🚀 Key Features

• Professional Timeline Editor: Trim videos precisely using dynamic timecode scales, a scrubbable playhead, and draggable brackets.
• Frame Stepping & Jumps: Jump to trim boundaries (⏮ / ⏭) and step backward/forward by 100ms (◀ / ▶) for frame-accurate cuts.
• Advanced Encoder Settings: Customize video output formats (.mp4, .webm, .mkv, .mov, etc.), bitrates, target file sizes, locked aspect-ratio resolutions, and framerates.
• Dual-Processing Architecture:
  • Browser Mode (WASM): Processes videos fully client-side inside the browser sandbox using @ffmpeg/ffmpeg (WASM), keeping your data 100% private.
  • Desktop App Mode (Electrobun): Accesses your machine's native, hardware-accelerated FFmpeg for up to 50x faster exports.
