See the input and output schema below, as well as the usage examples. ### Input Schema The API accepts the following input parameters: - **`prompt`** (`string`, _optional_): Text prompt for video generation. Either prompt or multi_prompt must be provided, but not both. - Examples: "Cinematic drone shot flying through ancient stone ruins covered in moss and vines at golden hour. Camera starts low, rises through crumbling archways, revealing a vast misty valley beyond. Volumetric light rays pierce through gaps in the stone. Epic scale, photorealistic, 8K quality." - **`duration`** (`DurationEnum`, _optional_): The duration of the generated video in seconds Default value: `"5"` - Default: `"5"` - Options: `"3"`, `"4"`, `"5"`, `"6"`, `"7"`, `"8"`, `"9"`, `"10"`, `"11"`, `"12"`, `"13"`, `"14"`, `"15"` - **`multi_prompt`** (`list`, _optional_): List of prompts for multi-shot video generation. If provided, overrides the single prompt and divides the video into multiple shots with specified prompts and durations. - Array of KlingV3MultiPromptElement - Examples: null - **`generate_audio`** (`boolean`, _optional_): Whether to generate native audio for the video. Supports Chinese and English voice output. Other languages are automatically translated to English. For English speech, use lowercase letters; for acronyms or proper nouns, use uppercase. Default value: `true` - Default: `true` - **`voice_ids`** (`list`, _optional_): Optional Voice IDs for video generation. Reference voices in your prompt with <<>> and <<>> (maximum 2 voices per task). Get voice IDs from the kling video create-voice endpoint: https://fal.ai/models/fal-ai/kling-video/create-voice - Array of string - **`shot_type`** (`ShotTypeEnum`, _optional_): The type of multi-shot video generation Default value: `"customize"` - Default: `"customize"` - Options: `"customize"`, `"intelligent"` - **`aspect_ratio`** (`AspectRatioEnum`, _optional_): The aspect ratio of the generated video frame Default value: `"16:9"` - Default: `"16:9"` - Options: `"16:9"`, `"9:16"`, `"1:1"` - **`negative_prompt`** (`string`, _optional_): Default value: `"blur, distort, and low quality"` - Default: `"blur, distort, and low quality"` - **`cfg_scale`** (`float`, _optional_): The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt. Default value: `0.5` - Default: `0.5` - Range: `0` to `1` **Required Parameters Example**: ```json {} ``` **Full Example**: ```json { "prompt": "Cinematic drone shot flying through ancient stone ruins covered in moss and vines at golden hour. Camera starts low, rises through crumbling archways, revealing a vast misty valley beyond. Volumetric light rays pierce through gaps in the stone.
