seedance 提示詞：光學變焦運鏡教學（江南雨後古巷 · 兩人重逢 · 固定機位只靠變焦講故事）

時長與鏡頭：約 13 秒三段，全程同一個機位：廣—中景推進 → 長焦壓縮 + 移焦 → 極慢推進到中近景。這是一條"運鏡教學"型提示詞：大多數 AI 影片動不動就環繞、橫移，而這裏刻意只用光學變焦，讓"兩人距離越來越近"的情緒完全由鏡頭焦段來表達。

要點：①反覆強調"機位不動、只做光學變焦"，並在禁止項裏點名橫移、環繞、無人機；②用"前景行人遮擋""廊柱前景框"製造層次；③長焦壓縮空間是真實鏡頭特性，寫出"縱深變淺、兩人視覺距離拉近"，模型更容易理解你要的效果。

怎麼填變量：[江南古鎮] 可以換成"民國老街""日式小站月台""雪後的衚衕"；台詞 [好久不見。] 換成任意一句短台詞。兩個人物也可以是一男一女、或者一人一寵物。

常見失敗與調整：

• 模型還是做了推軌或環繞：把"禁止橫移、環繞"挪到提示詞最前面，並縮短總時長。
• 兩人左右位置互換：寫"女主 A 始終在畫面左側，女主 B 始終在右側"。
• 出現現代電線杆、空調外機：負面提示詞點名這些物體。

[Global Settings]
Ancient-style realistic cinematic shot, Eastern classical life narrative, Jiangnan ancient town after rain: bluestone steps, blue bricks and black tiles, wooden corridors, carved wooden doors, bamboo curtains, wet stone alleys. Soft diffused light under cloudy skies, low contrast, fusion of cold gray-green and warm wood tones, slight 35mm film grain, realistic skin, wood, stone, and fabric textures, cinematic shallow depth of field, 8K, 16:9.

Female Lead A: Image 1
Female Lead B: Image 2

Strictly maintain character identity, spatial position, left-right relationship, direction of movement, weather, lighting, and color tone continuity throughout the video.

[Core Cinematography Technique]
The entire video uses "progressive optical zoom" as the sole core camera movement. The camera remains as fixed as possible, relying not on physical movement but on slow, continuous optical push-ins and pull-outs to change the characters' screen proportion and spatial relationships. Maintain real lens compression, depth of field changes, and optical characteristics; prohibit digital cropping. Foreground occlusion, shallow depth of field, and focus shifts assist the narrative, forming "discovery from afar -> eye contact across the alley -> spatial compression -> emotional confirmation."

[0-4s]
Medium shot start, 35mm, fixed camera, eye level. Female Lead A slowly descends along the bluestone steps to the alley entrance, stops, turns, and looks up, seeing Female Lead B under the distant corridor eaves. The shot begins with a wider environmental relationship composition, only slowly optically pushing in, gradually tightening to a medium shot of Female Lead A, with no camera movement.

Town pedestrians pass horizontally through the foreground from left and right, creating natural blurred occlusions at close range, while Female Lead A remains clear; exposure, color temperature, and light/shadow remain stable during occlusion. The zoom continues smoothly and restrainedly, finally forming an eye contact between Female Lead A and Female Lead B across the alley.

[4-9s]
Continuing from the previous segment, the camera position remains completely unchanged. Female Lead B slowly enters from the right foreground, approaching the wooden corridor pillar, forming a natural foreground frame with the pillar; Female Lead A is deep in the left-middle alley.

Slow continuous optical zoom, Female Lead A initially remains clear, then the shot gradually tightens, Female Lead B's foreground proportion increases, and Female Lead A recedes into the background with soft blur.
