Add/Remove audio or muxed subs

Mkvtoolnix
Next question please

I've done this with Avidemux many-a-time. Just load the file. Go into audio and select only the english audio track. Then on left side of the main menu select copy for both video and audio and select the correct muxer for whatever type of file you have. The whole process takes like 2 minutes tops.

Does it do anysort of re-rendering? I wouldn't want to lose any quality on my main video/audio tracks

audio tracks is easy
muxed softsubs as well
muxed hardsubs is impossible

Ffmpeg does it in a few seconds.

ffmpeg -i movie.mkv -c:v copy -c:a copy -map 0:0 -map 0:2 movie.mkv

Youd have to adjust the maps to match the tracks in video.
