使用以下命令安装:npx skills add remotion-dev/skills
Phase 0: Preflight
阶段0:预检
Before anything else, validate the environment. Run the preflight script:
bash
npx tsx "${SKILL_DIR}/scripts/preflight.ts"This checks:
- Node.js >= 18
- is set
ELEVENLABS_API_KEY - works (cross-platform ffmpeg — no PATH issues)
bunx remotion ffmpeg - Whisper is available for timing verification
If any check fails, show the user the fix instructions from the script output before continuing.
在做任何操作之前,先验证环境。 运行预检脚本:
bash
npx tsx "${SKILL_DIR}/scripts/preflight.ts"这会检查以下项:
- Node.js >= 18
- 已配置
ELEVENLABS_API_KEY - 可正常运行(跨平台ffmpeg,无PATH问题)
bunx remotion ffmpeg - 已安装Whisper用于时序校验
如果任意检查未通过,先向用户展示脚本输出中的修复指引,再继续后续流程。
Phase 1: Understand the Product
阶段1:了解产品
Step 1A: Auto-Discovery
步骤1A:自动信息采集
Before asking the user anything, scan their project for brand context:
bash
npx tsx "${SKILL_DIR}/scripts/discover-brand.ts" "<target-repo-path>"This detects: product name, description, logo files, primary colors, URLs. Use these to pre-populate the interactive prompts below.
在询问用户任何问题之前,先扫描用户项目获取品牌相关信息:
bash
npx tsx "${SKILL_DIR}/scripts/discover-brand.ts" "<target-repo-path>"这会检测:产品名称、描述、Logo文件、主色调、URL。使用这些信息预填充下方的交互式选项。
Step 1B: Input Method
步骤1B:输入方式

"multiSelect": false
}]
}如果选择「分析近期变更」或「两者结合」:
执行深度分析——拉取100条提交记录,读取核心文件:
bash
git log --oneline -100Read models, controllers, services, README
读取模型、控制器、服务、README文件
Then present findings as selectable options for confirmation.
**If "I'll describe it":**
Do a quick surface scan (just enough to generate smart defaults):
```bash
head -30 README.md 2>/dev/null
ls src/ 2>/dev/null | head -10然后将分析结果作为可选项展示给用户确认。
**如果选择「我自行描述」:**
执行快速表层扫描(仅足够生成智能默认值即可):
```bash
head -30 README.md 2>/dev/null
ls src/ 2>/dev/null | head -10Step 1C: Product Brief

}
]
}If user selects "Metallic swoosh": Read metallic-swoosh.md before implementing. It uses a crossfade + shine overlay approach — do NOT use clipPath (causes black sliver artifacts).
Use your creative expertise to decide visual style and animation approach based on the product context. Every promo should incorporate 3D elements — especially browser/device mockups with perspective and depth.

}如果用户选择「金属扫光」: 实现前请先阅读metallic-swoosh.md。它使用交叉淡入+扫光覆盖的方案——不要使用clipPath(会导致黑边伪影)。
根据产品场景使用你的专业创意能力决定视觉风格和动画方案。每个宣传视频都应该融入3D元素——尤其是带有透视和深度的浏览器/设备样机。
Phase 3: Build with Remotion
阶段3:使用Remotion构建
Project Setup
项目初始化
bash
yes "" | npx create-video@latest --blank --no-git <project-name>
cd <project-name>
npm install
npm install lucide-reactbash
yes "" | npx create-video@latest --blank --no-git <project-name>
cd <project-name>
npm install
npm install lucide-reactComposition Setup
合成设置
Set up two compositions in — landscape and portrait from the same scene components:
Root.tsxtsx
import { Composition } from "remotion";
import { MyComposition } from "./Composition";
import { MyCompositionPortrait } from "./CompositionPortrait";
const DURATION = 1800; // Use timing-calculator.ts to compute
export const RemotionRoot: React.FC = () => (
<>
<Composition
id="Promo-Landscape"
component={MyComposition}
durationInFrames={DURATION}
fps={30}
width={1920}
height={1080}
/>
<Composition
id="Promo-Portrait"
component={MyCompositionPortrait}
durationInFrames={DURATION}
fps={30}
width={1080}
height={1920}
/>
</>
);Composition ID rules:
- Use hyphens only, never underscores (e.g., , not
Promo-Landscape)Promo_Landscape - Underscores in composition IDs cause render failures
在中设置两个合成——使用相同的场景组件同时生成横屏和竖屏版本:
Root.tsxtsx
import { Composition } from "remotion";
import { MyComposition } from "./Composition";
import { MyCompositionPortrait } from "./CompositionPortrait";
const DURATION = 1800; // 使用timing-calculator.ts计算
export const RemotionRoot: React.FC = () => (
<>
<Composition
id="Promo-Landscape"
component={MyComposition}
durationInFrames={DURATION}
fps={30}
width={1920}
height={1080}
/>
<Composition
id="Promo-Portrait"
component={MyCompositionPortrait}
durationInFrames={DURATION}
fps={30}
width={1080}
height={1920}
/>
</>
);合成ID规则:
- 仅使用连字符,不要使用下划线(例如,不要用
Promo-Landscape)Promo_Landscape - 合成ID中的下划线会导致渲染失败
Multi-Format Architecture
多格式架构
See multi-format.md for the full LayoutContext pattern. The key idea:
- Create a shared hook that provides
useLayout(){ width, height, isPortrait } - Each scene adapts its layout based on the context
- Landscape compositions wrap scenes in
<LayoutProvider width={1920} height={1080}> - Portrait compositions wrap scenes in
<LayoutProvider width={1080} height={1920}> - Font sizes, padding, and layout direction adjust automatically
This means you write one set of scenes that works in both formats.
