Imagine sitting in a cinema in 1895 watching what appears to be a real beheading on screen The audience was stunned, not because the film was new to them, but because nobody had ever seen anything like this on it before.
That short film was "The Execution of Mary, Queen of Scots". It was the first visual effect ever recorded in cinema history. CGI came nearly a century later and took things a step ahead. It did not just manipulate what the camera captures. It removed the camera from the process entirely.
One craft learned to bend reality The other realised it did not need reality to begin with That is where the difference between CGI and VFX actually starts
What Is CGI?
CGI stands for Computer-Generated Imagery The entire visual is constructed inside software, with no physical production at any stage
A 3D artist models the subject, builds the environment, sets the lighting, applies textures, and renders the final image entirely on a computer. The product was never placed on a surface. The landscape was never visited. Nothing was filmed because nothing needed to be.
For brands, this matters practically. Build a 3D asset once and use it across every format, market, and season without booking a studio each time The initial build is the investment Everything after that is leverage
What Is VFX?
VFX stands for Visual Effects. It always starts with something a camera actually recorded
An actor performs A car drives A product is held Then post-production begins, backgrounds replaced, environments built, digital elements composited into the footage until the final frame looks entirely different from what was originally shot
VFX does not create from scratch It takes something real and transforms it into something that could not exist without digital intervention The camera is the starting point, not an optional tool
What Is VFX and CGI When Used
Together?
The two are not in competition CGI is a tool VFX is the discipline that uses it
CGI sits inside the VFX pipeline, the way colour grading sits inside post-production. One is a specific technique, the other is the entire workflow built around it.
A real actor inside a fully digital city uses both The actor is live footage The city is CGI The process of making them coexist convincingly is VFX Neither term replaces the other, and on most serious productions, both are present in the same frame

Modeling and render time
The VFX pipeline runs across three phases, and problems in any one of them compound in the next.
Pre-production is where the VFX team breaks down every shot that needs digital work, builds rough previsualisations of complex sequences, and locks the scope before filming begins What gets decided here determines whether the budget holds throughout the entire production Skipping this phase is one of the most common reasons VFX projects run over time and over budget
Production puts a VFX supervisor on set to capture lighting references, lens data, and camera movement These details are what allow digital elements to integrate convincingly with the footage in post Without them, compositing becomes a guessing game that costs significant time and money to resolve
Post-production is where compositing, CGI integration, simulation, tracking, and rendering all happen. The quality of this phase is a direct result of how well the two
phases before it were managed. No amount of post-production skill fully compensates for data that was never captured on set.
What VFX and CGI Look Like in Advertising Today
Nike's "The Last Game" built a five-minute film featuring Ronaldo, Neymar, and Rooney without a single frame of live footage. Every player, every stadium, every moment is constructed entirely in software.
Samsung took the opposite approach with "Ostrich," filming a real bird on location and compositing the flight sequences in post to show something that could never be captured on set
Two completely different production approaches Both deliver something that could not exist any other way
Today, VFX and CGI in advertising are not special effects They are the primary production method for any campaign that needs to show the impossible
VFX or CGI: Which One Does Your Project Need?
The answer depends entirely on what you are starting with
If your project begins with real footage, real people, or a real location, VFX is the right approach. It takes what the camera captured and builds it into something that could not have been filmed. If your project begins with nothing, no location, no shoot, no physical product to photograph, CGI builds the entire visual from inside a computer.
Most serious campaigns use both. Film what makes practical sense to film, and build everything else digitally The brands getting the strongest results are the ones who make this decision at the brief stage, not after production has already started in the wrong
direction.
Why India's VFX and CGI Industry Looks
Different Now
India's animation and VFX industry is projected to reach USD 2.2 billion by 2026, driven by OTT growth, gaming demand, and international productions increasingly routing work through Indian studios.
The broader video production market in India was valued at USD 3,094 million in 2024 and is projected to reach USD 9,815 million by 2033 at a CAGR of 13.81 percent.
CGI video production in India is a growing share of that number, and the reason international briefs are moving here is creative capability, not just competitive cost Indian studios are being selected on the strength of their work, which is a meaningfully different position than where the industry stood five years ago
How to Choose a VFX and CGI Agency in India
The brief is the first test An agency that asks the right questions before opening any software is already ahead of one that leads with a quote and a software list
VFX work needs someone who understands production as much as post. CGI work needs an art director who understands brand as much as rendering. Both require the same foundation: creative thinking and technical execution, having the same conversation from day one, not patched together after the first review comes back flat.
A creative agency in India that operates that way is worth finding before you need them, not after your first deliverable misses the mark
