八個步驟,每一步都有能直接複製的提示詞。照著做完,你會有一組同一張臉的換場景照片,加上一段會動的短片。

大約需要 1~2 小時。英文提示詞標 EN,中文標 中,兩個都能用,生圖、生影片工具通常吃英文比較穩。
以下是 2026 年 10 月確認過有免費額度的工具。額度和規則常改,用之前看一下官方說明。
AI 不認得名字,只認得你描述的外觀。先把角色寫成一段固定文字,之後每一條提示詞都原封不動貼這段,不要每次重寫。
要寫的項目:年齡感、臉型、髮型和髮色、眼睛、膚色、服裝(顏色+材質+款式)、配件、體型。寫得越具體越好,「好看的女生」沒有用,「鵝蛋臉、頭頂小髮髻、兩耳銀色小耳環」才有用。
CHARACTER: [name], a [age]-year-old [woman/man], [face shape] face, [skin tone] skin, [eye shape and color] eyes, [hair color] [hair length] hair tied back in a [bun / ponytail], wearing a [color] [material] [garment], [shirt / inner layer], [accessories]. [Body type], [height impression]. No other accessories.
角色:[名字],[年齡] 歲 [女性/男性],[臉型]臉,[膚色]皮膚,[眼型與顏色]眼睛,[髮色][長度]頭髮往後綁成[髮髻/馬尾],穿 [顏色][材質][服裝],內搭 [上衣],[配件]。[體型],[身高感]。不要額外配件。
用生圖工具,把上一步的角色文字丟進去,做一張白底、多角度的角色設定圖。這張圖之後每次都要附上。
Character reference sheet on a plain white background, photorealistic, soft even studio lighting, no shadows on the background. [paste CHARACTER text here] Layout: one face close-up on the left, then full-body front view, three-quarter view, side view and back view in a row, same scale, neutral standing pose, arms relaxed. Same person, same outfit and same hairstyle in every view. No text, no logos.
白底角色設定圖,寫實風格,柔和均勻的棚燈,背景沒有陰影。 [貼上角色卡文字] 版面:左邊一張臉部特寫,右邊依序是全身正面、斜前 45 度、正側面、背面,大小比例一致,自然站姿、手放鬆。每個角度都是同一個人、同一套衣服、同一個髮型。不要文字、不要商標。
生出來先自己檢查:五個角度的髮型、衣服顏色、鈕扣、鞋子有沒有一樣。不一樣就重生,這張不對,後面全部會歪。
一張全身圖裡臉很小,AI 只能猜五官。所以另外準備:


Use the uploaded character sheet as reference. Close-up portrait of the same person, front-facing, looking straight at the camera, neutral expression, shoulders visible, plain light background, soft even light, sharp focus on the eyes. Keep the exact face, hairstyle and hair color.
Use the uploaded character sheet as reference. Two full-body views of the same outfit side by side: front view and back view, cropped at the neck so the head is not shown. Plain white background, even light, neutral standing pose. Keep the exact clothing colors, fabric, fit, shoes and body proportions.
參考上傳的角色設定圖。 ① 同一個人的正面臉部特寫,看鏡頭,表情自然,露出肩膀,淺色素背景,光線均勻,眼睛對焦清楚。臉、髮型、髮色完全不變。 ② 同一套衣服的全身正面和背面並排,從脖子以下裁切、不要露出頭。白底、光線均勻、自然站姿。衣服顏色、材質、版型、鞋子和身材比例完全不變。
每次生成都上傳臉部參考+身體參考(角色設定圖也可以一起附),再貼角色卡文字。場景圖只求乾淨:光線清楚、沒有雜物、不加濾鏡。景深、顆粒這類「電影感」留到第 6 步的影片提示詞再寫,髒的底圖動起來會一直閃。
動作的起點要先放在圖裡。例如之後要角色拿起杯子,這張圖裡手就先放在杯子旁邊。
Use the uploaded images as reference: image 1 is the face, image 2 is the outfit and body. Same person in every detail. [paste CHARACTER text here] Scene: [place], [time of day], [main light source and direction]. The character is [pose / starting position of the action], [where the character is in the frame, e.g. left third], [camera: medium shot, eye level]. Photorealistic, clean composition, natural colors, no filters, no extra people, no text.
參考上傳的圖:第 1 張是臉,第 2 張是衣服和身形,每個細節都是同一個人。 [貼上角色卡文字] 場景:[地點],[時間],[主要光源和方向]。 角色 [姿勢/動作的起始位置],位於畫面 [位置,例如左三分之一],[鏡頭:中景、平視]。 寫實、構圖乾淨、自然色、不加濾鏡、沒有其他人、沒有文字。
把新場景圖和角色卡並排,一項一項看:
| 看哪裡 | 常見跑掉 | 修法(一次只改一項) |
|---|---|---|
| 臉 | 變得太漂亮、像別人 | 重新上傳臉部特寫,加 keep the exact face |
| 髮型 | 綁髮被放下來 | 角色卡寫清楚綁法,加 hair stays tied back |
| 衣服 | 顏色變深、多口袋 | 附無頭身體參考,寫出顏色和材質 |
| 配件 | 多了耳環、眼鏡 | 加 no other accessories(本來就有的配件寫進角色卡) |
| 多人 | 每張臉都很清楚、搶戲 | 第一句寫主角是誰、站哪,其他人放景深外 |
Edit this image only. Keep the person, pose, background and lighting exactly the same. Change only: [the one thing that is wrong, e.g. make the suit the same charcoal gray as the reference / tie the hair back like the reference / remove the earrings].
