Seedance 2.5 提示詞
陽光下的老庭院裡，一名女子站在前景，抬頭往後看；庭院建築的後方，一隻巨大無比的拼布小怪獸緩緩探出頭來，友善地俯看著她。 溫暖的日光，庭院的建築與女子維持正常的比例。 強制透視：固定機位，利用前後的距離與畫面的對齊，讓遠在建築後方的小怪獸看起來比整座庭院還要巨大，與前景的女子形成懸殊的比例。 聲音包含低沉的腳步震動與微風。

效果對照
基準圖中，小型 Ruk 與成人比例的 MeiHua 同站在庭院內。效果圖讓巨大的 Ruk 從後方建築上方探出，院牆遮住牠的下半身，MeiHua 與門窗保持原有比例，兩者友善對望。相同建築突然成為尺度參照，觀眾像重新發現一座小人國；本例以生成影像呈現透視與尺度錯覺的視覺結果。

Edit the actual selected baseline A, titled 陽光庭院中的溫柔邂逅, into exactly one finished 16:9 landscape image. This is a friendly miniature-world scale revelation. Keep the woman's world unchanged; reveal one truly gigantic original Ruk BEHIND the courtyard architecture. ACTUAL INPUT AND FIXED WORLD Use this selected A as the actual edit input. Its original courtyard and MeiHua establish the fixed world scale, composition and observer viewpoint. The original empty courtyard 陽光下的靜謐老庭院 and the actual original Ruk.png and MeiHua.png sheets are already present in this conversation as references. Ignore the previous giant-Ruk output's changed courtyard projection. Keep the selected A's camera, lens, observer height, direction, horizon, crop and frame absolutely fixed. Retain all visible buildings, walls, doorframes, left steps, bench, distant rooftops, stone paving, vegetation and lighting in their original screen positions, proportions and perspective. Visible background edges must align with A. Do not resize the buildings or the woman, reproject the background, bend lines, stretch the door, change the courtyard structure or create a different viewpoint. REMOVE THE SMALL COURTYARD RUK Remove the original small Ruk standing on the courtyard floor in the left half of A. Restore only the floor and wall pixels it had covered, using the existing adjacent stone paving and the original empty courtyard as the reference. There must be exactly ONE Ruk in the finished image. The courtyard remains an ordinary human-scale place for MeiHua. REVEAL THE GIANT BEHIND THE ARCHITECTURE Place the one enormous Ruk OUTSIDE AND BEHIND the rear courtyard wall and surrounding buildings, never standing inside the courtyard or in front of its architecture. Reveal its huge original rounded head, pointed ears and, where space permits, upper shoulders rising from behind the rear wall and roofs into the existing central sky opening. Its head alone is enormous relative to the unchanged doors, roofs and adult woman, making the viewer suddenly realize how small this world is beside it. Use the available sky space without moving or stretching any building. It is fine to show only the giant head and a little upper body; do not force a whole body into the courtyard. The existing rear wall, roofs and buildings must visibly OCCLUDE Ruk's lower body and shoulders where they overlap. Preserve these architectural silhouettes in front of Ruk exactly where they are in A. This clear depth order is essential: MeiHua and courtyard in front, unchanged architecture in the middle, huge Ruk behind. Do not show giant feet in the courtyard, a giant hand, a floating detached head, additional limbs, destruction or a creature crushing buildings. Keep the original Ruk's connected anatomy implied naturally behind the occluding walls. Preserve its actual original non-human red, off-white and blue cracked patchwork identity, broad gentle muzzle, round yellow eyes with dark pupils, original pointed ears and illustrated material design. It is a curious, kind visitor with relaxed brows, no angry grimace or threatening pose. EXACT MUTUAL GAZE Keep MeiHua's original world scale, full-body footprint, elegant adult proportions, identity, hair, pink floral ornaments, embroidered ivory robe, black-and-gold collar and waist, shoes and one black floral fan from A. Adjust only her head and eyes as needed: she gently lifts her chin and looks up and to the LEFT toward the giant's eyes behind the wall, calm and unafraid. Position Ruk's head above and to her left, gently tilting its face DOWN toward her. Direct BOTH dark pupils down and right toward MeiHua's actual eyes, with both eye directions converging on her face. Ruk must visibly look at her, not at the viewer or into empty space. Their two gaze directions must meet. Keep their exchange gentle and friendly. Keep the original sunny colors, clear illustrated rendering and exposure. No horror, disaster, attack, giant shadow over the town, toy-like woman, text, labels, comparison panels or new decorative effects. Produce this single corrected image now.
強制透視在影片裡的作用
要揭露角色與巨物的比例差，或讓兩個相隔很遠的對象看似互動時，可以用強制透視延後觀眾對距離的判斷。切到另一角度之前，要對齊攝影機位置、遮擋邊界與背景尺度參照，讓大小錯覺仍然成立。
