# Skill: effect/counter — "מונה מספרים" (Number counter)

A number counts up (or down) to a value — money, followers, years — with an optional progress bar.
מספר רץ עד ערך — כסף, עוקבים, שנים — עם פס התקדמות לבחירה.

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.

Send `X-Tag: <job name>` on every call of one video; `GET /v1/usage?tag=<job name>` returns what it cost.

## 1. On its own — one call

```jsonc
POST /v1/effects/counter             // x-wait-ms: 110000
{
  "video_url": "https://media.gpt.org.il/samples/sample-he.mp4",
  "start": 0.3,
  "duration": 4.2,
  "params": {
    "from": 0,
    "to": 100000,
    "label": "סופר עד",
    "bar": true,
    "ease": "in"
  }
}
```

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": "counter",
      "params": {
        "from": 0,
        "to": 100000,
        "label": "סופר עד",
        "bar": true,
        "ease": "in"
      },
      "start": 0.3,
      "duration": 4.2
    }
  ],
  "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 |
|---|---|---|---|
| `from` | `0` | number | Where the count starts |
| `to` | `100000` | number | Where it lands |
| `prefix` | `""` | string | Before the number ("₪", "$") |
| `suffix` | `""` | string | After the number |
| `label` | `""` | string | A small line above the number |
| `sub` | `""` | string | A line that lands when the count ends |
| `ease` | `"out"` | `in` · `out` · `linear` | in = slow then racing · out = racing then settling |
| `bar` | `false` | boolean | A progress bar filling with the count |
| `theme` | `"gold"` | `red` · `blue` · `gold` · `green` · `purple` · `black` | The card's glow colour |

GET `/v1/effects/counter` 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.
