After telling Felipe Raschel what to pay attention to during shooting, and exchanging opinions with Franco Miller, Murphy enters the set surrounded by the green screen. Three photo assistants are setting up the camera. Helena espozera takes the assistant to make the final inspection of the set green screen.

This kind of green screen shooting, which relies more on the special effects of later stage, undoubtedly greatly reduces the workload of preparation and shooting.

Looking back from Helena, Murphy looks to her left and suddenly sees a familiar girl coming.

Her golden hair is simply combed into a ponytail at the back of her head. She is wearing a small denim suit. Some of her hair is gray and old. With a pair of brown leather boots on her feet and a pair of eyebrows raised on her face, she shows her unique wildness.

This is Murphy think for a while, finally remember, compared with the impression, she grew tall, with more wild.

"Hi, Murphy," said the girl politely before she came up. "Long time no see. Do you remember me?"

"you are" Murphy watched her getting closer and closer, "you are Marguerite Maggie"

Marguerite walked to Murphy four feet away and looked at him askew. "I was on the phone with you yesterday."

"Oh, I remember." Murphy apologized with a smile, "recently too busy, some things always forget."

Seeing the opposite girl nodding gently, he politely asked, "how come I'm in Los Angeles"

"I've had my summer vacation." Margaret curiously looked at the green screen around her. "Come here for a tour. I heard you are making a movie. Let David take a look. I haven't seen a movie yet."

She held out her hand and pointed to the wide green screen behind Murphy. "What are these used for"

"instead of shooting the background?" Murphy simply said a few words and asked, "do you want me to show you around?"

When he was in Australia, he was entertained by the other party, but now he comes to his site. Of course, he can't wait.

Marguerite thought about it, nodded her head gently, "OK."

Murphy beckons Paul Wilson to find a female assistant to take Marguerite around.

As soon as the little girl left, Murphy heard the sound of footsteps behind her. James Franco, who was not filmed today, came over in casual clothes.

He stood next to Murphy, looking in the direction Marguerite left, and asked, "who's this"

"don't think about it, Jim." Murphy warned, "she's David Robbie's sister."

"Hey, Murphy, you think too much," James Franco said innocently, spreading his hand. "I've got lily. I'm not interested in anyone else."

Murphy slapped him on the shoulder. He didn't want to see his crew fighting.

Soon, the shooting began. Today's shooting is mainly an action play, about the scene of seisrogan's muffle attacking the police.

The shooting takes the green screen as the background, and the special effects are also added in the later stage. Unlike ordinary green screen shooting, Murphy will use high-speed photography technology here.

In the early stage of preparation, he did experiments with Philip Raschel, and his experimental lens was also approved by Frank Miller.

The style of the whole film will definitely be consistent with the cartoon, which Murphy will not change. However, the individual scenes will also be adjusted appropriately. For example, in the cartoon, the action play is completely fragmented. How to make it more attractive and more like the style of cartoon can bring people a different kind of stimulation

in the final analysis, the film and cartoon still need to be improved It's different.

"Fran, action plays in comics are different from action plays in movies."

standing behind the director's monitor, Murphy and Frank Miller, the nominal director, said, "in the background of thick ink and heavy color, like black and white oil painting, the blood and windy corpses in the cartoon can bring stronger visual impact in slow motion. You can also see in these previous experimental scenes, and the effect is very good Good

"I mean," Frank Miller raised his cowboy hat, "these scenes need to be properly controlled. After all, these are not the selling points of comics."

Murphy nodded. "I know it's going to be moderate."

Without restraint, the film will not be R-rated, but nc17.

Frank Miller is old and mature. He can see that the situation in the crew has exceeded his estimate. As long as the style and general direction of the film do not deviate from the track of comics, he rarely expresses his opinions recently. Moreover, no matter what changes are made, Murphy, the director, always consults with him for the first time and shows enough respect.

What's more, from the perspective of high-speed slow motion in the preparatory stage, the effect of the action play is really excellent.

