Convert M2TS file into MKV without any quality loss

[rocknrolla115]

Ok, so i have a M2TS file of a movie that i want to convert into MKV so that i can remove all unnecessary audio & subtitle tracks (I use MKVtoolnix for this) but how do i go about to make this conversion? It`s very important that there is no quality loss whatsoever.

Is it possible to do?

Drop the M2TS onto MKToolnix GUI?

Ok, i didn`t know that this software supported M2TS as input. Will give it a try.
Thx

You could also use tsMuxeR GUI to mux to a ts/m2ts file and remove unneeded tracks.

Easiest way for me is open m2ts file in avidemux, copy video, copy audio, output format MKV and then save.
But mkvtoolnix support m2ts files, so if you dont want convert f.e. audio to lower bitrate then Mkvtoolnix is easiest way.

Hey Bernix, you seriously made my days! I signed up just to thank you man. Really appreciate it.

I wanted to do to same convertion. I tried quite bunch of softwares advised here and they all failed badly (mkvtoolnix and tsmuxer are included). Some of them can't even recognise the .m2ts file.
Few searches later then I saw your reply... And avidemux works like a charm. Like you said, I keep original video and audio then save the file as mkv. Job done in seconds.

Thanks again, have a nice one.

Wrapping the .m2ts file in a MKV container using mkvtoolnix should work, I've done dozens of .m2ts files with out any problems, quick, no re-encoding or change of quality.
