What is the Difference Between CGI and VFX With Examples?

Have you ever wondered how cult movies like Jurassic Park and Avatar could showcase a parallel world with convincing, breathtaking visuals, or how superheroes battle in visually stunning landscapes, as seen in Avengers Endgame? The secret to these out-of-the-world visual and extraordinary cinematic experiences lies in CGI (Computer-Generated Imagery) and VFX (Visual Effects). CGI and VFX are two of the most powerful techniques that can bring even wild imagination to life.

Many beginners confuse them, and knowing the difference can help you choose the right career path.

In this blog, we will break down CGI and VFX in simple terms, explore real-world examples, and guide you on how to get started in the entertainment industry.

What is CGI?

Before coming to the definition of CGI, let us first decipher why we need CGI in the first place! Imagine trying to film Jurassic Park in real-time, with the ferocious dinosaurs (only if they weren’t extinct today), sounds impossible right?

CGI, or Computer-Generated Imagery, solves this problem by creating fully digital visuals using specialized software. CGI is used for animation as well, applicable in both 2D and 3D spaces. It provides the liberty to filmmakers, game developers, and animators to build an entirely new world, though limited to screens, characters, and effects from scratch without real-world limitations.

Prior to CGI, filmmakers relied on physical models, prosthetics, and stop-motion animation, which were time-consuming, expensive, and limited in realism.

Real-life Example of CGI

James Cameron’s Avatar set new standards for CGI by creating an entirely digital world, Pandora. The Na’vi characters were not just animated, they were motion-captured CGI, blending real performances with digital artistry.

What is VFX?

Ever watched Doctor Strange open a portal, seen entire cities collapse in action films, or wondered how Dobby from Harry Potter interacts with real actors?

The challenge with filmmaking is that not everything can (or should) be filmed in real life. Creating massive explosions, magical spells, or mythical creatures practically would be dangerous, expensive, and sometimes just impossible. This is where VFX comes in!

Unlike CGI, which creates fully digital elements, VFX combines CGI with real-world footage to make illusions feel natural. Moreover, CGI comes under the umbrella of VFX. To simplify it, you may think VFX as a tool that allows the enhancement of live-action scenes with computer-generated elements, so you believe what you’re seeing is real!

VFX Application

The practical implication of VFX can be witnessed through some of the most mind-blowing scenes in movies and TV shows. Some of the most common application of VFX can be witnessed in:

• Scenes pertaining to explosions, such as collapsing cities, and massive crashes.
• VFX adds background as actors perform in front of a green screen.
• With the help of VFX, actors can interact with CGI creatures, for example, Dobby in Harry Potter.
