API Parameters

Technical specifications for API request parameters.

Field Name	Parameter	Technical Description
Image URL	`init_image`	Image to be used as the first frame of the video in either an HTTPS URL format or base64 data URI format.
Prompt	`prompt`	Text description of how the image should be animated, can relate to the details in the image
Resolution	`resolution`	Output video resolution: Supported resolutions include 1920×1080, 2560×1440, and 3840×2160.
Duration	`duration`	Video duration (in seconds): Supported durations depend on the model and include 6s, 8s, and 10s.
Generate audio	`generate_audio`	Generate audio for the video. When true, the generated video will include AI-generated audio matching the scene. When false, only silent video is generated.
FPS	`fps`	Frame rate (frames per second): Supported frame rates depend on the model and resolution, with available options 25 FPS and 50 FPS. This parameter is optional and defaults to 25 FPS.
model_id	`model_id`	Model selection: Specify the model to use for generation, such as ltx-2-pro-i2v.
