REFERENCE IMAGE PRIORITY: HIGHEST
CHARACTER CONSISTENCY: LOCKED
IDENTITY PRESERVATION: STRICT
FACE REPLACEMENT OR ALTERATION: NOT ALLOWED

1. ABSOLUTE IDENTITY PRESERVATION — BOTH PEOPLE

Reference Image 1 is the male character.
Reference Image 2 is the female character.

Carefully analyze both reference photographs before generating the video. Reproduce the exact same two individuals shown in those photographs. Treat each reference image as the definitive identity source for its corresponding character.

The original face of the man AND the original face of the woman must remain unchanged and recognizable throughout every frame. Preserve both identities independently. Never prioritize one person's identity over the other's.

MALE FACE LOCK:
Preserve the man's exact original face, facial geometry, face width and length, forehead, eyebrows, eyes, eye spacing, nose, cheeks, jawline, chin, lips, ears, skin tone, skin texture, facial hair, hairline, hairstyle, and every recognizable distinguishing feature. Do not generate a different male face, make him look older or younger, enlarge his face, sharpen his jaw, or turn his youthful appearance into a mature adult appearance.

FEMALE FACE LOCK:
Preserve the woman's exact original face, facial geometry, face width and length, forehead, eyebrows, eyes, eye spacing, nose, cheeks, jawline, chin, lips, ears, skin tone, skin texture, hairline, hairstyle, and every recognizable distinguishing feature. Do not generate a different female face, beautify or idealize her features, change her apparent age, reshape her face, alter her natural facial proportions, or replace her with a generic AI-generated beautiful woman.

BOTH CHARACTERS:
No face swapping, face blending, identity mixing, face regeneration, facial feature replacement, identity drift, artificial beautification, or changes to the original facial structure. Natural expressions and speech-related mouth movements are allowed, but the underlying identity must remain consistent in every shot.

2. EXACT AGE, HAIRSTYLE AND PHYSIQUE LOCK

Preserve each person's original apparent age as shown in their own reference photo. Never make either person noticeably older or younger. Do not assume that they are the same age.

Preserve each person's original haircut, hairstyle, hair length, hairline, hair color, hair texture, hair volume, and visible facial hair. Do not invent new hairstyles or add facial hair that is absent from the reference.

Preserve the original physique of BOTH people, including height, body size, shoulder width, neck length, torso, arms, limbs, body build, and overall proportions. Keep their original clothing and visible accessories.

CRITICAL MALE SIZE RULE:
Reproduce the man's original physical appearance and dimensions as faithfully as possible. Never enlarge, stretch, scale up, broaden, make taller, or make more muscular the male character to match the female. If the man appears shorter or smaller than the woman in the reference images, preserve that difference. If he appears taller or larger, preserve that instead. Never normalize their heights or body sizes.

Apply the same strict body-preservation rule to the woman. Do not reshape either person's body to create a conventional-looking couple.

Do not add unrequested makeup, jewelry, accessories, clothing, or other physical features. Natural movement must not alter either person's identity, age, or physique.

3. CINEMATIC ENVIRONMENT AND LIGHTING

Create an intimate, professionally filmed romantic drama with warm candlelight, soft golden highlights, subtle amber lights, elegant shadows, and realistic background bokeh.

Use natural skin tones, realistic skin texture, balanced contrast, and soft cinematic lighting. Keep both faces clearly visible and recognizable. Do not use lighting, color grading, blur, or shadows that conceal or change their original facial features.

Maintain the same location, wardrobe, and lighting direction throughout the video. Use natural portrait perspective, smooth transitions, subtle camera movement, realistic breathing, gentle blinking, and believable expressions.

Avoid extreme close-ups, wide-angle distortion, excessive zoom, unnecessary head turns, facial warping, and full-scene slow motion. Use natural real-time movement. Cinematic beauty must never take priority over identity accuracy.

4. EXACT 10-SECOND STORY AND DIALOGUE

Follow the timing and dialogue exactly. Do not add, remove, reorder, or rewrite any spoken words.

0.0–2.0 seconds — MAN:
Dialogue: "I love you."
Begin with a natural chest-up two-shot of the man and woman facing each other. The man looks into her eyes and speaks sincerely. Keep his original face, age, hairstyle, and physique unchanged.

2.0–3.0 seconds — WOMAN:
Dialogue: "I know."
Cut smoothly to the woman. She responds gently with a subtle, affectionate expression. Preserve her exact original face and apparent age.

3.0–4.4 seconds — MAN:
Dialogue: "That's all I get?"
Cut back to the man. He gives a small, playful smile while maintaining his original facial structure.

4.4–5.4 seconds — WOMAN:
Dialogue: "What do you want?"
The woman looks at him affectionately and replies naturally. Keep her facial proportions and hairstyle unchanged.

5.4–6.8 seconds — MAN:
Dialogue: "Say it back."
The man moves slightly closer without changing his natural posture or proportions. Use a subtle camera push-in without distorting his face.

6.8–8.0 seconds — WOMAN:
Dialogue: "I love you."
She speaks clearly and sincerely with accurate lip synchronization. Her original face must remain recognizable.

8.0–8.8 seconds — MAN:
Dialogue: "Again."
The man whispers this single word naturally. Do not add any other words.

8.8–10.0 seconds — WOMAN:
Dialogue: "I love you."
The woman MUST speak these exact words. The woman, not the man, delivers the final line. As she responds, the man gently draws her into a natural, anatomically correct embrace.

End at exactly 10.0 seconds with the couple embracing warmly. Preserve both original faces and body proportions as much as possible during the embrace. Do not replace the final dialogue with silence, a kiss, or another action.

5. BACKGROUND MUSIC AND VOICE CONTROL

Start romantic instrumental music at exactly 0.0 seconds and continue it uninterrupted until the final frame.

Use expressive piano, warm strings, gentle acoustic guitar, and a soft cinematic rhythm. Let the music build subtly toward the ending without overpowering the dialogue.

Use a natural male voice for all male lines and a distinct, gentle female voice for all female lines. Only the assigned speaker should articulate each line. The listening character must react naturally without accidentally speaking or mimicking the dialogue.

Keep all eight lines clear, correctly timed, and accurately synchronized with the appropriate speaker's lips.

No narrator, extra dialogue, humming, distracting sound effects, sudden music changes, or abrupt audio cuts.

No female face alteration.

7. FINAL PRIORITY ORDER

Priority 1: Exact original male and female facial identities.
Priority 2: Original apparent ages, hairstyles, facial hair, skin tones, and facial proportions.
Priority 3: Original physique, height, body size, limbs, clothing, and relative physical differences.
Priority 4: Exact dialogue, correct speaker assignment, lip synchronization, and natural acting.
Priority 5: Romantic music, cinematic lighting, camera composition, and atmosphere.

If any camera angle, lighting effect, facial expression, or movement risks changing either person's appearance, simplify that element. Never sacrifice the man's or woman's original identity for cinematic beauty or visual symmetry.

FINAL REQUIREMENT:
The finished video must depict the same man from Reference Image 1 and the same woman from Reference Image 2. Both must retain their original recognizable faces, apparent ages, facial features, hairstyles, facial hair where present, skin tones, body sizes, relative heights, clothing, and overall physique throughout the entire 10-second video. Their only changes should be natural expressions and movements required for the dialogue and romantic embrace.
