Visual Effects (VFX)

Film lexicon | What does VFX mean? What are visual effects?

Definition: Visual Effects (VFX)

VFX, short for visual effects, refers to effects in the film, which in post-production, generated digitally with computers become. The difference to so-called SFX, short for special effects, is very important here. The latter are created on the set itself to make the presentation as realistic as possible. Nowadays, SFX are very often combined with VFX in order to produce cheap and correspondingly realistic results.

Application of visual effects

Visual effects are nothing more than digital effects in film productions these days. They are mostly used to improve existing film material or to achieve certain effects. They must and should appear real to the audience Depict the plot of the film in a believable way. There are also visible effects and invisible effects - also known as visible or invisible. Visible effects are noticeable, such as the transforming cars in Transformers. The viewers cannot see invisible effects in the finished film, such as the replaced green screen. Invisible effects can of course also save costs. The backdrops are then built on the computer.

How to create visual effects?

In pre-production, the visual effects for post-production are planned in advance. In the meantime, the camera settings and the lighting are also being developed; after all, the best conditions should be created for post-production. Before applying visual effects, the effects are first created by rear projection or double exposure.

Usually a previz, that is, a rough visual implementation of theStoryboards, created. It is the basis for development the images of the film. Then, while the film is being shot, visual effects are recorded with a green screen. But there are other techniques that are used in the field of visual effects, such as match moving. This is used when 3D elements inserted into a shot with a moving camera should be. When modeling, geometric objects are created as follows:

  • "Rigging" (working technique in 3D animation) is used to create digital characters.
  • "Shading" can be used to simulate surface properties of objects in 3D.
  • "Rendering" is the rasterization of 3D elements into a two-dimensional pixel image.
  • "Texturing" is used to cover 3D elements with texture maps.
  • With "Matte Painting" you create backgrounds.
