Request Parameters - Image To Video Request

Field Type Required Default Description
model enum string Yes — The image-to-video model to use for generation. Available options: dop-lite, dop-preview, dop-turbo. Each model offers different quality and speed trade-offs. Example: dop-lite
prompt string Yes — Text description/prompt for video generation. Describes the desired video content, style, and motion. Be descriptive for better results. Example: A peaceful sunset over mountains with clouds moving slowly
seed integer Yes — Random seed for reproducible results. Must be between 1 and 1,000,000. Using the same seed with identical parameters will produce similar results. Example: 500000
motions_id string (UUID) Yes — Unique identifier for the motion preset. This ID corresponds to predefined motion effects available in the system. You can get motion_id using the API: https://endpoints.appypie.com/api-details#api=ai-model-api-polling&operation=motions
motions_strength number (0-1) Yes — Intensity of the motion effect application. Range from 0.0 (minimal effect) to 1.0 (maximum effect) with 0.01 step precision. Higher values create more pronounced motion. Example: 0.75
input_images array of strings Yes — Array of image URLs for video generation. Each URL must be a publicly accessible link pointing to a valid image file. Supported formats include JPEG, PNG, WebP. Must contain exactly 1 element for standard generation. Example: ["https://example.com/image1.jpg"]
input_images_end array of strings No null Array of end frame image URLs for Start & End Frame functionality. Each URL must be a publicly accessible link pointing to a valid image file. Supported formats include JPEG, PNG, WebP. Minimum length: 1 element. Enables advanced frame interpolation between start and end images. Example: ["https://example.com/end-frame.jpg"]
enhance_prompt boolean Yes — Whether to automatically enhance and refine the provided prompt. When true, the system will optimize your prompt for better video generation results. Example: true
check_nsfw boolean No true Whether to perform NSFW (Not Safe For Work) content detection. When true, the system will check for inappropriate content and may reject the request if detected.
