# Skill: effect/icon-crack — "אייקון נסדק" (Icon crack)

An icon on its tile cracks in two: a bright zigzag flashes, the halves slide apart and tilt, then fade to a grey ghost.
אייקון על אריח נסדק לשניים: זיגזג בוהק מבליח, החצאים זזים לצדדים ונוטים, ואז דועכים לרוח רפאים אפורה.

Price: **60 credits per finished minute**: the render itself — 1 credit per second of 1080p output. Combined with captions, a hook or other effects: still one render, nothing more for combining.

## 1. On its own — one call

```jsonc
POST /v1/effects/icon-crack             // x-wait-ms: 110000
{
  "video_url": "https://media.gpt.org.il/samples/sample-he.mp4",
  "start": 0.2,
  "duration": 2.9,
  "params": {
    "backdrop": "panel",
    "crack_ms": 1300
  }
}
```

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-crack",
      "params": {
        "backdrop": "panel",
        "crack_ms": 1300
      },
      "start": 0.2,
      "duration": 2.9
    }
  ],
  "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.
