LipDub AI

LipDub AI localizes video into other languages and re-syncs the speaker's lips to the new audio, so dubbed footage no longer looks dubbed. It came out of the Toronto visual-effects studio MARZ, was unveiled in August 2023, and now says it has localized more than 10,000 hours of video.

About

Dubbing has always had a visible seam: the voice changes language and the mouth does not follow. LipDub AI uses deep neural networks to redraw an on-screen performer's lip movements to match a dubbed audio track, at what its makers pitch as broadcast and Hollywood quality rather than the smeared results of consumer lip-sync tools. It is the second AI product out of MARZ — Monsters Aliens Robots Zombies — the Toronto visual-effects studio founded in 2018 that did work on Marvel and Netflix series before turning its internal tooling into software; Vanity AI was the first. MARZ announced LipDub AI in August 2023 and released a beta for professional creators in February 2024, claiming it could turn a minute of footage into any language in under twenty minutes of compute. The product now sells itself directly to brands, agencies and educators: "Localize any video you've already made in 80+ languages, with broadcast-quality lip sync. From a 30-second ad to a multi-hour course," with voice cloning, dubbing and a developer API. Matt Panousis, MARZ's co-founder and chief operating officer, is co-founder and COO here too.

Backers

No standalone funding round has been announced; LipDub AI was developed and released by MARZ rather than raised for separately.

Where did LipDub AI come from?

It is the second AI product from MARZ, the Toronto visual-effects studio founded in 2018 by a team including Matt Panousis. MARZ unveiled it in August 2023 and released a professional beta in February 2024.

Who uses it?

Brands, agencies and educators — the company cites more than 1,000 of them across 40-plus countries, with WPP and Washington Square Films among the named customers on its site.
