Cinematic looping banner video, 16:9, 5 seconds, seamless loop where
the final frame matches the first frame exactly.
SCENE (static composition, locked-off camera, no pan no zoom):
Left third: a glowing diamond-cracked glass card icon — a frosted
square with a 45° diagonal split, two halves slightly separated, a
rounded crimson diamond (#FF0044) suspended in the gap. Right
two-thirds: empty negative space, deep matte black with faint
horizontal crimson haze fading right. Faint dot grid covering the
entire background. Single dramatic side light from upper-left,
cinematic shadows.
LOOPING MOTION (must return to start state by frame end):
1. HEARTBEAT PULSE on the central crimson diamond — lub-dub rhythm,
two pulses per loop: at 0.4s a quick scale to 108% with red glow
intensifying, snap back to 100%, then at 1.2s a softer pulse to
105%, back to 100%, then rest. Repeat the same lub-dub at 3.0s
and 3.8s. End frame matches start: diamond at 100% scale, glow
at base level.
2. GLASS HALVES — the two split halves breathe apart and back:
gradually drift outward by 2px each over 2.5s, then drift back
together over 2.5s, returning to exact starting position.
3. RED LIGHT LEAK from the diagonal crack — volumetric red rays
pulse in sync with the heartbeat, brightest at the lub-dub peaks,
softest at rest. Rays loop smoothly, no flicker.
4. ATMOSPHERIC HAZE — the crimson haze on the right side gently
breathes (subtle opacity shift 80%→100%→80%) once across the
full 5 seconds, ending at the same opacity it started.
5. DUST PARTICLES — a few sparse dust motes drift very slowly
upward and across, but they fade in at 0% opacity at start,
fade out to 0% at end, so the particle field is empty at both
bookend frames (invisible particles = matching frames).
6. CAMERA — completely locked, no movement. Background grid stays
pixel-perfect identical at frame 1 and frame final.
STYLE: premium editorial, Apple keynote aesthetic, Octane-render
quality glass refraction, 8K detail, crimson (#FF0044) is the only
saturated color, everything else is matte black / charcoal / frosted
white highlights.
LOOP REQUIREMENT: frame 1 and final frame are pixel-identical —
all moving elements (pulse scale, glass position, haze opacity,
particle opacity) must return to their exact starting values. No
fade-to-black, no cuts, no easing-in-only animations.
Negative: no text, no people, no camera movement, no zoom, no pan,
no one-way drift, no fade transitions, no extra colors, no UI
elements appearing or disappearing without returning.
