# Icon morph · אייקון שמשתנה

`POST /v1/effects/icon-morph`

## Request

- Base URL: `https://apihub.co.il`
- URL: `https://apihub.co.il/v1/effects/icon-morph`
- Auth: HTTP bearer

One line icon flows into the next — chart into timeline into chat — on a tile or on its own.

אייקון קו אחד זורם לתוך הבא — גרף לציר זמן לבועת צ׳אט — על אריח או לבד.

One effect, one render: send the video (or nothing, for the canvas), the effect's `params` and when it plays (`start` + `duration` seconds, or `at` / `during` words) — every field has a default. The same effect stacks with others in `effects` of POST /v1/studio/edit. Preview: GET /v1/effects/icon-morph.

**Billing:** Per second of output, like /v1/studio/edit — the effect is burned into the same render (+ transcription seconds when a captions effect transcribes automatically). A heavy effect (one that adds render time — measured) adds effect seconds: the seconds it is on screen × its weight, priced like output seconds; GET /v1/effects/{id} states its weight and price. Failed renders are not charged. · **Rate limit:** 30/min · **Asynchronous**

## Headers

- `Idempotency-Key` string
- `X-Tag` string
- `x-wait-ms` integer

## Request body

- object
  - `at` object: Start at a word (instead of a time)
    - `edge` 'start' | 'end', required: The moment the word starts, or the moment it ends
    - `word` string, required: The word's id (w0001…)
    - `offset_ms` number: Shift in ms, applied after the cuts (default 0)
  - `keep` object[]: Keep only these spans of the video (seconds) — every join between them is a cut a transition plays on
    - `end` number, required
    - `start` number, required
  - `trim` object: Use only this part of the video (seconds)
    - `end` number
    - `start` number
  - `start` number: seconds on the output — when it starts (default: the effect's own)
  - `words` object[]: Your own timed words (ms) instead of a transcript
    - `id` string
    - `end` number, required
    - `text` string, required

    - `fps` number
    - `format` 'mp4' | 'webm' | 'mov' | 'gif' | 'mp3' | 'wav' | 'm4a' | 'jpg' | 'png'
    - `quality` 'draft' | 'standard' | 'high': high (default) = best picture; draft renders fastest for previews
    - `background` string: Bar colour for fit=pad
    - `resolution` '480' | '720' | '1080' | 'source': Short side in pixels (1080 = Full HD). `source` keeps the input size, max 1080
    - `aspect_ratio` 'original' | '9:16' | '16:9' | '1:1' | '4:5' | '4:3': 9:16 for Reels/TikTok/Shorts, 1:1 or 4:5 for feed, 16:9 for YouTube
  - `params` object: The effect's own settings (every field has a default)
    - `x` number: Centre, % from the left
    - `y` number: Centre, % from the top
    - `ms` integer: How long each change takes, ms
    - `glow` number: A soft glow round the lines, px at 1080 wide (0 = none)
    - `mode` 'cross-scale' | 'morph': cross-scale = the old one shrinks away as the new one grows from the same centre · morph = every line flows into the next
    - `size` number: Size, % of the frame width
    - `tile` boolean: On a rounded tile

    - `stroke` number: Line weight in the icon's 24-unit grid (2 = a standard outline icon)
    - `backdrop` 'none' | 'panel' | 'full': A dark motion-graphics plate behind the icons: a panel across the top, the whole frame, or none (over the video)
    - `tile_color` string: The tile
    - `stroke_color` string: The line colour
    - `backdrop_height` number: panel: its height, % of the frame
