CalcFocus - Open-source screen recorder for polished product demos

Hey Product Hunt! I’m excited to share CalcFocus, an open-source screen recorder, screenshot tool, and editor for people who make product demos, tutorials, walkthroughs, and launch videos. I built CalcFocus because recording a screen is easy, but making the result look polished usually takes too much extra editing. The goal is to make that workflow feel much lighter: record your screen, let CalcFocus suggest zooms based on cursor movement, refine the details, style the frame, and export a clean MP4 or GIF. What CalcFocus can do today: - Record a screen, window, or selected area - Auto-suggest zooms from cursor activity - Smooth cursor movement and add click animations - Trim, add speed regions, annotations, and zoom spans - Style videos with backgrounds, padding, rounded corners, and shadows - Capture and edit screenshots - Export to MP4 or GIF - Save and reopen `.calcfocus` projects It’s built with Tauri, Rust, React, and PixiJS, and it’s AGPL-licensed. I’d love feedback from makers, designers, developers, and creator-tools people: What would make this more useful for your own product demo workflow?
