Executive Directive & The Motion Cloning Paradigm (2026 Shift)

Figma mockups and static screenshots only capture the resting state ($t = 0$) of an interface. They completely omit acceleration curves, spatial springs, gesture resistance, expansion transitions, and dynamic layout reflow. When engineers attempt to code interactions from memory or generic timing specs (ease-in-out), the resulting UI feels clunky, stiff, and disconnected.

The Multimodal Spatial Video Cloner reverse-engineers production-grade web interfaces directly from MP4/WebM screen recordings and spatial video demos. By slicing 60fps video frames, calculating optical flow vectors, extracting spring physics (stiffness, damping ratio, mass), and mapping visual geometry to Tailwind CSS v4 and Framer Motion 12+, it produces 1:1 pixel-accurate and physics-accurate implementations.

1. Mathematical Harmonic Oscillator Model

Natural human-feeling interfaces behave as damped harmonic oscillators: $$m \frac{d^2 x}{dt^2} + c \frac{dx}{dt} + k x = 0$$

• Stiffness ($k$): How aggressively the element snaps toward its target ($200 - 500$ for snappy UI).
• Damping Ratio ($\zeta$): Suppresses overshoot ($\zeta = 1.0$ is critically damped, $\zeta < 1.0$ has natural subtle bounce).
• Mass ($m$): Perceived visual weight of the container.

2. The 4 Video Extraction Rules

1. 60fps Frame Ingestion: Video clips must be analyzed at high frame rates to capture micro-stutters and easing inflection points.
2. Tabular Numerals Preservation: Ensure any rolling counters or streaming stock tickers in the recording are mapped with tabular-nums.
3. Pillar 7 Sanitation: If the source video uses generic AI tropes (e.g. pill buttons on rectangular cards), the cloner automatically normalizes them to structured rounded-xl surfaces with 1px borders.
4. Accessible Reduced-Motion Support: All generated motion components MUST wrap transitions with useReducedMotion() from Framer Motion.

Direktif Eksekutif & Paradigma Kloning Gerak (Pergeseran 2026)

Mockup desain statis atau tangkapan layar hanya menampilkan antarmuka saat diam ($t = 0$). Mereka sama sekali tidak merekam kurva akselerasi, fisika pegas, resistensi sentuhan, transisi ekspansi, dan pergeseran tata letak. Ketika pengembang membuat animasi berdasarkan perkiraan kasar (ease-in-out), antarmuka yang dihasilkan terasa kaku dan tidak alami.

Multimodal Spatial Video Cloner merekayasa balik antarmuka web langsung dari rekaman layar MP4/WebM dan video spasial. Dengan memotong frame video pada 60fps, menghitung vektor aliran optik, mengekstrak parameter fisika pegas (stiffness, damping, mass), serta memetakan tata letak ke Tailwind CSS v4 dan Framer Motion 12+, sistem ini menghasilkan kode yang presisi 1:1 terhadap rekaman aslinya.

3 Hukum Utama Rekayasa Balik Video

1. Analisis Frame 60fps: Video wajib dibedah pada frekuensi tinggi untuk menangkap titik belok akselerasi yang akurat.
2. Kepatuhan Angka Tabular (tabular-nums): Setiap angka yang berputar atau bergerak dalam rekaman wajib dikonversi dengan kelas tabular-nums.
3. Sanitasi Pilar 7: Jika rekaman sumber menggunakan desain klise (seperti tombol pil berlebih), sistem kloning otomatis menormalkannya ke wadah rounded-xl dengan border 1px yang tegas.
