Word carousel · מילה מתחלפת

One word of a sentence keeps swapping — “we build apps → sites → bots” — sliding through its slot.

מילה אחת במשפט מתחלפת שוב ושוב — ״אנחנו בונים אפליקציות ← אתרים ← בוטים״ — מחליקה דרך המקום שלה.

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/word-carousel.

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
