Add a runtime adapter that bridges Remotion compositions into HyperFrames'
deterministic capture pipeline. Remotion React components render inside
HyperFrames HTML compositions via a simple registration contract:
window.__hfRemotion.push({ seekTo, pause, durationInFrames, fps })
The adapter converts HyperFrames' time-based seeks to Remotion's frame-based
seeks, enabling both GSAP and React to render in the same frame.
What's included:
- Runtime adapter (packages/core/src/runtime/adapters/remotion.ts)
- Adapter package (packages/adapter-remotion/) with mount helper + primitives
- Interop guide (docs/guides/remotion-interop.md)
- Working example (examples/remotion-adapter/)
Bug fixes discovered during development:
- fix(cli): use function replacement in validate to avoid $& expansion
- fix(producer): same $& bug in CDN script inlining
- fix(producer): externalize postcss in esbuild config

@hyperframes/producer
Full HTML-to-video rendering pipeline: capture frames with Chrome's BeginFrame API, encode with FFmpeg, mix audio — all in one call.
Install
npm install @hyperframes/producer
Requirements: Node.js >= 22, Chrome/Chromium (auto-downloaded), FFmpeg
Usage
Render a video
import { createRenderJob, executeRenderJob } from "@hyperframes/producer";
const job = createRenderJob({
inputPath: "./my-composition.html",
outputPath: "./output.mp4",
width: 1920,
height: 1080,
fps: 30,
});
const result = await executeRenderJob(job, (progress) => {
console.log(`${Math.round(progress.percent * 100)}%`);
});
console.log(result.outputPath); // ./output.mp4
Run as an HTTP server
The producer can also run as a render server, accepting render requests over HTTP:
import { startServer } from "@hyperframes/producer";
await startServer({ port: 8080 });
// POST /render with a RenderConfig body
Configuration
RenderConfig controls the render pipeline:
| Option | Default | Description |
|---|---|---|
inputPath |
— | Path to the HTML composition |
outputPath |
— | Output video file path |
width |
1920 | Frame width in pixels |
height |
1080 | Frame height in pixels |
fps |
30 | Frames per second (24, 30, or 60) |
quality |
"standard" |
Encoder preset ("draft", "standard", "high") |
How it works
- Serve — spins up a local file server for the HTML composition
- Capture — opens the page in headless Chrome, seeks frame-by-frame via
HeadlessExperimental.beginFrame, captures screenshots - Encode — pipes frames through FFmpeg (with GPU encoder detection and chunked concat)
- Mix — extracts
<audio>elements and mixes them into the final video - Finalize — applies faststart for streaming-friendly MP4
