Metabolismo — a journey of discovery
How I took a medical explainer format into real-time virtual sets, with real doctors shot on green screen.
The context
An episodic series on metabolic research and new treatment applications, produced with Art Meet for a medical client.
Each episode mixed studio segments, with guest doctors live on set, and interviews shot on location.
The challenge
Explaining a scientific subject clearly, with a TV-format look, without building physical sets.
The doctors had to move and speak naturally inside environments that only existed in 3D, and the shot had to stay believable even with the camera moving.
How I did it
3D environments
I designed and built the environments in Unreal Engine 5, planning them around the camera angles from the start.
Camera tracking
With Vive Mars and camera tracking, the real camera’s position and moves are passed to the virtual camera in real time.
Real-time compositing
In Aximmetry the green screen is replaced by the virtual set while shooting: the monitor already shows the final picture.
Studio and location
Guest doctors live in the studio, interviews on location: two different languages held together in the edit.
Edit and colour
Final edit and colour grading in DaVinci Resolve.
The outcome
A science format with the look of a TV production, shot in a green-screen studio instead of built sets.
The project helped the client win the Life Science Excellence Awards 2023.
