CHAMELAION LipSync API

Overview

The service takes MP4 video and WAV or MP3 audio, supplied by public URL or direct upload, and generates a video with lip movements matched to the audio. It is available through an API and the web. CHAMELAION says its model preserves a speaker’s identity, speaking style, and expressions while adapting the mouth movements.

Automatic active-speaker detection can be disabled per request, useful when a workflow needs to control how multi-speaker clips are handled. Generation endpoints allow 60 requests per minute, but concurrent jobs vary by plan, so that request rate alone does not establish processing capacity.

Key features

• Developer access: Authentication uses a Bearer token or x-api-key header, except for the health endpoint. SDKs support Python 3.8+ and TypeScript/Node.js 18+, giving teams in those environments a direct integration path.
• Video constraints: Output resolution is 1080p, and the service supports voice cloning. Profile views can work when the mouth remains sufficiently visible, but extreme close-ups, side views beyond 90 degrees, and cropped mouths are difficult cases. It is a better match for footage with a clear view of the speaker than for tightly framed or highly oblique shots.
• Languages and usage: The supported-language count is 28. CHAMELAION describes translation into 30 languages, so confirm that the required language pair is covered before building a workflow around it.
• Data and rights: CHAMELAION says its servers are hosted in Europe and its subcontractors comply with GDPR or have signed Data Processing Agreements. Users retain ownership of generated videos; the company says it processes content for translation and dubbing.

Pricing

The plans pair token allowances with video-translation minutes, but the paid tiers do not all include the same lip-sync terms. Compare the stated allowance and video-length limits with the specific job before choosing a plan.

• Starter — 0.00 EUR per free: 24,000 tokens, stated as 2 minutes of video translation plus lip sync. Output carries a watermark; no credit card is required. This is a small no-card way to assess a workflow, not a substantial free production allowance.
• Basic — 4.00 EUR per year, billed Yearly: 60,000 tokens, equal to 5 minutes of video translation/lipsync, with videos of any size and length and no watermark. Its low annual price is appealing for light use, but five minutes is a tight quota.
• Bronze — 20.00 EUR per year, billed Yearly: 60,000 tokens and 5 minutes of video translation, a stated 60-minute video-length limit, and extra tokens available. This adds room for longer source videos and quota top-ups, but the plan description states translation minutes rather than a lip-sync allowance.
• Silver — 96.00 EUR per year, billed Yearly: 60,000 tokens and 5 minutes of video translation, plus 3 seats, a glossary, priority support, and SRT upload. It suits a small team that needs those collaboration and translation features; the same short stated minute allowance remains.
• Gold — 500.00 EUR per month, billed Monthly: 60,000 tokens and 5 minutes of video translation/lipsync, with 5 seats, glossary, priority support, and SRT upload. It offers the team features without an annual term, but the price is steep relative to the stated five-minute allowance.
• Enterprise — custom pricing: Individual pricing and tokens, premium support, and a custom contract suit organizations that need terms beyond the listed tiers.

Basic, Bronze, and Silver are billed yearly; Gold is billed monthly. No renewal terms are stated.

Platforms

CHAMELAION supports API and web access. The documented SDKs target Python 3.8+ and TypeScript/Node.js 18+, which makes it a practical fit for teams already using those runtimes, rather than a ready-made mobile-app workflow.

Who it's for

This is best for developers and small teams automating dubbing, translation, avatar speech, creative ads, or dialogue replacement who can work within short per-plan allowances and supply footage with visible mouths. European hosting and the stated subcontractor arrangements may matter to organizations evaluating data handling. It is less suitable for high-volume production on the listed tiers or footage dominated by extreme angles and close-ups.

Pros and cons

• Pro: URL or upload input, automatic speaker detection with a per-request switch, and SDKs for Python and TypeScript/Node.js support configurable integrations.
• Pro: Basic includes watermark-free output and videos of any size and length for 4.00 EUR per year, making it an inexpensive entry point for light work.
• Pro: Silver and Gold add seats, glossary, SRT upload, and priority support for teams with translation workflows.
• Con: The stated five-minute allowance on paid tiers limits how much work the low headline prices cover.
• Con: Extreme close-ups, side angles above 90 degrees, and cropped mouths are difficult, restricting the footage it can handle reliably.
• Con: Concurrent-job limits depend on plan, so teams cannot infer throughput from the 60-requests-per-minute rate alone.

Alternatives

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

• VEED is worth considering for readers who want Android, iOS, or browser-extension access alongside web; its free plan exports at 720p with a watermark.
• LipDub is another API-and-web freemium option with a free tier and trial; its Seed plan includes one minute at 1080p with a watermark, plus AI dubbing, voice cloning, and lip sync.
• Sync Labs offers an API-and-web free tier with three generations per month, capped at 20 seconds each, for readers whose needs fit short tests.
• lipsyn.cc offers a five-second preview without sign-up or a card, and a one-time Quick Take purchase displayed at €6.99 for five minutes; it may suit a single short job better than a recurring plan.
• Morph Studio is a web-based alternative for readers seeking a broader video and image creation toolset.
• WeryAI Video Lip Sync supports Android, iOS, and web, for readers who prefer mobile access.
• Rendley is an API-and-web freemium alternative with no free trial; its operator is identified as Onix Technologies SRL in Moldova.
• EchoMimic is a free project with Linux, web, and self-hosted options for readers seeking those deployment choices.

Verdict

Choose CHAMELAION LipSync API for a developer-led dubbing or translation workflow that needs configurable speaker detection, 1080p output, and an inexpensive watermark-free entry plan. The main reasons to look elsewhere are the five-minute paid-tier allowances and the model’s difficulty with extreme angles or cropped mouths; neither low annual pricing nor a high request rate removes those constraints.
