# Walkthrough: VEO_3.1_CINEMATIC_MASTER_PROTOCOLS

I have successfully researched and implemented the requested cinematic protocols for Veo 3.1.

## Accomplishments

### 1. Research & Documentation
- **One-Shot Narrative Control**: Investigated "Start & End Frame" control for seamless 1080p narrative arcs.
- **The Trinity Rule**: Defined the best practices for using 1-3 reference images (Character, Environment, Style) to lock identity.
- **Native Audio-Context Sync**: Developed prompting strategies for synchronized dialogue and ambient sound.
- **Cinematic Skeleton Structuring**: Compared Paragraph vs. JSON architectures for lens and lighting control.

### 2. Deliverables
- Created the **[Cinematographer's Handbook](file:///C:/Users/P3/.gemini/antigravity/brain/f1af4dd1-ed91-4185-b3d8-1f28e18a99a9/cinematographers_handbook.md)** containing 5 reusable "One-Shot" meta-patterns.
- Updated the **[veo_generator.py](file:///e:/genesis-system/skills/veo_generator.py)** skill to support advanced inputs.

## Verified Changes

### Cinematographer's Handbook
The handbook defines the "Sovereign Quality" standards for Genesis video generation.

### Veo Generator Updates
I've modified `veo_generator.py` to allow passing `first_frame`, `last_frame`, and `reference_images`.

```python
    def generate(self,
                 prompt: str,
                 negative_prompt: Optional[str] = None,
                 first_frame: Optional[bytes] = None,
                 last_frame: Optional[bytes] = None,
                 reference_images: Optional[List[bytes]] = None,
                 ...
```

## Verification Results
- **API Adherence**: Parameters align with Google's latest Veo 3.1 technical documentation as research.
- **Code Integrity**: `python e:/genesis-system/skills/veo_generator.py --test` passes initialization.
