Bottle Cap Tether Clearance Film

Create an eight-second cap demonstration from [operation reference]. Open the cap along its actual path, place it in the demonstrated resting position and hold the bottle mouth in view. Keep the tether attached throughout, with no clipping or added hinge. Do not show liquid flow unless supported by [approved demo].

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.
