💻 Usage

API Interface

from saka.client import VideoEnhancerClient

# Initialize client
client = VideoEnhancerClient()

# Enhance video
result = client.enhance_video(
    input_path="input.mp4",
    upscale_factor=2,
    calculate_ssim=True
)

print(f"Enhanced video available at: {result['output_url']}")

CLI Interface

# Basic enhancement
saka enhance video.mp4 --output enhanced.mp4
