client = NexaAPI(api_key='YOUR_API_KEY')

response = client.video.generate(

    prompt='A cinematic drone shot over a misty mountain range at golden hour, 4K quality',
    duration=5,
    aspect_ratio='16:9',
    motion_control='smooth',
    quality='cinematic'
)

print(f'Video URL: {response.video_url}')
print(f'Generation time: {response.generation_time}s')
