如何用 Arcloop 製作 AI 滑水道第一人稱影片

開場應先讓人看見落差，不必急著解釋。在這個虛構體驗裡，透明滑水道從雲層上方出發，經過一個寬闊左彎，接近青綠色泳池。鏡頭始終跟隨乘坐者，不切到外部奇觀視角。

本教學準備五張參考圖，規劃在 Arcloop 發起一次十秒請求。它不是已完成的遊樂設施模擬，也不是真實景點影像。圖片是在 Arcloop 之外生成的寫實概念參考。

逐步製作不可能的第一人稱體驗

第 1 步：設計一條觀眾能看懂的路線

只用起點、轉彎與終點。開場展示高度並露出泳池，中段維持相同側壁與藍色支撐肋，結尾從水面高度接近直接相連的泳池，不從空中掉入另一片風景。

這些是目標節奏，不保證精確時刻或物理模擬軌跡。簡單路線比多環、跳躍的迷宮更容易檢查錯誤。

第 2 步：準備五張分工不同的參考圖

參考圖 1. 乘坐入口視角：展示雲端高度、透明滑槽與可見終點

ride-entry.png

參考圖 2. 外部路線設計：單獨核對起點、左彎與泳池連接

route-design.png

參考圖 3. 乘坐彎道視角：固定向左轉彎、雙腳與藍色支撐肋

ride-bend.png

參考圖 4. 乘坐出口視角：定義滑槽與泳池水面的直接連接

ride-exit.png

參考圖 5. 滑水道材質細節：檢查透明側壁、接縫與水膜

slide-material.png

入口、彎道與出口定義乘坐者視角。外部路線圖協助檢查三者能否屬於同一條路徑。材質細節用來檢查透明側壁厚度、接縫與水。外部設計視圖和材質特寫都不應加入實際乘坐視角的生成請求。

這個區別很重要。參考圖豐富的前提是用途明確。不解釋就上傳所有角度，模型可能在中途切到滑水道外面。

參考圖生成提示詞

圖片 1: ride-entry.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. A fictional photoreal first-person action-camera still at the entrance of one transparent smooth U-shaped water slide suspended above a sunlit cloud layer. The viewer sees two bare adult feet at bottom edge, a thin water flow moving away, rounded transparent side walls with dark blue support ribs, and a distant turquoise landing pool visible through a gap in clouds below. The slide drops forward then curves gently left. Readable height and route, not an exterior drone view, no skyscraper clutter, text, logos, straps or other people.

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 transparent slide material, dark blue support ribs, clouds and distant pool. New wide exterior photographic route-design reference, showing only ONE continuous slide path from a small entry platform above the clouds through one broad banked left curve to a single turquoise pool lower down on a stable mountain terrace. The slide has no branches, loops, jumps or broken sections; supports grounded in terrace rock. No riders or people. This is a route design reference, never a request to switch a POV video to drone footage.

按此順序使用來源圖片: ride-entry.png, route-design.png.

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 adult feet, first-person camera and slide material; image 2 defines the single left-curving path to the pool. New photorealistic first-person frame in the middle of that banked curve, feet remain at lower edge, blue ribs and transparent walls continuous, turquoise destination pool still visible ahead, limited spray only at image corners. Horizon tilts modestly with bank, no inverted view, hands, external camera, jump or cut.

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 first-person adult feet, clear slide and blue ribs; image 2 for the mountain terrace pool. New first-person photographic approach frame at the end of the same slide, its chute connects directly into the turquoise pool at water level, continuous low sidewalls and visible pool edge. Pool fills most of forward view, white cloud bank and distant mountains beyond. No airborne fall, broken chute, collision, other swimmers, gore or external viewpoint. Fictional ride concept only.

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 the same slide. Macro photographic reference of a rounded clear polymer wall section joined to one dark blue structural rib, tiny realistic water beads and a thin water film, sunlight refracting softly through the material, cloud layer far below out of focus. Make the wall transparent but visibly solid with clear thickness, no glass shards, broken seam, body part, writing, embossed brand or logo. This is a material reference, not the camera framing for the whole ride.