查看multi-format.md了解完整的LayoutContext模式。核心思路:
- 创建一个共享的钩子,返回
useLayout(){ width, height, isPortrait } - 每个场景根据上下文适配布局
- 横屏合成使用包裹场景
<LayoutProvider width={1920} height={1080}> - 竖屏合成使用包裹场景
<LayoutProvider width={1080} height={1920}> - 字体大小、内边距和布局方向会自动调整
这意味着你只需要编写一套场景即可适配两种格式。
Scene Duration Guidelines
场景时长指引
- Optimal scene duration: 2-4 seconds (60-120 frames at 30fps)
- Shorter scenes feel more energetic and hold attention
- Only go to 4s for scenes with complex reveals or multiple elements
- Hook scenes can be as short as 1.5s (45 frames)
- 最佳场景时长:2-4秒(30fps下为60-120帧)
- 更短的场景更有活力,更能抓住注意力
- 只有包含复杂展示或多元素的场景才需要4秒
- 钩子场景可以短至1.5秒(45帧)
Duration Calculation
时长计算
TransitionSeries overlaps scenes during transitions. The effective duration is NOT the sum of scene durations.
Formula:
effective = sum(sceneDurations) - (numTransitions × transitionDuration)Run the timing calculator to verify:
bash
npx tsx "${SKILL_DIR}/scripts/timing-calculator.ts" --scenes "120,90,60,90,90,90,120,120,120,120,120,120,120,120,120,120,60" --transition 12 --fps 30Set in Root.tsx to the effective value.
DURATIONTransitionSeries会在转场期间重叠场景。 实际时长不是所有场景时长的总和。
计算公式:
实际时长 = 总场景时长和 - (转场次数 × 转场时长)运行时长计算器进行校验:
bash
npx tsx "${SKILL_DIR}/scripts/timing-calculator.ts" --scenes "120,90,60,90,90,90,120,120,120,120,120,120,120,120,120,120,60" --transition 12 --fps 30将Root.tsx中的设置为计算得到的实际时长。
DURATIONFraming & Sizing
构图与尺寸
- Fill the frame. Elements should be large and confident.
- Headlines: 60-90px minimum. Subtext: 32-44px.
- Browser mockups / device frames: 60-80% of frame width.
- Padding from edges: 60-100px.
- If a scene feels empty, the elements are too small. Scale up.
- 填满画面。元素应该足够大、足够醒目。
- 标题:最小60-90px。辅助文字:32-44px。
- 浏览器样机/设备边框:占画面宽度的60-80%。
- 边缘内边距:60-100px。
- 如果场景看起来很空,说明元素太小了,请放大。
Animation Toolkit
动画工具包
- for natural motion (play with damping, mass, stiffness)
spring() - for precise timing control
interpolate() - CSS 3D transforms (,
perspective,rotateX,rotateY) for depthtranslateZ - Box shadows and gradients for depth
- Lucide icons for consistent iconography
See skill for animation rules. The critical one: ALL animations must use + or . CSS transitions and Tailwind animations are forbidden in Remotion.
remotion-best-practicesuseCurrentFrame()interpolate()spring()- 用于实现自然动效(调整阻尼、质量、刚度参数)
spring() - 用于精确时序控制
interpolate() - CSS 3D变换(、
perspective、rotateX、rotateY)实现深度感translateZ - 阴影和渐变增强深度感
- Lucide图标实现统一的图标风格
查看 Skill了解动画规则。核心要求:所有动画必须使用 + 或实现。 Remotion中禁止使用CSS过渡和Tailwind动画。
remotion-best-practicesuseCurrentFrame()interpolate()spring()Scene Structure
场景结构
Classic structure as a starting point:
- Hook/Opening → Pain Points → Solution Reveal → Features → Results → CTA
But you might do:
- Cold open on a feature → zoom out to problem → solution
- Customer quote → problem → solution → features
- Single continuous zoom through all content
Trust your instincts.
