🌸 MKVTOOLNIX-GUI(1) 🌸

okay so bestie, this is the mkvtoolnix-gui page from the User Commands manual section, and honestly? it's giving "i contain multitudes" 💅 because this one little app does SO much. let's get into it.

✨ NAME ✨

mkvtoolnix-gui — a GUI for mkvmerge(1) that also includes a chapter editor and a header editor 🎀

🦋 SYNOPSIS 🦋

mkvtoolnix-gui [[configuration-file-name.mtxcfg] | [source-file.ext] |
               [--info [matroska-file.mkv]] |
               [--edit-chapters [chapter-file.ext]] |
               [--edit-headers [matroska-file.mkv]]]

💖 DESCRIPTION 💖

mkvtoolnix-gui(1) is a Qt(TM) based GUI for mkvmerge(1). it also implements mkvinfo(1)'s and mkvpropedit(1)'s functionality — like, the whole friend group's powers in one app 😭 — and it will evolve to cover mkvextract(1) as well. all settings (e.g. source files, track options etc) can be saved and restored, so you literally never have to redo your whole setup. iconique.

so here's the tea ☕: if you list configuration file names with the extension .mtxcfg, the GUI loads those configuration files in the appropriate tool. any other file name gets added as a source file for multiplexing, or opened in the info tool, the chapter editor or the header editor — it all depends on the current mode, bestie. and you can change the current mode with --merge, --info, --edit-chapters or --edit-headers. the default mode is adding files for multiplexing. periodt.

⚠️ okay important heads-up: if an instance of the application is already running when you start the application a second time, all file names given on the command line are handled by the already-running instance. no cap. so don't be surprised when your second launch like, hands everything off 🫶

🎀 OPTIONS 🎀

  • --merge — every file name that follows gets added as a source file to the current multiplex job. this is the default mode, so if you do nothing at all, this is what you're getting 💅
  • --info — every file name that follows gets opened in the info tool. bonus: the info tool will be selected on startup instead of the multiplexer tool. slay ✨
  • --edit-chapters — every file name that follows gets opened in the chapter editor. bonus: the chapter editor will be selected on startup instead of the multiplexer tool 🎬
  • --edit-headers — every file name that follows gets opened in the header editor. bonus: the header editor will be selected on startup instead of the multiplexer tool 🧚
  • -h, --help — show usage information and exit. the classic "wait what does this do again" button 🫶
  • -V, --version — show version information and exit. vibe check passed, here's the number 👑
