Transform raw screen recordings into stunning cinematic product walkthroughs entirely in your browser.

Hey dev community! 👋

Every time we build a cool SaaS, an open-source tool, or a new feature, we face the same bottleneck: Creating a high-quality product demo video.

Traditional tools like Adobe After Effects or Premiere require heavy installations, complex timelines, and hours of rendering. To solve this, I’ve been diving into Openvid—a powerful, browser-based cinematic video studio designed specifically for software developers and creators.

👉 Try it live: openvid.dev
⭐ Check out the source code: GitHub - CristianOlivera1/openvid

Here is a quick look at why it’s a game-changer for engineering and product rollouts.

🔥 Key Features That Make Openvid Unique

Openvid converts flat, boring screen captures into studio-grade promotional material using just a few clicks:

Cinematic 3D Camera Movements: Add smooth easing zooms, pans, and 3D tilts directly on top of your timeline to highlight specific lines of code or UI interactions.
Modern Device Mockups: Instantly wrap your recordings into clean browser frames (Arc, Safari, Chrome) or mobile layouts with adjustable shadows and rounded corners.
100% Client-Side Processing: No servers involved. Your heavy video files never leave your machine, keeping your unreleased source code safe and private.
Pro Export Suite: Supports rendering up to 4K at 30fps in standard MP4 (H.264), WebM with alpha transparency channels, or lightweight GIFs.

🛠️ Under the Hood: The Architecture

The architecture of Openvid showcases how powerful the modern web platform has become. It brings desktop-level rendering straight to a browser tab using:

Framework: Next.js and TypeScript for structural speed and component modularity.
Video Rendering Engine: FFmpeg.wasm (WebAssembly) to execute native FFmpeg processing directly inside your browser cache.
3D Visuals: Three.js and Canvas APIs managing the dynamic perspectives, camera dampening, and studio lightning effects.
Local Storage: IndexedDB to handle massive video fragments seamlessly without crashing the browser memory.

💬 What Do You Think?

I really think browser-based tools powered by WebAssembly are going to completely replace basic desktop video editors for technical documentation and marketing.

Do you still rely on traditional video tools for your launch demos?
What feature would make Openvid an immediate replacement in your workflow?
