overview

What is LipDub AI?

LipDub AI is an AI-powered video localization tool developed by MARZ (Monsters Aliens Robots Zombies) that enables professional video production teams to achieve high-fidelity, photorealistic lip-sync. It specializes in automatically dubbing and synchronizing lip movements in videos with new audio, preserving original facial expressions and quality across natural movement. Unveiled in August 2023 as MARZ's second AI for VFX product, LipDub AI entered a private beta phase in February 2024, targeting professional content producers. The platform is designed to modify only the mouth region of a speaker in a video, ensuring that original facial expressions, camera movement, lighting, and body language remain consistent. This capability supports multilingual dubbing, dialogue replacement, and personalization for various content types, including cinematic productions and broadcast-quality media.
