How are movie special effects made successfully?

Why do movies now give viewers more and more intense visual impact and shock? A very important reason is the use of a large number of movie stunts. Some movies seem dull, but in fact they also use special effects, but you have never heard of them or can't see them at all. With more and more computer-generated images being applied to the production of film works, the film as an art form of audio-visual category has undergone earth-shaking changes, and the charm of its visual effects has sometimes greatly exceeded the film story itself, which is dizzying. Now it's hard to find a movie without special effects.

Film stunt refers to the use of special shooting techniques to complete the special effects of film pictures. In the process of film making, we often encounter some difficult, frightening or dangerous shots and scenes that are difficult to shoot in real life. Because the conventional shooting technology is difficult to complete, it must be done by special effects. According to the production order, it can be divided into pre-production movie stunts and post-production movie stunts. Traditional film stunts rely more on the former, such as trick photography, miniature photography, electronic model stunts, synthetic stunts (including synthetic photography and printing synthesis), physical and chemical effects stunts, stunt makeup and so on. For the latter, there are not many means to complete special effects in post-production. In the past, it was mainly realized by optical printing technology. After the computer is involved in the field of film special effects, the post-production ability of film special effects is greatly enhanced. The content of digital movie stunts is also more extensive and in-depth.

An accident actually created a miracle.

The early film stunt was trick photography, which was the earliest stunt technique. Its birth was purely accidental, and it was discovered by French movie master Georges Méliès when he was filming a play at the Paris Deleux Theatre. When he turned the crank of the camera, the equipment suddenly got stuck. Back to normal after one minute, continue shooting. An interesting phenomenon appeared during the screening: the bus on the screen turned into a hearse, and the man turned into a woman in an instant. This is the freeze-frame technology. In this way, a seemingly accidental shooting accident gave birth to early film stunts. Therefore, Georges Méliès became the "father of film special effects". Subsequently, Mei used a series of stunts such as repeated exposure, slow motion, fast motion and overlapping. Later, I tried split screen technology when shooting rubber man in 1902.

Miniature photography is a trick photography method which takes miniature models as the shooting object. In the process of shooting, miniature scenes, buildings, urban landscapes, spaceships, etc. are made with model props. Actually, it can't be filmed or it doesn't need to be built at a huge cost. Using the perspective principle, shooting with a camera, the effect of seeing the big from the small is obtained.

Film stunts give the film more vitality, make the audience see the past and the future, and realize the director's fantasy and creation. However, the curiosity of human beings may never be satisfied by film stunt masters, and the tricks in traditional film stunts can no longer escape people's critical eyes.

At this time, the computer has been involved in film production, which has also brought great changes to film production, completely affecting the film production technology and production process. From the film preparation (including script writing, story version creation, shooting schedule establishment, etc. ) to the scene, as well as editing and post-production, its influence has never been as extensive and in-depth as it is today, and the most representative is the film stunt.
