CHAMELAION LipSync API

CHAMELAION LipSync API turns supplied video and audio into a lip-synced video, best suited to developers building dubbing, translation, avatar, or advertising workflows. Its API access, SDKs, and free entry tier make it practical to evaluate, but the modest video allowance and source-framing constraints may rule it out for some production work.

Overview

The API accepts MP4 video and WAV or MP3 audio through public URLs or direct upload. Active-speaker detection runs automatically and can be disabled per request, a useful option when developers need to control how a clip is handled. CHAMELAION says its model preserves speaker identity, speaking style, and expressions while matching mouth movements to new audio.

The stated use cases include video dubbing and translation, AI avatars, UGC and creative ads, and dialogue replacement or personalization. The company describes translation into 30 languages, while the supported-languages count is 28; confirm that the languages needed for a workflow are covered.

Key features

• Developer workflow: Python 3.8+ and TypeScript/Node.js 18+ SDKs give developers a starting point for integrating the API. Generation endpoints allow 60 requests per minute; maximum concurrent jobs vary by plan, so that plan-specific limit matters for busy pipelines.
• Output and source footage: Output is 1080p. The API can handle profile views if the mouth stays sufficiently visible, but extreme close-ups, side views beyond 90 degrees, and cropped mouths are difficult cases. It is a less dependable fit for footage that frequently obscures the speaker’s mouth.
• Access and data: Requests use a Bearer token or x-api-key header, except at the health endpoint. CHAMELAION says its servers are hosted in Europe and its subcontractors comply with GDPR or have signed Data Processing Agreements. It also says users retain ownership of generated videos and content is processed for translation and dubbing.

Pricing

The free Starter plan costs nothing and provides 24,000 tokens, described as two minutes of video translation and lip sync. It requires no credit card, but adds a watermark, making it better for evaluation than clean client delivery.

Basic costs €4 a year, billed Yearly, for 60,000 tokens—equivalent to five minutes of video translation and lip sync—with no watermark and videos of any size and length. Its low price is attractive for light use, but the five-minute token allowance remains the practical constraint. Bronze costs €20 a year, billed Yearly, and also provides 60,000 tokens, five minutes of video translation, and extra tokens available; it states a 60-minute video length. The published Bronze allowance is for translation, not explicitly lip sync, so buyers should distinguish the two workflows.

Silver costs €96 a year, billed Yearly, and includes 60,000 tokens, five minutes of video translation, three seats, a glossary, priority support, and SRT upload. It suits small teams that value those collaboration and support features, though its stated allowance is still short. Gold costs €500 a month, billed Monthly, and includes 60,000 tokens, five minutes of video translation and lip sync, five seats, a glossary, priority support, and SRT upload. That is a substantial step up in price for a small stated allowance; its team features and monthly billing may matter more than cost efficiency for some buyers. Enterprise has custom pricing and tokens, premium support, and a custom contract.

Voice cloning is supported. The pricing terms do not state a trial length, renewal conditions, or plan-specific concurrency caps.

Platforms

CHAMELAION offers API and web access. That gives developers an integration route alongside a web option, while the SDKs target Python and TypeScript/Node.js environments.

Who it's for

This is most compelling for developers and organizations translating or dubbing video, or building avatar and ad workflows, who can work within token limits and supply footage with a visible mouth. Teams needing multiple seats, glossaries, SRT upload, or priority support have a clearer fit in Silver or Gold. It is less suitable when clips regularly violate the framing constraints or when a workflow needs substantially more than five minutes under the stated paid allowances.

Pros and cons

Pros

• Public-URL and direct-upload input support both automated and direct submission workflows.
• Automatic speaker detection can be disabled per request, offering control over speaker handling.
• Starter requires no credit card, and Basic removes the watermark at a low annual price.
• European hosting, stated GDPR-related subcontractor terms, and user ownership of generated videos address important deployment considerations.

Cons

• The free allowance is two minutes and watermarked; paid plans generally state only five minutes, so sustained use may require extra tokens or a different arrangement.
• Profile views work only when the mouth remains visible; extreme close-ups, steep side views, and cropped mouths are difficult footage.
• The language claims differ: 30 languages are described for translation, while the supported-language count is 28.

Alternatives

AI Video Lip Sync Tools is a useful starting point for comparing options in the same category.

• VEED is worth considering for a broader web, mobile, or browser-extension workflow; its Free plan exports only in 720p and adds a watermark, while Creator exports up to 1080p.
• Muse is a free, open-source choice when the need is MIDI output rather than lip-synced video.
• SadTalker is an alternative for users who prefer offline, self-hosted open-source software.
• LipDub offers a free tier with one minute at 1080p, watermarking, AI dubbing, voice cloning, and lip sync; consider it if that combination better fits an initial trial.
• lipsyn.cc offers a no-sign-up, no-card five-second preview and a one-time €6.99 option for five minutes, making it an alternative for a short, discrete job.
• Rendley is another freemium API and web option.
• Sync Labs offers a free tier with three generations per month, each capped at 20 seconds, plus text-to-speech generations; consider it for tightly limited testing.
• Morph Studio is a web-based freemium option with a broader set of video and image generation tools.

Verdict

Choose CHAMELAION LipSync API if you need an API-led dubbing or translation workflow, value its speaker controls and European hosting, and can fit your usage into its token allowance. Look elsewhere if your clips often obscure the mouth, you need predictable high concurrency, or your ongoing volume makes the stated five-minute paid allowances a poor fit.
