用 Seedance 2.5 和三張參考圖,做一支一鏡到底的產品影片
在 Pixocto 使用 Seedance 2.5,將人物、商品與場景三張參考圖串成一支 15 秒直式產品影片,並附可修改的提示詞。
用 Seedance 2.5 和三張參考圖,做一支一鏡到底的產品影片
這次用 Seedance 2.5 做一支一鏡到底的產品影片:人物、商品與場景各用一張參考圖,再用一個連續動作把它們接起來。減少切換,才能看清同一個人、同一件商品與同一個房間是否一直保持一致。
以下以橘白色軟管防曬乳為練習。分鏡與提示詞是創作範本,不是現成影片的原始提示詞,也不代表已驗證的生成結果。
每張圖只負責一件事
| 上傳順序 | 參考圖 | 要保留的內容 |
|---|---|---|
| 圖片 1 | 人物正面照 | 臉、髮型、膚色與服裝 |
| 圖片 2 | 商品正面照 | 軟管外形、橘白配色、瓶蓋與標籤位置 |
| 圖片 3 | 房間一角 | 窗戶、桌子、光線方向與背景擺設 |
人物照應清楚露臉;商品照應完整呈現正面;場景照則要留出人物站立和商品擺放的空間。這三張圖是各自獨立的參考,不是依序播放的三個畫面。
在 Pixocto 的 Seedance 2.5 工作台選擇「參考圖」,依照表格順序上傳。Seedance 2.5 目前支援最長 30 秒、最多 30 張參考圖;這次練習只用三張圖與 15 秒,讓人物、包裝與空間各有明確任務。詳見模型頁面。請使用參考圖模式,而非「首幀」模式。
用一個動作連接三張圖
人物站在參考場景的窗邊,商品放在桌上。鏡頭先交代人物與空間,再跟著她拿起商品,最後停在商品正面。整段不換房間、不換人物,也不切第二個角度。
設定 9:16、15 秒。下方英文提示詞依上傳順序描述第一、第二、第三張圖片;Seedance 2.5 會將它們當作參考素材,不需輸入特殊圖片標記。更換商品時,把軟管外形、顏色與瓶蓋描述改成實際包裝。
可直接修改的提示詞
Create a 15-second vertical 9:16 single-take lifestyle product video. Use the three uploaded images as separate reference roles, not as storyboard frames to cut between.
REFERENCE ROLES
The first uploaded image is the character reference: one adult woman in a cream knit top. Keep the same face, hairstyle, skin tone, outfit, and body proportions throughout.
The second uploaded image is the product reference: one orange-and-white sunscreen tube. Preserve its silhouette, color blocks, white cap, proportions, and front-label layout. Do not invent brand text or product claims.
The third uploaded image is the setting reference: a warm apartment window corner with a small table. Keep the window shape, table position, late-afternoon sunlight, and background arrangement consistent.
ONE CONTINUOUS SHOT
00:00–00:04 — Medium shot of the woman beside the window. The tube is standing on the table. Natural handheld framing.
00:04–00:09 — Without a cut, she reaches for the same tube and lifts it. Her hand moves naturally around the package.
00:09–00:13 — She turns the front of the tube toward the camera once. The camera moves slightly closer while her face stays visible behind the product.
00:13–00:15 — Hold the final composition: the tube is sharp and upright in the foreground, the same woman and window remain behind it. End with a clean cut.
AUDIO AND FINISH
Quiet room tone and subtle handling sounds. No spoken claims, music, subtitles, on-screen text, or added logos. Natural skin and fabric texture.
AVOID
No jump cuts, extra people, duplicated tube, changed cap, warped fingers, floating objects, changing room, changing daylight, or newly invented packaging copy.
先檢查連續性,再調整美感
在拿起商品和商品靠近鏡頭的兩個位置暫停:人物是否換臉或換衣?手上的軟管是否仍是桌上那一支?窗戶和桌子有沒有突然移位?若出現問題,先縮短運鏡與手部動作,再考慮轉場或特效。
正式使用前,還要逐格核對品牌、成分與功效文字。若生成文字不準,剪輯時改用已核對的商品實拍特寫,不要把模型猜出的字當作真實包裝。
