How are the film and television special effects made?

As an important part of film art, film special effects provide strong technical support, aiming at creating a unique visual feast for the audience and giving the audience a real feeling of "being there". Hollywood blockbusters make extensive use of post-production technology, especially digital special effects, to create the real world and unusual "fantasy world" and "superman" stories in film and television art.

Some sci-fi films, disaster films and action films with high difficulty and big investment have widely used digital special effects, which has changed "virtual reality" and "future world". The application of these movie special effects is as follows:

1, miniature model

Models of people, monsters, buildings and vehicles are all used to make movie special effects. When the model must be moved, it can be moved in any of the following three ways: manually, mechanically or electrically. It takes a long time to move them by hand, because the model needs to move at least 24 times a second on the screen.

2. Illusions in movies

At normal speed, this movie can take 24 still photos per second. Changing the number of pictures taken per second can create some basic special effects. If you shoot more than 24 pictures per second, you will have a slow-motion effect. On the contrary, if it is less than 24 pictures per second, the action in the movie will be accelerated, and it will be more intense and wonderful.

3. Analysis of technical terms of common special effects such as fluid, particle, rigid body and soft body.

Fluid is based on dynamic calculation, which can produce real fluid motion effect. Fluids can simulate fog, flame, smoke, clouds, water and other effects. Particles are a part of dynamics, and dynamics is a branch of physics, which is used to describe the motion mode of objects in the physical world. Particles are very useful in creating special effects. Particles can be made into spray, flame, dust, smoke and other forms.

Rigid body can make the object model in three-dimensional software participate in dynamic solution (understood as computer calculation), such as the process of objects falling to the ground and bouncing on the ground. In fact, the animator can define this animation process manually according to his understanding of the law of motion.

Software is simply a soft object. In MAYA, through dynamic calculation, objects will get soft motion, such as clothes, elastic skin, curtains or hair fluttering in the wind.
