Do any of you have any software you can recommend for removing unwanted audio tracks and subtitles? Some of my shows and movies have multiple, and the Roku app does not follow the users set default language, leading to it playing the wrong track when autoplaying.

I've tried unmanic, but its unfortunately too heavy for my server, just slows everything to a crawl.

mkvtoolnix and ~~handbrake~~ are pretty useful and powerful, you might try those

If you just want to remove audio and subtitle tracks, don’t use Handbrake. That will re-encode your video which will result in quality loss. Use MKVToolNix or FFmpeg to remux instead and only remove the tracks you don’t want.

Remuxing is also much faster and less cpu intensive than re-encoding.

Doesn't handbrake has an option to not re-encode the video ? But yeah totally agree, it's not worth it to re-encode everything just to remove audio tracks.

It didn’t when I last used it. But that was also years ago. The Handbrake devs were pretty adamant back then about not adding remuxing.

MKVToolNix did look like it could do a good job with this, but I have a lot of files that aren't mkv

I can't check right now, but I'm pretty certain I've used MKVToolNix to remove unwanted audio files from an mp4 before. However, the result will always be remuxed to mkv.
