這個單元在做什麼

\n

00:07這個單元要做一隻奇怪的魚。背景是用噪聲做出來、一直往前流動的水，再合成不同的圖片素材。魚用數據控制，包括滑鼠的位置和噪聲產生的亂數，讓牠在畫面裡游來游去。

\n

00:41一路做下來，會用到 TOP 最常用的幾件事：用 Over 和 Composite 疊圖，用 Ramp 和 Noise 做背景，用 Displace 扭曲，用 Switch 切換素材，用 Feedback 留下殘影，最後加上模糊、文字和勾線，再做一個控制魚大小的滑桿。哲宇說，學完這個單元，可以想像「你學會了 Premiere 加 Photoshop」，把很多不同格式的影音材料混在一起，做出屬於自己的獨特拼貼動畫。

\n

08:08做的過程中，哲宇提醒一個原則：「我們在寫 TD 的時候有一個原則，我們希望每個步驟盡可能清楚、明確的出現在畫面上面。」所以數字不藏在輸入框裡，用 Math 換範圍，用 Rename 幫頻道取看得懂的名字。
