Input

Field	Kind	Default	Description
`prompt` required	text	—	The text prompt to guide video generation.
`negative_prompt`	text		Negative prompt for video generation.
`num_frames`	number (whole) 17 to 161	81	Number of frames to generate. Must be between 17 to 161 (inclusive).
`frames_per_second`	number (whole) 4 to 60	24	Frames per second of the generated video. Must be between 4 to 60. When using interpolation and `adjust_fps_for_interpolation` is set to true (default true,) the final FPS will be multiplied by the number of interpolated frames plus one. For example, if the generated frames per second is 16 and the number of interpolated frames is 1, the final frames per second will be 32. If `adjust_fps_for_interpolation` is set to false, this value will be used as-is.
`seed`	number (whole)	—	Random seed for reproducibility. If None, a random seed is chosen.
`resolution`	one of 580p, 720p	720p	Resolution of the generated video (580p or 720p).
`aspect_ratio`	one of 16:9, 9:16, 1:1	16:9	Aspect ratio of the generated video (16:9 or 9:16).
`num_inference_steps`	number (whole) 2 to 50	40	Number of inference steps for sampling. Higher values give better quality but take longer.
`enable_prompt_expansion`	true or false	false	Whether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning.
`guidance_scale`	number 1 to 10	3.5	Classifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality.
`shift`	number 1 to 10	5	Shift value for the video. Must be between 1.0 and 10.0.
`interpolator_model`	one of none, film, rife	film	The model to use for frame interpolation. If None, no interpolation is applied.
`num_interpolated_frames`	number (whole) 0 to 4	0	Number of frames to interpolate between each pair of generated frames. Must be between 0 and 4.
`adjust_fps_for_interpolation`	true or false	true	If true, the number of frames per second will be multiplied by the number of interpolated frames plus one. For example, if the generated frames per second is 16 and the number of interpolated frames is 1, the final frames per second will be 32. If false, the passed frames per second will be used as-is.
`video_quality`	one of low, medium, high, maximum	high	The quality of the output video. Higher quality means better visual quality but larger file size.
`video_write_mode`	one of fast, balanced, small	balanced	The write mode of the output video. Faster write mode means faster results but larger file size, balanced write mode is a good compromise between speed and quality, and small write mode is the slowest but produces the smallest file size.
