Mp4 + .ass = mkv?

[Tyestor]

Hey guys, quick and simple question regarding mkvs. I was wondering if it was possible to mux the MP4 + .ASS sub file to mkv without re-encoding i.e not losing any quality? Thanks.

mkvmerge

Thought so. I already have that and I have used it for other things just wasn't sure if you could use it with a non-mkv file or if it would end up horribly destroying the video quality. Thanks :)

EDIT: Hmmm, why is the filesize smaller as an mkv?

Ever heard of container's overhead (http://en.wikipedia.org/wiki/Digital_container_format)?
