Will muxing a video to an mkv file using mkvmerge result in quality loss?

Just to be sure, I wanted to ask.


Will muxing a video to an mkv file using mkvmerge result in quality loss for the video? Even just slightly? or It would not affect it at all?

You're changing containers, if something happens to the actual video data, something is definitely wrong.

He's trying to say: It should not affect quality at all.

Ohh.. thanks!

And thanks for clarifying it too neuron :D

Oh btw, does this apply if I extract the same video that is now inside the .mkv container, and mux it again to another .mkv file? Still no quality loss?

Do you lose information extracting stuff from (say, a .7z) archive? No? ;p

There MAY be trivial changes in the stream's header, but no effect on quality. The stream itself remains unchanged.

While video quality per se does not change, each container has its own requirements. For MKV read here (http://forum.doom9.org/showthread.php?t=165188).
