How to do special effects

Visual effect (VFX for short) refers to the integration and processing of elements in the real world and the virtual world by means of digital technology, synthesis technology and photography technology, so as to create various visual effects in film and television works. Widely used in film and television, animation, games and other fields. Here are some basic steps to do special effects.

plan

Before you start making special effects, you need to plan and budget. Planning includes determining the types of special effects, scenes, required resources and technologies, and so on. The budget includes expenses, time, etc. And need to make a reasonable budget according to the actual situation. Planning and budget are the basis to ensure the smooth production of special effects.

shoot

The first step of special effects production is shooting. In general, shooting is divided into two types: live shooting and green screen shooting. Real-life shooting refers to shooting in the actual scene, and green screen shooting is shooting in front of the green screen background, and then synthesizing the virtual scene later.

post production

Post-production is the core of special effects production. In post-production, the following steps are required:

(1) Data collection and sorting: sorting out the shot materials, including video, audio and pictures.

(2) Motion tracking: Through motion tracking technology, real and virtual scenes are matched to ensure the authenticity of special effects synthesis.

(3) Modeling and animation: According to the actual needs, use 3D modeling software to model and animate.

(4) Rendering: Rendering the animated material to generate the final visual effect.

(5) Synthesis: Synthesis of rendering materials, including color adjustment, lighting effect, angle adjustment, etc.

Review and revision

After the post-production is completed, it needs to be reviewed and revised. Review refers to the inspection and evaluation of completed special effects to determine whether the expected effect is achieved. If the expected effect cannot be achieved, it is necessary to modify and adjust until the expected effect is achieved.

Output and release

After the production of special effects is completed, it needs to be output and released. Output refers to the encoding and compression of the material after the completion of special effects production to generate the final film and television works. Distribution refers to the release of film and television works to various media platforms for the audience to watch.

In short, the production of special effects requires planning, shooting, post-production, review, output and release. Special effects production needs a certain level of technology and art, solid technical and professional knowledge, as well as creativity and imagination, in order to create wonderful visual effects.
