奇特材質能吸引注意，但清楚的接觸點才能讓動作有分量。本例使用內部微微發光的雲朵形麵包。外皮、砧板與刀保持一般材質，超現實細節只出現在內部。
下方五張參考圖與提示詞是 Arcloop 製作方案，不是已完成的音訊實測。發光是虛構視覺效果，不代表真實麵包或可食用產品的特性。圖片由 Arcloop 之外的內建圖片工具製作。
逐步製作有觸感的 ASMR 場景
第 1 步：把驚喜限制為一種材質變化
不要同時加入發光麵包、漂浮工具、變化背景與環繞運鏡。保持深色砧板、米色背景與柔光。觀眾應看清刀刃在哪裡接觸、外皮何時裂開，以及切面露出什麼。
| 請求 | 時長 | 動作與聲音 |
|---|---|---|
| 切割 | 12 秒 | 緩慢切一次，外皮輕響，切片隨後落穩 |
| 細節 | 4 秒 | 安靜展示切面，少量碎屑落定 |
兩個請求預計剪成 16 秒。時間描述目標節奏，不代表精確控制每個影格。
第 2 步：分開準備完整麵包、工具與內部材質
參考圖 1. 完整雲朵麵包：固定輪廓、外皮、砧板與光線
whole-loaf.png
參考圖 2. 刀具與握姿：明確指定刀刃形狀和手部位置
knife-reference.png
參考圖 3. 下刀起始圖：讓切割從完整麵包開始
cut-start.png
參考圖 4. 內部材質參考：定義微光氣孔與切面，不作為開場狀態
interior-material.png
參考圖 5. 微距紋理參考：檢查疏鬆組織、外皮與少量碎屑
crumb-detail.png
完整麵包圖固定輪廓與外皮。刀具圖明確指定握姿與刀刃形狀。起始姿勢固定下刀位置，切面圖定義虛構內部，微距圖展示結尾應看清的紋理。
切面是目標材質，不是開場狀態。如果一開始麵包已切開，就失去兩者區別。請求中要分清完整麵包與最終材質的角色。
參考圖生成提示詞
圖片 1: whole-loaf.png
不附參考圖，生成新圖片。
Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Photoreal tactile studio food reference. One small original bread loaf shaped like a soft three-lobed cloud, a gently browned matte crust dusted lightly with flour, on a flat unmarked charcoal stone cutting board. Pale beige background, warm soft side light, clear cast shadow, realistic flour and pores. Whole loaf intact with no cut or knife, no face, hands, lettering, packaging or glow. A believable food prop for a surreal visual effect, landscape close-up.

Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Realistic close photographic reference of one plain stainless serrated bread knife with a dark unmarked handle, held in a natural adult right hand above an empty flat charcoal stone board. Blade points away from the hand, fingers correctly wrapped around handle, no contact with skin. Warm soft side lighting and beige background. No bread, second hand, blood, logos, engraving or writing; complete blade and gripping fingers visible.

Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Image 1 defines the intact three-lobed loaf, stone board and lighting. Image 2 defines knife and natural gripping hand. Create a matching photographic opening keyframe of the serrated blade just touching the top crust at the right third of the loaf, before a slice separates. One hand holding handle; no other hand near blade, no duplicate knife. Preserve whole loaf silhouette, board position, beige backdrop and material texture. No magical effect yet.

Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Use image 1 for loaf shape, lightly browned crust, charcoal board, beige backdrop and warm side light. New conceptual material reference: the right third has been cut away as one intact slice beside the larger loaf; cross-section has delicate white aerated bread crumb with a very faint cool glow deep inside, like luminous mist caught in pores. The outer crust remains real bread. No liquid spill, sparks, sky landscape or second loaf; no knife or hands. An intentionally surreal food visualization, not real edible product evidence.

