Serene Video is a powerful, browser-based media player designed as a modern alternative to traditional desktop applications like VLC. It runs entirely on your local machine, ensuring your files and viewing habits remain completely private. No installation is required—simply open the web app and play your videos with advanced features that rival desktop software. By harnessing the capabilities of modern web browsers, Serene Video delivers an elegant and feature-rich experience without the overhead of a native application. It is built as a Progressive Web App (PWA), which means you can optionally "install" it to your desktop for an app-like experience and even set it as your default player for video files (.mp4, .mkv, .webm, .mov). Its clean, minimalist interface is designed for a serene, distraction-free viewing experience, while still providing robust tools for power users, especially those who work heavily with subtitles. Key Features: 100% Private & Secure: All processing is done directly in your browser. Your files never leave your computer, and nothing is ever uploaded to a server. Advanced Subtitle Control: Serene Video excels at subtitle management. Easily load external .srt or .vtt files. Its standout feature is the ability to import a .zip archive containing multiple subtitle tracks (perfect for subtitles extracted from MKV files) and allows you to select, preview, and even download individual tracks from within the player. Powerful Looping Tools: Go beyond simple repeats with a precision A-B Segment Loop tool, which is ideal for detailed analysis, learning, or practice. Standard full-video looping is also available. Full Playlist Management: Create and manage a playlist of your local video files with automatically generated thumbnails, easy reordering (drag-and-drop is implied by the up/down buttons), and seamless navigation between files. Modern Viewing Experience: Enjoy a clean interface with Picture-in-Picture (PiP), a Fill/Zoom mode to handle different video aspect ratios, and full integration with your operating system's native media controls (e.g., play/pause from your keyboard). Zero Installation, Full Integration: Use it instantly in your browser on any OS (Windows, macOS, Linux, ChromeOS) or install it as a PWA to combine the accessibility of the web with the power of the desktop.
