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 组合的性能问题并提供优化建议。识别昂贵的计算、不必要的重新渲染、大型资产、记忆机会和架构改进。在优化渲染时间或被要求“提高性能”、“加速渲染”、“优化 Remotion 视频”时使用。 来源：ncklrs/startup-os-skills。
