[GAMING-000] Gaming Framework Integration - Epic #47
Description
[GAMING-000] Gaming Framework Integration - Epic
Overview
Transform Rendervid into a game engine-powered video generation platform, enabling AI agents to create game-style marketing videos with physics, particles, behaviors, and 2D/3D graphics.
Vision
Enable creation of dynamic, game-like videos that go beyond static animations:
- Products falling and bouncing with realistic physics
- Explosions, fire, and particle effects
- Cinematic post-processing (bloom, depth of field, motion blur)
- 2D platformer and arcade-style scenes
- AI-controlled behaviors and procedural generation
- Custom scripting for complex game logic

- Enable entirely new use cases
- Position Rendervid as a game engine for video
- Make it the most powerful AI video generation tool
The modular architecture ensures features can be adopted incrementally without breaking existing functionality.