對比三張乘坐圖中的雙腳與藍色支撐肋。轉彎方向要一致，出口要接入泳池，不能停在泳池上方。

第 3 步：向 Arcloop 請求一段連續第一人稱影片

開啟 Arcloop 專案。本次只附 ride-entry.png、ride-bend.png 與 ride-exit.png。選擇 Vidu Q4 Preview、參考圖生成影片、十秒、720p、16:9。需要測試水聲與風聲時，開啟生成音訊。

將方括號檔名換成實際素材引用。每張圖引導部分路線，不是精確指定第一格、中間格或最後一格。Q4 指南 說明了參考模式及其限制。

完整影片提示詞

請求 1: 連續第一人稱滑行

Vidu Q4 Preview, 參考圖生成影片, 10 秒, 720p, 16:9. 只附以下素材: ride-entry.png, ride-bend.png, ride-exit.png.

Create one continuous ten second photorealistic first-person fictional waterslide ride, 16:9. [ride-entry.png] guides the opening height, the same two adult bare feet at the lower edge, transparent rounded U-shaped slide walls and dark-blue support ribs above clouds. [ride-bend.png] guides ONE broad left-banked turn, not a cut to a separate location. [ride-exit.png] guides the final destination: the same chute connected directly into one turquoise pool on a mountain terrace. Start at the already-visible drop, pool glimpsed below. First two seconds begin moving forward with a thin water film. Seconds two to eight follow the continuous left curve, modest horizon bank, clouds passing outside, a little spray at corners but the route remains visible. Seconds eight to ten approach the connected pool at water level and slow the apparent motion slightly. Remain at the rider's eye position throughout. Feet retain size and position relative to camera. No drone view, reverse angle, cuts, loop, teleport, branches, inverted turn, jump, broken chute, airborne fall, collision, other person, text, logo, cartoon or music. Soft rush of water and wind, no scream or dialogue. Duration beats are targets; this is a fictional impossible ride, not footage of a real attraction.

第 4 步：確認生成前檢查任務摘要

核對模型、三張指定圖片、時長、比例、解析度、音訊設定與積分估算。不要把任務稱為首格加尾格生成；三張圖不是這樣使用的。

先生成簡單路線。外部設計與材質圖留在旁邊供檢查，如果輸入已經清楚，就不必再加入任務。

第 5 步：檢查視角、連續性與終點接近方式

正常速度看，是否一直坐在同一位置？再暫停看入口、彎道與出口。雙腳大小要穩定，藍色支撐肋要連接滑槽，泳池應沿看得懂的方向逐漸靠近。

突然出現空拍鏡頭、新岔路、斷裂側壁或瞬移終點，都不合格。路線不清時，先降速、減緩彎道，再增加炫技動作。水花不能遮滿畫面，把路徑藏起來。

單獨檢查聲音，使用克制的流水與風聲，不要全程尖叫。在剪輯軟體裡只做有助理解的修剪；實際有切鏡，就不要稱為連續鏡頭。成片標明為虛構 AI 遊樂體驗。

常見問題

一次連續請求能保證一鏡到底嗎？

不能。提示詞提出要求，結果仍須檢查。隱藏切鏡或變成外部角度，在本練習中仍算失敗。

不上傳外部路線圖，為什麼還要準備？

它是規劃與檢查素材，方便比較入口、轉彎和泳池，不讓模型模仿它的機位。不是每張有用的製作參考都適合加入每次生成。

可以做成直式嗎？

參考模式提供直式輸出，但應重新構圖三張乘坐圖，不要預設橫圖裁切後仍清楚。落差、雙腳與終點要同時看得懂。

這是真實設施設計或安全模擬嗎？

不是。這是不可能的視覺概念，不是工程建議或真實景點存在的證明。查看任務估算並預留重試，不保證第一條可用，也沒有固定價格。
