如何為 Wan 2.2 撰寫提示詞

最重要的規則

1. 1

   開頭放最多四個電影感標籤

   從時段、光線、景別、角度和構圖中挑選:「Side lighting, medium shot, sunrise time, warm colors.」超過四個就會互相稀釋效果。

2. 2

   從頭到尾說明動作

   「She reaches for the cup, lifts it, and blows across the surface.」只是站著不動的主體,會讓影片幾乎沒有動態。

3. 3

   讓背景也動起來

   雲朵飄移、樹葉搖曳、車流經過。主體後方哪怕只有一點動靜,畫面也會更生動。

4. 4

   不要寫聲音和氛圍描述

   不要寫對白、音樂或音效,因為影片是無聲的。也不要寫「the scene is full of life」這類句子,直接描述畫面中呈現這種感覺的內容。

5. 5

   使用圖片時,只寫動態

   有了首幀,畫面的樣貌就已經確定。只需說明什麼在動、鏡頭怎麼運動,並控制在 100 字以內。

可以參考的提示詞

• 動態人像

  Practical lighting, warm colors, night time, medium close-up shot. A woman in her thirties with cropped black hair, a mustard knit cardigan and round tortoiseshell glasses sits at a cluttered desk under a green-shaded lamp. She leans in to read a letter, frowns, then breaks into a slow smile and presses the page to her chest. Behind her, rain streaks the dark window and the reflection of the lamp trembles in the glass.

  為什麼有效: 四個標籤決定了光線和構圖,動作有開頭、轉折和結尾,而雨讓背景有了自己的動態。

• 沒有人物的風景

  Aerial, extreme wide shot, dawn time, soft lighting. Mist rolls slowly across terraced rice fields that step down a green hillside, the flooded terraces mirroring a pale pink sky. A narrow river winds along the valley floor, and a flock of white egrets lifts off the water and glides across the frame.

  為什麼有效: 提示詞沒有要求人物,所以不會出現人物;薄霧、河流和鳥兒帶來了動態。

• 從首格畫面開始

  The girl in the yellow raincoat jumps into the puddle with both feet, water splashing up around her boots, then looks up and laughs. The camera pulls back slowly.

  為什麼有效: 將靜態圖片上傳為首幀。提示詞依照圖片中的樣子指出主體,只說明會動的部分。

• 風格化影片

  Claymation. A chubby clay chef in a tall white hat flips a pancake in a tiny frying pan; it spins high into the air, and he catches it on a plate with a proud little bow. Behind him, steam puffs from a row of clay pots on a miniature stove.

  為什麼有效: 先寫明風格名稱,並省略電影感標籤,只要不是寫實照片,都應該這樣做。
