Topic: Rendering_System Title: Rendering System
1. Overview
The Rendering System in ACT 3 is responsible for turning creative assets — scripts, shot definitions, set configurations, and character cues — into fully realized visual outputs. This system supports automated, high-quality video rendering using cloud-based infrastructure and AI-assisted processes.
2. Key Components
2.1 Scene Compilation
- Function: Aggregates all data from the Set, Camera, Characters, Lighting, and VFX sections of the Shot YAML.
- Purpose: Ensures all inputs are validated and complete before rendering.
2.2 Frame Rendering Engine
- Function: Converts compiled scenes into image frames.
- Technology: Utilizes cloud GPU services and AI video models (like Veo 3) for photorealistic generation.
- Output: Raw frames in .png or .jpg format.
2.3 Video Stitcher
- Function: Combines rendered frames into a seamless video sequence.
- Features: Frame transition smoothing, background audio sync, title and credits overlays.
2.4 Post-Processing Module
- Function: Enhances visual output through filters, grading, and corrections.
- Customizations: LUTs, color grading profiles, camera shake simulation, focus/blur depth adjustments.
3. Workflow
- User defines a project and configures shots using the ACT 3 interface.
- System compiles all assets into a rendering-ready format.
- Rendering engine executes shot-by-shot frame generation.
- Frames are stitched and processed into final video.
- Output is stored in user-accessible media library or cloud bucket.
4. Features
- Automated Frame Rendering based on AI-driven interpretation of YAML prompt structure
- Cloud-Based Infrastructure for scalable processing
- Multi-shot Support with transition and timing control
- Custom Post-FX including mood filters, VFX overlays, and lens effects
- Model Integration: Supports tools like Google Veo 3 or Runway ML
5. Performance Considerations
| Aspect | Strategy |
|---|---|
| GPU Optimization | Uses parallel GPU pipelines for multi-shot tasks |
| Render Failures | Includes intelligent retry and fallback mechanisms |
| Output Resolution | Renders up to 4K with optional aspect ratio control |
| Credit Cost | Billed per frame or per second of video output |
6. API Integration
- POST /render/start — Starts rendering job
- GET /render/status/:id — Returns status of a render job
- GET /render/download/:id — Provides video download URL
- POST /render/cancel/:id — Cancels an in-progress job
