VFX: What Is It?
The fabrication or alteration of any on-screen imagery that doesn’t actually exist in real life is known as visual effects (VFX) in the film industry. In the context of a live-action shot, VFX enables filmmakers to construct locations, objects, monsters, and even people that would otherwise be difficult or impossible to capture. VFX in movies usually combines real-world footage with computer-generated visuals (CGI).
In short, Visual effects (VFX) is the process of modifying, creating, or enhancing images for live-action media that was unable to be filmed owing to being expensive, risky, impractical, or impossible to shoot. Visual effects enable the creation of realistic objects, characters, and locations by combining live-action video with VFX.
What Distinguishes VFX and SFX from One Another?
The terms “visual effects” and “special effects” should not be used interchangeably (SFX). Pyrotechnics, artificial rain, animatronics, and prosthetic makeup are a few examples of SFX, which, unlike VFX, are accomplished in real-time while a movie is being filmed. Post-production is when all VFX are added after the filming.
Three Different Visual Effects
Top visual effects firms are staffed with teams of VFX artists that each have their own areas of expertise as well as VFX supervisors. The majority of VFX types may be divided into one or more of the following groups:
- CGI: Computer-generated imagery is a catch-all word for digitally produced visual effects (VFX) in cinema and television. Although these computer images may be 2D or 3D, CGI is often used when discussing 3D visual effects. The most discussed CGI technique is 3D modelling, which involves creating a 3D image of any item, surface, or living being. When artists utilise CGI VFX to create something that doesn’t exist, like a dragon or monster, this is when it is most obvious. However, certain visual effects are more subdued;
- 2. Compositing: Also referred to as “chroma keying,” compositing is the process by which VFX artists blend visual components from various sources to give the impression that they are in the same location. This method of creating visual effects calls for the use of a green or blue screen while filming, which compositors will subsequently replace with another element using compositing software during post-production. An early method of compositing used matte paintings—illustrations of environments or sets that were combined with real-world video—to generate this look. The scene of the Emerald City in The Wizard of Oz is one of the most well-known instances of a matte painting being utilised as an optical composite.
- 3. Motion capture: Also known as “mocap,” this technique involves digitally capturing an actor’s motions and then translating those movements to a 3D model that was created by a computer. It’s sometimes referred to as “performance capture” when this procedure includes capturing an actor’s facial expressions. Putting an actor in a motion-capture suit with visible markers—or, in the case of performance capture, dots painted on the actor’s face—allows for one popular motion capture technique. Motion capture software is then used to translate the data from the cameras onto a 3D skeleton model.
What distinguishes VFX, CGI, and special effects from one another?
Although the terms are sometimes used interchangeably, VFX, CGI, and Special Effects are distinct from one another since they are all made digitally, whereas the former two are captured live and without the use of a computer.
