目的
此技能為 Claude Code 和 AI 編碼代理提供全面的背景知識,以使用 Remotion 建構可投入生產的影片。其中涵蓋了設計原則、精心挑選的範本以及最佳實務。
使用時機
在以下情況下使用此技能:
- 使用 React 以程式方式創建影片內容
- 建構 Podcast 音頻圖或音訊視覺化
- 為影片加入動畫字幕(TikTok/Reels 風格)
- 創建 3D 產品展示
- 建構影片生成 SaaS
- 製作數據視覺化影片
- 大規模生成社群媒體內容
影片設計原則
1. 節奏與韻律
- 快速剪輯:1-2 秒,充滿活力(社群媒體)
- 中等節奏:3-5 秒,便於理解(教學)
- 慢節奏:5-10 秒,強調效果(電影感)
- 匹配音訊:將轉場與節拍/語音同步
2. 視覺層級
- 每個畫面一個焦點
- 使用動態引導注意力
- 對比重要元素
- 保持一致間距
3. 影片文字規則
- 每個畫面最多 7 個單字
- 高對比度(淺色文字配深色背景,或加上輪廓)
- 文字在螢幕上停留時間足夠閱讀 2 次
- 放置於下方三分之一處或中央
- 避免靠近邊緣(安全區域:10% 邊距)
4. 動畫時機
| 元素 | 持續時間 | 緩動函數 |
|---|---|---|
| 文字出現 | 8-15 影格 | easeOut |
| 文字退出 | 6-10 影格 | easeIn |
| 場景轉場 | 15-30 影格 | easeInOut |
| Logo 揭示 | 30-60 影格 | spring |
| 快速切換 | 0-3 影格 | linear |
5. 影格率
- 30fps:標準影片,社群媒體
- 60fps:流暢動態,遊戲內容
- 24fps:電影感
- 25fps:歐洲廣播標準
6. 畫面比例
| 平台 | 比例 | 解析度 |
|---|---|---|
| YouTube | 16:9 | 1920x1080 |
| TikTok/Reels | 9:16 | 1080x1920 |
| Instagram Feed | 1:1 | 1080x1080 |
| Instagram Story | 9:16 | 1080x1920 |
| 16:9 | 1280x720 | |
| 16:9 | 1920x1080 |

Root.tsx 範本
import { Composition } from 'remotion';
import { Main } from './compositions/Main';
export const RemotionRoot = () => {
return (

核心模式
動畫基礎
import { useCurrentFrame, useVideoConfig, interpolate, spring } from 'remotion';
const frame = useCurrentFrame();
const { fps, width, height, durationInFrames } = useVideoConfig();
// 線性插值(固定範圍)
const opacity = interpolate(frame, [0, 30], [0, 1], {
extrapolateRight: 'clamp'
});
// 彈簧動畫(有彈性)
const scale = spring({
frame,
fps,
config: { damping: 12, stiffness: 200 }
});
// 延遲彈簧
const delayedScale = spring({
frame: frame - 15, // 15 影格延遲
fps,
config: { damping: 10 }
});
序列編排
import { Sequence, AbsoluteFill } from 'remotion';
export const MyVideo = () => (
<AbsoluteFill>
<Sequence from={0} durationInFrames={60}>
<Intro />
</Sequence>
<Sequence from={60} durationInFrames={120}>
<MainContent />
</Sequence>
<Sequence from={180}>
<Outro />
</Sequence>
</AbsoluteFill>
);
文字動畫
const TextReveal = ({ text }: { text: string }) => {
const frame = useCurrentFrame();
const words = text.split(' ');
return (
<div style={{ display: 'flex', gap: 10, justifyContent: 'center' }}>
{words.map((word, i) => {
const delay = i * 5;
const opacity = interpolate(frame - delay, [0, 10], [0, 1], {
extrapolateLeft: 'clamp',
extrapolateRight: 'clamp'
});
const y = interpolate(frame - delay, [0, 10], [20, 0], {
extrapolateLeft: 'clamp',
extrapolateRight: 'clamp'
});
return (
<span key={i} style={{ opacity, transform: `translateY(${y}px)` }}>
{word}
</span>
);
})}
</div>
);
};
音訊同步
import { Audio, useCurrentFrame, interpolate } from 'remotion';
import { getAudioDurationInSeconds } from '@remotion/media-utils';
// 音量包絡
const frame = useCurrentFrame();
const volume = interpolate(frame, [0, 30, 270, 300], [0, 1, 1, 0]);
<Audio src={staticFile('music.mp3')} volume={volume} />
