Prompt Seedance 2.0 tạo video cá sấu tấn công gây sốt

[Video Specifications and Overall Style]

9:16 vertical screen, 15 seconds, single continuous shot. A thrilling scene accidentally captured by a tourist with an ordinary phone inside a Chinese wildlife park. Initially calm, the photographer reacts half a beat late to a giant crocodile's ambush, causing camera shake, misalignment, and hurried re-framing of the subject. Retain the authenticity of amateur mobile footage.

[Character and Reference Locking]

The female protagonist uses preset adult Chinese female character #1 @598c0e35-7c27-4b7c-8bac-19bb206ff1c3, wearing preset outfit #2 @d57ec59a-c0a5-4eae-84f4-4f02ef21a92d, strictly maintaining the facial features, long hair, clothing style, color, and material from the references. #1 is the person, #2 is the outfit; numbers do not appear in the frame.

The administrator is a Chinese male around forty years old, short black hair, wearing khaki short-sleeved work clothes, dark trousers, with a work badge on his chest, standing behind and to the side of the female protagonist.

There are a few adult Chinese tourists in the background, wearing summer casual wear, naturally scattered along the boardwalk.

[Scene and Camera Position]

Tropical crocodile viewing area, old wooden boardwalk extending along a deep green pool, opposite bank lined with bamboo, palms, and shrubs. Thick wooden railing extends diagonally from bottom right to background.

External photographer stands about one meter behind and to the side of the female protagonist, slightly higher than her hand-held phone position, shooting vertically downwards. The right side of the frame shows the female protagonist, administrator, and boardwalk; left and bottom show the pool.

Humid daytime, natural sunlight filtering through vegetation, slight green reflection on water surface. Ordinary phone 1x main camera, slight hand shake, tilt, compression artifacts, noise in shadows, brief blur during rapid movement. No cinematic grading, drone shots, or portrait bokeh.

[Female Protagonist's Phone Orientation - Must Be Accurate]

The female protagonist is using the rear camera to film the crocodile in the water, not taking a selfie, nor showing the phone to the external photographer.

She holds the phone horizontally with both hands at the ends, fingers avoiding the rear camera. The phone is below her chest, near the outer edge of the railing, clearly tilted downwards, with the rear lens direction accurately aimed at the huge shadow underwater in the lower left.

Phone screen faces up, slightly towards her face; back and rear lens face down towards water. She looks down at the screen, observing the target in water through it.

From the external photographer's slightly higher side-rear angle, mainly see the phone screen and side edges, should not clearly see the entire phone back and camera module facing the external photographer.

Screen content matches real water surface: same water patch and blurry shadow visible, no selfie face, irrelevant scenery, or wrong direction.

When adjusting wrists slightly, rear lens always follows underwater shadow. Only when crocodile attacks does she pull back phone in fear, disrupting orientation.

[Crocodile and First Frame State]

Only one abnormally large dark gray-black crocodile. When leaping, head size approaches upper body of an adult, open mouth occupies nearly half left frame, size reference original video, no small crocodile generated.

First frame: crocodile fully submerged, only huge blurry long shadow like sunken wood. Water reflections and turbidity hide details, cannot clearly identify head, eyes, nostrils, scales, teeth, nothing exposed above water.

Crocodile maintains same volume throughout, no sudden expansion during leap.

[0-2s: Filming Underwater Shadow]

Female protagonist stands inside railing, leaning forward slightly, holding phone horizontally, aiming rear lens down at huge shadow in lower left water.

She looks down at screen facing her, shadow in screen corresponds to shadow in pool. External photographer captures phone screen, her profile, and water below from side-rear.

Administrator seriously warns:

"Ma'am, step back, don't lean on the railing!"

Water has only slight ripples, crocodile still hidden.

[2-4s: Target Approaches, Phone Follows]

Huge underwater outline slowly approaches female protagonist's position. She adjusts wrist slightly, keeping rear lens aimed at moving shadow, screen facing her, not turning phone back to photographer.

