make sub default

[ghazalo]

for %%a in (*.mkv) do mkvmerge -o "output\%%~a" --default-track 2 "%%~a"

hello there
the script above doing well with me making the sub default ,but I wonder always it must copy to new folder (I mean it cannot be a quick action within the video file without wasting the time of copying to a new video again?)

of course I am talking about series with 99 ep and every ep around 1GB, this a long time to copy

You could use mkvpropedit (https://mkvtoolnix.download/doc/mkvpropedit.html) instead of mkvmerge to do that.

Doesn't the 'Example'-section cover what you want?

no there is removing tag switch flag ...etc but there is nothing saying making track# default

section 6 (examples) right?

Did you actually read what is written there?

mkvpropedit movie.mkv --edit track:s1 --set flag-default=0 --edit track:s2 --set flag-default=1

This removes the default flag from subtitle track 1 and sets if for subtitle track 2,
for audio tracks:

mkvpropedit movie.mkv --edit track:a1 --set flag-default=0 --edit track:a2 --set flag-default=1

this would remove the default flag from audio track 1 and sets if for audio track 2.

Note the comment:

Note that mkvpropedit(1), unlike mkvmerge(1), does not set the 'default track flag' of other tracks to '0' if it is set to '1' for a different track automatically.

So if you do not want to end up with multiple tracks flagged as default make sure to disable the default flag for other tracks.

ok thanks it just this flag thing confuses me
so
default=1 that's on
default=0 to the rest that's off
right?

so what equivalent to make full folder as my request in the beginning
for %%a in (*.mkv) do mkvmerge -o "output\%%~a" --default-track 2 "%%~a"

[Selur]

You select a track using '--edit track:..' you then set disable the default flag with '--set flag-default=0' or enable the default flag with '--set flag-default=1'.
You should read the whole page if you want to understand things.
