Features

Interactive workflow

Medix walks you through conversion via a series of styled prompts:

1. Discovery — scans the path and shows a clean table of files with resolution, duration, and size.
2. Source filter — if multiple input formats exist, pick which ones to convert (multi-select checkbox).
3. Output format — choose from MP4, MKV, WebM, MOV, AVI, or TS.
4. Advanced settings — optionally tune video codec, audio codec, resolution, frame rate, CRF, preset, and audio bitrate.
5. Confirmation — review the conversion plan before anything runs.
6. Progress — per-file and overall progress bars with live ETA.
7. Summary — success/failure counts and error details.

Batch conversion

• Convert a single file, a directory, or a directory tree (-r).
• Output directory defaults to <input>/converted/ or can be set with -o.
• Filename collisions are handled automatically with an incrementing suffix.

Dry-run preview

Preview everything without writing files using --dry-run (or -n). Medix shows:

• The discovered files and their output paths
• A representative ffmpeg command that would be executed
• The complete conversion plan

FFmpeg auto-install

If FFmpeg or ffprobe are missing, Medix detects your OS and package manager and offers to install them for you. Supported managers:

• macOS — Homebrew, MacPorts
• Linux — APT, DNF, YUM, Pacman
• Windows — winget, Chocolatey, Scoop
