Merge 2 MKV files ?

Nico8583 · 21st February 2015, 17:27

Hi,
I have several films with 2 parts (because my original Blu ray is splitted into 2 discs) and I would like to merge both. Is is possible with mkvtoolnix ?
I've seen Append button, it seems to merge audio, video and subtitles, is it true ? But what about chapters, attachments and tags ? I must edit manually ?
Thanks !

Yes, it's possible, yes, similar tracks are merged, although it will throw up a warning if it suspects they may not be compatible (different Codec Private Data).

Chapters will be merged. All Attachments should be added to the file.

I don't believe anyone on earth knows how Matroska Tags work. No one should be using them, but yes, all global tags should be added to the output file as new global tags, which is probably the wrong thing to do.

Thanks !
I'll try with 2 MKV files (same movie in 2 parts, same video codec, same audio codec, same subtitles formats).
But if chapters can be merged (first chapter of 2nd file will start with an offset equal to first file length ?) and subtitles also (same than chapters), it would be a good thing !
