Assistance needed to change subtitles with MKV Merge

[jarod1005]

Greetings,

I am in need of serious help on how to change subtitles in a video file. Basically, I want to change the subtitles to English. I am downloaded and installed MKV Merge GUI. I had the latest version at one point, but I installed an older version (v8.2.0 32 bit.) I have also used a couple of tutorials from YouTube that did not work. The language did not convert to English.

Here are the links which I followed:

I can change the audio to English with MKV Merge GUI, but I have been unsuccessful in setting up the English subs.

Please assist me with this taxing matter.

Thank you.

You need to set the English subtitles track as the default one (flag = Yes).
