無損影片/音訊編輯的瑞士軍刀
mifi/lossless-cut 是一款功能強大的無損影片與音訊編輯工具，專為需要快速、精確切割或合併媒體檔案而不損失原始編碼品質的使用者設計。它支援多種常見格式，如 MP4、MKV、MOV、MP3 等，並提供直觀的波形圖與時間軸預覽，讓開發者與影音創作者能輕鬆進行片段擷取、修剪、合併，甚至批次處理。此工具基於 FFmpeg 與 Chromium 技術，可在 Windows、macOS 與 Linux 平台上運作，並以命令列或圖形介面方式靈活操作。其獨特的「無損」特性意味著編輯過程不重新編碼，保留了原始影片的畫質與音質，特別適合用於移除廣告、擷取精彩片段或整理大型媒體檔案。
