Screenize is an open-source macOS screen recording application designed to automate the creation of polished videos, serving as an alternative to Screen Studio. It targets users who need professional-looking screen recordings without extensive manual editing, offering features like automatic zoom, cursor effects, and timeline editing. The primary benefit is streamlining the post-production process for screen capture.

How It Works

Screenize employs a two-pass processing model. The initial pass captures raw video alongside mouse and click data. The second pass then applies intelligent zoom, click effects, and background styling through a timeline-based editor, generating polished output without requiring manual keyframing. This approach allows for dynamic visual enhancements derived directly from user interaction data.

Quick Start & Requirements

• Primary install / run command: Download the latest .dmg from GitHub Releases and drag the application to the Applications folder.
• Non-default prerequisites and dependencies: macOS 13.0 or later. Requires granting Screen Recording, Microphone, and Accessibility permissions on first launch. Users may need to bypass macOS Gatekeeper warnings.
• Estimated setup time or resource footprint: Minimal setup time, primarily involving granting permissions and potentially overriding security settings.
• Links: GitHub Releases (implied).

Highlighted Details

• Features screen and window capture via ScreenCaptureKit.
• Smart generation of zoom, click effects, and keystroke keyframes from interaction data.
• Timeline editor for fine-tuning effects with easing curves.
• Configurable click ripple animations and automatic keystroke overlays.
• Support for custom cursors and background styling (solid colors, gradients, images).
• Exports final videos to MP4 or MOV formats.
