Default track name?

Hi! I have a ton of audio and subtitle tracks I want to add to a single video. MKVToolNix detects the audio/subtitle language in the metadata/filename just fine. However, I like also writing the language in its original name in the track name— so the Japanese track is named 日本語, the Simplified Chinese 简体中文 and so on.

Is there a way to do this automatically? As I said, there are tons of tracks, but I also have to do this +20 times for different videos. Is there a way for MKVToolNix to assume es’s name as Español or any other alternative?

Thank you so much!

Welcome!

Not with the GUI, no. You could write a script in e.g. Python or any other scripting language out there that uses mkvmerge for that, though.
