Create a **6-second vertical roller-coaster video** using the **uploaded picture as the identity reference for the main person in the front seat**.
Preserve the uploaded person’s **facial identity, gender traits, hairstyle, skin tone, face shape, eyes, nose, lips, and overall recognizable appearance**. Keep the person realistic throughout the entire clip.
Place the uploaded person in the **front seat of a fast-moving amusement-park roller coaster**, secured with a visible safety restraint. Recreate the same energetic selfie-style camera angle, speed, facial reactions, background motion, and roller-coaster movement as the reference video.
### 0.0–1.0s
Start with the roller coaster already moving quickly.
The camera faces backward toward the riders from directly in front of the first row, using a **wide-angle action-camera perspective**.
The uploaded person sits in the center front seat, gripping the metal safety bar with both hands.
They immediately show an excited open-mouth expression as the ride begins to dip.
Behind them, other riders are visible reacting excitedly. The amusement park appears far below, with colorful tents, rides, walkways, and small groups of people.
The background rapidly moves downward in frame, creating the sensation of descending from a high point.
### 1.0–2.0s
The roller coaster accelerates further downward.
The main person screams or laughs silently with a huge excited expression while keeping both hands on the safety bar.
Their hair and loose clothing react naturally to the strong wind.
The amusement park below becomes larger and moves rapidly behind them.
Add realistic vibration and mild camera shake from the roller-coaster track, but keep the person’s face clearly visible.
### 2.0–3.0s
The coaster reaches the lower section of the descent and begins transitioning into a turn.
The camera angle tilts slightly with the train.
The uploaded person’s body leans naturally with the force of the turn while remaining firmly restrained.
Keep their expression highly excited and energetic.
The park background begins sweeping sideways instead of only downward, with strong motion blur at the edges.
### 3.0–4.0s
The coaster enters a stronger banked turn.
The camera rolls more noticeably to one side with the car, so the sky begins occupying more of the background.
The main person remains centered, still gripping the bar while laughing or screaming with excitement.
Other riders behind lean in the same direction.
A bright blue sky and scattered clouds now dominate the upper background while parts of the coaster structure and park blur past around the edges.
### 4.0–5.0s
Continue through the turn at high speed.
The train banks further, creating a dramatic tilted composition.
The uploaded person’s hair is pushed backward by the wind, and their shoulders bounce subtly from the track vibration.
Keep the facial identity stable even during intense movement.
The background alternates rapidly between blue sky, amusement-park structures, and flashes of colorful rides.
### 5.0–6.0s
Finish with the coaster still racing forward.
The camera begins to level slightly while maintaining the fast wide-angle POV.
The uploaded person remains in the center foreground, gripping the safety bar and holding a joyful, adrenaline-filled expression.
The sky stays prominent behind the riders while the track environment streaks past at the frame edges.
End naturally while the coaster is still moving. Do not slow down or stop.
### Camera and motion requirements
Use **one continuous 6-second shot with no cuts**.
Match the reference video with:
* vertical 9:16 framing
* wide-angle action-camera lens
* camera mounted directly in front of the first-row rider
* main person centered throughout
* visible safety bar
* several riders behind the main person
* high-speed roller-coaster descent followed by a banked turn
* strong realistic wind
* natural hair and clothing movement
* subtle track vibration
* increasing camera tilt during turns
* realistic amusement-park background
* strong depth and edge motion blur
* bright daytime lighting
The roller coaster motion must feel physically realistic. The rider’s torso, head, hair, and clothing should react naturally to acceleration, gravity, wind, and turning forces.
Preserve the uploaded person’s identity throughout. Do not morph their face into the reference rider.
No dialogue, no text, no slow motion, no scene cuts, no floating body parts, no changing outfit, no distorted restraint bar, and no identity drift.
