What problem does it solve? Developers working with Remotion (programmatic video creation in React) often lack domain-specific guidance on compositions, animations, media assets, and captions, leading to incorrect implementations and wasted debugging time. ## Core Features & Use Cases - Composition & Structure Rules: Guidance on defining compositions, dynamic metadata calculation, and parametrizing videos with Zod schemas. - Media & Animation Patterns: Best practices for images, videos, audio, fonts, GIFs, Lottie, 3D with Three.js, transitions, sequencing, and text animations. - Captions & Utilities: Instructions for importing SRT subtitles, transcribing audio, displaying TikTok-style captions, and using Mediabunny utilities like extracting frames or reading video duration. - Use Case: When building a video that displays animated captions synced to audio, consult the caption and timing rules to implement word highlighting and sequencing correctly. ## Quick Start Ask the AI to apply the Remotion best practices rules when writing or reviewing Remotion video code in your project.
