# Tool: Write Prompt for Runway Gen-3 Smooth Transitions

> Master seamless first-frame to last-frame morphing with the BOPINK Runway Gen-3 Transition Engine. Created for video editors, music video creators, and creative directors, this generator structures video prompts for Runway Gen-3 Alpha and Pika 2.0. It coordinates visual anchor points, environmental morphing trajectories, color palette shifts, and camera velocity vectors to execute match cuts and liquid morphs without harsh jumping artifacts.

**Category**: prompts-video | **Target AI Models**: Runway Gen-3 Alpha, Pika 2.0

## Domain Parameters:
- `transitionSpeed` (select): Morph Velocity Curve (Default: "Gradual")
- `visualAnchor` (toggle): Maintain Center-Frame Visual Anchor (Default: "true")
- `styleShift` (toggle): Artistic Texture Style Shift (Default: "")
- `negativeFilter` (toggle): Filter Transition Artifacts (Default: "true")

## Master Prompt Engineering Architecture (5 Pillars):
1. **Role & Persona**: Domain expert framing
2. **Task & Deliverable**: Primary objective & constraints
3. **Context & Parameters**: Technical specs & camera/stack parameters
4. **Negative Constraints**: Forbidden artifacts & bad practices
5. **Output Spec**: Section formatting & XML/Markdown structure
