# MiniMax H3 Max lip sync image to video

Needs image url and audio url. Served by fal.ai.

H3 Max Lip Sync Image to Video, served by fal.ai. The OpenAPI schema for the minimax/h3-max/lip-sync/image-to-video queue. Price: Billing is calculated per second of generated video. Video costs $0.05 per second at 480p, $0.08 per second at 768p, $0.16 per second at 1080p, and $0.32 per second at 2K. A 1.2x multiplier is added to videos over 15 seconds. A 5-second video at 768p costs $0.40. A 30-second video at 768p costs $2.88. Actual-cost billing: the initial reservation is an estimate, not a maximum. 5 seconds at 1080p ($0.16/s); longer audio and the 1.2x multiplier above 15 seconds may increase cost. The unique Billing Events receipt for this exact endpoint and request_id is the final USD charge, including usage above the estimate. Missing receipts retain the reservation for reconciliation; no guessed final fee. Asynchronous: returns a request_id; poll fal/status and fetch fal/result with model "minimax/h3-max" and that request_id. Billed once, when the result is ready; a generation that fails is refunded.

## Published example

This is the provider tool’s published example. Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection.

  "tool_id": "fal/minimax-h3-max-lip-sync-image-to-video",

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

This tool uses deferred settlement. Follow its returned task/run instructions; preserve the existing reservation until the result is reconciled.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
