Types of VFX Used in Movies
Have you ever wondered how movies create massive explosions, futuristic cities, imaginary creatures or environments that don't exist in the real world?
The answer is often Visual Effects, or VFX.
VFX allows filmmakers to create, modify and enhance visuals that may be difficult, expensive or impossible to capture with a camera. From blockbuster movies and OTT content to advertisements and music videos, VFX has become an important part of modern filmmaking.
But VFX is not just about spectacular CGI. There are many different techniques involved in creating a final movie shot.
Let's explore some of the most important types of VFX used in movies.
- CGI – Computer-Generated Imagery
CGI involves creating digital images and 3D elements using computers.
It can be used to create:
- Digital characters and creatures
- Vehicles and buildings
- Futuristic cities
- Digital environments
- Props and objects
- Entire imaginary worlds
CGI is commonly used when creating something physically would be difficult or impossible.
- Green Screen and Chroma Keying
Green screen allows filmmakers to replace the background behind an actor or object.
An actor may be filmed in front of a green background and later placed into a completely different environment.
It is widely used for:
- Fantasy locations
- Action sequences
- Space scenes
- Digital environments
- Stunt sequences
Proper lighting and compositing are essential to make the replacement look realistic.
- Rotoscopy
Rotoscopy involves creating detailed masks around people or objects in footage.
It is used when artists need to separate a subject from its background or isolate specific elements.
Rotoscopy is commonly required for:
- Background replacement
- Object removal
- Compositing
- Creating detailed mattes
A rotoscopy artist needs patience, precision and strong attention to detail.
- Matchmoving and Camera Tracking
When digital elements are added to live-action footage, they need to move correctly with the camera.
Matchmoving and camera tracking help artists recreate camera and object movement digitally.
This is important for integrating:
- CGI
- Digital environments
- Set extensions
- 3D objects
- Screen replacements
Without accurate tracking, digital elements can appear to float or move unnaturally.
- 3D Modelling
3D modelling is the process of creating digital objects and environments.
Artists can create:
- Characters
- Buildings
- Vehicles
- Creatures
- Props
- Digital environments
These models can then be textured, animated, lit and rendered for use in the final shot.
- Digital Environments and Set Extensions
Filmmakers don't always need to build an entire location physically.
A small set can be digitally extended to create a much larger environment such as a futuristic city, historical location or fantasy landscape.
This technique helps filmmakers achieve large-scale visuals without physically constructing everything seen on screen.
- Compositing
Compositing brings different visual elements together to create the final shot.
A compositor may combine:
- Live-action footage
- CGI
- Green-screen footage
- Digital backgrounds
- Smoke and fire
- Particles
- Shadows and reflections
The goal is to make all the elements look as though they were captured together.
Compositing requires a strong understanding of colour, light, perspective and visual continuity.
- FX and Simulation
How do movies create realistic fire, explosions, smoke, water and destruction?
These effects can be created using FX and simulation techniques.
FX artists can create:
- Fire
- Smoke
- Explosions
- Water
- Dust
- Debris
- Destruction
- Particles
These effects are designed to behave convincingly while supporting the creative requirements of the scene.
- Motion Capture
Motion Capture (MoCap) records the movement and performance of actors and can be used to animate digital characters.
It is commonly used for:
- Digital characters
- Creatures
- Human movement
- Games
- Virtual production
Animators can further refine captured performances to achieve the desired result.
- Digital Characters and Creatures
Movies often feature characters that are completely computer-generated.
These may include:
- Monsters
- Aliens
- Fantasy creatures
- Digital humans
- Digital animals
Creating these characters can involve modelling, texturing, rigging, animation, lighting, FX and compositing.
- Digital Doubles
A digital double is a computer-generated version of a real actor.
Digital doubles can be used for dangerous stunts, extreme environments, large-scale action sequences or scenes that would be difficult to film practically.
- Object Removal and Digital Cleanup
VFX is also used to remove unwanted elements from movie footage.
Artists may remove:
- Wires
- Equipment
- Crew members
- Signs
- Unwanted objects
- Temporary structures
The objective is to make the removal completely invisible in the final shot.
- Virtual Production
Virtual production combines live-action filmmaking with digital environments and real-time technologies.
Game engines and LED-based environments can allow filmmakers to work with digital locations while shooting.
It is creating new possibilities across filmmaking, VFX, animation and gaming.
How Different VFX Techniques Work Together
A single movie shot may use several VFX techniques at the same time.
For example, a scene featuring an actor in a futuristic city could involve:
Green Screen → Rotoscopy → Camera Tracking → 3D Modelling → Texturing → Lighting → FX → Compositing
The audience sees one final image, but behind it may be the work of several specialised VFX artists.
This is why VFX is a team-based profession, with roles such as 3D artists, compositors, rotoscopy artists, matchmove artists, FX artists, lighting artists and animators.
You don't need to master everything. Start by exploring different areas and gradually develop expertise in the specialisation that interests you most.
