Prompt này cũng dùng được trên Higgsfield, vì nền tảng đó có sẵn model Seedance.
## I. Core Shot
- Final duration: approximately 15 seconds.
- Recommended aspect ratio: 16:9. The original file uses a 9:16 tutorial layout, but the character performance footage itself is close to horizontal 16:9.
- Shot format: third-person, frontal over-the-shoulder composition, one continuous take, no shot/reverse-shot.
- Shot size change: begin in a close-up/medium close-up, naturally widening to a looser medium close-up at the end as the female lead steps back.
- Emotional progression: tense preparation → hears a familiar greeting → briefly falters → masks it with a bitter smile → declares the relationship over → leaves with restraint.
- Core performance chain: stimulus (door opens, hears a male voice) → pause of understanding → involuntary reaction (closes eyes, inhales) → deliberate choice (looks up, bitter smile) → dialogue (“WE'RE DONE.”) → lingering emotion (still reluctant to let go, but creates distance).
## II. Characters and Setting
### Female lead
Reference uploaded image {{Mixed 1}}. Soft, clean appearance, realistic skin texture, no excessive skin smoothing. She had already made her decision before coming here, but seeing the male lead still makes her waver; her performance is not angry, but a farewell after suppressing pain.
### Male lead
Appears only as a dark, out-of-focus shoulder and head silhouette in the front right of the frame. His face is not shown; he does not draw focus or enter a sharp depth of field. His voice is warm and affectionate, and he has not yet realized that she came to end the relationship.
### Setting and atmosphere
An entrance by a residential doorway or near a courtyard, with softened green plants, a light gray path, and a few warm-colored circular bokeh lights visible in the background. The overall light feels like late afternoon: a soft cool-white key light from approximately 45° in front of the characters on the left, with a small amount of warm golden rim light in the background. The space is quiet, and the air seems recently rained on or humid. The atmosphere is gentle, restrained, and distant; avoid strongly dramatic lighting.
> Note: The focal length and lighting parameters are reshooting recommendations inferred from the image, not metadata from the original video. Use a full-frame equivalent 70–100mm medium telephoto lens and shallow depth of field; keep focus locked on the female lead’s eyes.
## III. Continuous 15-Second Performance Script
### 0.0–0.8 seconds | The door opens, revealing the characters
At first, the male lead’s dark, heavily defocused body silhouette obscures most of the frame. As the door opens, he shifts slightly toward the right side of the camera, revealing the female lead standing outside, facing him. Keep the camera stable; no sudden push-ins or pull-outs.
The female lead does not immediately look up. She slightly lowers her chin, her gaze resting near the male lead’s chest or the threshold, and her lips are naturally parted a little. Her body seems still, but her shoulders and neck carry slight tension, as if she had rehearsed this many times outside the door.
Sound: a faint door opening, fabric rustling, quiet outdoor ambience.
### 0.8–3.2 seconds | Use breathing to hold back emotion
The female lead slowly inhales, with very subtle movement: her chest and collarbone area rise slightly, her shoulders tense a little, then slowly settle. Her gaze stays lowered as her eyelids gradually close; keep her eyes closed slightly longer than a normal blink.
Do not make her cry immediately or furrow her brows dramatically. Preserve only two visible signals: deeper breathing and slight tightening at the corners of her lips. She is trying to push back the emotion that is about to overwhelm her.
Camera: fixed close-up, shallow depth of field, with the male lead’s blurred silhouette remaining on the right side of the frame as a source of relational pressure.
### 3.2–5.4 seconds | She hears a familiar greeting
The male lead says off-screen naturally: “Hey, what's up, baby?” His tone is casual, with a hint of a smile, as if greeting her as usual.
The female lead keeps her eyes closed for about half a second, letting the voice truly register in her body. Then she swallows lightly; only a faint tension appears between her brows. She does not look up or reply. She slowly exhales the breath she just took, her lips moving slightly without forming words.
Performance focus: her reaction must happen after she hears the line; the familiar affection briefly shakes her, but does not change her decision.
