<title>Scene 01 — Counting Icon Burst</title>
|
||
|
||
<!--
|
||
HyperFrames composition.tsx.
|
||
|
||
Choreography (4 phases, 3.5 seconds total):
|
||
0.00 – 0.17s Background visible with dark overlay; nothing else
|
||
0.17 – 0.57s Four enriched icons enter staggered, clustered at startOffset 0.4
|
||
(clock 0.17s · scissors 0.30s · video 0.43s · play 0.57s)
|
||
0.47 – 1.47s Counter "0 → 90" with growing font size (0.20W → 0.42W);
|
||
icons expand outward from 40% to 100% position
|
||
0.50 – 2.33s Camera focus phase: scale 0.92 → 1.0
|
||
2.33 – 3.50s Camera push phase: scale 1.0 → 1.08
|
||
1.27s Percent symbol pops in with own spring
|
||
|
||
Continuous motion (running from t=0, gated by icon visibility):
|
||
Clock minute hand: linear rotation 420° over 3.5s
|
||
Scissors: ±15° sine oscillation, period ~1.7s
|
||
Cutting line: stroke-dashoffset drifts -200 over 3.5s
|
||
Video record dot: opacity + scale phase-offset sine pulses
|
||
Play triangle: scale pulse ±8%, period ~2.6s
|
||
ease + duration (no shared driver needed, just identical timing)
|
||
- Counter text + number scale are emitted as seek-safe timeline keyframes
|
||
- Background: local Pexels MP4 plus dark overlay
|
||
- Per-icon entry uses GSAP fromTo on a nested .icon-entry wrapper
|
||
so it never overwrites the .icon-pos expansion tween
