Ramayana Part 1 Uses DNEG AI Lip Sync Tech, Explains Producer

Sony Pictures has globally released the English trailer for director Nitesh Tiwari's upcoming cinematic epic Ramayana: Part 1, providing international audiences with a preview of the scale and visual presentation. Beyond its grand aesthetics, the trailer highlighted a key technological feature designed to make the international dialogue sound natural.

Unlike traditional film dubbing—where an audio track in a new language is simply layered over the original video—the English release of Ramayana: Part 1 uses specialized software developed by visual effects studio DNEG. The AI-powered application digitally adjusts the mouth movements of the actors so their physical expressions align precisely with the spoken English lines.

Addressing the technology behind the adaptation, producer Namit Malhotra detailed the process during an interview with ET Now. Malhotra explained that the project combines real actor performances with digital tools to produce a natural visual output. He stressed that artificial intelligence did not generate the sequence from scratch; rather, the process began with authentic human acting before the digital modifications were applied.

According to Bollywood Hungama, this integration of artificial intelligence with original visual capture offers a refined alternative to conventional localization methods. The technology adjusts lip movements frame by frame, preserving the subtle facial expressions of the cast while adapting their dialogue for global markets.

As Ramayana: Part 1 prepares for its international debut, the studio's reliance on DNEG's AI-assisted sync technology reflects growing industry interest in advanced localization tech. The project seeks to establish a high technical standard for global cinematic releases originating from Indian cinema.
