Use the uploaded reference VIDEO as the exact motion, choreography, camera, framing, timing, pacing, shot duration and cut-point reference.
Use @image1 / the uploaded photo as the STRICT identity reference for the MAIN MAN.
The final video should feel like the SAME original video, but with the original central white-shirted man completely replaced by the man from @image1 .
Do NOT recreate or preserve the original man's face or identity.
IDENTITY — @image1 :
The central character is the exact same man shown in @image1 .
Preserve his: - exact face - facial structure - jawline - cheekbones - nose - eyes - eyebrows - lips - ears - skin tone - natural facial proportions - black hairstyle - hair volume and texture - beard and moustache - eyeglasses
Maximum identity preservation throughout the entire video.
He must remain recognizably the same person from the uploaded photograph in every shot and every angle.
NO face morphing. NO identity drift. NO changing facial structure. NO different hairstyle. NO removing his beard. NO changing his glasses. NO beautification or artificial facial retouching.
CHARACTER REPLACEMENT:
Replace ONLY the original central man with @image1 .
Keep his exact position, scale, body movement, gestures, walking path, head movements, smoking actions and timing from the reference video.
Everything the original central man does in the reference video should be performed by the @image1 character at the same moment and with the same choreography.
WARDROBE:
Dress @image1 in the character-reference outfit:
Acid lime green #d4ff3f single-breasted blazer, notch lapels, two buttons, buttoned closed, slightly oversized shoulders.
Plain white cotton shirt underneath.
Narrow black knitted tie, neatly knotted.
Straight black trousers.
Plain black leather ankle boots, low heel.
No jewellery. No watch. No belt. No bag. No phone. No logos or patterns.
The lime blazer must remain exactly #d4ff3f throughout the video.
IMPORTANT: Do not let the wardrobe replacement change the original choreography or composition.
SMOKING ACTION:
Preserve the smoking sequence from the reference video exactly.
At the beginning, the central character holds a cigarette naturally between his fingers and brings it to his mouth.
He lights the cigarette using the same hand movements, timing and body positioning as the reference video.
He takes a drag and naturally exhales smoke.
Preserve the original: - hand position - cigarette position - lighter movement - timing - head movement - facial expression - smoke timing - arm movement
The smoking action should look physically natural and cinematic.
Do not exaggerate the smoke. Do not create excessive smoke. No smoking action should occur from any other character.
All other characters remain unchanged.
EXACT ORIGINAL ACTION / TIMING:
0–4 SECONDS: Match the reference video exactly.
The central character is shown smoking. He brings the cigarette toward his mouth, lights it, takes a drag and exhales.
Match the original close framing, facial positioning, hand movements and timing.
4–11 SECONDS: Match the reference video exactly.
The character turns away from camera and moves forward into the crowd using the exact same movement and timing as the original man.
Preserve his body position, walking speed, direction and camera framing.
11–17 SECONDS: Match the original choreography exactly.
The character moves back toward the central position and performs the same gestures and movements as the original man.
Do not invent new actions.
17–22 SECONDS: The character reaches and holds the same central position as the reference.
He becomes calm and composed.
Maintain the exact same camera composition.
22–30 SECONDS: The crowd begins the same synchronized chaotic movement from the reference.
The central character remains calm and controlled in the center while the surrounding crowd moves violently and rhythmically around him.
Match the exact timing, intensity and choreography of the original crowd movement.
The central character must remain clearly identifiable and visually separated from the crowd.
CAMERA:
COPY THE REFERENCE VIDEO'S CAMERA LANGUAGE EXACTLY.
Preserve: - camera position - camera height - camera distance - lens perspective - focal length feel - framing - depth of field - camera movement - push/pull movement - tracking - camera shake if present - zoom - subject scale - transitions - shot duration - exact cut points
Do NOT create new shots.
Do NOT add new camera movements.
Do NOT change the original video's pacing.
The output should have the same visual rhythm and edit structure as the reference video.
CROWD:
Keep the original crowd concept and choreography from the reference video.
Large group of young men surrounding the central character.
Preserve their: - positions - density - formation - movements - synchronized choreography - timing - background behavior
Do not replace the crowd with women.
Do not introduce new characters.
Do not allow anyone else to become visually dominant over the main character.
Only the central character is replaced.
LOCATION:
Preserve the same environment and architecture as the reference video.
Keep the same: - concrete/architectural setting - stairs - background structure - crowd arrangement - environmental depth - overall composition
Do not redesign the location.
Do not introduce new buildings or props.
LIGHTING / COLOR:
Preserve the reference video's overall cinematic lighting and color grading.
Keep the dark, moody atmosphere.
The acid lime blazer #d4ff3f should be the distinctive color of the central character.
Keep natural skin tones.
Realistic shadows and highlights.
No artificial glow. No haze. No bloom. No excessive smoke. No fantasy lighting.
VISUAL STYLE:
Photorealistic cinematic live-action footage.
Natural human motion. Natural body physics. Realistic fabric. Realistic hair. Realistic skin. Realistic cigarette smoke. Realistic lighting.
No CGI appearance. No animation. No cartoon. No plastic skin. No face distortion. No duplicated main character.
CRITICAL INSTRUCTION:
REFERENCE VIDEO = controls EVERYTHING about the original video's motion.
@image1 = controls ONLY the identity and appearance of the replacement central character.
Replace the original central man with @image1 while preserving the original video's actions, choreography, camera, timing, pacing, framing and cuts as closely as possible.
The result should look like the original video was filmed with @image1 instead of the original actor.
ONE MAIN CHARACTER ONLY. NO IDENTITY DRIFT. NO EXTRA VERSION OF @image1 . For Seedance 2.5, the key line is: “Reference video controls motion; @image1 controls the replacement actor's identity.”
