API Reference

​
Input Schema

​
prompt
string
required
The text prompt describing the video you want to generate
​
aspect_ratio
AspectRatioEnum
default:"auto"
The aspect ratio of the generated video. Only 16:9 and 9:16 are supported. Default value: "auto"Possible values: auto, 16:9, 9:16
​
duration
DurationEnum
default:"8s"
The duration of the generated video. Default value: "8s"Possible values: 4s, 6s, 8s
​
negative_prompt
string
A negative prompt to guide the video generation.
​
resolution
ResolutionEnum
default:"720p"
The resolution of the generated video. Default value: "720p"Possible values: 720p, 1080p, 4k
​
generate_audio
boolean
default:"true"
Whether to generate audio for the video. Default value: true
​
seed
integer
The seed for the random number generator.
​
auto_fix
boolean
default:"false"
Whether to automatically attempt to fix prompts that fail content policy or other validation checks by rewriting them.
​
safety_tolerance
SafetyToleranceEnum
default:"4"
The safety tolerance level for content moderation. 1 is the most strict (blocks most content), 6 is the least strict. Default value: "4"Possible values: 1, 2, 3, 4, 5, 6
​
image_url
string
required
URL of the input image to animate. Should be 720p or higher resolution in 16:9 or 9:16 aspect ratio. If the image is not in 16:9 or 9:16 aspect ratio, it will be cropped to fit.
