How to demux a fullBD with UsEac3to?

Hi

I want simply demux a full BD using UsEac3to.

I do not want to recode. I just want to get the video streams, all audio tracks, all subtitle tracks and chapters.

Anyone know what key I should to push in the interface? Sorry for the idiot question.

After I will use MKVToolNix GUI for make a MKV file.
I want create a BDremux.mkv starting from a blu-ray structure on the hard disk (a personal backup of my Blu ray disc).

With a fast computer (4790k / SSD) how long is it supposed to take to do this process? BD of 40GB.

Is the m2ts file sufficient for this process? Or is the complete structure of the BD necessary?

Thank you!!

if the whole movie is in a single m2ts is enough

Nothing. These options are for construct a COMMAND LINE 'Add'ing one or more of them, when you need recode or modify some track.

If you only want make a BDremux.mkv without modify tracks you can load the movie .mpls in MKVToolNixGUI directly.
Or from your BD with MakeMkv

Thanks for the info. Yes, I only want make a BDremux.mkv.

I have been told that if I load the Blu-ray directly into MKVToolNixGUI it may happen that the audio and video are wrongly synchronized.
I have been recommended to use UsEac3to to make demux and then use MKVToolNixGUI to join audio tracks and subtitles.
In this way there will never be audio-video synchronization problems.

I need to be able to select several audio tracks and subtitles.

Is it right to do it this way?
Thank you!

This can be true with movies with many .m2ts files like is explained here.

eac3to, versions after 3.24, is the unique tool I know to correct the async when extract the audio tracks, but it is not a common problem.

Multi m2ts movies can also have other problems than need manual operation. For instance eac3to crash when a initial m2ts credit have a audio track diferent (stereo for instance) from the same track (5.1) in the main movie.

Thank you very much for the information!
I will consider it for my future remux!
First I will try to import the m2ts file with MKVToolNixGUI and if there is no synchronization problem everything is already correct.
If I see that the audio is poorly synchronized then I will use UsEac3to first and then MKVToolNixGUI. I guess that way I can solve most complicated cases of synchronization.

Thanks Master!
