# Void Video Inpainting API

> Noņem objektu no video kopā ar tā ietekmi uz ainu, izmantojot maskas video vai teksta maskas uzvedni

Izmanto `video_url` un `prompt`, kas apraksta vēlamo fonu. Norādiet `quad_mask_video_url` vai izmantojiet `mask_prompt`, lai ģenerētu masku. Vadīklas ietver `num_frames` (1-197), `num_inference_steps` (1-50), `guidance_scale`, `strength` un pēc izvēles lēnāku `enable_pass2_refinement` laika konsekvences nodrošināšanai.

- 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/lv/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 |  |  | Avota video URL, kas satur noņemšanai paredzēto objektu. |
| `quad_mask_video_url` |  | string (video URL) | no | `` |  | Noņemšanas maskas video URL; ja tā nav, lietotne izveido pagaidu video masku, izmantojot SAM-3 video galapunktu un `mask_prompt`, pēc tam automātiski pārveido to par quadmask. Labākajiem rezultātiem nodrošiniet VOID stila quadmask ar 4 pelēktoņu vērtībām: 255 saglabājamam fonam, 127 ietekmētajam reģionam, 63 pārklājumam un 0 noņemamajam objektam. Tiek pieņemtas arī bināras maskas, kur 255 nozīmē saglabāt un 0 — noņemt. |
| `mask_prompt` |  | string \| null | no |  |  | Maskas mērķa norādes SAM-3, lai izveidotu pagaidu maskas video, ja nav nodrošināts `quad_mask_video_url`. Norādiet, ko maskēt, piemēram, objektu vai personu, kas jānoņem no avota video. |
| `prompt` |  | string | yes |  |  | Apraksts, kas norāda, kādam jāizskatās fonam pēc objekta noņemšanas. |
| `enable_pass2_refinement` |  | boolean | no | `false` |  | Neobligāta VOID precizēšana, kas apmaina lēnāku apstrādi pret potenciāli labāku laika konsekvenci garākos klipos. Tā izmanto deformēta trokšņa precizēšanu kā 2. posmu pēc 1. posma. |
| `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.` |  | Negatīva uzvedne, kas apraksta nevēlamus rezultātus, lai novirzītu ģenerēšanu no tiem. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 50 | Trokšņa noņemšanas soļu skaits. Tā palielināšana uzlabo kvalitāti, bet palielina aizkavi. |
| `guidance_scale` |  | number | no | `1` | 0 – 20 | Klasifikatoru neizmantojošās vadības stiprums. |
| `strength` |  | number | no | `1` | 0 – 1 | Trokšņa noņemšanas stiprums, kur 1.0 nozīmē pilnīgu trokšņa noņemšanu. |
| `seed` |  | integer \| null | no |  |  | Sēkla, kas kontrolē nejaušību atkārtojamu rezultātu iegūšanai. |
| `num_frames` |  | integer | no | `85` | 1 – 197 | Pieprasītais temporālās secināšanas logs, ko aizmugursistēma pielāgo kādam no CogVideoX drošajiem izmēriem 69, 77, 85, ..., 197. Lai nodrošinātu temporālo saspiešanu un dalīšanu ielāpos, tiek izvēlēts tuvākais šāds izmērs. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Iespējo ģenerētā satura drošības pārbaudes. |

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", {

  }),
});
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.
