AIプロンプト

Create a clean, silent 2D motion-graphics study of Box Reveal, in a landscape 16:9 composition.

A centered rectangle expands to cover the frame.

Timing: one complete reference cycle lasts 3.2 seconds, including the described holds and reset. If the output clip is longer, repeat this cycle. Use smooth acceleration and deceleration between the described poses, preserving the holds and corrections.
Playback order: forward, following the sequence described above.
Composition: scale the entire artwork layout to 100% of the baseline centered composition; the canvas size stays fixed. Keep the motion unclipped. Use a background #090a12 and main-color artwork #c4c5ce (pale-tint: the main color blended about 75% toward the background), crisp edges and restrained shading. Lock the camera; no camera movement, cuts, perspective changes beyond the stated technique, or extra objects.
No visible text or numbers. No logos, watermarks, interface controls or captions. No dialogue, music, sound effects or ambient audio.

Priority: preserve the defining movement — A centered rectangle expands to cover the frame. Compare the beginning, middle and end of the cycle.
Final palette: main color #c4c5ce, background #090a12; pale-tint means the main color blended about 75% toward the background.
