# H3 Max Lip Sync Image to Video API

> Mengubah gambar potret dan file audio menjadi video berbicara yang tersinkronisasi dengan gerakan bibir, hingga 2K

Menganimasikan satu gambar agar gerakan mulut mengikuti klip audio yang diberikan. Audio harus berdurasi minimal 5 detik, mendukung hingga 15 menit, dan durasi output menyesuaikan audio. Rasio aspek gambar harus antara 0.4 dan 2.5. `resolution` berkisar dari 480P hingga 2K, dan `enable_transcription` dapat menambahkan transkrip untuk memandu sinkronisasi.

- 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`
- Docs page: https://doitong.com/id/developers/models/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 |  |  | Gambar input animasi; hanya rasio aspek dalam rentang 0.4–2.5 yang diterima. |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | Audio penggerak gerakan mulut, dengan durasi yang didukung dari 5 detik hingga 15 menit. Video yang dibuat memiliki durasi yang sama dengan audio. |
| `resolution` |  | enum (string) | no | `768P` | `480P`, `768P`, `1080P`, `2K` | Resolusi output yang dibuat, menggunakan rasio aspek yang didukung dan paling mendekati rasio gambar. |
| `enable_transcription` |  | boolean | no | `false` |  | Bantuan transkripsi untuk sinkronisasi bibir. Jika dinonaktifkan, sinkronisasi hanya menggunakan audio; jika diaktifkan, audio yang disediakan ditranskripsikan dan transkrip tersebut digunakan sebagai panduan. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 | Seed untuk pembuatan acak; jika tidak disertakan, seed dipilih secara acak. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Mengontrol apakah penyaringan keamanan konten diaktifkan. |

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",

}
```

## 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

```javascript

const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "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 = {
    "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 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.

### Output fields (`output`)

| Field | Type | Description |
|---|---|---|
| `video` | object {url, content_type, file_name, file_size} | Video dengan gerakan bibir yang disinkronkan dan trek audio yang disediakan. |
