OpenVid is a browser-based tool that lets you record your screen or upload video, apply cinematic enhancements, and export polished demos and mockups without leaving your browser. Built for speed, flexibility, and collaboration, OpenVid brings together video input, mockup creation, 3D effects, and a rich set of visual options into a single, accessible workflow. The project is designed to run fully in-browser, leveraging modern web technologies to render, edit, and export high-quality demos with minimal friction. This article dives into what makes OpenVid unique, how its features come together, and how you can get started today.

A Quick Overview: Why OpenVid Stands Out

• Record and edit in-browser: No desktop client installation required. Capture your screen or upload footage, then enhance with dynamic zooms, device frames, and 3D movements.
• Versatile inputs: Accept screen recordings, MP4, WebM, QuickTime, and MKV uploads. Drag-and-drop simplicity keeps your workflow smooth.
• Rich visual toolbox: Apply mockups, 3D transformations, image masking, backgrounds, effects, and precise camera movements to create cinematic demos.
• Comprehensive export options: Choose from multiple resolutions and formats (including 4K, MP4, WebM, GIF, and image series) to suit your distribution needs.
• Strong authentication and data handling: Supabase Auth powers secure login with OAuth across major providers, alongside local storage options for convenience.
• Tight integration with modern tech: The project stacks Next.js, TypeScript, Supabase, and a modern UI/UX kit to deliver fast performance and accessible components.

Visuals to set the mood

To give you a sense of the product in action, imagine a cinematic demo where a presenter’s screen recording slides smoothly into a device frame, then transitions into multi-layer overlays, dynamic shadows, and a subtle camera tilt that follows the action. The demo above was fully recorded and edited inside OpenVid, illustrating the pipeline from input to a share-ready export. The interface balances control and clarity, guiding you through each step without overwhelming you with options.

Core Features: A Deep Dive

OpenVid in Action: A Visual Tour

To appreciate the scope of OpenVid, take a visual tour of what’s possible within a single project. The multi-layer capabilities let you take a basic screen recording and turn it into a cinematic product demo with device frames, dynamic camera work, and contextual visuals. The result is a share-ready video that communicates value quickly and professionally.

In addition to the primary hero imagery, a sample frame demonstrates the transition from raw footage to a refined, polished output. The frame image below illustrates how a shot can be integrated with device mockups and background layers to convey context and polish.
