title: "Changes to Generate a short video clip from a source image and a motion text prompt (image-to-video). Synchronous until September 10, 2026: the call blocks until rendering finishes and returns the video URL and its actual duration in seconds - there is no separate polling step. Optionally pass `final_image` to interpolate between a start and end frame. The chosen `model` and `duration` must be compatible (incompatible combinations return HTTP 400); see the `model` and `duration` fields for the values each model accepts. Credits are charged only on success, based on the produced duration and never more than the duration you requested. Pass an optional `request_id` to tag the result so you can locate it later via `GET /assets/videos/results`. Related tools: use `createImage` for static images, `animateSprite` for sprite-sheet animation, and `GET /assets/videos/results` to list videos you generated earlier. Requires an API key (user scope). Async is the intended integration pattern: pass `async: true` and the call returns 202 with a job id - poll `GET /assets/jobs/{id}` (`getApiJob` in MCP), honouring poll_after_ms or long-polling with wait=30, until status is succeeded, whose result field is exactly the response documented for this operation. Synchronous responses are deprecated: they remain the default until September 10, 2026, after which requests default to async and return 202 with a job id; set `async: false` explicitly to keep synchronous behavior during and after the transition. Synchronous calls run on the same queue: the response carries an X-Ludo-Job-Id header, and a job still running after 15 minutes comes back as 202 with the job instead of an error. Each account may have up to 50 generations queued or running at once via the API; a request beyond that returns 429 (code PENDING_JOBS_LIMIT)."
