CGI and VFX are two popular technical terms in the filmmaking industry. Understanding the difference between CGI and VFX can be tricky. However, for creating stunning visuals, both terms are equally important. Visual effects include all the methods used to change and improve movie visuals after filming is done. This covers things like computer generated images, combining different images or practical effects like real explosions or stunts. CGI is just one part of VFX and is specifically about creating images using computer software.
In this article we guided you about CGI vs VFX, how they’re used in modern filmmaking, and the key differences between the two. By the end, you will know when to use CGI vs VFX and how they work together to bring stories to life.
What is CGI?
Computer generated imagery means creation of digital content by using computer software. CGI created different digital works like illustrations, animations, and digital images. Anything we create on computer platform digitally is called CGI. Adobe After Effects and Maya are the computer software that helps to create CGI digital work.
3D modeling, rigging, animation, shading, texturing, lighting, and rendering are the core components of CGI.
The Role of CGI in Modern Filmmaking: Benefits
Before the advancement of animation industry filmmakers were limited to traditional animation. But now times have changed and entire world exists inside the computer. Here are some key benefits and applications of CGI:
Benefits of Computer Generated Imagery
- CGI enhances the visual quality of the characters in the movie. It allows filmmakers to show audiences things they have never seen before.
- It is applicable across different fields including AR and VR.
- Also enhances brand credibility by providing better visual experience.
- CGI allows filmmakers to create cost effective digital sets or props rather than creating physical ones which are more expensive.
What is VFX?
VFX stands for visual effects. Visual effects create scenes that are impossible to generate in the physical mode. This includes everything from adding explosions to removing wires used in stunts. Many industries like gaming, advertisements, and the film industry, now use VFX. VFX includes CGI but also covers many other techniques like compositing, matte painting, and practical effects enhanced in post production.
Techniques of VFX in Enhancing Storytelling
VFX makes the impossible seem possible on screen. Its primary goal is to enhance storytelling without calling attention to itself.
Techniques in VFX
Rotoscoping
Rotoscoping is fundamental technique in visual effects that involves tracing over live action footage frame by frame to create mask. This technique is mostly used to replace or remove the background. Also ensure seamless integration of CGI with live action footage.
Green Screen
Green screen techniques are aka chroma keying. This technique involves filming subjects in front of green color background and then replacing that background with different images or video during post production.
Motion Tracking
Motion tracking is technique used in visual effects to analyze and replicate the movement of objects or cameras in live action footage. This data is then used to integrate computer generated imagery seamlessly into the scene.
Composting
Compositing in VFX is process of combining visual elements from multiple sources into single and cohesive scene.
CGI vs VFX: What’s the Difference
Now that we understand about CGI vs VFX are individually and let’s clarify the main differences:
| Differentiate | Computer Generated Imagery (CGI) | Visual Effects (VFX) |
| Meaning | Creating 2D images into 3D complex entirely with the help of computer software is called CGI. | Blend of digital elements including CGI with live action footage to create effects that are impossible to achieve during filmmaking is called VFX. |
| Techniques | 3D modeling, rigging, animation, shading, texturing, lighting, and rendering are the core components of CGI. | Rotoscoping, green screen, motion tracking, composting are the main techniques of VFX. |
| Applications | Animated movies, video games, architectural visualizations, and product designs include CGI where entire visual is generated digitally. | Adding live action footage with visual effects like fire explosions, weather phenomena, and creating safe stunts in filmmaking that are impossible without VFX. |
| Tools and Software | Unreal Engine, Blender, Maya, Redshift, Mari software used in CGI. | Mocha Pro, Fusion, Unreal Engine, Nuke, and Houdini software used by VFX artists for seamless integration. |
| Workflow | CGI work process happens during the early and ongoing stages of project. It involves creating and improving individual elements that can either stand on their own or be combined with other parts later. | A post production focused process requires collaboration between CGI artists, cinematographers, and VFX supervisors to integrate and enhance scenes seamlessly. |
| Cost | Creating fully digital CGI environment results in high cost due to computational requirements for modeling, texturing, and rendering. | Cost varies according to the project. Simple enhancements are made at low cost and heavy projects are more expensive in which live action footage and CGI includes. |
When to Use CGI vs VFX: Choosing the Right Approach for Your Project Needs
VFX and CGI play very important roles in bringing ideas to life in digital content creation landscape. Choosing right approach depends on project’s requirements, budget, and artistic vision of creativity.
When to Use VFX Over CGI?
- When VFX artists work with live action footage.
- For creating realistic effects in films or commercials.
- When you need to enhance practical effects rather than create everything digitally.
When to Use CGI Over VFX?