Use case: photorealistic-natural. Asset type: original video production reference. One coherent photographic frame, landscape 16:9 unless a different ratio is specified. Real material texture, believable lighting and scale. No text, captions, logos, watermark, UI, illustration or cartoon. Use image 1 for exact invented bread interior and crust. Extreme macro photographic crop of the cut edge, showing small aerated pores, subtle pale light from deep crumb, thin floury crust and a few crumbs touching the charcoal board. The surface is porous food, not plastic, cotton candy, glass or foam rubber. Keep warm side light and cool faint internal light distinct. No hands, knife, captions or extra objects. This is a material close-up reference.
檢查靜圖中的手。多餘手指、刀刃穿過刀柄，或另一隻手靠近刃口，都需要修正。提示詞寫得仔細，也不能保留明顯錯誤的姿勢。
第 3 步：只安排一次切割，說明接觸時的聲音
在 Arcloop 專案中，附上切割請求指定的四張參考圖。選擇 Vidu Q4 Preview、參考圖生成影片、十二秒、720p、16:9，並開啟生成音訊。將方括號檔名換成實際上傳素材引用。
提示詞先要求輕微外皮碎裂聲，再是更輕的壓縮聲，不是無論畫面發生什麼都持續大聲碎響。細節請求使用自己的起始圖，選擇圖片轉影片、四秒、720p。
完整影片提示詞
請求 1: 切割
Vidu Q4 Preview, 參考圖生成影片, 12 秒, 720p, 16:9. 只附以下素材: whole-loaf.png, knife-reference.png, cut-start.png, interior-material.png.
Create one continuous twelve second photorealistic surreal food ASMR shot. [whole-loaf.png] defines one intact three-lobed cloud-shaped bread loaf, matte lightly browned floury crust, charcoal stone board and beige studio backdrop. [knife-reference.png] defines one plain serrated bread knife and one natural adult right hand holding its handle safely. [cut-start.png] defines composition before the slice separates, not a second loaf. [interior-material.png] defines only the invented final cross-section: airy white bread crumb with a faint cool glow deep in the pores. Begin with the intact loaf. First two seconds hold the blade touching its right third. Over the next seven seconds make ONE slow believable sawing cut through bread, one hand on the handle, no fingers near the blade. Over the final three seconds let the one cut slice settle a small distance to the right, exposing the pale luminous crumb. Outer crust and board stay unchanged. Fixed close camera, warm side light, visible contacts, no cuts. Sound: soft crust crackle followed by quieter crumb compression, low background noise, no speech or music. No extra knife, second loaf, liquid spill, sparks, body injury, text, logos, cartoon, dramatic camera movement or explosive glow. The glowing interior is a fictional visual effect, not a real product claim.
請求 2: 細節
Vidu Q4 Preview, 圖片轉影片, 4 秒, 720p, 16:9. 只附以下素材: crumb-detail.png.
Use [crumb-detail.png] as the only starting frame. One four second photorealistic macro ASMR detail of the same cut cloud bread, thin crust and porous faintly luminous crumb above the charcoal board. Camera stays still; only a few tiny already-visible crumbs settle gently onto the board. No new cut or new slice, hands, knife, smoke, liquid or added objects. Preserve porous texture rather than changing it to plastic or glass. Very faint dry crumb sounds and quiet studio ambience, no music, voice, text, logo or animation. An editorial close detail after a separate cutting shot; a seamless match is not guaranteed.
Q4 工作流程 的生成音訊是選用項目。支援聲音，不代表成片切割聲一定準確同步。
第 4 步：分別檢查畫面與聲音
確認前檢查參考圖與積分估算。先生成切割，靜音看一次：是否只有一把刀、一個麵包與一次切割？刀完全通過前，切片是否仍相連？外皮材質有沒有改變？
再閉眼聽一次。安靜部分要為接觸聲留空間，最後聲畫一起檢查。刀還沒碰到麵包就出現響亮裂聲，即使音色好聽也是時序錯誤。
內部變成天空風景時，簡化為微弱發光的疏鬆麵包組織。切片飛離砧板時，減少位移，只讓它落穩在旁邊。
第 5 步：完成細節鏡頭，不用轉場掩蓋錯誤
切面材質合格後再生成細節。在剪輯軟體中對齊顏色、砧板與方向。直接切鏡有時比疊化更好，後者可能讓兩把刀或兩道外皮重疊。
生成聲音太晚或太大聲時，用自己製作或已授權的音訊替換、對齊。這是外部後製步驟，不代表 Arcloop 內提供精確音訊編輯。未檢查首尾畫面與音訊邊界前，不要稱為無縫循環。
常見問題
必須實拍一次切麵包嗎？
這套圖片參考方案不需要。圖片定義預定握姿與動作。本文未錄製真實切割示範，生成手部仍需檢查。
可以換成其他材質變化嗎？
可以。完整物體與切面一起更換，再選一個能揭示差異的動作。分清虛構效果與真實產品特性。
有生成音訊就能保證 ASMR 好聽嗎？
不能。檢查雜訊、刺耳聲、重複點擊與接觸時序。必要時調音量或換用授權聲音。是否悅耳需要聆聽判斷，不是模型開關。
哪些因素影響預算？
模型、兩段時長、解析度、音訊設定、參考圖準備與重試。以 Arcloop 目前估算為準，不預設固定費用或觀眾反應。
