20-second deterministic motion design explainer for a product story

Opus 5.5 is absolutely cracked at motion design this entire video is code 0 After Effects 0 manual animation I showed it one viral motion post and said: “explain MakerMap, but make it insane” it came back with 20 seconds of one shape morphing through the entire product: sign up → your pin → 3,393 real makers lighting up the globe → matches → a meetup → search the crazy part? the entire animation is deterministic math the springs, cursor, morphs and motion blur are all generated inside one HTML file here’s the prompt structure steal it ↓ <inputs> Ask me for: • my product + URL • 8–12 UI states that tell its story • the real data shown in each state • brand colors + fonts + accent color • required formats (1:1, 16:9, 9:16) </inputs> <rules> One HTML file. One canvas One draw(t) function No CSS transitions No timers No state carried between frames One shape, never cut Every state is the same element changing size, radius and color while the content swaps A cursor drives the sequence with real clicks, typing and one drag Real UI. Real data. No placeholders. </rules> <structure> 120 BPM grid Something happens on every bea logo → button → handle field → “is this you?” → loader → pin → globe filling with users → matches → tabs → RSVP → search → logo </structure> <motion> Closed-form springs everywhere with only a tiny overshoot. If a value changes target multiple times, sum one spring per change Content enters after its container starts morphing and leaves before the next morph so text never overlaps Use a short blur on transitions Never fade black directly into the accent color. Move an accent element between states instead Make tab indicators stretch by putting each edge on a different spring Zoom the camera so every state fills the frame Make the last frame equal the first so the whole thing loops </motion> <export> First render one frame per beat as a contact sheet Fix anything cramped or broken Then render every frame in headless Chrome at 60fps, averaging 6 subframes for motion blur Pipe into ffmpeg: H.264 + yuv420p Export all aspect ratios in parallel </export> motion design is becoming a prompt
