名称: 弹簧动画 描述: Remotion弹簧物理用于动态图形视频制作。弹性入场、弹性轨迹、编排序列、物理预设以及单纯使用interpolate()无法实现的有机运动模式。 元数据: 标签: 弹簧, remotion, 动态图形, 动画, 视频, 物理, 弹跳, 弹性, 轨迹, 错开

何时使用

在创建需要弹簧物理的Remotion视频合成时使用此技能——自然的、有机的运动，带有弹跳、过冲和弹性稳定。

当您需要时使用弹簧:

  • 弹跳/弹性入场（过冲 + 稳定）
  • 有机减速（不是线性，不是缓动——物理建模）
  • 带有弹簧物理的错开轨迹每个元素
  • 数字计数器过冲然后稳定
  • 缩放/旋转带有自然重量和惯性
  • 入场 + 退场动画带有弹簧数学（进 - 出）
  • 多属性编排每个属性不同的弹簧配置

当以下情况时使用Remotion原生interpolate():

  • 线性或缓动运动无弹跳（淡入淡出、滑动、擦拭）
  • 精确时间控制（必须在帧N精确结束）
  • 剪辑路径动画
  • 进度条 / 确定性计数器

当以下情况时使用GSAP（gsap-animation技能）:

  • 文本拆分（SplitText: 字符/单词/行带有遮罩）
  • SVG笔画绘制（DrawSVG）
  • SVG变形（MorphSVG）
  • 复杂时间线编排带有标签和位置参数
  • 混排文本解码效果
  • 注册可重用效果

注意: @react-spring/web与Remotion不兼容（它在内部使用requestAnimationFrame）。此技能使用Remotion的原生spring()函数，以帧确定性的方式提供相同的物理模型。

核心API

spring()

基于弹簧物理模拟返回一个从0到1的值（在低阻尼下可以过冲超过1）。

import { spring, useCurrentFrame, useVideoConfig } from 'remotion';

const frame = useCurrentFrame();
const { fps } = useVideoConfig();

const value = spring({
  frame,
  fps,
  config: {
    damping: 10,     // 1-200: 更高 = 更少弹跳
    stiffness: 100,  // 1-200: 更高 = 更快快照
    mass: 1,         // 0.1-5: 更高 = 更多惯性
  },
});

配置参数

参数 范围 默认值 效果
damping 1-200 10 阻力。低 = 弹跳，高 = 平滑
stiffness 1-200 100 快照速度。高 = 快，低 = 慢
mass 0.1-5 1 重量/惯性。高 = 迟钝，低 = 轻快
overshootClamping 布尔 false 在目标处钳制（无过冲）

附加选项

选项 类型 效果
delay 数字 延迟开始N帧（延迟结束前返回0）
durationInFrames 数字 强制弹簧在N帧内稳定
reverse 布尔 从1到0动画
from 数字 起始值（默认0）
to 数字 结束值（默认1）

measureSpring()

计算弹簧配置需要多少帧来稳定。对于<Sequence>和合成持续时间至关重要。

import { measureSpring } from 'remotion';

const frames = measureSpring({
  fps: 30,
  config: { damping: 10, stiffness: 100 },
}); // => 稳定前的帧数

物理预设

// src/spring-presets.ts
import { SpringConfig } from 'remotion';

export const SPRING = {
  // 平滑，无弹跳——微妙揭示，背景运动
  smooth: { damping: 200 } as Partial<SpringConfig>,

  // 快照，最小弹跳——UI元素，干净入场
  snappy: { damping: 20, stiffness: 200 } as Partial<SpringConfig>,

  // 弹跳——活泼入场，吸引注意力
  bouncy: { damping: 8 } as Partial<SpringConfig>,

  // 重，慢——戏剧性揭示，重量物体
  heavy: { damping: 15, stiffness: 80, mass: 2 } as Partial<SpringConfig>,

  // 摇摆——弹性，卡通式过冲
  wobbly: { damping: 4, stiffness: 80 } as Partial<SpringConfig>,

