## 1. On its own — one call

```jsonc
POST /v1/effects/icon-fly-in             // x-wait-ms: 110000
{
  "video_url": "https://media.gpt.org.il/samples/sample-he.mp4",
  "start": 0.2,
  "duration": 3.4,
  "params": {
    "items": [
      {
        "url": "https://media.gpt.org.il/lookbook/effects/assets/icon-video.png",
        "x": 23,
        "y": 16,
        "size": 22,
        "from_x": -25,
        "from_y": 25
      },
      {
        "url": "https://media.gpt.org.il/lookbook/effects/assets/icon-chat.png",
        "x": 50,
        "y": 11,
        "size": 22,
        "from_x": 30,
        "from_y": 20
      },
      {
        "url": "https://media.gpt.org.il/lookbook/effects/assets/icon-sparkle.png",
        "x": 77,
        "y": 16,
        "size": 22,
        "from_x": 22,
        "from_y": 28
      }
    ]
  }
}
```

A normal render: `status: processing` → poll `GET /v1/executions/{id}` until `completed`, then read `output.url`.

When it plays: a stretch: `start` + `duration` (seconds of the finished video), or `at` (a word id) + `duration`, or `during` { from, to } (word ids).

## 2. With captions, a hook and other effects — the same render

```jsonc
POST /v1/studio/edit               // x-wait-ms: 110000
{
  "video_url": "<the video>",
  "language_code": "he",
  "captions": {
    "style": "classic"
  },
  "effects": [
    {
      "id": "icon-fly-in",
      "params": {
        "items": [
          {
            "url": "https://media.gpt.org.il/lookbook/effects/assets/icon-video.png",
            "x": 23,
            "y": 16,
            "size": 22,
            "from_x": -25,
            "from_y": 25
          },
          {
            "url": "https://media.gpt.org.il/lookbook/effects/assets/icon-chat.png",
            "x": 50,
            "y": 11,
            "size": 22,
            "from_x": 30,
            "from_y": 20
          },
          {
            "url": "https://media.gpt.org.il/lookbook/effects/assets/icon-sparkle.png",
            "x": 77,
            "y": 16,
            "size": 22,
            "from_x": 22,
            "from_y": 28
          }
        ]
      },
      "start": 0.2,
      "duration": 3.4
    }
  ],
  "audio": {
    "normalize": true
  },
  "output": {
    "aspect_ratio": "9:16",
    "resolution": "1080",
    "fit": "crop",
    "quality": "high"
  }
}
```

`effects` is a list: add more entries for more effects. The engine applies them by pipeline stage (cuts and time →
camera → grade and looks → overlays → text and captions → sound), never by their order in the list. An edit has one
`transition`, one `color` grade, one `music` bed, one `speed` and one caption style: two effects that set the same
one are refused with a message that names them.

## 3. Params

| param | default | range / options | what it does |
|---|---|---|---|
| `items` | **required** | list | The icons, in the order they arrive |
| `radius` | `22` | 0–50 | Corner radius, % of the icon |
| `stagger_ms` | `250` | 0–2000 | Between one icon and the next, ms |
| `fly_ms` | `300` | 100–1500 | How long one flight takes, ms |

GET `/v1/effects/icon-fly-in` returns the same as JSON (with the full body schema). Every field has a default; numbers
outside their range are refused with the field's name.
