🔒 PRODUCT LOCK (ABSOLUTELY CRITICAL)

Car cup holder expander must be EXACTLY identical to the reference image

Same shape, same proportions, same color

NO deformation

NO redesign

NO proportion change

NO enhancement, smoothing, or AI “beautification”

Product must stay HD, sharp, rigid, and unchanged in all shots

If any detail is unclear, leave it unchanged

⏱ Scene Breakdown — 15s Mixed Cut
0–2s | Hook

Top-down shot inside a real car.
An oversized bottle is placed into the factory cup holder — it doesn’t fit and leans sideways.

2–4s | Pain Confirmation

Quick cut, same angle.
The bottle rocks slightly as the car idles.
Driver’s hand steadies it (hands only).

4–6s | Solution Reveal

The bottle is removed.
The cup holder expander is shown clearly for half a second, then inserted straight down into the original cup holder.

6–8s | Installation Close-up

Side-angle close-up.
Expander locks into place with a subtle plastic contact sound.
No bending, no force.

8–10s | Fit Test

Same oversized bottle placed into the expander.
It drops in cleanly, centered and upright.

10–12s | Stability Test (Driving)

Side view.
Car makes a gentle turn or rolls over a small bump.
Bottle stays completely still.

12–15s | End Lock Shot

Tight close-up on the expander holding the bottle.
Clean, steady frame held for conversion pause.
