Use the reference video as the primary motion reference. Preserve the original synchronized choreography, group formations, body movements, timing, rhythm, pacing, cut points, camera movement and framing as faithfully as possible. Do not invent new choreography, walking or posing.

REFERENCE ROLES:
The uploaded image of [HERO_IMAGE_DESCRIPTION] defines the central character's identity.
The uploaded image of [CROWD_IMAGE_DESCRIPTION] defines the surrounding characters' visual design, not the central character.

CENTRAL CHARACTER:
Replace the central performer with [HERO_DESCRIPTION] from the hero reference image. Preserve this character's recognizable identity, face, body proportions and appearance throughout. Clothing: [HERO_CLOTHING]. The central character stands completely still in the middle of the formation, arms relaxed at their sides, facing the camera, while the surrounding group moves. The central character appears exactly once. Never duplicate the central character or transfer their face to the crowd.

LOCATION:
Rebuild the scene in [LOCATION]. Preserve the original tiered formation, relative spacing, depth and the central character's position. Keep each row readable and preserve the original framing; do not zoom out solely to show every body from head to toe.

SURROUNDING GROUP:
Replace EVERY other person surrounding the central character with [CROWD_DESCRIPTION], based on the crowd reference image. Replace all rows: front, sides, middle and every background row. Leave none of the original surrounding performers unchanged. Visual details: [CROWD_APPEARANCE]. Variation rule: [IDENTICAL_OR_VARIED]. All surrounding characters hold the original formation and perform the original synchronized movements together, preserving timing, spacing and rhythm. Do not add gestures or movements based on their new appearance.

VISUAL STYLE:
[STYLE_LIGHTING_AND_PALETTE]. Keep the central character visually distinct through [HERO_CROWD_CONTRAST]. Apply the same rendering style consistently to the character, crowd and setting.

PRIORITIES:
Preserve the original camera movement and framing. Prioritize the original synchronized crowd choreography above other changes, with the explicit exception that the central character remains still. No identity drift, unintended face morphing, duplicated central character, distorted bodies, extra limbs, floating feet or random movements. No text, lettering, logos or writing anywhere in the frame.
