How do I use timestamps in prompts for precise camera and action control?
Break the scene into time ranges within your chosen duration. For example: “0–5s: Medium shot of a creator lifting a product. 5–10s: Slowly push in as the creator turns it toward the camera. 10–15s: Hold a close-up of the product.” Keep actions achievable and specify what remains unchanged. Timestamps guide pacing rather than guarantee frame-exact timing.
