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.
`image_url` required	URL or file	—	URL of the input 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.
