Inverted Box Pleat Geometry Motion Study

Create a 10-second slow garment movement study from [pleat reference and movement clip]. Keep the inward fold geometry fixed at the top while the permitted lower section opens slightly and settles. Preserve hem length and fabric volume. Do not reverse the fold direction or invent deeper underfolds than the reference supports.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
