URL of the input video.

The text prompt to guide video generation.

Strength of the video transformation. A value of 1.0 means the output will be completely based on the prompt, while a value of 0.0 means the output will be identical to the input video.

Number of frames to generate. Must be between 17 to 161 (inclusive).

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.

Negative prompt for video generation.

Random seed for reproducibility. If None, a random seed is chosen.

Resolution of the generated video (480p, 580p, or 720p).

Options: 480p, 580p, 720p

Aspect ratio of the generated video. If 'auto', the aspect ratio will be determined automatically based on the input video.

Options: auto, 16:9, 9:16, 1:1

Number of inference steps for sampling. Higher values give better quality but take longer.

If set to true, input data will be checked for safety before processing. Disabling it requires account authorization; unauthorized requests are always checked.

If set to true, output video will be checked for safety after generation.

Whether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning.

Acceleration level to use. The more acceleration, the faster the generation, but with lower quality. The recommended value is 'regular'.

Options: none, regular

Classifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality.

Guidance scale for the second stage of the model. This is used to control the adherence to the prompt in the second stage of the model.

Shift value for the video. Must be between 1.0 and 10.0.

The model to use for frame interpolation. If None, no interpolation is applied.

Options: none, film, rife

Number of frames to interpolate between each pair of generated frames. Must be between 0 and 4.

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.

The quality of the output video. Higher quality means better visual quality but larger file size.

Options: low, medium, high

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.

Options: fast, balanced, small

If true, the video will be resampled to the passed frames per second. If false, the video will not be resampled.
