Screen Studio
Professional screen recorder for macOS
Desktop Video Tool
The verdict
Keep paying for Screen Studio; building a native macOS video editor with custom capture pipelines and hardware acceleration requires serious systems programming that AI coding agents cannot reliably complete.
Screen Studio is a deeply native macOS app built using low-level AVFoundation, ScreenCaptureKit, and hardware-accelerated rendering. While an AI agent can help you scaffold an Electron or web-based video trimmer prototype, replicating the buttery-smooth 60fps native performance, real-time audio taps, device USB mirroring, and VideoToolbox exports requires extensive native Swift debugging and systems engineering expertise that breaks down during complex multi-threaded rendering loops.
Estimated effort: 6+ months of full-time work
What you can't replicate
- Butter-smooth 60fps native macOS screen capture and hardware encoding
- Low-level system audio routing and capture without third-party kernel extensions
- Flawless native gesture and frame performance on Apple Silicon

Build guide
01Project Scaffolding & macOS Native Shell
Initialize a native Swift macOS application using SwiftUI and AppKit with proper entitlement configurations for screen recording.
Create a new Swift package and macOS application project template targeting macOS Ventura 13.1+ using SwiftUI. Configure the project structure with modular targets for CaptureEngine, TimelineEditor, and Exporter. Add necessary Info.plist privacy permissions for screen recording, camera access, and microphone access. Write a robust build script using Swift Package Manager to verify compilation without errors.02ScreenCaptureKit Recording Engine
Implement low-level screen capture and audio recording using Apple's ScreenCaptureKit and AVFoundation frameworks.
Implement a native Swift recording engine utilizing ScreenCaptureKit to capture full screens, individual application windows, or selected regions at 60fps. Integrate AVFoundation to simultaneously capture microphone audio and system audio taps. Handle stream errors, permissions prompts, start/pause/resume state transitions, and temporary raw file output storage safely on disk.03Cursor Tracking and Spring-Physics Smoothing
Capture mouse events and construct interpolation matrices for smooth cursor gliding, resizing, and hiding.
Build a mouse event logging and processing module in Swift that records cursor coordinates, click events, and timestamp arrays during capture sessions. Implement spring-physics math functions to transform erratic cursor movements into smooth gliding trajectories during playback preview. Add dynamic scaling logic to resize high-resolution cursor assets and automatically hide static cursors after inactivity.04Timeline and Zoom Keyframing Editor
Develop a multi-slice timeline interface with automatic and manual pan-and-zoom keyframe controls.
Create a responsive SwiftUI timeline component supporting multi-slice cutting, trimming, and playback speed adjustments. Implement zoom tracking logic that automatically calculates bounding boxes around active UI regions or allows manual keyframe placement. Ensure timeline scrubbing updates the video preview frame smoothly at 60fps without dropping memory buffers.05Aesthetic Framing, Backgrounds, and Device Mockups
Add customizable device frames, wallpapers, shadows, and rounded corners around video canvases.
Build a rendering composition layer that wraps recorded video feeds inside configurable device mockups (iPhone, iPad) with proper device model detection, color variants, and rounded corner masks. Implement background wallpaper gradient selectors, drop shadow filters, outer spacing padding adjustments, and inset controls.06Hardware-Accelerated Video Composition and Export
Export final multi-track compositions using VideoToolbox encoders up to 4K 60fps.
Implement a high-performance export pipeline using AVAssetWriter and Apple's VideoToolbox hardware-accelerated video encoders. Support exports up to 4K resolution at 60fps, animated GIF generation, and multi-project queue processing. Include progress reporting indicators, error recovery handlers for resource path limits, and disk space verification checks before encoding starts.
