video lossless conversion using Avidemux

[zoran]

How do I convert an .mkv video to .mp4 using Avidemux 2.7.1 but without losing quality? I think this lossless process is called rewrap, if it rings any bells

remux is the word you look for. Open the file.mkv choose the copy option for the audio and video, with mp4 muxer for the output format. Then save it to new file. I just did it here it takes a few minutes on my machine with a 6 core 9600k and 32gb of ram.

I like mp4tools, the interface isn't the most modern but it does what I need (stream copying) and it supports mkv files as input.
