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; }", "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 |
| `fps` | number | No | Frames per second |
| `duration_seconds` | number | No | Video duration in seconds |
| `codec` | string | No | Output codec |

## 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";