  // 僵硬——快速快照带微小弹跳
  stiff: { damping: 15, stiffness: 300 } as Partial<SpringConfig>,

  // 温和——慢，梦幻，有机
  gentle: { damping: 20, stiffness: 40, mass: 1.5 } as Partial<SpringConfig>,

  // 糖浆——非常慢，重，几乎不弹跳
  molasses: { damping: 25, stiffness: 30, mass: 3 } as Partial<SpringConfig>,

  // 弹出——强过冲用于缩放效果
  pop: { damping: 6, stiffness: 150 } as Partial<SpringConfig>,

  // 橡胶——夸张弹性弹跳
  rubber: { damping: 3, stiffness: 100, mass: 0.5 } as Partial<SpringConfig>,
} as const;

1. 弹簧入场模式

基本弹簧入场

import { spring, interpolate, useCurrentFrame, useVideoConfig, AbsoluteFill } from 'remotion';
import { SPRING } from './spring-presets';

const SpringEntrance: React.FC<{
  children: React.ReactNode;
  preset?: keyof typeof SPRING;
  delay?: number;
}> = ({ children, preset = 'bouncy', delay = 0 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const progress = spring({ frame, fps, delay, config: SPRING[preset] });
  const translateY = interpolate(progress, [0, 1], [60, 0]);

  return (
    <AbsoluteFill style={{
      opacity: progress,
      transform: `translateY(${translateY}px)`,
    }}>
      {children}
    </AbsoluteFill>
  );
};

缩放弹出

const ScalePop: React.FC<{
  children: React.ReactNode;
  delay?: number;
}> = ({ children, delay = 0 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  // pop 预设过冲超过1，创造自然缩放弹跳
  const scale = spring({ frame, fps, delay, config: SPRING.pop });
  const opacity = spring({ frame, fps, delay, config: SPRING.smooth });

  return (
    <div style={{
      transform: `scale(${scale})`,
      opacity,
    }}>
      {children}
    </div>
  );
};

入场 + 退场（弹簧数学）

const EnterExit: React.FC<{
  children: React.ReactNode;
  enterDelay?: number;
  exitBeforeEnd?: number; // 在合成结束前开始退场的帧数
}> = ({ children, enterDelay = 0, exitBeforeEnd = 30 }) => {
  const frame = useCurrentFrame();
  const { fps, durationInFrames } = useVideoConfig();

  const enter = spring({ frame, fps, delay: enterDelay, config: SPRING.bouncy });
  const exit = spring({
    frame, fps,
    delay: durationInFrames - exitBeforeEnd,
    config: SPRING.snappy,
  });

  const scale = enter - exit; // 0 -> 1 -> 0
  const opacity = enter - exit;

  return (
    <div style={{ transform: `scale(${scale})`, opacity }}>
      {children}
    </div>
  );
};

2. 轨迹 / 错开模式

弹簧轨迹（错开入场）

模仿React Spring的useTrail——每个元素以帧延迟入场。

const SpringTrail: React.FC<{
  items: React.ReactNode[];
  staggerFrames?: number;
  preset?: keyof typeof SPRING;
  direction?: 'up' | 'down' | 'left' | 'right';
}> = ({ items, staggerFrames = 4, preset = 'bouncy', direction = 'up' }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const getOffset = (progress: number) => {
    const distance = 50;
    const remaining = interpolate(progress, [0, 1], [distance, 0]);
    switch (direction) {
      case 'up': return { transform: `translateY(${remaining}px)` };
      case 'down': return { transform: `translateY(${-remaining}px)` };
      case 'left': return { transform: `translateX(${remaining}px)` };
      case 'right': return { transform: `translateX(${-remaining}px)` };
    }
  };

  return (
    <>
      {items.map((item, i) => {
        const delay = i * staggerFrames;
        const progress = spring({ frame, fps, delay, config: SPRING[preset] });
        return (
          <div key={i} style={{ opacity: progress, ...getOffset(progress) }}>
            {item}
          </div>
        );
      })}
    </>
  );
};