经典结构作为起点:
- 钩子/开场→痛点→解决方案揭晓→功能展示→效果→CTA
但你也可以采用:
- 冷开场展示功能→缩小画面引出问题→解决方案
- 用户评价→问题→解决方案→功能展示
- 单个连续缩放贯穿所有内容
相信你的专业直觉。
After Building
构建完成后
Launch Remotion Studio for preview:
bash
npx remotion studioThen ask:
json
{
"questions": [{
"question": "How does the video look? Ready to add voiceover and music?",
"header": "Preview",
"options": [
{ "label": "Looks good, proceed", "description": "Add voiceover and music" },
{ "label": "Needs changes", "description": "I'll give feedback first" }
],
"multiSelect": false
}]
}启动Remotion Studio进行预览:
bash
npx remotion studio然后询问用户:
json
{
"questions": [{
"question": "视频效果如何?是否可以添加画外音和音乐了?",
"header": "预览",
"options": [
{ "label": "看起来不错,继续", "description": "添加画外音和音乐" },
{ "label": "需要修改", "description": "我先提供反馈" }
],
"multiSelect": false
}]
}Phase 4: Voiceover
阶段4:画外音制作
The voiceover must match the visuals. This is non-negotiable. See voiceover.md for the full generation guide.
画外音必须与画面匹配,这是硬性要求。 查看voiceover.md了解完整的生成指南。
Quick Workflow
快速工作流
- Extract scene timings from your composition — account for TransitionSeries overlaps
- Write script sections — each section references what's on screen at that moment
- Assign emotional presets per section:
| Emotion | Stability | Similarity | Style | Use For |
|---|---|---|---|---|
| Urgent/Rage | 0.15-0.30 | 0.85-0.95 | 0.4-0.5 | Hook frustration, anger |
| Whisper | 0.25-0.35 | 0.90-0.95 | 0.3 | Secret reveal, intimacy |
| Confident | 0.55-0.65 | 0.80-0.90 | 0.2-0.3 | Features, product reveal |
| Warm | 0.60-0.70 | 0.80-0.85 | 0.2 | Social proof, results |
| Neutral | 0.65-0.75 | 0.85 | 0.2 | Standard narration |
| Dramatic | 0.40-0.50 | 0.85-0.90 | 0.3-0.4 | CTA, closing |
- Generate voiceover — use ElevenLabs API with per-section settings:
bash
npx tsx "${SKILL_DIR}/scripts/generate-voiceover.ts" --config voiceover-config.jsonThe config format:
json
{
"voiceId": "pNInz6obpgDQGcFmaJgB",
"model": "eleven_multilingual_v2",
"outputDir": ".",
"sections": [
{
"id": "hook",
"text": "What... what is this?",
"startTime": 1.0,
"emotion": "rage",
"settings": { "stability": 0.20, "similarity_boost": 0.90, "style": 0.4 }
},
{
"id": "reveal",
"text": "What if you never had to guess again?",
"startTime": 8.0,
"emotion": "whisper",
"settings": { "stability": 0.30, "similarity_boost": 0.90, "style": 0.3 }
}
]
}- Verify with Whisper — check actual timestamps match intended:
bash
whisper voiceover.mp3 --model tiny --output_format srtOr with Python:
bash
python -c "
import whisper
model = whisper.load_model('tiny')
result = model.transcribe('voiceover.mp3')
for s in result['segments']:
print(f\"{s['start']:.1f}s - {s['end']:.1f}s: {s['text']}\")
"- Fix ALL overlaps immediately — do not ask the user:
- Shorten text (make it punchier)
- Increase gaps between sections
- Regenerate and verify again
- Repeat until zero overlaps
- 从合成中提取场景时序——考虑TransitionSeries的重叠时长
- 撰写脚本段落——每个段落对应对应时段屏幕上的内容
- 为每个段落分配情感预设:
| 情感 | 稳定性 | 相似度 | 风格 | 适用场景 |
|---|---|---|---|---|
| 紧急/愤怒 | 0.15-0.30 | 0.85-0.95 | 0.4-0.5 | 钩子部分的沮丧、愤怒情绪 |
| 低语 | 0.25-0.35 | 0.90-0.95 | 0.3 | 秘密揭晓、亲密感场景 |
| 自信 | 0.55-0.65 | 0.80-0.90 | 0.2-0.3 | 功能、产品揭晓部分 |
