Quick Start
Requires inference.sh CLI (belt). Install instructions
belt loginRender 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; }",

}'
## Input Schema
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|

## Available Imports
Your TSX code can import from `remotion` and `react`:
// Remotion APIs
import {
useCurrentFrame,
useVideoConfig,
spring,

Audio,
Video,
Img
} from "remotion";
// React
import React, { useState, useEffect } from "react";

}'
## Python SDK
from inferencesh import inference
client = inference()
result = client.run({
"app": "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 }}>

</h1>
</AbsoluteFill>
);
}
""",

### Streaming Progress
for update in client.run({
"app": "infsh/remotion-render",
"input": {
"code": "...",
"duration_seconds": 10
}
}, stream=True):
if update.get("progress"):

if update.get("output"):
print(f"Video: {update['output']['video']}")