After the actors and other departments were ready, Murphy quickly called out to start shooting. The shooting seemed rather boring. The ugly looking Seth Logan and several stunt actors danced in front of the camera according to the routine of action guidance. Within a few minutes of shooting, they had to stop and readjust. In particular, Seth Logan's make-up was very troublesome, and they had to make up if they touched it.According to Murphy's request, the film crew's Philip Raschel and two photo assistants operate three of the latest Sony digital cameras to shoot every shot in the end scene at a high frame rate.

In fact, it's not complicated. Murphy wanted to integrate the high-speed and slow motion camera shooting method used by the 300 Spartan warriors into the fight scenes of sin city.

Although the Spartan three hundred warriors are more colorful than the city of sin, the background pictures of the two works are similar to some extent, and Murphy is far more restrained than Zach Schneider, only using this shooting method in action plays.

Action drama is not the key to the success of a film, but it can attract the audience.

Of course, the use of high-speed slow mirror way to shoot action scenes, is also more troublesome work.

The slow shot in the film is not simply slow play, it is the most low-level way to produce slow shot effect. Murphy uses high-speed shooting with high-definition digital camera, and then slow play.

The normal camera shooting is 24 frames per second, and the film is shown at 24 frames per second. However, when shooting the action scene of Seth Logan, the shooting speed of the two digital cameras is 96 frames per second, and the shooting speed is changed to 12 frames per second, so that excellent slow motion lens can be easily obtained.

Of course, such a setting is not out of thin air, but is directly related to the recognition of the human eye.

At present, the frame rate of movies is adjusted to 24 frames per second in photography and projection. This parameter is consistent with the time resolution of human eyes. Therefore, although the movie is not continuously projected, it forms a coherent image in human eyes.

It is precisely because the human eye has such a limitation that the human eye can not fully capture some higher speed motion. At this time, it needs the help of external force to slow down the motion, so as to ensure the complete viewing of high-speed photography technology, which is the product of this.

High speed photography is a kind of photography method with fast shooting speed and short exposure time. Depending on the technology of "fast shooting and slow playing", the fast changing motion process will be slowed down to the time resolution of human vision, so that people can observe. This also means that in high-speed photography, the shooting frequency must be synchronized with the speed of object motion change, and the faster the change, the higher the shooting frequency will be required.

This technology is widely used in Hollywood, such as Michael Bay's opening funeral in high-speed slow motion, and the bullet time in the matrix.

At the end of two hours of shooting, Murphy called the crew to stop and let them rest for half an hour, while he and Frank Miller and Miramax's editor Lars beinte checked the shot that had been shot.

For Frank Miller, the background is full of green screen, slow motion without special effects. It's really not good-looking. It's far less than the scene that Murphy showed him when the knife passed through the human body with blood.

But even a layman, Frank Miller knows that to achieve that effect, he has to go through more complicated post production.

In fact, Murphy and rasbeinte are looking at it carefully. What they are mainly discussing is the editing point of the action lens.

All action shots will be shot with multiple cameras to increase the editing materials from different angles. The editing points of action shots must be able to reflect and strengthen the emotional power of the action scene, which is also one of the basic principles of action shot editing.

"The reaction and action guidance of the characters can certainly lead the plot to develop in different directions."

Sitting behind the director's monitor, Murphy watched the dozens of scenes repeatedly played on the monitor that muffle was killed because of his parole officer, and said to rasbeinte, "it should also help bridge the position and continuity of the fault, make the slow motion part lively, and skip the part you don't want. Ideally, it's best to clip the important people in the scene, including reactions from participants to bystanders, into the sequence. "

Rasbeyin nodded. "I don't think the camera shot by push-pull and shake can move at the same speed. If they are cut together, it will lead to worrying wrong scenes."

"Well," Murphy fully agreed with raspeint, "pay attention to that."

What else did he want to say? Suddenly he saw Paul Wilson come over in a hurry, as if there was something urgent.

"Murphy," Paul Wilson tried to keep his voice calm, "there are two people outside who claim to be from the directors' Union and say that our crew has violated the rules of the directors' union"

Murphy immediately stands up, looks at Frank Miller on the other side, frowns and says, "Paul, you go to inform bill and Erica." It's not finished yet.
