# Void Video Inpainting API

> מסיר אובייקט מווידאו ואת השפעותיו על הסצנה, באמצעות וידאו מסכה או הנחיית מסכת טקסט

מקבל `video_url` ו־`prompt` שמתאר את הרקע הרצוי. יש לספק `quad_mask_video_url`, או להגדיר `mask_prompt` כדי ליצור מסכה. הפקדים כוללים `num_frames` (1-197), `num_inference_steps` (1-50), `guidance_scale`, `strength` ואת `enable_pass2_refinement` האופציונלי והאיטי יותר, לשמירה על עקביות בזמן.

- Model id: `void-video-inpainting`
- Made by: Open model
- Category: Video to Video
- Output: video
- Price per run: from $0.10 / run (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/void-video-inpainting`
- Quote: `POST https://api.doitong.com/v1/quote/void-video-inpainting`
- Docs page: https://doitong.com/he/developers/models/void-video-inpainting

## Pricing

Price: **from $0.10 / run** (the lowest tier; the quote prices your exact input). Price per run: 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.

The full example input below costs $0.10 = 100 API credits (1 run × $0.10).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/void-video-inpainting` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | כתובת URL של וידאו מקור המכיל את האובייקט המיועד להסרה. |
| `quad_mask_video_url` |  | string (video URL) | no | `` |  | כתובת URL של וידאו מסכת ההסרה; אם היא חסרה, האפליקציה יוצרת מסכת וידאו זמנית דרך נקודת הקצה של וידאו SAM-3 באמצעות `mask_prompt`, ואז ממירה אותה אוטומטית ל-quadmask. לתוצאות מיטביות, ספקו quadmask בסגנון VOID באמצעות 4 ערכי גווני אפור: 255 לרקע שנשמר, 127 לאזור המושפע, 63 לחפיפה ו-0 לאובייקט שמוסר. מתקבלות גם מסכות בינאריות, באמצעות 255 לשמירה ו-0 להסרה. |
| `mask_prompt` |  | string \| null | no |  |  | הוראות למיקוד המסכה עבור SAM-3 ליצירת מסכה זמנית כאשר לא סופק `quad_mask_video_url`. ציינו מה להסוות, למשל אובייקט או אדם שיש להסיר מווידאו המקור. |
| `prompt` |  | string | yes |  |  | תיאור המציין כיצד הרקע אמור להיראות לאחר הסרת האובייקט. |
| `enable_pass2_refinement` |  | boolean | no | `false` |  | עידון VOID אופציונלי שמחליף עיבוד איטי יותר בעקביות זמנית טובה יותר, פוטנציאלית, בקטעים ארוכים. הוא מחיל עידון רעש מעוות כ-Pass 2, לאחר Pass 1. |
| `negative_prompt` |  | string | no | `The video is not of a high quality, it has a low resolution. Watermark present in each frame. The background is solid. Strange body and strange trajectory. Distortion.` |  | הנחיה שלילית המתארת תוצאות לא רצויות, כדי להסיט את היצירה מהן. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 50 | מספר שלבי ניקוי הרעש. הגדלתו משפרת את האיכות אך מוסיפה זמן המתנה. |
| `guidance_scale` |  | number | no | `1` | 0 – 20 | עוצמת הנחיה ללא מסווג. |
| `strength` |  | number | no | `1` | 0 – 1 | עוצמת ניקוי הרעש, כאשר 1.0 מציין ניקוי רעש מלא. |
| `seed` |  | integer \| null | no |  |  | Seed השולט באקראיות לקבלת תוצאות שניתנות לשחזור. |
| `num_frames` |  | integer | no | `85` | 1 – 197 | חלון ההסקה הזמני המבוקש, המותאם על ידי ה-backend לאחד מהגדלים הבטוחים ל-CogVideoX: 69, 77, 85, ..., 197. נבחר הגודל הקרוב ביותר כדי להתאים לדחיסה זמנית ולחלוקה לטלאים. |
| `enable_safety_checker` |  | boolean | no | `true` |  | הפעלת בדיקות בטיחות לתוכן שנוצר. |

File parameters (`video`, `quad_mask_video_url`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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.com/v1/run/void-video-inpainting?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

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

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
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/void-video-inpainting?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

  }),
});
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.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/void-video-inpainting", 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.com/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": "void-video-inpainting",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
