Use the Veo 3.0 video generation model to generate high-quality video content from text descriptions. This API uses asynchronous processing, and you need to query the final generation result using the task_id.

​
Request Headers

​
Content-Type
string
required
Enum value: application/json
​
Authorization
string
required
Bearer authentication format: Bearer {{API key}}.

​
Request Body

​
prompt
string
required
A text string describing the video you want to generate.
​
aspect_ratio
string
Specifies the aspect ratio of the generated video.Enum values: 16:9, 9:16. The default value is 16:9.
​
duration_seconds
integer
The length of the video file you want to generate, in seconds.Enum values: 4, 6, 8. The default value is 8.
​
enhance_prompt
boolean
Specifies whether to use Gemini to enhance your prompt.Default value: true
​
generate_audio
boolean
Specifies whether to generate audio for the video.
​
negative_prompt
string
A text string describing content you want to prevent the model from generating.
​
person_generation
string
Safety setting that controls whether people or faces are allowed to be generated.Enum values:
  • allow_adult (default): Only allows adults to be generated
  • dont_allow: Does not allow people or faces to be included in the image
  • allow_all: Allows people of all ages to be generated (requires the project to be on the allowlist)
​
resolution
string
The resolution of the generated video.Enum values: 720p (default) or 1080p
​
sample_count
integer
The number of videos to generate.Value range: 1-4
​
seed
uint32
A number used to initialize the random generation process. Using the same seed, prompt, and other parameters will produce the same output video, making the generation process deterministic.Value range: 0-4,294,967,295

​
Response Parameters

​
task_id
string
required
The task_id of the asynchronous task. You should use this task_id to request the Get Task Result API to obtain the generation result
