# H3 Max Lip Sync Image to Video API

> پورٹریٹ تصویر اور آڈیو فائل کو لپ سنک والی بولتی ویڈیو میں بدلتا ہے، 2K تک

ایک تصویر کی اینیمیشن بناتا ہے تاکہ منہ کی حرکات فراہم کردہ آڈیو کلپ کے مطابق ہوں۔ آڈیو کم از کم 5 سیکنڈ کی ہونی چاہیے، 15 منٹ تک معاونت حاصل ہے، اور آؤٹ پٹ کا دورانیہ اسی کے مطابق ہوتا ہے۔ تصویر کی نسبتِ ابعاد 0.4 اور 2.5 کے درمیان ہونی چاہیے۔ `resolution` کی حد 480P سے 2K ہے، اور `enable_transcription` ہم وقت سازی کی رہنمائی کے لیے تحریری نقل شامل کر سکتا ہے۔

- 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/ur/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 |  |  | Animation ان پٹ تصویر؛ صرف 0.4–2.5 range کے اندر aspect ratios قبول کیے جاتے ہیں۔ |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | منہ کی حرکات چلانے والا آڈیو، جس کا معاون دورانیہ 5 سیکنڈ سے 15 منٹ تک ہے۔ تیار کردہ ویڈیو کا دورانیہ آڈیو کے برابر ہوتا ہے۔ |
| `resolution` |  | enum (string) | no | `768P` | `480P`, `768P`, `1080P`, `2K` | تیار کردہ آؤٹ پٹ کا ریزولوشن، جس میں تصویر کے قریب ترین معاون aspect ratio استعمال ہوتا ہے۔ |
| `enable_transcription` |  | boolean | no | `false` |  | Lip synchronization کے لیے transcript assistance۔ اسے disabled کرنے پر synchronization صرف آڈیو استعمال کرتی ہے؛ enabled کرنے پر فراہم کردہ آڈیو کا transcript بنا کر اسے رہنمائی کے طور پر استعمال کیا جاتا ہے۔ |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 | بے ترتیب تخلیق کے لیے seed؛ نہ دینے پر بے ترتیب انتخاب کیا جاتا ہے۔ |
| `enable_safety_checker` |  | boolean | no | `true` |  | یہ کنٹرول کرتا ہے کہ content safety screening enabled ہے یا نہیں۔ |

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", {

### 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.
