Comprehensive performance analysis and optimization recommendations for Remotion video compositions. Identifies bottlenecks and provides actionable fixes to reduce render times.

// ❌ PROBLEM: Math.random() called 70 times per frame {Array.from({ length: 70 }, (, i) => { const x = Math.random() width; // Recalculated every frame! const y = Math.random() height; // Non-deterministic const speed = Math.random() 2;

// ✅ OPTIMIZED: Seeded random, deterministic const seededRandom = (seed: number): number => { const x = Math.sin(seed) 10000; return x - Math.floor(x); };

分析 Remotion 組合的性能問題並提供優化建議。識別昂貴的計算、不必要的重新渲染、大型資產、記憶機會和架構改進。在優化渲染時間或被要求“提高性能”、“加速渲染”、“優化 Remotion 視頻”時使用。 來源：ncklrs/startup-os-skills。
