Submit the request with `VIDGO_API_KEY`. A `task_id` is returned immediately. Keep it until the task reaches `finished` or `failed`. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. If you provide a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task finishes or fails. # Kling 3.0 4K Image to Video Animate image references with Kling 3.0 4K, with support for multiple shots, individual shot prompts, and optional sound. ## Available Models * **kwaivgi/kling-v3.0-4k/image-to-video** - Generate video from image input. ## Duration Options * **3-15 seconds** - Set `duration` as an integer. Required. * With `multi_prompt`, the shot durations must add up to the requested `duration`. ## Key Features * Generate video from image input. * Provide 1–2 images in `image_urls`. * Describe individual shots with `multi_prompt` and enable `multi_shots`. * Supply additional subject references through `kling_elements`. ## Advanced Parameters Set `model` and optional `callback_url` at the request root. Place all workflow parameters, including output options, inside `input`. Use the input fields listed below. Send durations as JSON integers and switches as JSON booleans. Use public HTTP(S) media URLs with a hostname and URL-based access. * Each `multi_prompt` shot requires a nonblank `prompt` and an integer `duration` from **1 to 12 seconds**. * The shot durations must sum to the requested `duration`. Set `multi_shots: true` and `sound: true` when using `multi_prompt`. * When supplying `kling_elements`, provide `image_urls` and reference the element by `@element_name` in the prompt. ### Image URLs * `image_urls`: Required. Provide publicly accessible image URLs. Supply 1–2 items: the start frame first, followed by an optional end frame. Each item must be an HTTP(S) URL. ### Prompt * `prompt`: Required when `multi_shots` is `false`. Describe the scene and desired motion. Length: **1-2,500 characters**. * Use nonblank text for each prompt. ### Multi-Prompt * `multi_prompt`: Required when `multi_shots` is `true`. Supply a nonempty array. Each item is an object. * `multi_prompt[].prompt`: Required. Maximum length: **2,500 characters**. * `multi_prompt[].duration`: Required. Duration in seconds. Integer from `1` to `12`. * Each shot duration is measured in seconds. ### Multi-Shot Generation * `multi_shots`: Optional. Enable multi-shot generation. Use `true` or `false`. Default: `false`. ### Sound * `sound`: Required. Set `true` to generate audio or `false` for a silent single shot. Multiple shots require `true`. ### Kling Elements * `kling_elements`: Optional. Provide element-reference objects. Supply an array. Each item is an object. * Element object properties are preserved in the submitted request. ## OpenAPI ````yaml api-manual/video-series/kwaivgi-kling-v3-0-4k-image-to-video.json POST /api/generate/submit openapi: 3.0.0 info: title: Vidgo API - Kling 3.0 4K Image to Video description: >- Animate image references with Kling 3.0 4K, with support for multiple shots, individual shot prompts, and optional sound. version: 1.0.0 servers: - url: https://api.vidgo.ai security: - BearerAuth: [] paths: /api/generate/submit: post: tags: - Video Series summary: Kling 3.0 4K Image to Video description: >- Generate a single shot with prompt or a sequence with multi_prompt.
