# Void Video Inpainting API

> Eltávolít egy objektumot a videóból, a jelenetre gyakorolt hatásaival együtt, maszkvideó vagy szöveges maszkprompt használatával

A `video_url` mellett a kívánt hátteret leíró `prompt` értéket fogad. Adj meg `quad_mask_video_url` értéket, vagy használd a `mask_prompt` mezőt maszk generálásához. A vezérlők között szerepel a `num_frames` (1-197), a `num_inference_steps` (1-50), a `guidance_scale`, a `strength`, valamint a lassabb, opcionális `enable_pass2_refinement` az időbeli következetességhez.

- Model id: `void-video-inpainting`

- 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/hu/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 |  |  | A removal célpontját tartalmazó forrásvideó URL-je. |
| `quad_mask_video_url` |  | string (video URL) | no | `` |  | A removal-maszk videó-URL-je; ha hiányzik, az alkalmazás ideiglenes videómaszkot hoz létre a SAM-3 videó-végponton a `mask_prompt` használatával, majd automatikusan quadmaskké alakítja. A legjobb eredményhez VOID-stílusú quadmasket adjon meg 4 szürkeárnyalattal: 255 a megtartott háttérhez, 127 az érintett régióhoz, 63 az átfedéshez, 0 pedig az eltávolítandó objektumhoz. Bináris maszkok is elfogadottak: 255 a megtartáshoz és 0 az eltávolításhoz. |
| `mask_prompt` |  | string \| null | no |  |  | Maszkolási utasítások a SAM-3 számára ideiglenes maszkvideó létrehozásához, ha nincs megadva `quad_mask_video_url`. Adja meg, mit kell maszkolni, például a forrásvideóból eltávolítandó objektumot vagy személyt. |
| `prompt` |  | string | yes |  |  | Azt meghatározó leírás, hogyan nézzen ki a háttér az objektum eltávolítása után. |
| `enable_pass2_refinement` |  | boolean | no | `false` |  | Opcionális VOID-finomítás, amely a lassabb feldolgozásért cserébe potenciálisan jobb időbeli konzisztenciát biztosít hosszabb klipeknél. A Pass 1 után, Pass 2-ként alkalmazza a torzított zaj finomítását. |
| `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.` |  | A nem kívánt eredményeket leíró negatív prompt, amely eltereli a generálást ezektől. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 50 | Zajcsökkentési lépések száma. Növelése javítja a minőséget, ugyanakkor növeli a késleltetést. |
| `guidance_scale` |  | number | no | `1` | 0 – 20 | A classifier-free guidance erőssége. |
| `strength` |  | number | no | `1` | 0 – 1 | A zajcsökkentés erőssége; az 1.0 teljes zajcsökkentést jelez. |
| `seed` |  | integer \| null | no |  |  | Az ismételhető eredmények véletlenszerűségét szabályozó seed. |
| `num_frames` |  | integer | no | `85` | 1 – 197 | A kért időbeli következtetési ablak, amelyet a backend a CogVideoX által biztonságosan használható 69, 77, 85, ..., 197 méretek egyikére módosít. Az időbeli tömörítés és a csempézés támogatásához a legközelebbi ilyen méretet választja. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Biztonsági ellenőrzéseket engedélyez a generált tartalomhoz. |

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

  "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

### 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",

# 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.
