Edit video with hardware acceleration without subscription fees
If you have experienced interrupted work due to dropped frames or slow rendering during video editing, this tool may be the answer. Clypra is a free open-source video editor that uses hardware acceleration to reduce frame decoding time to under 10ms and enables smooth playback through GPU-native rendering. You can use all professional editing features without watermarks or subscription fees.
Hardware acceleration engine and frame-precise editing
Clypra is built on Rust, Tauri v2, and React 19, featuring a hardware acceleration engine. It utilizes GPU decoding technologies such as VideoToolbox, D3D11VA, and VAAPI to keep frame decoding latency under 10ms. The timeline allows for precise editing at the frame level, and you can freely arrange tracks across multiple layers. All editing operations support full undo and redo functionality, allowing you to correct mistakes immediately.
Audio, text, and various format support
You can visually inspect audio through real-time peak and RMS waveform rendering and synchronize audio and video at the frame level. Per-clip volume adjustment is also possible. The tool provides visual compositing features such as text styling, animated overlays, and filter application, with real-time preview on the canvas. It imports files in various formats including MP4, MOV, WebM, MKV, MP3, WAV, and PNG, and allows high-quality export to ProRes and H.264.
Performance telemetry and privacy
Clypra includes a lightweight telemetry collector to ensure the stability of 60FPS playback and diagnose GPU driver issues. It collects only numerical data such as decoding time, compositing time, P95 seek latency, dropped frame count, OS family, and GPU vendor and model. It never collects personal information such as video frames, media assets, project titles, file paths, or user identity. It samples 1% of data when playback is smooth, and collects 100% when dropped frames exceed 5% or a driver fallback occurs, to isolate issues.
Installation and development environment
It supports macOS, Windows 10/11, Linux desktop, and iOS and Android mobile (via Capacitor). On macOS, you can install it using the Homebrew command brew install AIEraDev/tap/clypra or the Clypra-universal.dmg file. For Windows, download and run Clypra-x64.msi; for Linux, download and run Clypra-x86_64.AppImage. To clone the repository for development, you need Node.js 18+, Rust 1.70+, and FFmpeg 6.0+. Install dependencies with npm install, copy .env.example to .env, and run development mode with npm run tauri dev.
License and contribution
Clypra is released under the MIT license, while its FFmpeg dependency follows the LGPL v2.1+ license. All features are 100% free and open source, with no watermarks, paywalls, feature restrictions, or subscriptions.
