提示詞

# 主提示詞 - 偶像全身律動（教室版）
鏡頭：
  類型：r2v
  畫面比例："9:16"
  攝影機：固定，單一連續鏡頭，不剪接
  取景：角色佔據畫面下方三分之二，腰部以上的中景，手臂完全伸展時仍須保持在畫面內
角色：
  參考：使用附加的參考圖片作為角色完整外觀依據（臉部、服裝、色彩、比例）
  美術風格：保留參考圖中原有的角色美術風格／賽璐璐陰影，不要與背景風格融合
動作：
  編舞風格：J-pop 偶像全身律動——結合指向舞手部動作的強烈臀部／胸部律動、大幅度揮臂，以及移動步法；充滿活力且動感十足，不要拘謹
  落地規則：只有節拍_7會短暫跳躍；其他所有節拍都要讓至少一隻腳始終踩在地面上，透過腿部和臀部充分發力來轉移重心，而不是僵硬不動
  動作序列：
    - 節拍_1_2：向右大步跨出並完全轉移重心，雙臂向外上方甩出，形成斜向的「V」字形，配合重拍將胸部向前挺出，臀部順著手臂方向帶動
    - 節拍_3：雙臂迅速甩下並橫掃過身體，軀幹隨動作扭轉，最後右手俐落地指向鏡頭
    - 節拍_4：快速回到中心，胸部小幅度挺出，並在弱拍時向右頂臀
    - 節拍_5_6：以節拍_1_2的鏡像動作向左進行——大步跨出，雙臂朝另一側斜向甩出，臀部隨之帶動，胸部挺出
    - 節拍_7：充滿活力的重拍——原地乾淨俐落、受控地跳一次（雙腳短暫同時離地，並同時落地），落地時雙臂向下猛力揮動以加強力度；這是整段動作中唯一的高能量高潮
    - 節拍_8：落地後雙腳踩穩，身體下沉進入扎實的律動——屈膝，軀幹由胸部到臀部做小幅度的身體波浪
    - 節拍_9_10：雙重指向組合——右手向前指並向前踏步，緊接著左手向前指，同時重心往後收回，臀部持續左右擺動
    - 節拍_11_12：全身旋轉展開——以軸心步快速轉身 180 度（雙腳保持踩地，一腳作為軸心旋轉），轉身時雙臂向外掃開，最後重新面向鏡頭，雙臂張開做出寬幅的「sparkle」手勢
    - 循環：從節拍_1開始無縫重複整段動作
  速度：節奏明快、推進感強、充滿高能量的偶像流行樂速度；動作幅度大且自信，轉換要俐落，不能拖沓
  動作備註：不要慢動作，不要變速，全程保持自然且固定的播放速度；節拍_7的跳躍必須呈現一次乾淨俐落、受控的起跳與落地，不要反覆彈跳；其他所有節拍都要保持踩地，動作主要透過臀部／軀幹／手臂的幅度帶動，而不是向上跳起
場景：
  地點：放學後的教室，沒有其他學生
  時段：傍晚／入夜前，溫暖的光線透過窗戶照入
  環境細節：背景中以柔和的剪影呈現一排排課桌椅、黑板

# Main Prompt - Idol Full-Body Groove (Classroom Ver.)
shot:
  type: r2v
  aspect_ratio: "9:16"
  camera: fixed, single continuous shot, no cuts
  framing: character occupies lower two-thirds of frame, medium shot from waist up, full arm extension should remain within frame
character:
  reference: use attached reference image for full appearance (face, outfit, colors, proportions)
  art_style: preserve original character art style / cel-shading from reference, do not blend with background style
motion:
  choreography_style: J-pop idol full-body groove - point dance hand accents combined with strong hip/chest movement, wide arm throws, and traveling footwork; energetic and dynamic, not restrained
  ground_rule: only beat_7 involves a brief hop; all other beats keep at least one foot grounded at all times, weight shifts through full leg and hip engagement rather than staying stiff
  sequence:
    - beat_1_2: wide step to the right with full weight transfer, both arms throw outward and up into a diagonal "V" shape, chest pops forward on the accent, hips follow the arm direction
    - beat_3: arms whip back down and across the body, torso twists with the motion, right hand ends in a sharp point toward the camera
    - beat_4: quick recover to center, small chest pop plus hip bump to the right on the offbeat
    - beat_5_6: mirror of beat_1_2 to the left - wide step, arms throw diagonally the other way, hips follow, chest pop
    - beat_7: energetic accent beat - one clean, controlled hop in place (both feet leave the floor briefly together, land together), arms pump downward on the landing for emphasis; this is the single high-energy peak of the sequence
    - beat_8: land, feet planted, body drops into a grounded groove - knees bent, torso rolls in a small body wave from chest to hips
    - beat_9_10: double point combo - right hand points forward with a step forward, immediately followed by left hand pointing forward with weight recovering back, hips keep swaying underneath
    - beat_11_12: full-body spin-out - a quick 180-degree turn using a pivot step (feet stay grounded, one foot pivots), arms sweep out during the turn, ending facing camera again with both arms opening into a wide "sparkle" gesture
    - loop: sequence repeats seamlessly from beat_1
  tempo: upbeat, driving, high-energy idol-pop tempo; gestures are large and confident, transitions snap rather than drift
  motion_notes: no slow motion, no speed ramping, natural constant playback speed throughout; beat_7's hop must read as one clean controlled jump-and-land, not repeated bouncing; all other beats stay grounded with movement driven by hip/torso/arm amplitude rather than vertical lift
setting:
  location: after-school classroom, empty of other students
  time_of_day: late afternoon / early evening, warm light through windows
  environment_details: rows of desks and chairs as soft silhouettes in the background, chalkboard
