Overall, I had a good experience with MKVToolnix! The file conversion was smooth and didn’t take long at all. The options for audio and subtitles were great. Just a little confusing to figure out at first. But eventually got the hang of it!

Wow, just wow! MKVToolnix completely transformed my video files! I can't believe how fast I was able to customize them. It’s super simple to use, even for noobs like me! Feeling super accomplished once I figured it all out. I’m never going back to other apps!

This app is an okay tool, but I struggled a bit with the complexities. I liked the merging features, but some of the options were hard to understand. I think it has promise, just needs a little more user-friendliness. I might keep using it.
