# Video · Erase · Keypoints API

> Entfernt ein Objekt aus einem kurzen Video, ausgewählt durch Klicken auf positive und negative Keypoints

Entfernt ein Objekt aus einem Video, wobei das Ziel durch eine Liste von `keypoints` als positive oder negative x/y-Punkte ausgewählt wird. Das Eingabevideo muss kürzer als 5 Sekunden sein; `auto_trim` kürzt längere Clips auf diese Arbeitslänge. Das Ausgabeformat kann aus elf Containern und Codecs gewählt werden, standardmäßig mp4_h264; `preserve_audio` behält den Ton bei.

- Model id: `bria/video/erase/keypoints`
- Made by: Bria AI
- Category: Video to Video
- Output: video
- Price per second of your input video: $0.14 / second of input video (cheapest run $0.14 (140 API credits))
- Run: `POST https://api.doitong.com/v1/run/bria/video/erase/keypoints`
- Quote: `POST https://api.doitong.com/v1/quote/bria/video/erase/keypoints`
- Docs page: https://doitong.com/de/developers/models/bria/video/erase/keypoints

## Pricing

Price: **$0.14 / second of input video**. Price per second of your input video: 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 $0.70 = 700 API credits (5 s input video × $0.14).

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/bria/video/erase/keypoints` 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 |
|---|---|---|---|---|---|---|
| `output_container_and_codec` |  | enum (string) | no | `mp4_h264` | `mp4_h265`, `mp4_h264`, `webm_vp9`, `gif`, `mov_h264`, `mov_h265`, `mov_proresks`, `mkv_h264`, `mkv_h265`, `mkv_vp9`, `mkv_mpeg4` | Container und Codec für die Ausgabe, ausgewählt aus: mp4_h265, mp4_h264, webm_vp9, gif, mov_h264, mov_h265, mov_proresks, mkv_h264, mkv_h265, mkv_vp9, mkv_mpeg4. |
| `auto_trim` |  | boolean | no | `true` |  | Kürzt das Video automatisch auf die Arbeitslänge von 5 Sekunden. |
| `preserve_audio` |  | boolean | no | `true` |  | Die Beibehaltung von Audio im Ausgabevideo ist aktiviert, wenn true gesetzt ist. |
| `keypoints` |  | array of string | yes |  |  | Punkte für das Entfernen oder Beibehalten von Videoinhalten, angegeben durch [x,y]-Koordinaten und jeweils mit dieser Syntax: {'x':100, 'y':100, 'type':'positive/negative'}. |
| `video_url` | `video` | string (video URL) | yes |  |  | Video mit weniger als 5 Sekunden, das als Quelle für die Objektlöschung dient. |

File parameters (`video`) 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
{
  "keypoints": [
    "{'x': 765, 'y': 344, 'type': 'positive'}",
    "{'x': 200, 'y': 200, 'type': 'negative'}"
  ],
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "keypoints": [
    "{'x': 765, 'y': 344, 'type': 'positive'}",
    "{'x': 200, 'y': 200, 'type': 'negative'}"
  ],
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

## 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/bria/video/erase/keypoints?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "keypoints": [
      "{'\''x'\'': 765, '\''y'\'': 344, '\''type'\'': '\''positive'\''}",
      "{'\''x'\'': 200, '\''y'\'': 200, '\''type'\'': '\''negative'\''}"
    ],
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# 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

payload = {
    "keypoints": [

```

### 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": "bria/video/erase/keypoints",
      "input": {
        "keypoints": [
          "{'x': 765, 'y': 344, 'type': 'positive'}",
          "{'x': 200, 'y': 200, 'type': 'negative'}"
        ],
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "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.
