Allu Arjun's upcoming film ‘Raaka’ has entered the Guinness World Records for the “Most People Motion-Captured in Real-Time”, after 37 performers were motion-captured simultaneously during a single session.
The achievement is notable not just for the record itself, but for the scale of the technology used to make it possible. The performers ranged in age from four to 70, meaning the system had to track people with different physicalities while they moved and performed together in the same space.
Why capturing 37 performers was challenging
Motion capture, or mocap, records the movements of real performers and converts that data into digital animation. The technology is commonly used to create CGI characters, with systems capable of tracking body movements and, depending on the setup, facial expressions.
For ‘Raaka’, the challenge was multiplied several times. Instead of capturing performers individually, the team had to track all 37 people at once and preserve each person's movements separately.
Mocap technical director Brian Rausch explained that the process involves much more than simply recording a performance.
"People think you hit a button and you get a bunch of animation out of it and it's just usable. It's not."
The complexity increased further because several digital characters will be interacting within the same sequences.
"There are like so many characters and a lot of action in it. There are a lot of interactions with all these mocap characters," director of photography GK Vishnu said.
92 cameras and a custom-built system
According to director Atlee, India had existing motion-capture facilities, but they lacked the larger capture volume needed for the project. That led the team to build its own setup.
"We have mocap stations in India but we didn't have bigger volume. Then I called my producer Kalanithi Maran sir. He said, yes, buy it. Let's have our own system. We brought all the equipments from LA. We established our own base," Atlee said.
The team eventually created a motion-capture pipeline specifically for the film. For the Guinness attempt, 92 optical motion-capture cameras were used, alongside calibration, networking and synchronisation systems. The setup also featured real-time Unreal visualisation, witness cameras and facial capture.
The 37 performers were captured simultaneously inside the same capture volume rather than being recorded separately and combined later.
Allu Arjun credits the team
Allu Arjun said the achievement was about taking an ambitious idea through to execution.
"A lot of people have ideas and have a vision, but to get to execute it at the finest quality is quite something."
He credited Atlee and the wider team, while also thanking Sun Pictures for backing the project.
Atlee added, "I hope I will make everyone proud of our country for sure."
What is known about ‘Raaka’
Allu Arjun is reportedly playing four roles in the film—a grandfather, a father and two sons. There is also speculation that the story could involve two parallel universes, although the makers have not officially confirmed these details.
The sci-fi action drama also stars Deepika Padukone, Rashmika Mandanna, Janhvi Kapoor and Mrunal Thakur in pivotal roles. Produced by Sun Pictures, the film marks Allu Arjun's first collaboration with Atlee.
