How Are VFX Shots Made? A Step-by-Step Look at the VFX Production Process

A VFX shot may look simple on screen, but what appears to be a few seconds of footage can involve multiple artists, departments, reviews and technical processes.

A character walking through a futuristic city, a building collapsing, or even a simple object disappearing from a scene may require several stages of VFX production before the final frame is ready.

So, how are VFX shots made?

The answer lies in a structured but flexible VFX pipeline that takes a shot from creative brief to final delivery. The exact workflow changes depending on the project and shot, but the basic process remains connected.

What Is a VFX Shot?

A VFX shot is a shot that has been digitally created, altered, enhanced or combined with other visual elements.

Not every VFX shot is a large CG sequence.

It could involve:

• Removing an unwanted object
• Replacing a background
• Extending a physical set
• Adding a CG character
• Creating fire, smoke or destruction
• Combining live-action footage with digital environments
• Cleaning wires, rigs or other production elements

This is why VFX is often both visible and invisible. The audience may notice a digital creature, but they may never notice the hundreds of small changes made to a supposedly ordinary shot.

The VFX Production Process at a Glance

A typical VFX workflow can look something like this:

Brief → Planning → Plate Preparation → Tracking/Matchmove → Rotoscopy → Paint/Cleanup → CG & FX → Lighting → Rendering → Compositing → Review → Final Delivery

Not every shot requires every stage. A simple cleanup shot may need only roto, paint and compositing, while a complex CG sequence may involve several specialist departments.

Step 1: Understanding the Brief

Before artists start working, the team needs to understand what the shot is supposed to achieve.

The brief may include storyboards, concept art, references, camera information and technical requirements.

The VFX team identifies what needs to be created, removed, replaced or enhanced and determines how the shot can be approached.

This planning stage is important because problems that are not considered early can create additional work later.

Step 2: Capturing and Preparing the Plate

The original live-action footage used for VFX work is commonly called the plate.

The quality and information contained in the plate can significantly affect the work that follows.

Depending on the shot, production may capture camera and lens information, tracking markers, clean plates, reference photography, lighting references and other useful data.

The VFX team then prepares the footage for downstream work.

Step 3: Tracking and Matchmove

Suppose a filmmaker wants to place a CG object inside a moving shot.

The digital object needs to move correctly with the camera and perspective of the original footage.

This is where tracking and matchmove come in.

Artists analyze movement in the footage and recreate relevant camera or object movement in a digital environment. This gives later departments the foundation they need to position CG elements accurately.

Without accurate tracking, even a well-made CG asset can look like it is simply floating over the footage.

Step 4: Rotoscopy and Paint

Rotoscopy, or roto, involves creating mattes that isolate people or objects within footage.

Paint and cleanup work can then be used to remove unwanted elements, repair parts of a frame, remove wires or rigs, and prepare footage for compositing.

These tasks may not be visually dramatic, but they are critical.

A single unwanted edge, wire or background element can make a finished VFX shot feel wrong.

Step 5: Creating CG Elements

If the shot requires a digital object, character or environment, the CG pipeline begins.

Depending on the requirement, artists may work on:

• 3D modelling
• Texturing
• Look development
• Asset preparation

A simple CG object may require relatively little work, while a digital creature or detailed environment can involve several specialised artists.

Not every VFX shot needs a newly created CG asset.

Step 6: Animation and Simulation

Some CG elements need movement.

Animation controls the movement or performance of a digital character, object or vehicle.

Simulation, on the other hand, is commonly used to reproduce physical or environmental behaviour such as smoke, fire, water, dust, debris or destruction.

The two processes can work together. A digital creature may be animated while smoke and debris around it are simulated separately.

Step 7: Lighting and Rendering

A CG element has to look as though it belongs in the original scene.

Lighting artists recreate the lighting conditions of the live-action environment, working with elements such as shadows, reflections, materials and highlights.

The CG scene is then rendered into images that can be taken into compositing.

Technically accurate CG can still look unrealistic if its lighting, shadows or reflections do not match the original footage.

Step 8: Compositing — Bringing the Shot Together

This is where many elements finally become one image.

A compositor may combine the live-action plate with:

• CG elements
• Roto mattes
• Paint work
• Effects
• Shadows
• Reflections
• Atmospheric elements
• Colour adjustments

The goal is integration.

The CG should not look like something placed on top of the footage. It should appear to belong inside the same environment.

Step 9: Review and Revisions

A VFX shot rarely becomes final in one pass.

Artists and supervisors review the work, identify issues and create new versions based on feedback.

Depending on the production, feedback may come from the VFX supervisor, director, producer, client or other stakeholders.

Iterations are a normal part of professional VFX production.

Step 10: Final Delivery

Once the shot is approved, the final version is rendered and delivered according to the production’s technical specifications.

These can include resolution, frame rate, colour requirements and file format.

The approved VFX shot is then incorporated into the final edit or finishing workflow.

A Simple Example: Creating a Futuristic City

Imagine a filmmaker shoots an actor on a real street but wants the final scene to show a futuristic city.

The original footage becomes the plate.

The VFX team can then track the camera, isolate the actor through roto, create or prepare the digital environment, light the CG elements to match the scene, render the environment and composite everything together.

After reviews and revisions, the final shot may look as though the actor was actually filmed inside that futuristic city.

What the audience sees is one image.

Behind it is a coordinated VFX pipeline involving several stages and artists.

Why Does a VFX Shot Take So Much Work?

The complexity of a shot depends on factors such as the number of elements, camera movement, actor interaction, simulation requirements, level of detail and number of revisions.

A two-second shot can sometimes require more work than a longer shot if it contains complex interactions or detailed visual effects.

This is why professional VFX production cannot be measured simply by screen time.

The People Behind the VFX Process

VFX is a collaborative discipline.

Depending on the production, the team may include a VFX supervisor, producer, CG supervisor, matchmove artists, roto and paint artists, modelers, texture and look-development artists, animators, FX artists, lighting artists, compositors and quality-control teams.

Not every project has every role as a separate department. Smaller productions may combine responsibilities, while large productions can divide them across specialised teams.

Studios such as Digikore VFX bring these specialised capabilities together to support different types of visual effects production.

Final Thoughts

The next time a VFX shot looks effortless, remember that the simplicity on screen may be the result of a highly structured process behind it.

From the initial brief and plate preparation to tracking, roto, CG, lighting, compositing and final review, every stage contributes to the finished image.

That is how VFX shots are made: not through one single effect, but through many connected creative and technical processes working toward one believable frame.
