# H3 Max Camera Controls API

> Animiert ein Bild entlang eines Keyframe-Kamerapfads mit Steuerung von Umlauf, Höhe und Abstand

Verwendet `image_url` als erstes Bild und bewegt die Kamera entlang von `camera_trajectory`, einer Liste aus 2 bis 12 geordneten Keyframes. Standardmäßig bleibt die Szene starr, sodass sich nur die Kamera bewegt. Die Dauer beträgt 0.92 bis 15 Sekunden bei einer Auflösung von 480P, 768P oder 1080P. Die Prompt-Erweiterung kann angepasst werden.

- Model id: `minimax/h3-max/camera-controls`
- Made by: MiniMax
- Category: Image to Video
- Output: video
- Price: from $0.0325 / second (5 s ≈ $0.163) (cheapest run $0.163 (163 API credits))
- Run: `POST https://api.doitong.com/v1/run/minimax/h3-max/camera-controls`

## Pricing

Price: **from $0.0325 / second (5 s ≈ $0.163)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 768P: $0.052 (52 API credits) / second
- When `resolution` = 1080P: $0.104 (104 API credits) / second

The full example input below costs $0.163 = 163 API credits (5 s × 32.5 API credits).

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/minimax/h3-max/camera-controls` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | no | `The same elements in the reference are rigid. Preserve every element exactly. The entire scene is frozen. Only the camera moves. no scene motion only camera motion` | ≤ 50000 characters | Prompt für die Video-Generierung, der das Standardverhalten einer eingefrorenen Szene überschreibt. Leer lassen oder weglassen, um die Referenzszene beizubehalten und nur Kamerabewegungen zuzulassen. |
| `duration` |  | number | no | `5` | 0.92 – 15 | Angeforderte Dauer in Sekunden; die tatsächliche Videolänge kann bis zu etwa 0.7 s darüber liegen. |
| `resolution` |  | enum (string) | no | `480P` | `480P`, `768P`, `1080P` | Auswahl der Generierungsauflösung: Für 1080P ist eine latente Verfeinerung des nativ mit 768P generierten Materials erforderlich, statt einer nativen Generierung in der ausgewählten Auflösung. |
| `seed` |  | integer \| null | no |  |  | Seed für die zufällige Generierung; wenn nicht angegeben, wird zufällig einer ausgewählt. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Aktivierung der Sicherheitsprüfung; true aktiviert die Prüfung. |
| `prompt_expansion_mode` |  | string | yes | `balanced` |  | Aufwand für die Prompt-Umschreibung vor der Generierung: 'quality' entwickelt über bis zu etwa 30 s einen ausführlicheren Prompt, während 'balanced' in ungefähr einer Sekunde zurückkehrt. Wähle 'disabled', um die Prompt-Erweiterung zu überspringen. |
| `image_url` | `image` | string (image URL) | yes |  | ≥ 1 characters | Bild-URL, die das Start-Frame des Videos festlegt. |
| `camera_trajectory` |  | array of object {time, azimuth, elevation, distance} | no |  | 2 – 12 items | Geordnete Kamera-Keyframes mit beibehaltenen vollständigen Drehungen und einer auf 32 Umdrehungen begrenzten Gesamt-Azimutbewegung. Außerhalb des Zeitraums der Keyframes hält die Kamera vor dem Zeitstempel die erste Position und bis zum Videoende die letzte Position. |
| `camera_trajectory[].time` |  | number | yes |  | 0 – 1 | Normalisierte Zeit innerhalb des Videos; das Intervall [0, 1] repräsentiert jeweils Anfang und Ende. |
| `camera_trajectory[].azimuth` |  | number | yes |  |  | Horizontaler Winkel der Kamera um das Motiv, gemessen in Grad. |
| `camera_trajectory[].elevation` |  | number | yes |  | -90 – 90 | Vertikaler Winkel der Kamera zum Motiv, gemessen in Grad. |
| `camera_trajectory[].distance` |  | number | yes |  | > 0 | Abstand zwischen Kamera und Motiv, gemessen in normalisierten Szeneneinheiten. |

File parameters (`image`) 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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "prompt_expansion_mode": "balanced"
}
```

A fuller example:

## 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/minimax/h3-max/camera-controls?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "prompt_expansion_mode": "balanced"
  }'

# 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

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

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3-max/camera-controls", 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": "minimax/h3-max/camera-controls",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "prompt_expansion_mode": "balanced"
      },
      "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.

### Output fields (`output`)

| Field | Type | Description |
|---|---|---|
| `video` | object {url, content_type, file_name, file_size} | Vom Modell erzeugtes Video. |
| `expanded_prompt` | string \| null | Für das Modell erweiterter Prompt oder null, wenn kein erweiterter Text verfügbar ist. null tritt bei deaktivierter Erweiterung, unveränderter Erweiterung und intern von der gehosteten API des Modells verarbeiteter Erweiterung auf. |
| `timings` | object \| null | Zeitmessungen in Sekunden, nur auf Routen verfügbar, die Backend-Zeitmessungen melden; andernfalls null. Der Eintrag 'inference' misst, wie lange die DiT-Entrauschung auf dem GPU-Backend gedauert hat. |