字符轨迹（文本动画）

手动字符拆分带弹簧错开。对于高级文本拆分（遮罩揭示，行包装），使用gsap-animation技能代替。

const CharacterTrail: React.FC<{
  text: string;
  staggerFrames?: number;
  preset?: keyof typeof SPRING;
  fontSize?: number;
}> = ({ text, staggerFrames = 2, preset = 'pop', fontSize = 80 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  return (
    <div style={{ display: 'flex', justifyContent: 'center', overflow: 'hidden' }}>
      {text.split('').map((char, i) => {
        const delay = i * staggerFrames;
        const progress = spring({ frame, fps, delay, config: SPRING[preset] });
        const translateY = interpolate(progress, [0, 1], [fontSize, 0]);

        return (
          <span key={i} style={{
            display: 'inline-block',
            fontSize,
            fontWeight: 'bold',
            color: '#fff',
            opacity: progress,
            transform: `translateY(${translateY}px)`,
            whiteSpace: 'pre',
          }}>
            {char === ' ' ? '\u00A0' : char}
          </span>
        );
      })}
    </div>
  );
};

单词轨迹

const WordTrail: React.FC<{
  text: string;
  staggerFrames?: number;
  preset?: keyof typeof SPRING;
  fontSize?: number;
}> = ({ text, staggerFrames = 5, preset = 'bouncy', fontSize = 64 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();
  const words = text.split(' ');

  return (
    <div style={{ display: 'flex', flexWrap: 'wrap', gap: '0.3em', justifyContent: 'center' }}>
      {words.map((word, i) => {
        const delay = i * staggerFrames;
        const progress = spring({ frame, fps, delay, config: SPRING[preset] });
        const scale = spring({ frame, fps, delay, config: SPRING.pop });

        return (
          <span key={i} style={{
            display: 'inline-block',
            fontSize,
            fontWeight: 'bold',
            color: '#fff',
            opacity: progress,
            transform: `scale(${scale})`,
          }}>
            {word}
          </span>
        );
      })}
    </div>
  );
};

网格错开（中心向外）

const GridStagger: React.FC<{
  items: React.ReactNode[];
  columns: number;
  cellSize?: number;
  gap?: number;
}> = ({ items, columns, cellSize = 120, gap = 16 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();
  const rows = Math.ceil(items.length / columns);
  const centerCol = (columns - 1) / 2;
  const centerRow = (rows - 1) / 2;

  return (
    <div style={{
      display: 'grid',
      gridTemplateColumns: `repeat(${columns}, ${cellSize}px)`,
      gap,
    }}>
      {items.map((item, i) => {
        const col = i % columns;
        const row = Math.floor(i / columns);
        // 从中心的距离决定延迟
        const dist = Math.sqrt((col - centerCol) ** 2 + (row - centerRow) ** 2);
        const delay = Math.round(dist * 4);
        const progress = spring({ frame, fps, delay, config: SPRING.pop });

        return (
          <div key={i} style={{
            width: cellSize, height: cellSize,
            opacity: progress,
            transform: `scale(${progress})`,
          }}>
            {item}
          </div>
        );
      })}
    </div>
  );
};

3. 链 / 序列模式

弹簧链（顺序动画）

模仿React Spring的useChain——使用measureSpring计时按顺序触发动画。

import { spring, measureSpring, interpolate, useCurrentFrame, useVideoConfig } from 'remotion';

const SpringChain: React.FC = () => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  // 步骤1: 容器缩放入场
  const step1Config = SPRING.bouncy;
  const step1 = spring({ frame, fps, config: step1Config });
  const step1Duration = measureSpring({ fps, config: step1Config });

  // 步骤2: 标题淡入上升（在步骤1完成80%时开始）
  const step2Delay = Math.round(step1Duration * 0.8);
  const step2Config = SPRING.snappy;
  const step2 = spring({ frame, fps, delay: step2Delay, config: step2Config });
  const step2Duration = measureSpring({ fps, config: step2Config });

