如何為 Grok Video 撰寫提示詞

最重要的規則

1. 1

   依順序描述一個鏡頭

   先寫鏡頭類型和角度,再寫動作並用「然後」連接,接著是場景、光線、風格描述和聲音。短片只容得下一、兩個節拍,放不下一整個故事。

2. 2

   最後寫聲音

   每支影片都會附帶配樂。請把聲音寫在最後:雨打在柏油路上、人群的低語、一個緩慢的鋼琴音。

3. 3

   不要寫對白

   Mage 上的 Grok Video 不會讓嘴型對上語音。需要角色說話時,請使用 Cherry 2 Pro 或 Lemon。

4. 4

   每個參考只負責一件事

   「@image1 裡的女子穿著 @image2 的大衣,走過整座碼頭。」兩、三個角色分明的參考,勝過五個互相重疊的參考。

5. 5

   一次只編輯一個地方

   上傳片段,說明唯一要改的地方,再列出要保留的內容:「其他一切都要與原片完全一致,包括她的臉、手、姿勢和背景。」

可以參考的提示詞

• 建立場景的鏡頭

  Aerial wide shot of a small fishing harbor at dawn. A single red ferry pulls away from the pier, then turns slowly toward the open sea, leaving a long white wake across the still water. Stacked lobster traps, a row of pastel houses on the hill, gulls circling the masts. Soft pink light low on the horizon, mist over the water. Calm documentary feel. The ferry's diesel hum, gull cries, water lapping at the pilings.

  為什麼有效: 依序寫下角度、連續動作、場所、光線、氛圍和聲音:一個清楚的鏡頭,不留任何需要猜測的地方。

• 慢動作的產品特寫時刻

  Extreme slow-motion macro shot: the cap flips off a cold green glass bottle of lemon soda, then a fine spray of droplets bursts into the air and a thin mist curls out of the neck. Condensation runs down the glass; ice glitters in a metal bucket behind it. Bright summer backlight, sharp highlights on every droplet. Fresh commercial look. A crisp pop, the fizz of bubbles, a short splash.

  為什麼有效: 慢動作加上微距鏡頭,讓短短的片段也有足夠的內容可看,而聲音那一行則點出每個動作。

• 靜止不動的微縮場景

  Stop-motion claymation, visible fingerprints in the clay, slightly choppy frame rate, a small tabletop set. A round clay hedgehog in a blue apron waters three potted sunflowers on a windowsill, then sets down the watering can and watches as the flowers slowly lift their heads toward the sun. A checkered curtain, a cracked teapot and a sleeping clay cat sit beside the pots. Continuity: every object stays exactly where it is for the whole clip; nothing appears, disappears, duplicates, or changes shape. Warm morning window light, cozy handmade look, a gentle ukulele melody and the trickle of water.

  為什麼有效: 連貫性的句子能避免道具變多或亂跑,這正是繁複場景中最常見的瑕疵。

• 穿著已儲存服裝的你的 Character

  Slow push-in on a rooftop garden at golden hour. Then @mara walks in from the left between the planters, wearing @linen-shirt with wide white trousers, stops at the railing and looks out over the city, then turns her head toward the camera with a small smile. Warm low sun behind her, the skyline soft and hazy. High-quality slow motion, highly detailed face. Wind in the leaves, distant traffic, a soft acoustic guitar.

  為什麼有效: 先寫運鏡,每個代號只負責一個角色,提示詞描述的是它們的動作,而不是圖片的內容。請把代號換成你自己的 Character 和 Reference。

• 編輯你自己的片段

  Make the woman's raincoat bright yellow. Keep everything else exactly as in the original, including her face, hands, pose, the umbrella, and the background.

  為什麼有效: 將片段上傳為「影片」:只要一項修改,再加上要保留內容的清單,就足以完成編輯。
