```

## Important Notes

- The `ATLASCLOUD_API_KEY` environment variable must be set
- Image-to-video mode (`--mode i2v`) requires `--image` flag with a valid file path
- Video generation takes 1-5 minutes depending on model, duration, and settings
- Supported durations: 5, 10, or 15 seconds (varies by model)
- Supported resolutions: 360p, 480p, 720p, 1080p
- Output files are saved as `.mp4`
- Use `--seed` for reproducible results across identical prompts
- For vertical video (e.g., mobile/social), use `--aspect-ratio 9:16`
- Native audio generation works best with scenes that have natural sound elements
