Runway Gen-4 Turbo — 文生与图生视频

16:9 cinematic product hero, one continuous 10-second take, no cuts. Use the uploaded still as the only product reference — matte white skincare jar on black reflective surface. Camera: single slow arc from front-left to front-right with gentle parallax — one move only. Time beats: 0–3s wide hero; 3–7s arc eases through three-quarter angle; 7–10s settle with micro-reflections, motion nearly still at end. Keep jar silhouette, lid geometry, and blank label area identical — no new text, no logo invention. Photoreal materials, no on-screen typography, no hands.

Vertical 9:16, one continuous 5-second take. Medium close-up: woman late 20s, neutral wardrobe, soft window light from camera-left. Natural smile toward camera — no cuts, no on-screen text. Subtle handheld micro-movement; stable identity throughout.

16:9 premium cinematic hero, exactly 5 seconds. Matte black earbuds case on brushed aluminum, cool rim light from above-left. Slow push-in — no readable brand text. Photoreal, stable horizon, no typography.

Vertical 9:16, one continuous 10-second take. Use uploaded portrait as identity lock — same face, hair, olive jacket. Subject walks toward camera on clean sidewalk, golden hour light. Eye-level medium, slow dolly back; no crowd or signage.
