Request body

18 properties · 1 required · 0 $defs
propertytypedescriptionconstraints
prompt*stringThe text prompt to guide video generation.
enable_prompt_expansionbooleanWhether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning.default: false
num_interpolated_framesintegerNumber of frames to interpolate between each pair of generated frames. Must be between 0 and 4.0 ≤ n ≤ 4 · default: 0
enable_safety_checkerbooleanIf set to true, input data will be checked for safety before processing. Disabling it requires account authorization; unauthorized requests are always checked.default: false
adjust_fps_for_interpolationbooleanIf 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 p…default: true
negative_promptstringNegative prompt for video generation.default: ""
aspect_ratioenumAspect ratio of the generated video (16:9 or 9:16).16:9 | 9:16 | 1:1 · default: "16:9"
num_framesintegerNumber of frames to generate. Must be between 17 to 161 (inclusive).17 ≤ n ≤ 161 · default: 81
shiftnumberShift value for the video. Must be between 1.0 and 10.0.1 ≤ n ≤ 10 · default: 5
enable_output_safety_checkerbooleanIf set to true, output video will be checked for safety after generation.default: false
num_inference_stepsintegerNumber of inference steps for sampling. Higher values give better quality but take longer.2 ≤ n ≤ 50 · default: 40
resolutionenumResolution of the generated video (580p or 720p).580p | 720p · default: "720p"
seedintegerRandom seed for reproducibility. If None, a random seed is chosen.nullable
frames_per_secondintegerFrames 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.4 ≤ n ≤ 60 · nullable
video_qualityenumThe quality of the output video. Higher quality means better visual quality but larger file size.low | medium | high | maximum · default: "high"
interpolator_modelenumThe model to use for frame interpolation. If None, no interpolation is applied.none | film | rife · default: "film"
video_write_modeenumThe 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.fast | balanced | small · default: "balanced"
guidance_scalenumberClassifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality.1 ≤ n ≤ 10 · default: 3.5
