Overview

The API accepts MP4 video and WAV or MP3 audio by public URL or direct upload. Active-speaker detection runs automatically and can be disabled per request. CHAMELAION says its model preserves speaker identity, speaking style, and expressions while matching lip movements to new audio.

Those capabilities align with video dubbing and translation, AI avatars, UGC and creative ads, and dialogue replacement or personalization. The company describes support for audio and video translation into 30 languages; the supported-languages count is 28, so confirm coverage for the languages a project needs.

The maker says users retain full ownership of generated videos and that content is processed for translation and dubbing. Its servers are hosted in Europe, and CHAMELAION says its subcontractors comply with GDPR or have signed Data Processing Agreements. API requests use a Bearer token or x-api-key header, except at the health endpoint.

Key features

The generation endpoints allow 60 requests per minute, while maximum concurrent jobs depend on plan. The rate limit is clear, but concurrency needs to be considered against the chosen tier.
Developer tooling: SDKs cover Python 3.8+ and TypeScript/Node.js 18+, making the API a natural fit for teams working in either environment. Other stacks can use the API, but these are the SDKs named by the documentation.
Footage constraints: Profile views can work when the mouth remains sufficiently visible. Extreme close-ups, side views above 90 degrees, and cropped mouths are difficult scenarios, so source framing can rule out otherwise suitable clips.
Voice cloning and watermarking: Voice cloning is supported and watermark-free output is available. Those capabilities help with workflows that need generated speech and clean output, though plan quotas still bound the amount of translation.

Pricing

CHAMELAION uses a freemium model, with a free trial also offered. The token allowance is not interchangeable with a large volume of finished video: several paid tiers provide 60,000 tokens, equated to five minutes of video translation or lip sync.

Starter — free: 24,000 tokens, equivalent to two minutes of video translation plus lip sync, with a watermark and no credit card required. It is useful for a small evaluation, but the short allowance and watermark limit its fit for regular client delivery.
Basic — 4.00 EUR per year, billed Yearly: 60,000 tokens, equivalent to five minutes, videos of any size and length, and no watermark. The low annual price removes the watermark and stated video length cap, but the five-minute translation allowance remains small for frequent production.
Bronze — 20.00 EUR per year, billed Yearly: 60,000 tokens, five minutes of video translation, a stated 60-minute video length, and extra tokens available. It adds the option to buy more tokens, but the five-minute included translation allowance is unchanged.
Silver — 96.00 EUR per year, billed Yearly: 60,000 tokens, five minutes of translation, three seats, glossary, priority support, and SRT upload. It suits a small team that needs collaboration and those workflow features; the quota is still modest.
Gold — 500.00 EUR per month, billed Monthly: 60,000 tokens, five minutes of video translation or lip sync, five seats, glossary, priority support, and SRT upload. It expands the team allowance over Silver but retains the same stated token and minute allocation, so its higher price is best justified by the seats and included workflow support.
Enterprise — custom pricing: Individual pricing and tokens, premium support, and a custom contract suit organizations that need a tailored arrangement rather than a fixed allowance.

Check plan-specific concurrency alongside token needs before building a production pipeline: requests are capped at 60 per minute, and the maximum simultaneous jobs varies by plan.

Platforms

CHAMELAION supports API and web access. The API fits integration into software workflows; the web option gives users a route that does not require building around an API. The named SDKs are for Python 3.8+ and TypeScript/Node.js 18+.

Who it's for

This is best suited to developers and teams creating dubbing, translation, avatar, ad, or dialogue-replacement workflows, especially when 1080p output, voice cloning, and control over active-speaker detection matter. The free tier can support a brief evaluation, while paid tiers add watermark-free output or team features. It is less compelling for sustained high-volume translation when five minutes is the stated allowance on the listed paid tiers, or for footage where mouths are cropped or difficult to see.

Pros and cons

Pros: MP4 plus WAV/MP3 input through URL or upload offers practical integration choices; Python and TypeScript/Node.js SDKs provide defined developer entry points; 1080p output, voice cloning, and watermark-free output address common delivery needs.
Pros: Active-speaker detection can be disabled per request, giving developers a control beyond the automatic default. The stated European hosting and content-ownership terms may also matter to organizations assessing their workflow.
Cons: The free tier covers only two minutes and includes a watermark; the five-minute allowance on multiple paid tiers remains restrictive for recurring translation work.
Cons: Close-ups, cropped mouths, and extreme side views are difficult inputs, while plan-dependent concurrency complicates capacity planning.

Alternatives

For other options, compare the AI Video Lip Sync Tools directory. LipDub is another freemium API and web option with a free tier that includes one minute at 1080p with a watermark, alongside AI dubbing, voice cloning, and lip sync; consider it when that free allowance better matches a first trial.

Sync Labs offers API and web access with a free plan of three generations per month, each up to 20 seconds, plus separate text-to-speech generations. It may suit a user whose evaluation fits those short monthly limits. VEED has Android, browser extension, iOS, and web platforms; its free exports are 720p and watermarked, so it is an option when a broader platform mix matters more than clean free exports.

lipsyn.cc offers API and web access with a five-second free preview and a one-time Quick Take option; consider it when a short preview or one-off purchase suits better than CHAMELAION's subscription tiers. Morph Studio is a web freemium platform whose free plan includes monthly credits for text/image-to-video access to two models, text-to-image generation, video style transfer, and 90-day asset retention; it is oriented to those broader creative tools rather than the API workflow described above.

Rendley is another freemium API and web option, and its free plan has no card requirement or time limit. WeryAI Video Lip Sync offers Android, iOS, and web access with a yearly Basic plan; it is worth comparing when those platforms are a priority. EchoMimic is a free option across Linux, self-hosted, and web platforms.

Verdict

CHAMELAION LipSync API is a sensible choice for developers who need a clear video-and-audio lip-sync workflow, API tooling, and 1080p output with voice cloning. Its ownership and hosting terms are useful considerations for organizations, but the small included translation allowances and plan-dependent concurrency are meaningful constraints. Choose it for focused, controlled-volume workflows; look elsewhere if you need substantial translation minutes or dependable throughput beyond what your plan allows.
