CristianOlivera1/openvid — reverse-engineered prompt

Build me a browser based app for making polished product demo videos and mockups quickly.

I want people to be able to record their screen or upload a video, then edit it in the browser with nice backgrounds, device frames like browsers or phones, zoom moments on the timeline, rounded corners, shadows, padding, rotation, and simple 3D style movement. They should also be able to add text, shapes, SVGs, images, and layer them above or below the video.

Please include audio controls with multiple tracks, volume settings, and an option to keep or remove the original video sound. Add export options for common video qualities like 4K, 1080p, and 720p, plus formats like MP4, WebM, GIF, and images.

Use a modern web app setup with TypeScript and Next.js. Add login with Google, GitHub, and Twitch through Supabase. Keep everything clean, fast, and usable directly in the browser with no desktop install. Look up current docs online if you need to.
