Overview

Clypra is a free, open-source video editor (MIT License) with professional-grade features. Everything is 100% free and open source—no watermarks, no paywalls, no feature limits, and no subscriptions required.

Supported Platforms

• Desktop: macOS (Apple Silicon & Intel), Windows 10/11, Linux
• Mobile: iOS & Android (via Capacitor)

Key Features

• 🎬 Multi-Track Timeline & Editing — Frame-accurate trimming, multi-layer track arrangement, and complete undo/redo history.
• ⚡ Hardware-Accelerated Engine — Sub-10ms decoding latency powered by native Rust, GPU decoding (VideoToolbox, D3D11VA, VAAPI), and FFmpeg.
• 🎵 High-Fidelity Audio & Waveforms — Real-time peak + RMS waveform rendering, frame-accurate AV sync, and clip volume controls.
• 🎨 Text & Visual Compositing — Custom text styling, animated overlays, filters, and real-time canvas previews.
• 📦 Multi-Format Import & Export — Support for MP4, MOV, WebM, MKV, MP3, WAV, PNG, and high-quality ProRes/H.264 export.
• 🛡️ Zero-Overhead Performance Telemetry — Production-only frame timing analysis to optimize driver compatibility and cross-OS rendering with zero PII.

⚡ Production Performance Telemetry & Privacy

To ensure stutter-free 60 FPS playback and diagnose edge-case GPU driver regressions across diverse hardware configurations, Clypra includes a lightweight, non-blocking telemetry collector:

• What We Collect: High-level numerical timings (decode $\mu$s, compose $\mu$s, P95 seek latency, dropped frame counts, OS family, and GPU vendor/model).
• Strict Privacy (Zero PII): Zero video frames, media assets, project titles, file paths, or personal user identities are ever accessed or sent.
• Adaptive Sampling: Smooth 60 FPS playback is sampled at 1%, while dropped frames ($>5%$) and driver fallbacks are captured at 100% to isolate regressions without impacting playback frame pacing.
• Analysis Hub: Aggregated performance metrics are analyzed by engineers in the Clypra Studio Admin Console (/studio/admin).

For technical details, see the Performance Telemetry Specification.

Architecture

Clypra is built with a native Rust/Tauri v2 core for hardware video operations, coupled with a React 19 frontend.
