如何為 Kiwi 撰寫提示詞

最重要的規則

1. 1

   寫明光線、景別與運鏡

   先交代拍攝方式:「中景,平視,柔和的晨光,暖色調。」最後再加一個運鏡。

2. 2

   描述動作:幅度多大、速度多快

   「笨拙地把雪球往前滾」比「在雪地玩耍」好。寫出什麼在動、依什麼順序,以及它對場景造成什麼影響。

3. 3

   一支片段一個場景

   Kiwi 只生成單一鏡頭,所以在同一支片段中換場景會讓畫面失敗。每個場景各做一支片段,再用剪輯軟體接起來。

4. 4

   把說的話放進引號

   引號內的台詞會逐字念出,並使用你描述的聲音:老漁夫用緩慢沙啞的嗓音說:「潮水要轉向了。」沒有引號的話,Kiwi 可能會自己編台詞。

5. 5

   有起始圖片時,只寫動態

   圖片已包含主體、場景和風格。只說明什麼在動、攝影機如何表現,不要描述外觀。

可以參考的提示詞

• 帶聲音的俏皮瞬間

  Medium shot, eye level, soft morning daylight, warm colors, center composition. A fluffy ginger kitten in a snowy back yard rolls a snowball with its front paws and pushes it forward clumsily. The snowball breaks apart; the kitten jumps back in surprise, sneezes, then creeps closer and nudges the pieces with its head, tumbling over. The camera tracks slowly at kitten height. The crunch of paws on snow, the swish of the rolling snowball, the crack as it breaks, a tiny sneeze, and a light, warm piano melody.

  為什麼有效: 先交代畫面質感,動作是有開頭和結尾的清楚連續過程,而且每個聲音都有來源。將長度設為 10 秒。

• 只有一句台詞的角色

  Low angle, medium close-up, warm tones, mixed light from a green desk lamp and grey window light. In a cluttered detective's office, a fox in a brown trench coat and grey fedora sits in a leather chair turning yellowed pages. Rain streaks the window behind him. He raises his head, ears twitching, looks straight at the camera and says in a smooth, cynical voice: "The case was cold. Colder than a fish in winter." Steady rain on glass, pages rustling. No background music.

  為什麼有效: 兩個光源營造氣氛,台詞簡短、加上引號並說明聲音,而「沒有背景音樂。」讓雨聲和翻頁聲清晰可聞。

• 讓起始圖片動起來

  The camera pulls back slowly as the two men climb the stairs; the man on the left steadies the man on the right with his hand, and both pause on the landing to catch their breath. Footsteps on stone, heavy breathing.

  為什麼有效: 把圖片加入作為起始圖片。提示詞照圖片呈現的樣子稱呼那幾位男士,並把每個字都用在動作、運鏡和聲音上。

• 貼近水面的跟拍鏡頭

  Low angle at water level, overcast daylight, muted greens. A folded paper boat drifts down a rain-filled gutter, spinning slowly as it bumps past leaves and pebbles, rain dimpling the water around it. The camera tracks alongside it at the same speed. Realistic. Rain pattering, water trickling into a drain.

  為什麼有效: 不尋常的攝影機高度能讓日常主體變得有趣,而跟著主體移動的攝影機能讓它始終留在畫面中。

• 風格化的城市

  Tilt-shift miniature look, high angle over a busy city intersection at night. Cars and pedestrians stream through in toy-like motion as the traffic lights change and shop signs flicker along both sidewalks. The camera holds still. Soft city hum, distant horns.

  為什麼有效: 指定一種風格,兩個字就能改變整體畫面;固定鏡頭則讓場景中的動態來撐起整段影片。
