- `compression_format` - Legacy option (not sent in current API request format)
- `safety_filter_level` - Legacy option (not sent in current API request format)
- `negative_prompt` - Text describing what to avoid in the video
- `seed` - Random seed for reproducibility
- `guidance_scale` - How closely to follow the prompt (1.0-20.0)
- `person_generation` - Person generation policy (default: :dont_allow)
- `image` - Optional image input for image-to-video
- `last_frame` - Optional last frame for interpolation (Veo 3.1)
- `reference_images` - Optional list of reference images (Veo 3.1)
- `video` - Optional input video for extension (Veo 3.1)
- `resolution` - Output resolution ("720p" or "1080p")
