Split mkv file with mkvtoolnix command line

I found mkvtoolnix command line, installed with brew. But i found nothing about splitting a movie with the command line, i only found with GUI.

The installation create 4 binary mkvextract mkvinfo mkvmerge mkvpropedit .

Solution

  • Either use the command line mkvmergewith --split (see https://mkvtoolnix.download/doc/mkvmerge.html) or use the GUI on the "Global" tab ("Splitting").

    For example, to split the file movie.mkv into 1.5GB chunks:

    mkvmerge --split 1500M -o movie-split.mkv movie.mkv

    Note that fractional split sizes aren't supported, so --split 1.5G won't work.
