Part 3. FAQs of MKV Merge

1. Can I merge MKV files with HandBrake?

When it comes to converting and editing videos, many people may think of HandBrake. But unfortunately, it doesn’t support merging videos at present. So, the answer is no. You cannot use HandBrake to merge MKV files. If you want to merge media files, you can try the methods we have introduced - Aiseesoft Video Converter Ultimate and MKVToolNix.

2. What is mkvmerge?

It is part of the MKVToolNix package. Mkvmerge can help you merge different multimedia files and save them as one MKV file. But it is a command-line program, which can be hard for some users to operate. So, here comes mkvmerge GUI (also known as mmg), a simpler version of mkvmerge with an intuitive interface, which makes the combination much easier.

3. Does MKVToolNix reduce quality?

No, MKVToolNix does not reduce the video quality of your files after multiplexing. If your video is in high resolution, you’d better use a professional HD video player to play the files. Otherwise, there may be quality loss during the playback.
