Input

Field	Kind	Default	Description
`prompt` required	text	—	The text prompt to guide video generation.
`negative_prompt`	text	bright colors, overexposed, static, blurred details, subtitles, style, artwork, painting, picture, still, overall gray, worst quality, low quality, JPEG compression residue, ugly, incomplete, extra fingers, poorly drawn hands, poorly drawn faces, deformed, disfigured, malformed limbs, fused fingers, still picture, cluttered background, three legs, many people in the background, walking backwards	Negative prompt for video generation.
`start_image_url` required	URL or file	—	URL of the starting image. If the input image does not match the chosen aspect ratio, it is resized and center cropped.
`end_image_url` required	URL or file	—	URL of the ending image. If the input image does not match the chosen aspect ratio, it is resized and center cropped.
`num_frames`	number (whole) 81 to 100	81	Number of frames to generate. Must be between 81 to 100 (inclusive). If the number of frames is greater than 81, the video will be generated with 1.25x more billing units.
`frames_per_second`	number (whole) 5 to 24	16	Frames per second of the generated video. Must be between 5 to 24.
`seed`	number (whole)	—	Random seed for reproducibility. If None, a random seed is chosen.
`resolution`	one of 480p, 720p	720p	Resolution of the generated video (480p or 720p). 480p is 0.5 billing units, and 720p is 1 billing unit.
`num_inference_steps`	number (whole) 2 to 40	30	Number of inference steps for sampling. Higher values give better quality but take longer.
`guide_scale`	number 1 to 10	5	Classifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality.
`shift`	number 1 to 10	5	Shift parameter for video generation.
`enable_prompt_expansion`	true or false	false	Whether to enable prompt expansion.
`acceleration`	one of none, regular	regular	Acceleration level to use. The more acceleration, the faster the generation, but with lower quality. The recommended value is 'regular'.
`aspect_ratio`	one of auto, 16:9, 9:16, 1:1	auto	Aspect ratio of the generated video. If 'auto', the aspect ratio will be determined automatically based on the input image.
`loras`	JSON	[]	LoRA weights to be used in the inference.
