What Are Virtual Actors?

Virtual actors are digital representations of human or non-human characters that perform roles in entertainment media. Unlike traditional actors, virtual actors are created through computer graphics, AI, and motion capture, with their actions and expressions driven by software algorithms. Over the years, virtual characters have been used in various forms—ranging from fully CGI (computer-generated imagery) characters to more advanced deepfake technology and digital twins of real actors.

While virtual actors have primarily been used as supporting characters in the past, the prospect of having them take on leading roles in major productions is rapidly becoming a reality. Virtual actors offer unique possibilities in storytelling and can be used to create characters that would otherwise be too costly, impossible, or even unethical to portray with human performers. With the advent of more advanced technologies, the boundaries of what virtual actors can achieve are expanding at an unprecedented rate.

Key Technologies Behind Virtual Actors

The rise of virtual actors is fueled by several key technologies, each playing a crucial role in creating lifelike digital performers. These innovations make it possible to simulate human-like behaviors, emotions, and interactions in ways that were once unimaginable.

Motion Capture and Performance Capture

Motion capture (MoCap) is a technology used to record human movements and transfer them onto digital models. This technology is essential in creating realistic virtual actors, as it allows animators to capture the subtlety of human gestures, facial expressions, and body language. Performance capture takes this a step further, recording not only movement but also the actor’s emotions and voice, allowing virtual characters to express feelings just as a human actor would. Popular examples of MoCap include Gollum in The Lord of the Rings and Thanos in Avengers: Infinity War.

Artificial Intelligence and Machine Learning

AI and machine learning algorithms are integral in making virtual actors more intelligent and autonomous. These technologies help create characters that can learn, adapt, and respond to different stimuli in a performance, making them more interactive and dynamic. AI can generate dialogue, determine emotional responses, and even simulate a character’s decision-making process based on pre-programmed behavior or learned data.

Voice Synthesis and Deep Learning

Voice synthesis technologies allow virtual actors to speak with human-like voices, thanks to advances in deep learning models. These systems can generate voices that sound realistic, adapt to different accents, and express a wide range of emotions. This technology is used in creating fully digital characters or enhancing the performances of human actors with voiceover work.

Real-Time Rendering and Virtual Reality (VR)

Real-time rendering allows virtual actors to interact in dynamic environments without delays in processing, creating an immersive experience for viewers. VR and AR technologies further enable audiences to experience virtual actors in interactive settings, such as live virtual concerts or immersive video games.

The Role of Virtual Actors in Modern Entertainment

Virtual actors have already begun to leave a mark in various entertainment mediums, and their presence is expected to grow as technology continues to advance.

Virtual Actors in Film and Television

In cinema and television, virtual actors are being used both in animated films and as digital characters within live-action productions. With advancements in CGI and AI, filmmakers can now integrate virtual characters seamlessly into live-action scenes. For example, the character of Thanos in the Avengers films was brought to life using CGI and motion capture, allowing a fully digital character to interact with real-world actors.

While virtual actors have mostly supported roles, some filmmakers are exploring the potential for digital characters to take center stage. Digital recreations of deceased actors or entirely synthetic characters are pushing the boundaries of what’s possible in storytelling.

Virtual Actors in Video Games

In the video game industry, virtual actors have become an integral part of creating engaging, immersive experiences. Video game characters are often modeled with motion capture and AI, allowing them to interact dynamically with players. From the complex characters in The Last of Us to interactive NPCs (non-playable characters) in open-world games like Red Dead Redemption 2, virtual actors are central to creating emotionally charged gaming experiences.

Virtual Performers in Music Videos and Concerts

Virtual performers are also making waves in music, with artists using holograms and digital avatars to perform on stage or appear in music videos. Virtual pop stars, like Hatsune Miku, have amassed huge fan bases and held live concerts, all while being completely computer-generated. This has opened up new possibilities for music videos, where virtual actors can interact with physical performers and enhance the overall narrative of the song.

Opportunities for Virtual Actors in the Entertainment Industry

The rise of virtual actors brings several opportunities to the entertainment industry, both creatively and economically.

Cost Efficiency and Production Time

One of the major advantages of virtual actors is their ability to save time and money in production. Since virtual characters can be controlled, animated, and rendered digitally, they reduce the need for on-location shooting, actor travel, and even the physical limitations of human performers. Moreover, virtual actors don’t require breaks, extensive wardrobe changes, or other logistical considerations that human actors might need, speeding up the overall production process.

Creative Freedom and Control

Virtual actors give directors and producers more creative freedom in character design, performance, and behavior. They can create characters that would be difficult, expensive, or impossible to portray with real human actors—such as alien beings, animals, or historical figures that have long passed. These digital characters can be designed to perform exactly as envisioned, with no limitations due to physical abilities or human emotions.

Global Reach and Customization

Virtual actors can also help in creating content that can be easily adapted to different markets. A virtual actor can be customized to speak various languages, feature different looks, or even alter their personality to better appeal to local audiences. This flexibility could significantly expand global reach and make content more accessible to diverse international markets.

Challenges and Limitations of Virtual Actors

Despite their potential, there are challenges that must be addressed before virtual actors can fully integrate into the entertainment industry.

Ethical and Legal Concerns

The use of virtual actors, especially those modeled after real, deceased performers, raises significant ethical questions. Issues such as the ownership of digital likenesses, the exploitation of deceased actors, and consent are important legal considerations. Additionally, virtual actors could potentially replace human performers, leading to job displacement within the industry.

Audience Acceptance and Emotional Connection

While virtual actors are becoming increasingly sophisticated, audiences still find it challenging to form emotional connections with digital characters. The “uncanny valley” effect, where characters look almost human but not quite right, can make virtual actors feel unsettling to viewers. Overcoming this barrier is a major challenge in gaining full acceptance for virtual actors in major roles.

Performance Limitations and Authenticity

Despite advancements, virtual actors still struggle to replicate the depth and nuance of human performances. While they can mimic gestures and expressions, conveying genuine human emotion remains a significant hurdle. Human actors bring authenticity to performances that virtual actors, for now, cannot entirely replicate.
