TechHalla 20 秒动态品牌片头

English prompt

You are a world-class motion designer doing a 20.00s kinetic identity bumper for TechHalla — an AI creator known for stealable workflows, not vibes. This piece must feel like the best designer in the room made a street-poster that moves. Showreel stakes: if this is weak, you don’t get hired. DURATION: exactly 20.00 seconds. LOOPABLE: frame 0 == frame last (position, opacity, cursor if any). FORMAT: one HTML file, 1080×1080 (square, X-native). 60fps. PALETTE (strict): - bg # 0A0A0A - magenta # FF2BD6 - acid green # B8FF00 - white # F5F5F5 only for primary readable type when needed No other hues. No gradients on UI chrome. Magenta/green may misregister (print offset) by 2–4px on impact frames only. TYPE SYSTEM (use all three; never one font for everything): 1) Display / scream: Archivo Black (or equivalent ultra-condensed black) — 1–4 words max 2) Urban grotesque: Syne ExtraBold — secondary hits, stacked lines 3) Mono / “prompt code”: IBM Plex Mono Medium — small labels, timestamps, fake prompt crumbs Tracking: display −40 to −80; mono +20. Optical kerning. No cute script fonts. MESSAGE (locked — do not soften, do not add filler slogans): Beat hits in this exact order: 1. STOP SCROLLING 2. AI VIDEO ISN’T EXPENSIVE 3. BAD PROMPTING IS 4. WORKFLOWS > WISHES 5. STEAL THE PROMPT 6. @ TECHHALLA Supporting crumbs (mono, ≤18 chars, never full sentences): JSON · H3 · SEEDANCE · 0 KEYFRAMES · MAGNIFIC · COPY/PASTE NARRATIVE ARC (20s): 0.0–2.5s COLD OPEN — “STOP SCROLLING” slams in from below with spring overshoot; magenta smear trail; acid green baseline ticks across like a waveform. 2.5–6.5s THESIS A — “AI VIDEO ISN’T EXPENSIVE” locks to a poster grid (baseline grid 8px). Letters scramble (seeded Fisher–Yates per glyph) then snap on the beat. 6.5–10.5s THESIS B — “BAD PROMPTING IS” replaces it via mask wipe through the letterforms (the outgoing line is the mask). Magenta/green channel split on the cut. 10.5–14.5s PROOF FLASH — rapid kinetic stack: WORKFLOWS > WISHES, then mono crumbs orbit a central block like a terminal. One fake “prompt block” types 3 lines max, then gets crossed by an acid green strikethrough that becomes a underline for STEAL THE PROMPT. 14.5–17.5s BRAND LOCK — @ TECHHALLA centers; display weight. A thick magenta bar and a thin acid green rule form an L-bracket mark (custom, not a logo download). 17.5–20.0s SETTLE / LOOP — hold lockup; micro-breath (scale 1.000→1.012→1.000); last frame == first ready for loop. CONCRETE TECHNIQUES (required — implement, don’t approximate): 1. seek(t) pure function of time. No CSS transitions. No setInterval. No React state across frames. 2. Springs = closed-form step responses. Stack one spring per target change so motion stays deterministic. 3. Kinetic type: per-glyph spring (y, opacity, blur). Stagger = 1/16 note at 120 BPM (125ms). 4. Print misregistration: on accent frames only, duplicate text layer offset (±2–4px) in magenta and acid green at 40% opacity. 5. Mask reveal: destination text revealed by animating a path mask derived from the outgoing word’s outlines. 6. Camera: one orthographic camera; only punch-in (1.0→1.08) and horizontal smash-pans timed to beats — never random drift. 7. Motion blur: render 4 subframes per frame, blend (tmix-style). 8. Beat grid: 120 BPM, downbeat at t=0. Something must land on every beat for the first 16 beats; after that, every other beat is ok. 9. Pre-pass: before full render, export one still per major beat (8 frames). Fix cramped type, orphan words, low contrast — then render. BANNED: Generic AI clichés (brains, robots, neural nets, sparkles), soft gradients, bouncy cartoon easing, particle explosions, stock “futuristic HUD”, long paragraphs, narrator essay energy, Canva-deck energy, extra slogans beyond the locked message, purple/blue neon, glassmorphism.
