Batch Mkvmerge change default audio, subitle + delete audio

[alloar]

Hello !

I'm really a newbie and I don't understand a think about batch and mkvmerge...

I have a serie on my computer (let's call it SERIE). SERIE is about 220 episodes.
Each file is dual audio, but the default audio stream is useless for me and I would prefer to set the second by default AND have the subtitles by default too.

So :
- Delete the current default audio
- Set the second audio as default
- Set the subtitles as default

My files are named "SERIE - 001 name of the episode.mkv" to "SERIE - 220 name of the episode.mkv
They are located in D:\SERIEFILE\
The ID of each track is :
ID 1 : Video
ID 2 : Audio (the one I'd like to delete)
ID 3 : Audio (the one I'd like by default)
ID 4 : Subtitle (I'd like by default)
My Computer run on Windows
The Folder for good episodes is D:\SERIEFILETOP\

If a person on this forum could help me doing a batch, because doing this for each episode one by one takes too much time...

Thank you in advance for your help, and have a great day/night.

for %%a in (*.mkv) do mkvmerge -o "output\%%~a" --audio-tracks 2 --default-track 2 --default-track 3 "%%~a"

Note: mkvmerge starts counting tracks at 0. See IDs via: mkvmerge -i "file.mkv"

MKVBatch. Set custom audio/subtitle filters if needed.
