Request body

8 properties · 1 required · 1 $defs
propertytypedescriptionconstraints
prompt*stringThe prompt to use as a starting point for the generation.
enable_safety_checkerbooleanAuthorized callers may set false to request relaxed screening.default: true
stepsintegerThe number of steps to run the model for. The higher the number the better the quality and longer it will take to generate.1 ≤ n ≤ 20 · default: 4
cond_augnumberThe conditoning augmentation determines the amount of noise that will be added to the conditioning frame. The higher the number, the more noise there will be, and the less the video will look like the initial image. Increase it for more motion.0 ≤ n ≤ 10 · default: 0.02
fpsintegerThe FPS of the generated video. The higher the number, the faster the video will play. Total video length is 25 frames.1 ≤ n ≤ 25 · default: 10
motion_bucket_idintegerThe motion bucket id determines the motion of the generated video. The higher the number, the more motion there will be.1 ≤ n ≤ 255 · default: 127
seedinteger The same seed and the same prompt given to the same version of Stable Diffusion will output the same image every time. nullable
video_sizeImageSize | enumThe size of the generated video.default: "landscape_16_9"

Types