| 温暖 | 0.60-0.70 | 0.80-0.85 | 0.2 | 社会认同、效果展示部分 |

- 生成画外音——使用ElevenLabs API,按段落设置参数:
bash
npx tsx "${SKILL_DIR}/scripts/generate-voiceover.ts" --config voiceover-config.json配置文件格式:
json
{
"voiceId": "pNInz6obpgDQGcFmaJgB",
"model": "eleven_multilingual_v2",
"outputDir": ".",
"sections": [
{
"id": "hook",
"text": "What... what is this?",
"startTime": 1.0,
"emotion": "rage",
"settings": { "stability": 0.20, "similarity_boost": 0.90, "style": 0.4 }
},
{
"id": "reveal",
"text": "What if you never had to guess again?",
"startTime": 8.0,
"emotion": "whisper",
"settings": { "stability": 0.30, "similarity_boost": 0.90, "style": 0.3 }
}
]
}- 使用Whisper校验——检查实际时间戳是否符合预期:
bash
whisper voiceover.mp3 --model tiny --output_format srt或使用Python:
bash
python -c "
import whisper
model = whisper.load_model('tiny')
result = model.transcribe('voiceover.mp3')
for s in result['segments']:
print(f\"{s['start']:.1f}s - {s['end']:.1f}s: {s['text']}\")
"- 立即修复所有重叠问题——无需询问用户:
- 缩短文本(让内容更精炼)
- 增加段落之间的间隔
- 重新生成并再次校验
- 重复直到没有任何重叠
Audio Normalization
音频标准化
After generating voiceover, normalize volume:
bash
bunx remotion ffmpeg -y -i voiceover.mp3 -af "loudnorm=I=-16:TP=-1.5:LRA=11" voiceover-normalized.mp3生成画外音后,对音量进行标准化:
bash
bunx remotion ffmpeg -y -i voiceover.mp3 -af "loudnorm=I=-16:TP=-1.5:LRA=11" voiceover-normalized.mp3Phase 5: Music & Final Render

| Composition ID render error | Use hyphens, not underscores |
| 问题 | 修复方案 |
|---|---|
| 画外音重叠 | 缩短文本或增加间隔,重新生成,用Whisper校验 |
| 画外音与画面不匹配 | 重新阅读场景内容,让脚本与视觉内容匹配 |
| 语速太快 | 添加停顿("..."),降低文本密度 |
| 元素太靠近边缘 | 添加60-100px的内边距 |
| 字体太小 | 放大20-30% |
| 动画生硬 | 调整spring的阻尼/质量参数,添加缓动 |
| 转场太突兀 | 将转场时长增加6帧 |
| 结尾有空白帧 | 延长收尾场景的时长 |
| 开场没有音频 | 生成单独的愤怒/情感音频片段,使用adelay混音 |
| 音乐太大声 | 将音量从0.10降低到0.08 |
| 竖屏布局拥挤 | 增加内边距,缩小字体,垂直堆叠布局 |
| 合成ID渲染错误 | 使用连字符,不要用下划线 |
DON'Ts
禁止项
- No jitter effects — No shaking, vibrating, or jittery motion. Everything should feel smooth and controlled.
- No full scene spinning — Don't rotate the entire scene. 3D rotation should be subtle and purposeful (browser mockup with slight perspective tilt, not a 360 spin).
- No 3D transforms in transitions — Flip, rotate, and other 3D transitions don't render reliably. Stick to 2D: opacity, position, scale, and gradient masks. (3D transforms are fine for in-scene elements.)
- No CSS transitions or Tailwind animations — All motion must use with
useCurrentFrame()orinterpolate(). Remotion renders frame-by-frame; CSS animations don't work.spring() - No underscores in composition IDs — Use hyphens only. Underscores cause render failures.
- No hardcoded ffmpeg paths — Always use for cross-platform compatibility.
bunx remotion ffmpeg - No skipping Whisper verification — Always verify voiceover timing before finalizing.
- 不要添加抖动效果——不要有摇晃、振动或抖动的动效。所有动效都应该平滑可控。
- 不要旋转整个场景——不要整场景旋转。3D旋转应该是微妙且有明确目的的(浏览器样机轻微的透视倾斜,而不是360度旋转)。
- 不要在转场中使用3D变换——翻转、旋转等3D转场渲染稳定性差。坚持使用2D效果:透明度、位置、缩放和渐变遮罩。(场景内的元素可以使用3D变换。)
- 不要使用CSS过渡或Tailwind动画——所有动效必须使用搭配
useCurrentFrame()或interpolate()实现。Remotion是逐帧渲染的,CSS动画无法正常工作。spring() - 合成ID不要使用下划线——仅使用连字符。下划线会导致渲染失败。
- 不要硬编码ffmpeg路径——始终使用保证跨平台兼容性。
bunx remotion ffmpeg - 不要跳过Whisper校验——最终定稿前必须校验画外音时序。
