Marbled Paper Vein Direction Motion Study

Create a 12-second reference-led video for art using [marbled paper references], [crop dimensions] and [binding orientation]. Core visible action: two book-cover crops align with the same diagonal vein direction while retaining their true separate edges. The intended task is to plan a crop that preserves the chosen vein direction across front and back covers; do not invent a continuous match where reference material ends. Use three shots: establish at 0–3 seconds, demonstrate at 3–9 seconds, hold the result at 9–12 seconds. Make the result understandable without sound. Use one consistent set of props; do not add unsupported labels, quantities or transformations.

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.
