安装 belt CLI 技能： npx skills add belt-sh/cli

Remotion 渲染

通过 inference.sh CLI，根据 React/Remotion 组件代码渲染视频。

快速开始

需要 inference.sh CLI（belt）。安装说明

# Render a simple animation
belt app run infsh/remotion-render --input '{
  "code": "import { useCurrentFrame, AbsoluteFill } from \"remotion\"; export default function Main() { const frame = useCurrentFrame(); return <AbsoluteFill style={{backgroundColor: \"#000\", display: \"flex\", justifyContent: \"center\", alignItems: \"center\"}}><h1 style={{color: \"white\", fontSize: 100, opacity: frame / 30}}>Hello World</h1></AbsoluteFill>; }",
  "duration_seconds": 3,
  "fps": 30,
  "width": 1920,
  "height": 1080
}'

输入架构

参数	类型	必填	描述
code	string	是	React 组件 TSX 代码。必须默认导出一个组件。
composition_id	string	否	要渲染的合成 ID
props	object	否	传递给组件的 Props
width	number	否	视频宽度（像素）
height	number	否	视频高度（像素）
fps	number	否	每秒帧数
duration_seconds	number	否	视频时长（秒）
codec	string	否	输出编解码器

可用导入项

你的 TSX 代码可以从 remotion 和 react 导入：

// Remotion APIs
import {
  useCurrentFrame,
  useVideoConfig,
  spring,
  interpolate,
  AbsoluteFill,
  Sequence,
  Audio,
  Video,
  Img
} from "remotion";

// React
import React, { useState, useEffect } from "react";

示例

淡入文本

belt app run infsh/remotion-render --input '{
  "code": "import { useCurrentFrame, AbsoluteFill, interpolate } from \"remotion\"; export default function Main() { const frame = useCurrentFrame(); const opacity = interpolate(frame, [0, 30], [0, 1]); return <AbsoluteFill style={{backgroundColor: \"#1a1a2e\", display: \"flex\", justifyContent: \"center\", alignItems: \"center\"}}><h1 style={{color: \"#eee\", fontSize: 80, opacity}}>Welcome</h1></AbsoluteFill>; }",
  "duration_seconds": 2,

  "props": {"title": "My Video", "subtitle": "Created with Remotion"},
  "duration_seconds": 3,
  "fps": 30,
  "width": 1920,
  "height": 1080
}'

belt app run infsh/remotion-render --input '{
  "code": "import { useCurrentFrame, AbsoluteFill, Sequence, interpolate } from \"remotion\"; function FadeIn({ children }) { const frame = useCurrentFrame(); const opacity = interpolate(frame, [0, 20], [0, 1]); return <div style={{ opacity }}>{children}</div>; } export default function Main() { return <AbsoluteFill style={{backgroundColor: \"#000\", display: \"flex\", justifyContent: \"center\", alignItems: \"center\", flexDirection: \"column\", gap: 20}}><Sequence from={0}><FadeIn><h1 style={{color: \"#fff\", fontSize: 60}}>First</h1></FadeIn></Sequence><Sequence from={30}><FadeIn><h1 style={{color: \"#fff\", fontSize: 60}}>Second</h1></FadeIn></Sequence><Sequence from={60}><FadeIn><h1 style={{color: \"#fff\", fontSize: 60}}>Third</h1></FadeIn></Sequence></AbsoluteFill>; }",
  "duration_seconds": 4,
  "fps": 30,
  "width": 1920,
  "height": 1080
}'
