Split Screen Speaker Attribution Film

Create a 12-second split-screen caption demo from [approved two-speaker script]. Anchor captions to the correct panel, include one clearly marked offscreen line and leave overlapping speech legible. Preserve panel placement and names across cuts; no invented statements or identity swaps.

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.
