“KEYFRAME”是使用 FontVibe AI 创作的全息文字效果。圆润的无衬线字母，镭射箔面在紫、青、粉、金之间变幻，深色地面上有亮面倒影和细小光点。

rendered with iridescent holographic foil effect — multi-layer diffractive film surface producing rainbow spectral shifts across the letter faces, cycling through deep violet, electric cyan, hot pink to warm gold as viewing angle changes, like light diffracting through a stacked polymer security foil. The color shift is the result of structural interference, not pigment: each hue blooms and fades with directional light. Semi-transparent depth visible through the letter surface — background bleeds through with slight chromatic distortion. At all letter edges, rainbow chromatic fringe dissolves outward into scattered prismatic light particles, softening the hard boundary between letterform and space. Fine diffraction grating micro-texture across the surface. Pure black background. Directional overhead light source. Pure black studio void with the rendered text “KEYFRAME” as the sole dominant visual element, its faces clad in multi-layer iridescent holographic security foil. Structural-interference color bands travel across the surface in deep violet, electric cyan, hot pink, and warm gold, with each hue blooming along directional reflections rather than flat pigment. Fine diffraction-grating microtexture is visible over every letter face, interrupted by narrow mirror-bright specular streaks from a cold directional overhead light. Semi-transparent foil depth allows faint black-space bleed-through within the material, warped by subtle cyan-magenta chromatic distortion. Every outer edge breaks into delicate rainbow fringe, dispersing into suspended prismatic light particles and tiny spectral shards that fade quickly into the black field. Restrained soft contact shadow and a faint reflected spectral haze beneath the text establish depth without adding scenery. High-resolution product-render precision, ray-traced reflections, sharp foil detail, controlled black negative space, no extra words, no symbols, no background objects.
