Subler--Metadata Automation--CLI

[swampdaddy]

I use Subler on the Mac to edit certain existing metadata such as movie name and comments using the existing GUI. Now I would like to automate this process, possibly with Python. Is there a Subler version that can be executed via the command line? Or is there another library that could be called upon to write metadata to .mkv or .mp4 files?

Cannot answer about Subler and MP4, but the header editor in mkvtoolnix has a CLI interface, and is available for Mac. For MKV files, profedit can change just about everything.

See Command line MKV header editing if you're interested in what I went through learning about it.

In Terminal, I use mkvpropedit (https://mkvtoolnix.download/doc/mkvpropedit.html), part of the MKVToolNix tools (https://mkvtoolnix.download) to modify the metadata of my .mkv files. I installed it via Homebrew (https://brew.sh).