### 5.4–7.5 seconds | She looks up, meets his gaze, briefly falters
The female lead opens her eyes first, then raises her gaze, and only then slightly lifts her chin; complete these as three separate movements. Her focus shifts slowly from the male lead’s chest to his eyes. Her gaze changes from unfocused to clear; her eyes look moist, but no tears fall.
She holds eye contact with the male lead. Her breathing becomes slightly uneven, and her lips gently press together, while her face remains restrained. Do not push the camera in; let the audience notice the change themselves.
### 7.5–9.3 seconds | A bitter smile becomes her last line of defense
The female lead raises one corner of her mouth just slightly, forming an incomplete, slightly asymmetrical bitter smile. The smile stays only at the corners of her mouth and does not reach her eyes. She continues looking at the male lead, as if confirming that the person she knows is still there, while also confirming that the relationship cannot continue.
The bitter smile lasts less than two seconds, then slowly fades. Do not immediately turn her expression cold; retain a little reluctance and hurt, letting sadness and determination coexist.
### 9.3–10.6 seconds | She declares it over
The female lead maintains eye contact and says in a very soft, clear voice, without anger: “We're done.” Leave a brief inhale before she speaks; “We're” still carries a trace of tenderness, while her gaze becomes steadier as “done” lands. Her mouth moves naturally; do not over-enunciate or shake her head broadly. After the line, she gently closes her lips and pauses for half a second.
Sound: preserve natural breathing and faint ambient sound; no sentimental music and no additional subtitles.
### 10.6–13.4 seconds | Let silence complete the separation
The female lead continues looking at the male lead and does not leave immediately. Her expression gradually returns to near-calm; her eyes still glisten, and her chin tightens slightly. Her weight begins shifting from her front foot to her back foot, showing that she is preparing to leave, while her upper body still hesitates to create distance.
Keep the camera still; do not cut to the male lead’s reaction. He remains only as an out-of-focus foreground figure on the right, so the audience can feel the weight of her words only through her face.
### 13.4–15.1 seconds | She steps back, making the distance between them tangible
The female lead slowly takes one or two steps backward, initially keeping her eyes on the male lead’s face. Her body naturally becomes smaller in the frame, and the shot widens from a close-up to a medium close-up; her shoulders relax, her posture straightens, and her expression shifts from pain to distant resolve.
Final state: the distance between the female lead and the male lead has grown. She does not turn and run away or break down emotionally; she completes the farewell with a calm step backward. Keep focus on her face, with the background and the male lead softly blurred.
## IV. Cinematography Execution Notes
- Place the camera over the male lead’s shoulder, close to the female lead’s eye level. The male lead is in the right foreground; the female lead is centered, slightly left.
- Maintain the same eyeline axis throughout; do not cross the axis or suddenly switch to a point-of-view angle.
- Use a fixed camera or only a very slight, steady breathing-like movement; the change in shot size at the end comes from the female lead stepping back, not from a noticeable zoom.
- Keep focus on the female lead’s eyes; the male lead’s silhouette, courtyard background, and light bokeh stay out of focus.
- Protect the female lead’s skin tones and pale golden strands of hair from blown highlights; retain realistic skin texture, small asymmetries, and natural blinking.
- Keep each emotional beat to only 1–3 visible signals; avoid mechanical movement of the eyebrows, eyes, nostrils, and corners of the mouth all at once.
## V. Continuity and Prohibitions
- Keep the female lead’s identity, hairstyle, earrings, necklace, gray collared knit top, body type, and perceived age consistent throughout.
- The male lead never shows his face, never draws focus, does not suddenly become sharply focused, and has no physical contact with the female lead.
- Do not add rolling tears, hysterical crying, angry staring, sudden laughter, or exaggerated head shaking.
- Do not use shot/reverse-shot, a rapid push-in, an orbiting camera, a sudden zoom, or multiple camera angles.
- Do not change the direction of light, background space, the axis of their positions, or the height of the female lead’s eyeline.
- Do not carry over the reference image at the top of the original tutorial video, scrolling text at the bottom, platform watermark, or layout black bars; reproduce only the camera and emotional logic of the character performance footage.
