Replacement Cover Scope Motion Study

Create a 12-second reference-led video for advertisement using [cover dimensions], [compatible frame list] and [approved offer]. Core visible action: a fabric replacement cover is shown beside an outlined excluded frame. The intended task is to write replacement-cover copy that clearly excludes the frame and identifies verified fit limits without inventing universal compatibility. 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.