  // 步骤3: 副标题出现（在步骤2完成时开始）
  const step3Delay = step2Delay + step2Duration;
  const step3 = spring({ frame, fps, delay: step3Delay, config: SPRING.gentle });

  return (
    <AbsoluteFill style={{ display: 'flex', alignItems: 'center', justifyContent: 'center' }}>
      {/* 容器 */}
      <div style={{
        transform: `scale(${step1})`,
        opacity: step1,
        background: '#1e293b',
        padding: 60,
        borderRadius: 24,
        textAlign: 'center',
      }}>
        {/* 标题 */}
        <h1 style={{
          fontSize: 72, fontWeight: 'bold', color: '#fff',
          opacity: step2,
          transform: `translateY(${interpolate(step2, [0, 1], [30, 0])}px)`,
        }}>弹簧链</h1>
        {/* 副标题 */}
        <p style={{
          fontSize: 28, color: 'rgba(255,255,255,0.7)', marginTop: 16,
          opacity: step3,
          transform: `translateY(${interpolate(step3, [0, 1], [20, 0])}px)`,
        }}>顺序弹簧编排</p>
      </div>
    </AbsoluteFill>
  );
};

useSpringChain 钩子

可重用钩子用于链接多个弹簧带重叠控制。

import { spring, measureSpring, SpringConfig, useCurrentFrame, useVideoConfig } from 'remotion';

type ChainStep = {
  config: Partial<SpringConfig>;
  overlap?: number; // 0-1, 与前一步骤重叠多少（默认0）
};

function useSpringChain(steps: ChainStep[]) {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  let currentDelay = 0;
  return steps.map((step, i) => {
    if (i > 0) {
      const prevDuration = measureSpring({ fps, config: steps[i - 1].config });
      const overlap = step.overlap ?? 0;
      currentDelay += Math.round(prevDuration * (1 - overlap));
    }
    return spring({ frame, fps, delay: currentDelay, config: step.config });
  });
}

// 用法:
const [container, title, subtitle, cta] = useSpringChain([
  { config: SPRING.bouncy },
  { config: SPRING.snappy, overlap: 0.2 },
  { config: SPRING.gentle, overlap: 0.3 },
  { config: SPRING.pop, overlap: 0.1 },
]);

4. 多属性弹簧

每个属性不同物理

const MultiPropertySpring: React.FC<{ delay?: number }> = ({ delay = 0 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  // 位置: 快照（快速到达）
  const position = spring({ frame, fps, delay, config: SPRING.snappy });
  // 缩放: 弹跳（过冲然后稳定）
  const scale = spring({ frame, fps, delay, config: SPRING.bouncy });
  // 旋转: 摇摆（弹性摆动）
  const rotation = spring({ frame, fps, delay, config: SPRING.wobbly });
  // 不透明度: 平滑（无弹跳）
  const opacity = spring({ frame, fps, delay, config: SPRING.smooth });

  const translateX = interpolate(position, [0, 1], [-300, 0]);
  const rotate = interpolate(rotation, [0, 1], [-15, 0]);

  return (
    <div style={{
      transform: `translateX(${translateX}px) scale(${scale}) rotate(${rotate}deg)`,
      opacity,
    }}>
      多属性
    </div>
  );
};

5. 弹簧计数器

带弹簧物理的数字计数器——过冲目标然后稳定。

const SpringCounter: React.FC<{
  endValue: number;
  prefix?: string;
  suffix?: string;
  preset?: keyof typeof SPRING;
  delay?: number;
}> = ({ endValue, prefix = '', suffix = '', preset = 'bouncy', delay = 0 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const progress = spring({ frame, fps, delay, config: SPRING[preset] });
  // 带弹跳配置，进度在稳定前过冲超过1.0
  // 这意味着计数器短暂显示数字 > endValue，然后稳定
  const value = Math.round(progress * endValue);

  return (
    <div style={{
      fontSize: 96, fontWeight: 'bold', color: '#fff',
      fontVariantNumeric: 'tabular-nums',
    }}>
      {prefix}{value.toLocaleString()}{suffix}
    </div>
  );
};

与线性计数器比较:

