Departure Board Reveal

Prompt

Split-flap departure board, 9:16, one continuous locked-off shot, static camera, no zoom, no pan, no shake, no cuts. The start frame shows all five flaps blank white; the end frame shows the five flaps printed. Between them the flaps turn one at a time from top to bottom, about three seconds apart, with a still pause after each: the top flap makes a single quick mechanical half-turn around its horizontal split line and settles showing its printed panel exactly as in the end frame; then the second flap; then the third, fourth and fifth. Flaps that have not yet turned stay blank white and perfectly still. Flaps that have turned stay exactly as revealed and never change again: the letters and marks on them stay sharp, unwarped and identical to the end frame. The charcoal housing, hinge pins, gaps, lighting and background never move. Avoid: all flaps turning together, double flips, flicker, blurred or changing letters, extra panels, any change to the housing or background. No audio.
