How are the special effects made in movies?

Thank you very much for answering this question.

1, basis

At present, Hollywood is the best place to make film special effects, which involves a country's industrial base and film production technology, and the soul of science fiction films is these amazing special effects. First, the general environment is built from the props, costumes, scenes and actors of the film, and the special effects of a good sci-fi film account for at least 75% or even 90% of the film, and almost all of them are sci-fi and fantasy, requiring computer graphics processing, such as biology. Then the animator scans according to the details and finally draws a sketch from the coloring. Moreover, this is only the most basic part of the work. In addition, according to each character in the movie, we need to customize many body double and many special effects to create a highly realistic digital miniature vision. For example, Gollum, an elf character in The Lord of the Rings, is a product created by a realistic CG with a real person behind it. Andy serkis created Gollum's voice and movements behind the scenes, and needed to capture various facial activities and other movements in the film. These parameters have been sent to the camera and entered into the computer. After CG processing by the animator, they became Gollum, but you didn't see andy serkis in the film.

2. Company

Of course, good special effects come from the construction of basic motion capture, characters, modeling and scenes. And powerful processing tools are needed to solve the combination and re-creation of these materials. For example, the famous Vita Digital in the industry, and the visual effects in famous movies such as The Lord of the Rings Trilogy, King Kong and Avatar are all from Vita's production team. Vita Digital won the Oscar for Best Visual Effect five times. For large-scale war scenes, Vita Studio has specially developed a large-scale crowd simulation computer program, which can create automatic combat animation, as well as a large number of simulation modeling and simulation software. For example, in Avatar, Vita must post-synthesize the stereoscopic images taken by two 3D cameras. In order to accomplish these tasks, Vita uses a server cluster with * * * 4,000 servers and * * * 35,000 processors, which is three times that of "Lord of the Rings 3". This server cluster can even rank among the top 200 supercomputers.

The special effects in movies are all made of software, and there are too many softwares that may be used in movies.

3D animation software: Maya, XSI, 4D cinema, Houdini.

Special effects synthesis software: flame, nuclear explosion, explosion

For example, Avatar ... the scenes of people, plants and buildings were made by 4D Film Company.

Some shots, such as explosions and collapses, are made of flames and finally synthesized with NUKE.

Another example is Titanic, which was made by MAYA and synthesized by a software called SHAKE. Now it has been discontinued.

Another example is Star Wars, Lightsaber, and those buildings and cartoon characters, which were made by 4D Film Company and then synthesized by flames.

Pre-shooting+post-digital technology synthesis = special effects. Simply put, it is to cover the place where special effects are to be added with a green film curtain, and then make it with digital technology.

In fact, there are very few special effects that cannot be done at present. For example, the effect of adding fire to the gun or spraying blood on people in the later stage is no problem, but it still takes some time and energy to be realistic and it is impossible to distinguish between true and false.

General directors like to avoid special effects when they can really make them up, because it is more "real". . . . But now truth is a very relative word. . . Because as long as the special effects are done, it can be done that no matter what kind of experts can see whether they are special effects or not. Therefore, the use of special effects is basically the director's choice, and each has its own advantages and disadvantages. Adding a device to clothes will save a lot of time later, but the device needs money and supervision. If it is troublesome to change clothes once, it may take a long time to make, but it will save a lot of manpower and material costs. If you are willing to invest time, money and energy in the two methods, you can achieve basically the same effect.

How are the special effects made in movies?

I believe that after watching this video, you will clearly understand the truth and process. This video was edited by Anti-Brain Studio and explained by "Better than Banana". ...

The special effects in the film are post-produced. This technology-intensive industry involves many professional fields. The general process is the simulation effect made by computer according to scene modeling, animation, lighting, special effects, materials, rendering and final editing. And each department has different fields. For example, special effects are divided into water, fire, particles, sand, cloth and TD. . . . .

Anyway, the late stage of film and television is not something that 1-2 people can do. A movie assumes an investment of 1 100 million, and then it is calculated according to 30 million later.

Most movies are only 90 minutes at most-up to 2 hours =

Special effect is an illusion created by using a lot of manpower, material resources, financial resources, computers and other equipment.

At present, most of the special effects in movies are made by computers.

It was not made, but made by a later professional team. It is time-consuming and laborious, and it costs a lot of money. A few seconds of shots may cost millions, so some low-effect movies made to save money are neither fish nor fowl, and they are not comparable to American blockbusters at all.

If you are a professional in this field, you can look for movies without special effects. After watching this video, you will feel that this actor is just like a "fool". A hot scene is basically an actor dancing in front of a green cloth, and special effects are added to the green cloth later.

Those special effects must be done on the computer, although it is not clear how to deal with them. Now mobile phones can also be made.

Green cloth, then post-production, Ae and other processing software.

Special effects? It's made by software, basically special effects made by 3D software, and also made by software such as AE. Special effects are all added later.
