The BBC’s Tokyo 2020 (yes, I know it’s 2021, but they kept the name) studio looked pretty real to casual observers watching the coverage of the recently-concluded Olympics. You’d turn on your TV and you’d think they were actually in a fancy rooftop studio in Tokyo providing their thoughts and commentary. But no.
The BBC Sport team was actually in a comfy green-screen studio in Salford near Manchester, England. The on-screen magic was brought to life thanks to Unreal Engine. Some very clever software mapped the positions of the cameras in the studio, keyed out the presenters from the green background and then composited it with the virtual set in real-time.
