prompt

string

Describe what to generate, or the change to make.

color_palette

any

Colors the output should use. This model doesn't take a palette natively, so the colors are added to the prompt.

negative_prompt

string

What to keep out of the result.

aspect_ratio

enumdefault LANDSCAPE_16_9_720p6 options

The shape and size of the output.

quality

enumdefault HIGHLOW, MEDIUM, HIGH

Higher levels render more detail, and can take longer and cost more.

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 408–50

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

duration_seconds

integerdefault 5

Length of the generated clip, in seconds.

generate_audio

booleandefault false

Add sound, generated with the video in the same pass.

guidance_file_first_frame

file[]

The frame the video starts on

guidance_file_last_frame

file[]

The frame the video ends on

prompt_language

string

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