WORKSHOP DESCRIPTION

A major new development in AI-generated video is the emergence of “grey box” filmmaking.

This is where filmmakers shoot real human actors in a neutral environment. In theory, this could be a studio with plain grey walls – hence the phrase “grey box”. But in practice, almost any neutral environment will do. AI then takes the performances of the real human actors and transforms the world around them.

So you could film an actor in your living room in Berlin and the AI could put them on a crashing spaceship, a warship at the Battle of Trafalgar or in a Stone Age desert.

The crucial difference is that the performance comes from a human actor, while the world around them is created by AI.

Obviously, actors are creative artists, and their performances have a range of control, subtlety and emotional depth that conventional AI-generated video, where the performance itself is created by AI, simply cannot achieve.

Grey box filmmaking therefore offers a significant way forward. It promises more convincing and realistic dramatic performances while retaining one of the extraordinary opportunities created by AI filmmaking: the ability to put characters into almost any environment you can imagine.

Of course, the technology is still developing. Transformations aren’t always convincing, and preserving the details of a performance can be challenging. We’ll explore both what works and what doesn’t.

Grey box also changes some of the ethical questions around AI-generated video. A shoot is still required, human performers are still required and some level of human crew is still required, although production can be far less complex than traditional live-action filming.

In this practical two-day workshop, we’ll explore a series of grey box scenarios. Participants will film actors, then use AI to transform their performances into entirely different environments.

At the time of writing, the obvious technologies to explore are Seedance 2.5 and Higgsfield Genjutsu, which offers tools for transforming existing footage while preserving the underlying performance.

By the time the workshop takes place in early 2027, the leading technology may have changed. We’ll therefore use whatever software is most advanced and appropriate at the time.

ABOUT MARTIN PERCY

Martin Percy is a British director celebrated for his pioneering work in interactive cinema, virtual reality, and the creative use of artificial intelligence in film. A graduate of King’s College, Cambridge, Percy has built a career defined by experimentation with new forms of storytelling that actively involve the audience, merging narrative, technology, and participation.

His breakthrough came with Lifesaver (2012), an interactive crisis simulator that won a Grand Clio Award, a Webby Award, and received a BAFTA nomination. The project, which featured Daisy Ridley in her first professional role, established Percy as a leading figure in interactive film. He later expanded this format with Heart Class (2019), which won an Emmy in the United States, and CardiacCrash (2023), a Canadian project that won three Webby Awards and was nominated for the Canadian Screen Awards.

Percy has collaborated with some of the most respected institutions in the world, including the Tate Modern, the British Film Institute, the National Theatre, and the Asian Art Museum of San Francisco. His projects have often brought together acclaimed actors such as Sir Ian McKellen, Sir Derek Jacobi, and Daisy Ridley, combining high-profile talent with cutting-edge interactive design. His VR project Virry VR (2017), filmed at Lewa Wildlife Conservancy in Kenya, received both BAFTA and Webby recognition and reinforced his reputation as a leading innovator in immersive media.

In recent years, Percy has increasingly integrated artificial intelligence into his practice, creating works that adapt to the user’s emotions, decisions, and interactions. Projects such as AI Basics: Thrills or Chills (2023) and the Adaptive-Media Interview Coach exemplify his commitment to exploring how AI can reshape creative expression and audience engagement. His TEDx talk, How to Save Lives with Interactive Film, highlighted his dedication to using new technologies not just for storytelling, but also for education and social impact.
Throughout his career, Martin Percy has been recognised with a BAFTA, an Emmy, a Grand Clio, and more than a dozen Webby Awards. His work stands at the intersection of creativity and innovation, continually pushing the boundaries of how stories can be told and experienced.