Administrator steps closer, reaching out to support her, tone urgent:

"That's not wood, it's alive! Don't lean in!"

She starts pulling body back but phone still filming water. End of segment: crocodile snout and eyes just breaking water surface.

[4-6s: Giant Crocodile Ambush]

Crocodile violently bursts water surface, huge head rises along outside of railing, open mouth instantly occupies nearly half left frame, splashing large amount of water.

Female protagonist screams, hurriedly pulls back phone and arm. Phone orientation loses stability due to shock, must have been correctly aimed before.

Crocodile briefly bites into her forearm extended outside railing and nearby fabric. Administrator immediately supports her upper arm and shoulder/back, stabilizing her center of gravity inside railing.

External photographer retreats half step in shock, camera briefly shakes upward, no cuts or wound close-ups.

[6-9s: Escape and Fall]

Crocodile briefly releases grip, head drops back, female protagonist seizes chance to retract injured forearm, administrator pulls her to inner boardwalk. Action must have clear release, arm cannot pass through closed teeth.

Phone slips from hand, flips once, falls into pool.

Crocodile slams back into water, white splash. Female protagonist covers forearm, small amount of red liquid seeps from injury, forming short thin streaks, staining fabric at contact point, one or two drops falling onto wooden boardwalk.

No deep wounds shown, no spraying, no heavy bleeding.

Administrator shouts:

"Step back! Don't reach out! Don't pick up phone!"

[9-11s: Tourist Panic]

Female protagonist retreats to middle of boardwalk, protecting injured forearm, shoulders tense, breathing rapid.

Nearby tourists first shrink back, grab companions; those further away turn upon hearing scream, some put away phones, others make way, exclaiming sequentially:

"Step back quickly!"

"Don't lean on railing!"

Crowd reaction has time lag, not synchronized, no clipping, no falling into pool. Crocodile remains underwater, no second attack.

[11-13s: Administrator Evacuation]

Administrator stands between female protagonist and railing, continuing to protect her retreat, gesturing for tourists to make way:

"Back up! Everyone don't crowd!"

A nearby tourist offers tissue, female protagonist accepts and presses same injury spot, tissue gradually stains red.

Photographer retreats slightly and corrects composition, capturing female protagonist, administrator, and panicking retreating tourists.

[13-15s: Aftermath]

Female protagonist covers forearm, gasping, trembling voice says:

"I'm scared... it really bit me!"

Administrator still protects her, warily watching pool. Background tourists whisper warnings:

"Stay away, stop filming!"

Ends with female protagonist shaken, crowd retreating, water ripples subsiding.

[Live Audio]

All live audio from phone, Chinese dialogue, no music, narration, subtitles.

Start includes low tourist chatter, bamboo leaf rustling, slight water sounds. Administrator voice near and clear, shifting from serious warning to urgent restraint as danger occurs.

During crocodile emergence: heavy water sound, female scream, nearby gasps; followed by phone splashdown, water crash, rapid panting, chaotic footsteps. Max splash and scream cause mic clipping briefly, then auto-gain recovery.

Distant tourist voices more scattered, lighter, no monster roars added.

[Continuity and Key Constraints]

Opening phone must correctly film underwater target: screen up facing protagonist, rear lens down aimed at crocodile; external photographer sees mainly screen/sides. Prohibit rear lens facing photographer while depicting filming underwater target.

First frame only blurry huge underwater shadow, no clear crocodile head/eyes/scales/teeth. Red liquid only after bite.

Maintain continuity of Character #1, Outfit #2, Administrator, Crocodile, Boardwalk. Injury always same forearm, red streaks/fabric damage/tissue press location correspond.

Only one phone, does not return to hand after fall. Protagonist/Administrator always inside railing, Crocodile @d57ec59a-c0a5-4eae-84f4-4f02ef21a92d always in pool. Maintain causal relationships of contact, weight, bite, release, retreat actions throughout.

No wound close-ups, dismemberment, deep tissue display. Single continuous shot, no slow motion, replays, studio reveals, UI overlays, watermarks.
