Generate a 3-second cinematic 3D video in a deep black space. Cubes and background are black; cubes are a mix of matte black cubes and blue-tinted glass cubes with subtle blue refraction. Soft faint blue rim lighting, premium corporate tech mood, clean sharp cube geometry, shallow depth of field.

Camera (0–3s):

Camera moves slowly forward while naturally weaving between cubes (gentle S-curve path), smooth parallax, no shake, no motion blur.

Cube surface details (0–3s):

All cubes EXCEPT one “hero” cube have simple internet-related icons engraved as subtle debossed (intaglio) marks: cloud, desktop, AI, server (minimal line icons or symbols). Each applicable cube shows icons on 2–3 different faces, with exactly 1 icon per face. Engravings are shallow, clean, centered, monochrome (no color fill), and only revealed by the faint blue rim light and reflect,

Cubes (0–3s):

All cubes have extremely subtle rotation. During the last part of the shot, cubes begin to exit the frame one by one, moving outward. Their speed gradually accelerates and they may do a controlled slight rotation while leaving. By the end of this 3-second shot, the scene is transitioning toward leaving fewer cubes (but do not abruptly jump; keep it natural).

Fade / Lighting (0–4s):

The environment gradually fades to darker: surrounding area and non-center cubes softly dim / vignette-like fade-out, while the center glowing cube remains readable and dominant. No new lights, no new objects, no particles, no extra effects.

Negative / Avoid

no fog, no haze, no particles, no sparks, no stars, no neon cyberpunk, no bright background, no warped cubes, no deformation, no camera shake, no motion blur, no text overlay, no watermark
