# Void Video Inpainting API

> Bidh e a’ toirt air falbh nì à bhidio còmhla ris na buaidhean aige air an t-sealladh, a’ cleachdadh bhidio masg no prompt masg teacsa

Gabhaidh e `video_url` agus `prompt` a tha a’ mìneachadh a’ chùl-fhiosrachaidh a tha thu ag iarraidh. Thoir seachad `quad_mask_video_url`, no thoir `mask_prompt` gus masg a ghineadh. Am measg nan smachdan tha `num_frames` (1-197), `num_inference_steps` (1-50), `guidance_scale`, `strength` agus `enable_pass2_refinement` roghainneil, nas slaodaiche, airson cunbhalachd ùineail.

- 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/gd/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 |  |  | URL bhidio tùsail anns a bheil an nì a tha ri thoirt air falbh. |
| `quad_mask_video_url` |  | string (video URL) | no | `` |  | URL bhidio na maise toirt air falbh; mura h-eil e ann, cruthaichidh an aplacaid masg bhidio sealach tro phuing-crìche bhidio SAM-3 a’ cleachdadh `mask_prompt`, agus tionndaidhidh e gu quadmask e gu fèin-obrachail. Airson nan toraidhean as fheàrr, solar quadmask ann an stoidhle VOID a’ cleachdadh 4 luachan liath-sgèile: 255 airson cùl-raon glèidhte, 127 airson na roinne air a bheil buaidh, 63 airson tar-lùbadh, agus 0 airson an nì a tha ga thoirt air falbh. Gabhar ri maisgean dà-thaobhach cuideachd, a’ cleachdadh 255 airson gleidheadh agus 0 airson toirt air falbh. |
| `mask_prompt` |  | string \| null | no |  |  | Stiùiridhean targaid na maise airson SAM-3 gus bhidio maise sealach a chruthachadh nuair nach eil `quad_mask_video_url` air a solar. Sònraich dè bu chòir a mhasgadh, mar eisimpleir nì no duine a thèid a thoirt às a’ bhidio thùsail. |
| `prompt` |  | string | yes |  |  | Tuairisgeul a’ sònrachadh cò ris a bu chòir don chùl-raon coimhead às dèidh an nì a thoirt air falbh. |
| `enable_pass2_refinement` |  | boolean | no | `false` |  | Ùrachadh VOID roghainneil a nì giullachd nas slaodaiche airson cunbhalachd ùineail a dh’fhaodadh a bhith nas fheàrr ann an criomagan nas fhaide. Bidh e a’ cur ùrachadh fuaim air a shaobhadh an sàs mar Pass 2, às dèidh 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.` |  | Prompt àicheil a’ toirt cunntas air toraidhean nach eilear ag iarraidh gus an gineadh a stiùireadh air falbh bhuapa. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 50 | Cunntas cheumannan dì-fhuaimneachaidh. Le bhith ga mheudachadh bidh càileachd nas fheàrr ann ach latency a bharrachd. |
| `guidance_scale` |  | number | no | `1` | 0 – 20 | Neart stiùiridh gun chlasadair. |
| `strength` |  | number | no | `1` | 0 – 1 | Neart dì-fhuaimneachaidh, le 1.0 a’ comharrachadh dì-fhuaimneachadh iomlan. |
| `seed` |  | integer \| null | no |  |  | Sìol a bhios a’ cumail smachd air thuaireamachd airson toraidhean ath-riochdachadh. |
| `num_frames` |  | integer | no | `85` | 1 – 197 | Uinneag co-dhùnaidh ùineail a chaidh iarraidh, air atharrachadh leis a’ backend gu aon de na meudan CogVideoX-sàbhailte 69, 77, 85, ..., 197. Thèid am meud as fhaisge a thaghadh gus teannachadh ùineail agus paisteadh a ghabhail a-steach. |
| `enable_safety_checker` |  | boolean | no | `true` |  | A’ comasachadh sgrùdaidhean sàbhailteachd airson susbaint a chaidh a ghineadh. |

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

  "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",

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.
