prompt

string

Describe what to generate, or the change to make.

negative_prompt

string

What to keep out of the result.

aspect_ratio

enumdefault LANDSCAPE_16_9_480pLANDSCAPE_16_9_480p, PORTRAIT_9_16_480p

The shape and size of the output.

prompt_enhancement

enumdefault AUTOAUTO, OFF, STANDARD

Let the model rewrite the prompt before generating.

seed

integer

The starting point for the model's randomness. The same seed and settings give the same result.

inference_steps

integerdefault 281–50

How many refinement passes the model makes. More add detail and take longer.

duration_seconds

integerdefault 5

Length of the generated clip, in seconds.

guidance_file_first_frame

file[]required

The frame the video starts on

prompt_language

string

The language the prompt is written in, so it reaches the model as you meant it.
