What is LipDub AI, and the best alternative

Korean and Spanish content alone captured 16% of all global Netflix viewing in the first half of 2024, according to Omdia. Non-English video is now a core part of what audiences watch, which is why tools that translate a performance without reshooting it have moved from novelty to production line. LipDub AI is one of them: a lip sync and dubbing platform built by the VFX studio MARZ for professional creators. The closest alternative when you also want a self-serve tool, a developer API, and a managed studio pipeline in one place is sync. labs, which lip syncs and dubs the video you already have across 95+ languages on sync-3, its most advanced model.

This page explains what LipDub AI does, its languages and pricing, and where sync. labs is the stronger fit, so you can pick the right tool for the job you are actually doing.

LipDub AI is MARZ’s production-grade lip sync and dubbing platform

LipDub AI is an AI lip sync and video translation platform from MARZ, an Oscar-nominated visual effects studio, launched in beta in February 2024. It re-syncs a speaker’s mouth to new or translated audio while keeping the original face, and it is aimed at professional production rather than casual use. Per its own site as of July 2026, it works across live-action, animated, and AI-generated video, holds accuracy on side profiles and extreme angles, and can lip sync multiple speakers in a single clip.

The platform is positioned at the high end. MARZ’s pitch is Hollywood-standard dubbing done in minutes instead of weeks, and its background is servicing film and television VFX, so the product reflects that lineage.

What LipDub AI does

LipDub AI covers the core visual-dubbing workflow: translate the audio, generate or clone a voice, and re-sync the mouth to match. Per its own site as of July 2026, it offers:

• Translation across 100+ languages. Auto-translation is built in for a set of languages, and you can upload your own audio in any language for the rest.
• A library of 5,000+ AI voices, filterable by language, accent, age, and gender, plus voice cloning and text-to-speech.
• Multi-speaker lip sync in one video, with accuracy held on side profiles and extreme angles.
• Selective dubbing, so you can replace only the lines you need instead of the whole track.
• Data ownership, with a stated policy that it does not train its models on your uploaded video.

Pricing is credit-based with a free trial that needs no credit card, plus custom enterprise plans and pay-as-you-scale API credits, per its site as of July 2026. In practice LipDub AI is sold as an enterprise and production tool first.

sync. labs is the best LipDub AI alternative when you want one platform end to end

sync. labs does the same core job, lip sync and dubbing on the video you already have, and it competes directly with LipDub AI on quality: it keeps the real face, performance, and the speaker’s own voice rather than generating a stand-in. Where it pulls ahead is reach. sync. labs is a self-serve app, a developer platform, and a managed production partner at once, so the same technology scales from a single clip to a feature.

sync-3 is the model underneath. It reads the whole scene, where the face sits, the lighting, who is speaking, before it adjusts the mouth, which is what holds it together on hard shots like side profiles, close-ups, low light, and multi-speaker frames, up to 4K at 60fps. A few things separate it from LipDub AI:

• One platform from self-serve to studio. Start free in the browser, wire it into your product through the API, or hand a finished master to sync. labs as a production partner for visual dubbing and dialogue replacement. LipDub AI is sold mainly as an enterprise product.
• A real developer surface. sync. labs runs through a REST API, an MCP server for Claude, Cursor, and ChatGPT, and a Batch API that takes up to 500 jobs in one request. It also has Adobe Premiere Pro, DaVinci Resolve, and ComfyUI integrations.
• Image-to-video. Start from a single photo and sync-3 builds a full talking performance, so you are not limited to footage you already shot.
• 95+ languages with the speaker’s own voice. Pick a target language and sync. labs handles translation, voice, and lip sync in one pass, with voice cloning that carries the original pitch, tone, and cadence across languages.

Average processing runs under 3 minutes at full HD, and you get 3 free videos a month with no credit card required.

sync. labs studios handles the theatrical end

LipDub AI comes from a VFX studio, and sync. labs meets that end of the market with sync. labs studios, a managed production partner for film and television. The studios team delivers visual dubbing and dialogue replacement (ADR) on finished masters, working in mastering formats like ProRes 4444 XQ and OpenEXR with HDR10 and ACES support. The difference is that the same models also run self-serve in the browser and through the API, so a project can start as a quick test and grow into a supervised theatrical job without switching tools.

Both are production-grade and both keep the real performer, so the choice is less about raw quality and more about how you want to work. LipDub AI is a focused enterprise dubbing product. sync. labs is broader: the same models available self-serve, through an API, or as a managed service.

How to pick between LipDub AI and sync. labs

Start with how you will actually use it. If you are an enterprise buyer who wants a single dedicated dubbing tool and a sales-led rollout, LipDub AI fits that shape. If you want to try it the same afternoon, build it into a product, or scale from one video to a batch of hundreds, sync. labs covers more of that range.
