Remotion Render
Render videos from React/Remotion component code via inference.sh CLI.
Quick Start
Requires inference.sh CLI (
belt). Install instructions
bashbelt login # 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 }'
Input Schema
| Parameter | Type | Required | Description |
|---|---|---|---|
code | string | Yes | React component TSX code. Must export default a component. |
composition_id | string | No | Composition ID to render |
props | object | No | Props passed to the component |
width | number | No | Video width in pixels |
height | number | No | Video height in pixels |

Available Imports
Your TSX code can import from remotion and react:
tsx// Remotion APIs import { useCurrentFrame, useVideoConfig, spring, interpolate, AbsoluteFill, Sequence, Audio, Video, Img } from "remotion"; // React import React, { useState, useEffect } from "react";
