Lightweight desktop GUI to compose and run ffmpeg commands. Pick an input file, choose container and codecs, optionally tweak advanced settings, preview the exact command, copy it, or run it directly in-app.
- Easy input selection: HTML file picker or OS-native dialog.
- Output control: choose output folder and base name.
- Format and codecs: container, video/audio codecs, copy-all streams.
- Advanced options: resolution, bitrate, CRF, preset, framerate, audio gain.
- Live preview: generated ffmpeg command updates on demand.
- One-click actions: copy to clipboard or run via Neutralino subprocess.
- Status feedback: in-app toast with spinner; desktop notifications on start/finish.
- macOS friendly: Cmd+Q quits the app.
- Window state persistence: restores last size and position.
- ffmpeg installed and available on your system PATH.
- macOS (Homebrew):
brew install ffmpeg - Linux (Debian/Ubuntu):

- When running from the app, the working directory is set to the chosen output folder (or the app’s
output/folder). The preview shows the full output path; the runtime command writes to the cwd for simpler paths. - Window size/position are stored under the OS user data directory and restored on startup.
