Telescopic Handle Range Sequence

Use [product photos], [documented collapsed and extended lengths] and [approved lock-position details]. Create a 12-second product demo extending the handle through the supplied verified motion to a confirmed lock position. Keep segment count and nesting consistent; do not show a lock at an unsupported intermediate point.

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.
