# H3 Max Lip Sync Image to Video API

> يحوّل صورة شخصية وملفًا صوتيًا إلى فيديو ناطق متزامن الشفاه، بدقة تصل إلى 2K

يحرّك صورة واحدة بحيث تتبع حركات الفم مقطعًا صوتيًا مقدّمًا. يجب ألا تقل مدة الصوت عن 5 ثوانٍ، ويدعم حتى 15 دقيقة، وتطابق مدة الناتج مدته. يجب أن تتراوح نسبة عرض الصورة إلى ارتفاعها بين 0.4 و2.5. تتراوح `resolution` من 480P إلى 2K، ويمكن لـ`enable_transcription` إضافة نص مفرّغ لتوجيه المزامنة.

- 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/ar/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 |  |  | صورة مدخل الرسوم المتحركة؛ لا تُقبل إلا نسب الأبعاد ضمن النطاق 0.4–2.5. |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | الصوت الذي يوجّه حركات الفم، بمدة مدعومة تتراوح من 5 ثانية إلى 15 دقيقة. تكون مدة الفيديو المولَّد مطابقة لمدة الصوت. |
| `resolution` |  | enum (string) | no | `768P` | `480P`, `768P`, `1080P`, `2K` | دقة المخرج المولد، باستخدام أقرب نسبة أبعاد مدعومة إلى نسبة الصورة. |
| `enable_transcription` |  | boolean | no | `false` |  | مساعدة تفريغ لمزامنة حركة الشفاه. عند تعطيل هذا الخيار، تستخدم المزامنة الصوت وحده؛ وعند تفعيله، تُفرَّغ المادة الصوتية المقدَّمة ويُستخدم التفريغ كإرشاد. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 | بذرة التوليد العشوائي؛ يؤدي حذفها إلى اختيار عشوائي. |
| `enable_safety_checker` |  | boolean | no | `true` |  | تحدد ما إذا كان فحص أمان المحتوى مفعّلًا. |

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"
```

# 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":

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.
