What Is VFX? Meaning, Techniques, Process & Careers

Visual effects, or VFX, are used to generate, alter, or mix virtual components that are challenging to photograph. In contemporary cinema and digital production, visual effects are crucial. It consists of computerized environments and CGI animals, object removal, green screen replacement, and cinematic effects.

This tutorial describes what visual effects (VFX) are, how the VFX process operates, typical techniques, tools, talent, and how to begin learning VFX after Class 12. 

What Is VFX?

Visual effects are the process of creating, altering, or combining images that are essentially “created” to be removed from a live-action film. 

VFX can be used to:

• Create digital characters and environments

• Replace or extend backgrounds

• Remove unwanted objects

• Add CGI elements to live-action footage

• Create fire, smoke, water, and destruction effects

• Combine multiple visual elements into one realistic scene

No doubt, traditionally, VFX was associated with post-production. But now, virtual production technologies allow filmmakers to create some digital elements during filming. 

Why Is VFX Used in Film Production?

To avoid danger or spending too much, filmmakers use VFX techniques to make scenes that are expensive to shoot.

Typical uses are 

• Creating fictional worlds: a world set in the future, a digital environment, and monsters.

• Improving live-action shots can include improving scenes, modifying backgrounds, or eliminating objects.

• Creating complex effects like smoke, fire, explosions, destruction, and other simulations.

• Adding scale to the production: a digital environment, building, crowd, and landscape can make a production appear much bigger. 

As a result, VFX is used for both subtle alterations that viewers could miss and dramatic sequences.

VFX vs CGI vs Animation vs SFX

Although these terms are related but have different meanings.

VFX is the broader process, while CGI and animation can be individual parts of a VFX production.

Common VFX Techniques

CGI

Computer-Generated Imagery (CGI) is the process of making images by a computer.

Compositing

Compositing technique is the process of combining elements, like live action and CGI elements, of a shot in post-production. It includes special effects and other components of a shot. Compositing is a blend of art and technology. Some of the elements of a shot may not be finished while compositing, and the artists have to add some parts of the shot using their creativity and experience. The end result should look as realistic as possible.

Green Screen

A green screen or chroma key technology allows the artist to separate an object from its background and substitute the background virtually.

Rotoscoping

Rotoscoping is a technique used to create masks around the people so that specific parts of a shot can be isolated or modified.

Motion Tracking

Motion tracking examines the movement of an object or camera so that digital components can follow it precisely.

Simulations

Digital simulations can create effects such as:

• Fire

• Smoke

• Water

• Dust

• Destruction

• Particles

How Does the VFX Process Work?

A standard set of the VFX workflow consists of multiple steps:

• Planning – define what will be required in the shot for the VFX team

• Filming – record footage and shoot the necessary production assets

• Asset creation – make the assets that will be used for the shot

• Tracking and rotoscoping – prepare the footage and track the shots

• Animation and effects – animate the required assets and simulate the needed effects

• Compositing – assemble the final image or video for the composite shot

• Rendering and review – render the final result and make the necessary updates

Depending on the project and the type of composite shots, the VFX pipeline can vary.

Where Is VFX Used?

VFX is used across several creative industries.

Film and OTT

Different film and OTT projects use VFX for characters, environments, action sequences, set extensions, and cleanup.

Television

Television productions use VFX for environments, effects, fantasy sequences, and visual enhancements.

Gaming

Game creation employs a combination of digital people, backgrounds, effects, and cinematic displays.

Advertising

Brand advertising and promotion make use of VFX and CGI to create products, commercials, digital environments, and other displays.

Music Videos and Digital Content

VFX is also widely used in music videos, branded content, and online video production.

What Is Virtual Production?

Virtual production is the conjunction of traditional physical filmmaking with digital elements and time-saving technologies.

Tools like LED volumes, camera tracking systems, or real-time engines enable filmmakers to experience a digital environment while filming.

A real-time engine such as Unreal Engine allows the updating of virtual environments based on a camera’s position, helping filmmakers make creative choices while shooting.

VFX Specialisations

VFX production involves multiple specialised roles.

Try to experiment with different fields before specialising.

Skills You Need to Learn in VFX

VFX combines creative and technical skills.

Important skills include:

• Composition and visual storytelling

• Lighting and colour understanding

• 3D modelling and animation

• Compositing and tracking

• Problem-solving

• Attention to detail

• Teamwork and communication

Don’t worry about being an expert in all skills. Start with the area that interests you and develop your skills through regular practice.

Which Software Is Used in VFX?

Different VFX roles use different software.

You are not supposed to learn all the tools.  Just pay attention to the relevant skills. 

How Can You Start Learning VFX After 12th?

If you are also interested in VFX after 12th, start with the basics and gradually move to the specialities. 

1. Learn the Basics 

Build an understanding of concepts like compositing, layers, masking, tracking, lighting, and visual effects. 

2. Explore Different Specialisations

Before deciding, try different software like 3D compositing, animation, or VFX to identify what you enjoy doing. 

3. Learn Relevant Software

Choose software based on your selected specialisation instead of trying to learn everything at once.