只修改這張圖。人物、姿勢、背景、光線完全不變,只改:[那一個錯的地方,例如把西裝改成跟參考圖一樣的深灰色/頭髮綁回原本的髮型/拿掉耳環]。
在影片工具選「圖片轉影片」(用圖片當第一格),上傳第 4 步檢查過的那張圖。提示詞照下面的順序寫:
Photorealistic 9:16 video, 8 seconds. Use the uploaded image as the first frame. Keep the person's face, hair, outfit and position exactly as in the image. No extra people. Camera: [locked / slow push-in], eye level, shallow depth of field, subtle film grain, slight handheld feel. 0-3s: [first action]. 3-6s: [reaction: where the character looks, a short pause]. 6-8s: [small final action], then the character holds still at the end. Natural, slightly imperfect timing; blinks are irregular. Ambient sound: [room tone / street / cafe].
寫實 9:16 影片,8 秒。用上傳的圖當第一格,人物的臉、頭髮、服裝、位置都跟圖一樣,不要多出其他人。 鏡頭:[固定/慢慢推近],平視,淺景深,輕微底片顆粒,些微手持感。 0–3 秒:[第一個動作]。 3–6 秒:[反應:視線看向哪裡、停頓一下]。 6–8 秒:[最後一個小動作],結尾停住不動。 節奏自然、不要太完美,眨眼不規律。環境音:[室內/街道/咖啡廳]。
| 容易假 | 改成這樣 |
|---|---|
| 他很猶豫 | 手指停在杯緣,兩秒後才拿起來 |
| 他自然地說話 | 說完停一秒,視線移到手上 |
| 三個人在聊天 | 主角在左側清楚,其他人在景深外、臉模糊 |
Continue from the uploaded image, which is the last frame of the previous clip. Use it as the first frame. The second uploaded image is the face reference: keep the same face, hair and outfit. Photorealistic 9:16, 8 seconds, same lighting and camera position as the first frame. 0-3s: [next action]. 3-6s: [reaction]. 6-8s: [ending], the character holds still.
接續上傳的圖(上一段的最後一格),把它當第一格。第二張上傳的圖是臉部參考:臉、頭髮、服裝都保持一樣。 寫實 9:16,8 秒,光線和鏡頭位置跟第一格相同。 0–3 秒:[下一個動作]。3–6 秒:[反應]。6–8 秒:[結尾],停住不動。
不要只播一遍覺得「好像可以」。在剪輯軟體裡一格一格拉,對著角色卡看:
只有中間一小段壞掉,可以把壞掉前的那一格截下來當起始圖,只重做那幾秒,不用整支重來。
同一套流程實際走一遍,你可以直接照抄,換成自己的角色就好。
① 角色卡文字
CHARACTER: an East Asian man in his early 30s, oval face with a defined jaw, light warm skin, dark brown narrow eyes, straight thick eyebrows, short mustache and chin stubble, black shoulder-length hair pulled back into a small topknot with loose strands at the sides, small silver hoop earrings in both ears, wearing a loose charcoal-gray double-breasted suit jacket and matching wide trousers, a dark gray zip-up high-neck top underneath, black shoes. Slim build, average height. No other accessories.
② 角色設定圖、臉和身體參考:把上面這段貼進第 2、3 步的提示詞,做出角色卡、臉部特寫、無頭全身。
③ 場景圖
Use the uploaded images as reference: image 1 is the face, image 2 is the outfit and body. Same person in every detail. CHARACTER: an East Asian man in his early 30s, oval face with a defined jaw, light warm skin, dark brown narrow eyes, straight thick eyebrows, short mustache and chin stubble, black shoulder-length hair pulled back into a small topknot with loose strands at the sides, small silver hoop earrings in both ears, wearing a loose charcoal-gray double-breasted suit jacket and matching wide trousers, a dark gray zip-up high-neck top underneath, black shoes. Slim build, average height. No other accessories. Scene: a quiet cafe by a large window, late afternoon, warm sunlight coming from the left. He sits at a small wooden table on the left third of the frame, a white coffee cup in front of her, his phone lying face down next to the cup, his right hand resting near the phone. Medium shot, eye level. Photorealistic, clean composition, natural colors, no filters, no extra people, no text.
④ 檢查:西裝是不是深灰雙排扣、頭頂髮髻和兩側散髮還在不在、銀色小耳環有沒有消失。這三點最常跑。
⑤ 8 秒短片
Photorealistic 9:16 video, 8 seconds. Use the uploaded image as the first frame. Keep the man's face, topknot, earrings, charcoal suit and position exactly as in the image. No extra people. Camera: locked, eye level, shallow depth of field, subtle film grain. 0-3s: the phone screen lights up; his eyes move to it first, then he turns it over with his right hand. 3-6s: he reads it, pauses for about one second, and the corner of his mouth rises slightly. 6-8s: he places the phone back on the table and looks out of the window, then holds still. Natural, slightly imperfect timing; blinks are irregular. Ambient sound: quiet cafe.
寫實 9:16 影片,8 秒。用上傳的圖當第一格,男生的臉、頭頂小髮髻、耳環、深灰西裝和位置都跟圖一樣,不要多出其他人。 鏡頭:固定,平視,淺景深,輕微底片顆粒。 0–3 秒:手機螢幕亮起,他先用眼睛看過去,再用右手把手機翻過來。 3–6 秒:他看著訊息,停頓大約一秒,嘴角微微上揚。 6–8 秒:他把手機放回桌上,轉頭看向窗外,然後停住不動。 節奏自然、不要太完美,眨眼不規律。環境音:安靜的咖啡廳。
⑥ 想接第二段:存下最後一格(他看著窗外),用第 7 步的提示詞,動作寫「他拿起杯子喝一口,起身扣好西裝外套」。
發出去之前,一項一項打勾。
