Sample Code
import time
from google import genai
from google.genai import types
client = genai.Client()
operation = client.models.generate_videos(
model="veo-3.0-generate-preview",
prompt="A golden retriever playing in a sunflower field, close-up shot",
config=types.GenerateVideosConfig(
negative_prompt="barking, woof woof",
),
)
# Wait for the video generation to complete
while not operation.done:
time.sleep(20)
operation = client.operations.get(operation)
generated_video = operation.result.generated_videos[0]
client.files.download(file=generated_video.video)
generated_video.video.save("veo3_video.mp4")