  • interpolate() 计数器: 平滑达到精确目标，无过冲
  • 弹簧计数器: 过冲然后稳定——感觉更有能量和活力

6. 3D变换模式

弹簧卡片翻转

const SpringCardFlip: React.FC<{
  frontContent: React.ReactNode;
  backContent: React.ReactNode;
  flipDelay?: number;
}> = ({ frontContent, backContent, flipDelay = 15 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const flipProgress = spring({
    frame, fps, delay: flipDelay,
    config: { damping: 15, stiffness: 80 }, // 慢，重量翻转
  });
  const rotateY = interpolate(flipProgress, [0, 1], [0, 180]);

  return (
    <AbsoluteFill style={{ display: 'flex', alignItems: 'center', justifyContent: 'center' }}>
      <div style={{ perspective: 800 }}>
        <div style={{
          width: 500, height: 320, position: 'relative',
          transformStyle: 'preserve-3d',
          transform: `rotateY(${rotateY}deg)`,
        }}>
          <div style={{
            position: 'absolute', inset: 0, backfaceVisibility: 'hidden',
            background: '#1e293b', borderRadius: 16,
            display: 'flex', alignItems: 'center', justifyContent: 'center', padding: 32,
          }}>{frontContent}</div>
          <div style={{
            position: 'absolute', inset: 0, backfaceVisibility: 'hidden',
            background: '#3b82f6', borderRadius: 16, transform: 'rotateY(180deg)',
            display: 'flex', alignItems: 'center', justifyContent: 'center', padding: 32,
          }}>{backContent}</div>
        </div>
      </div>
    </AbsoluteFill>
  );
};

透视倾斜

const PerspectiveTilt: React.FC<{
  children: React.ReactNode;
  rotateX?: number;
  rotateY?: number;
  delay?: number;
}> = ({ children, rotateX = -20, rotateY = 15, delay = 0 }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const progress = spring({ frame, fps, delay, config: SPRING.heavy });
  const rx = interpolate(progress, [0, 1], [rotateX, 0]);
  const ry = interpolate(progress, [0, 1], [rotateY, 0]);
  const translateZ = interpolate(progress, [0, 1], [-200, 0]);

  return (
    <div style={{
      perspective: 1000,
      display: 'flex', alignItems: 'center', justifyContent: 'center',
    }}>
      <div style={{
        transform: `perspective(1000px) rotateX(${rx}deg) rotateY(${ry}deg) translateZ(${translateZ}px)`,
        opacity: progress,
      }}>
        {children}
      </div>
    </div>
  );
};

7. 弹簧过渡

带弹簧的交叉淡化

const SpringCrossfade: React.FC<{
  outgoing: React.ReactNode;
  incoming: React.ReactNode;
  switchFrame: number;
}> = ({ outgoing, incoming, switchFrame }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const outOpacity = frame < switchFrame ? 1 : 1 - spring({
    frame: frame - switchFrame, fps, config: SPRING.smooth,
  });
  const inOpacity = frame < switchFrame ? 0 : spring({
    frame: frame - switchFrame, fps, config: SPRING.smooth,
  });
  const inScale = frame < switchFrame ? 0.95 : interpolate(
    spring({ frame: frame - switchFrame, fps, config: SPRING.bouncy }),
    [0, 1], [0.95, 1]
  );

  return (
    <AbsoluteFill>
      <AbsoluteFill style={{ opacity: outOpacity }}>{outgoing}</AbsoluteFill>
      <AbsoluteFill style={{ opacity: inOpacity, transform: `scale(${inScale})` }}>
        {incoming}
      </AbsoluteFill>
    </AbsoluteFill>
  );
};

