opened a case?"

"The case has been filed, but since my sister left, several days have passed and there is no new news, so it is estimated that it will be difficult to trace. Wu Xinghui said seemingly plainly.

Wang Yiyuan understands that although Wu Xinghui does not seem to show too much sadness on the surface, he must have been very uncomfortable in his heart.

Like Wang Yiyuan, he used to call Wu Yueying "Yue'er", but since Wu Yueying's death, he never called out that title again, and when he mentioned her, he also said "sister".

Wang Yiyuan didn't know how to comfort Wu Xinghui, so she had to continue to ask about the situation at that time.

However, as Wu Xinghui said, he did not know much about the situation at that time, and the information he could provide was extremely limited.

After arriving at the airport, Wang Yiyuan asked Wu Xinghui to wait in the pick-up hall first, and he drove to the parking lot.

She called Ni Jun, and Ni Jun quickly found the information she wanted: the cause of Wu Yueying's death.

According to police records, Wu Yueying was stabbed into the abdominal cavity from the left rear twice with a sharp weapon, resulting in penetrating wounds on the left kidney, adrenal gland, and spleen, resulting in massive blood loss and death.

It really looked like it was just an accident. However, Wang Yiyuan knows Wu Yueying's character very well, she will definitely not be the kind of person who will fight against others because of money, the robber is seeking money and not life, why don't you grab the bag and run, but stab with a knife?

Wang Yiyuan couldn't help but think of her previous speculation about the accident of organ donation, but she quickly shook her head and vetoed her idea.

If there is really a shady scene, if someone wants to obtain organs from the death of Wu Yueying, who is a body donor, they should adopt a more professional method to better preserve Wu Yueying's body organs, and will not choose to use this street gangster method, this time Wu Yueying was stabbed, which led to damage to some organs, in case the stabbing is in the wrong place and hurts other organs, isn't it a waste of thought?

Maybe it really was just an accident. Wang Yiyuan doesn't know whether she should be happy that there is no shady existence, or whether she should be sad that there is one less comparable object.
