Edit @Video1, preserving the exact existing shot sequence, cut timestamps, total duration, camera framing and movement, street set, storefronts, lamppost and blue car. Recast all FIVE main dancing performers as complete people, including face, hair, skin, body proportions, clothing and accessories. Use @Image1 for the central foreground lead, originally wearing a white fedora and pink blazer. Use the FOUR distinct adults in @Image2 as the four existing supporting dancers; assign them left to right in the first wide ensemble shot, skipping the lead. Keep each assignment consistent through every close-up, cut, occlusion and reappearance. Replace original hats, jackets and trousers completely with the reference wardrobes. The supplied images define casting and wardrobe; the video defines choreography, footwork, body positions, head turns, hand gestures, lip-opening rhythm, blocking and timing. Preserve every original action and shot boundary without adding an introduction, finale, new camera movement or extra performers. Fill all source face blurs with clear natural replacement faces. Keep identities, outfits, hands, feet and anatomy temporally coherent. Do not show the studio photo backgrounds, reference boards, still-photo inserts, captions, text, logos or watermarks. Keep the original street background and lighting. No sound. Cast direction: Theme: a group of five ADULT Hogwarts wizard alumni performing Uptown Funk in the original street. Lead is the original adult man in @Image1, wearing flowing black wizard robes with burgundy lining, red-and-gold house scarf/tie, white shirt, charcoal waistcoat and trousers, black shoes. Supporting adults in @Image2 are, left to right, green/silver house robes, yellow/black house robes, blue/bronze house robes and red/gold house robes. These four are separate existing dancers, not one extra guest. Reproduce their distinct faces and whole outfits. Scarves and robes move naturally with the original dance. Hands remain free, any wand stays tucked at the belt. Keep mouths unobstructed. No magical effects or changed scenery. All five main performers must visibly wear wizard robes, including in the group wide shots.

开始创作之前
了解输入、复用与检查中的几个实际问题。
01应该准备哪些输入?
动作迁移与物体替换需要一段原视频和 1–8 张参考图;Restyle 使用一段视频、一种风格与 0–5 张可选角色图。选取 4–30 秒片段;未选取时最多使用前 30 秒。画幅跟随准备后的原片,Restyle 的帧数与节奏可能变化。物体替换要求原片每帧至少包含 409,600 像素。
02必须写提示词吗?
两种模式都接受空提示词。需要更明确的变化时,说明目标及每张有序参考图的作用。无提示词案例会加载空提示词和对应原始输入。
03“使用此提示词”会加载什么?
完整原视频、有序参考图、提示词和对应模式,兼容的当前设置会保留。加载输入不会开始生成或扣积分;检查草稿后,再单独提交。
04目标之外的画面会完全相同吗?
物体替换会引导目标周围场景保持一致,但不保证逐像素相同。请贯穿整段检查边缘、遮挡、光线、接触关系和背景。
05怎样确认费用?
准备后的源片时长向上取整到整秒,再按所选分辨率计费。提交前检查工作区积分报价,每次新生成独立报价与结算。
