What is video style transfer?

‍

Video style transfer is a process that captures the visual characteristics from a source image or video and precisely applies those elements to different footage, creating a transformed visual output that maintains the original content but displays the new style.

‍

Style transfer might seem like a niche topic and a very technical term from the get-go. However, behind this seemingly technical concept lies something incredibly powerful with a much larger impact on the industry. Creative industry professionals have been captivated by this AI video tool for years, treating it almost like a holy grail. 

‍

This immediately raises the question: what is a style? Here's where complexities begin. 

‍

Does a style represent an art movement? Is it a collection of graphical qualities? For certain pieces, details like glitches or errors might be unwanted byproducts of the creation process, whereas in other cases, they form essential components of the style itself. An oversaturated palette might be a color grading mistake on one piece and an intentional feature on another.

‍

Style also encompasses themes, moods and other intangible concepts. When examining art movements and elements like symbolism, you'll discover paintings or content attributed to a movement through atmosphere, tone, and topics covered—qualities that prove much more difficult to define precisely. 

‍

The most practical way to think about style identifies it as the graphical qualities that define a specific creative method applied across multiple pieces, such as the "Van Gogh style," or more formally, Van Gogh's post-impressionism as defined by certain brush strokes, shapes and color palettes.

‍

The idea behind video stylization is to take an image—let's say a photo of a landscape—and apply Van Gogh's style to it.

The primary value stems from the fact that creating authentic Van Gogh-like artwork requires considerable skill and training. Video style transfer enables someone without extensive artistic training or time to create visually compelling stylized content.

The tech behind video stylization

‍

The technology behind video style transfer is sophisticated yet elegant. 

‍

At its core, the process separates "what" is in an image from "how" it's presented, then recombines these elements in new ways. 

‍

Modern AI video tools identify the content in your reference image, analyze artistic qualities from a reference style, and create a new image that fuses these elements together. 

‍

For videos, the model maintains consistency across frames to prevent the style from flickering as objects move—a key requirement for professional video stylization applications.

‍

The field of video style transfer models has evolved through several groundbreaking research advances. 

‍

In 2015, Gatys and colleagues published "A Neural Algorithm of Artistic Style," discovering that neural networks could separate and recombine content and style from different images. 

‍

The critical problem of temporal consistency in video was addressed in 2016 by Ruder and team in "Artistic Style Transfer for Videos," which used optical flow techniques to prevent flickering artifacts. 

‍

More recently, Rombach's team introduced latent diffusion models in 2022, dramatically improving quality while reducing computational requirements for video to video transformation.

‍

Where Video Style Transfer Matters Most

‍

The true game-changer emerges when applying style transfer to moving images. Traditionally, creators produce stylized content at tremendous expense and effort. 

‍

Creating anime or 2D animation typically requires artists to draw every frame individually.

‍

Consider the Van Gogh-inspired film "Loving Vincent," where artists painted each frame as an individual oil painting.

‍

The economics of video stylization production are significant. 

‍

Industry estimates suggest that traditional 2D animation can cost anywhere from $5,000 to $50,000 per minute to produce, depending on quality, complexity, and production location. 

‍

In 2D or 3D animation, creating stylized content demands significant time and financial investment because artists must perform much of the process manually.

‍

In 3D animation, creating a Van Gogh-inspired scene requires artists to manually paint every asset—every object and character—with 3D brushes. 

‍

This means artists must craft each chair, table, leaf, or star to match the target aesthetic, making it an expensive endeavor. Video style AI tools promise to dramatically reduce these costs.

The Evolution and Historical Context of Video Style Transfer

‍

The industry has long used adjacent techniques like rotoscoping, where artists film live-action sequences and paint over them. 

‍

Video style transfer aims to simplify this by enabling creators to film a scene and convert it into any animated style without drawing each frame. 

‍

This approach has a rich history in the industry; Disney's Cinderella captured fluid dance movements by filming actors and painting over the frames.

‍

"Loving Vincent" (2017) exemplifies the extraordinary effort traditionally required for stylized content. The world's first fully painted feature film employed approximately 125 artists who created around 65,000 individual oil paintings in Van Gogh's distinctive style, taking about seven years from concept to completion with a budget estimated at $5.5-6 million.

‍

Ralph Bakshi's animated "The Lord of the Rings" (1978) pioneered extensive use of rotoscoping for a feature film, where animators traced over footage frame by frame to create a distinctive fantasy aesthetic. Richard Linklater's "A Scanner Darkly" (2006) used digital rotoscoping with proprietary software called "Rotoshop" to transform live-action footage into a surreal animated style, with teams of artists digitally painting over each frame.

‍

Video stylization could automate much of this process. 

‍

The first meaningful step toward practical application came with EbSynth by the Secret Weapons team, which used texture synthesis to allow artists to draw over specific keyframes rather than every frame. 

‍

The next iteration leveraged diffusion models, first with Disco Diffusion and then Stable Diffusion, giving birth to video to video software like Warpfusion (developed by Aleksandr Spirin, cofounder and CTO of Mago).

‍

Applications and Industry Impact of AI Video Tools

‍

Various projects now explore video style transfer as an AI rendering solution for 3D animation. Companies like Mago and RunwayML are developing video to video solutions that transform live-action films into anime or create moving paintings.

‍

These video stylization technologies open up numerous production possibilities by using deep learning, computer vision and pre-trained transfer models. 

‍

Studios could use the AI video tools as a universal renderer, taking inputs from multiple sources—motion capture, 3D animation, and live action—and blending them into a cohesively stylized world. 

‍

Filmmakers might leverage techniques close to virtual production to shoot the base material IRL and later transform it with video style transfer according to the artistic direction of the show.

‍

The technology is evolving rapidly, and by 2025 we will likely see productions that use video style AI as a core component, particularly in advertising and social media initially, before expanding to become a standard rendering solution for animation studios.

‍

The economic impact could be transformative. 

‍

By automating many of the labor-intensive aspects of stylization, video to video technology has the potential to significantly reduce production costs and timelines for stylized content. 

‍

For independent creators and smaller studios especially, this could democratize access to visual styles and techniques that were previously only feasible for well-funded productions.

‍

More Than Just a Filter

‍

People often mistake video style transfer for a simple filter. 

‍

However, unlike filters that provide predefined results, video style AI can create virtually anything. 

‍

You can transform any video into any style or aesthetic you desire. Imagine combining this with video transformation; you could turn a chair into a spaceship rendered in the style of an impressionist painting based on a reference image, computer vision and a style reference.

‍

One of the core advantages of video stylization comes from its seamless integration with existing artistic workflows. 

‍

Artists can film scenes and use concept art to transform them into the final look, correcting frames or focusing on complex scenes like anime fight sequences. 

‍

This makes video style transfer one of the least disruptive AI approaches in production—a technology that empowers rather than replaces artists.

‍

While video stylization might appear niche, its potential lies in unleashing an unlimited variety of colors, shapes, styles, and aesthetics. 

‍

Previously, resource limitations prevented solo content creators or small teams from achieving professional-level styles or working in genres once reserved for major studios.

‍

Ultimately, video style transfer empowers the entire industry.

‍

It will likely trigger an explosion of creativity, where future productions might not resemble real life but instead showcase diverse and imaginative visuals. The limits of reality no longer constrain our creative expression.
