Volcengine Lip Sync provides a focused video-to-video lip-sync endpoint through RunAPI with unified API, SDK, CLI, Bruno, and docs coverage.
A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.
Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.
Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.
It requires one public source video URL and one public source audio URL.
Use `lite` for frontal single-person videos and faster processing. Use `basic` when the scene is more complex and you need scene detection.
It suppresses background noise by separating vocals before driving the lip movement.
`align_audio`, `align_audio_reverse`, and `template_start_seconds` are available in `lite` mode only.
The completed response returns generated video URLs in `videos`.
Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
