# H3 Max Lip Sync Image to Video API

> Biến ảnh chân dung và tệp âm thanh thành video nói khớp môi, tối đa 2K

Tạo chuyển động cho một ảnh đơn để khẩu hình khớp với clip âm thanh được cung cấp. Âm thanh phải dài ít nhất 5 giây, hỗ trợ tối đa 15 phút và độ dài đầu ra khớp với âm thanh. Tỷ lệ khung hình ảnh phải từ 0.4 đến 2.5. `resolution` từ 480P đến 2K, còn `enable_transcription` có thể thêm bản chép lời để định hướng đồng bộ.

- Model id: `minimax/h3-max/lip-sync/image-to-video`
- Made by: MiniMax
- Category: Lipsync & Avatars
- Output: video
- Price per second of your input audio: from $0.05 / second of input audio (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.ru/v1/run/minimax/h3-max/lip-sync/image-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/minimax/h3-max/lip-sync/image-to-video`

## Pricing

Price: **from $0.05 / second of input audio** (the lowest tier; the quote prices your exact input). Price per second of your input audio: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

Price by tier:

- 480P: $0.05 / second of input audio
- 480P, over 15 s: $0.06 / second of input audio
- 768P: $0.08 / second of input audio
- 768P, over 15 s: $0.096 / second of input audio
- 1080P: $0.16 / second of input audio
- 1080P, over 15 s: $0.192 / second of input audio
- 2K: $0.32 / second of input audio
- 2K, over 15 s: $0.384 / second of input audio

The full example input below costs $0.80 = 800 API credits (10 s input audio × $0.08 (768P)).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/minimax/h3-max/lip-sync/image-to-video` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | Hình ảnh đầu vào cho hoạt ảnh; chỉ chấp nhận tỷ lệ khung hình trong khoảng 0.4–2.5. |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | Âm thanh điều khiển chuyển động miệng, với thời lượng được hỗ trợ từ 5 giây đến 15 phút. Video được tạo có cùng thời lượng với âm thanh. |
| `resolution` |  | enum (string) | no | `768P` | `480P`, `768P`, `1080P`, `2K` | Độ phân giải của đầu ra được tạo, sử dụng tỷ lệ khung hình được hỗ trợ gần nhất với tỷ lệ của hình ảnh. |
| `enable_transcription` |  | boolean | no | `false` |  | Hỗ trợ bản chép lời cho đồng bộ hóa môi. Khi tắt, đồng bộ hóa chỉ dùng âm thanh; khi bật, hệ thống chép lời âm thanh được cung cấp và dùng bản chép lời đó làm hướng dẫn. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 | Seed dùng cho tạo sinh ngẫu nhiên; bỏ qua sẽ khiến hệ thống chọn ngẫu nhiên. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Kiểm soát việc bật kiểm tra an toàn nội dung. |

File parameters (`image`, `audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "image": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
  "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}

A fuller example:

```json

  "image_url": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
  "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.ru/v1/run/minimax/h3-max/lip-sync/image-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/minimax/h3-max/lip-sync/image-to-video?wait=20", {

let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {

}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3-max/lip-sync/image-to-video", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.ru/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "minimax/h3-max/lip-sync/image-to-video",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
        "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