带弹簧的滑动过渡

const SpringSlide: React.FC<{
  outgoing: React.ReactNode;
  incoming: React.ReactNode;
  switchFrame: number;
  direction?: 'left' | 'right' | 'up' | 'down';
}> = ({ outgoing, incoming, switchFrame, direction = 'left' }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const progress = frame < switchFrame ? 0 : spring({
    frame: frame - switchFrame, fps, config: SPRING.snappy,
  });

  const getTransform = (isOutgoing: boolean) => {
    const offset = isOutgoing ? interpolate(progress, [0, 1], [0, -100]) : interpolate(progress, [0, 1], [100, 0]);
    switch (direction) {
      case 'left': return `translateX(${offset}%)`;
      case 'right': return `translateX(${-offset}%)`;
      case 'up': return `translateY(${offset}%)`;
      case 'down': return `translateY(${-offset}%)`;
    }
  };

  return (
    <AbsoluteFill style={{ overflow: 'hidden' }}>
      <AbsoluteFill style={{ transform: getTransform(true) }}>{outgoing}</AbsoluteFill>
      <AbsoluteFill style={{ transform: getTransform(false) }}>{incoming}</AbsoluteFill>
    </AbsoluteFill>
  );
};

8. 模板

弹簧标题卡

const SpringTitleCard: React.FC<{
  title: string;
  subtitle?: string;
  accent?: string;
}> = ({ title, subtitle, accent = '#3b82f6' }) => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  // 背景形状
  const bgScale = spring({ frame, fps, config: SPRING.heavy });
  // 标题单词错开
  const words = title.split(' ');
  // 分隔线
  const dividerWidth = spring({ frame, fps, delay: 8, config: SPRING.snappy });
  // 副标题
  const subtitleProgress = spring({ frame, fps, delay: 15, config: SPRING.gentle });

  return (
    <AbsoluteFill style={{
      background: '#0f172a',
      display: 'flex', alignItems: 'center', justifyContent: 'center',
    }}>
      {/* 强调圆圈 */}
      <div style={{
        position: 'absolute', width: 300, height: 300, borderRadius: '50%',

9. 实用工具: useSpringTrail

用于轨迹动画的可重用钩子。

import { spring, SpringConfig, useCurrentFrame, useVideoConfig } from 'remotion';

function useSpringTrail(
  count: number,
  config: Partial<SpringConfig>,
  staggerFrames = 4,
  baseDelay = 0,
) {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  return Array.from({ length: count }, (_, i) => {
    const delay = baseDelay + i * staggerFrames;
    return spring({ frame, fps, delay, config });
  });
}

// 用法:
const trail = useSpringTrail(5, SPRING.pop, 4);
// trail = [0.98, 0.85, 0.5, 0.1, 0] -- 每个项目在不同进度

10. 实用工具: useSpringEnterExit

用于入场 + 退场模式的可重用钩子。

function useSpringEnterExit(
  enterConfig: Partial<SpringConfig>,
  exitConfig: Partial<SpringConfig>,
  enterDelay = 0,
  exitBeforeEnd = 30,
) {
  const frame = useCurrentFrame();
  const { fps, durationInFrames } = useVideoConfig();

  const enter = spring({ frame, fps, delay: enterDelay, config: enterConfig });
  const exit = spring({
    frame, fps,
    delay: durationInFrames - exitBeforeEnd,
    config: exitConfig,
  });

  return enter - exit;
}

// 用法:
const progress = useSpringEnterExit(SPRING.bouncy, SPRING.stiff, 0, 25);

11. 与其他技能结合

const CombinedScene: React.FC = () => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const bgOpacity = spring({ frame, fps, config: SPRING.smooth });

  return (
    <AbsoluteFill>
      {/* react-animation: 视觉氛围 */}
      <div style={{ opacity: bgOpacity }}>
        <Aurora colorStops={['#3A29FF', '#FF94B4']} />
      </div>

      {/* spring-animation: 弹跳标题入场 */}
      <SpringTitleCard title="自然运动" subtitle="物理驱动的美" />

      {/* gsap-animation: 文本拆分，弹簧无法实现 */}
      <GSAPTextReveal text="高级排版" />
    </AbsoluteFill>
  );
};
技能 最佳用途
弹簧动画 弹跳入场、弹性轨迹、有机物理、过冲效果、弹簧计数器
gsap-animation 文本拆分（SplitText）、SVG绘制（DrawSVG）、SVG变形、复杂时间线标签
react-animation 视觉背景（Aurora, Silk, Particles）、着色器效果
