I’ve got some raw BD files. What tools can I use to convert them into a more familiar format? (lemm.ee)

So I’ve got a rip of the Japanese Blu Ray of Evangelion, and I’d like to turn it from a jumble of numbered .mts files into something more useable. How do I get started going about that process? As an example, if I download a raw CD rip, I can use cuetools to turn it into a list of .flac tracks ready for listening. Is there some similar software (or multiple programs) for Blu Rays? I’m not really familiar with working with .m2ts files and don’t know where to start

EDIT: makeMKV worked (just to test, handbrake did as well, because the version I have has no DRM, but bear in mind that HandBrake is going to transcode/compress the resulting file by default). This turned the contents of the disk into 1 MKV file, which I could then run through MKVToolNix and split into individual episodes

eac3to will let you extract the mt2s files into their individual parts (video, audio, subtitles). You can then use mkvtoolnix to remux them into an MKV. MakeMKV works fine imo, but I read some vague waffling on a private tracker forum that it messes something up that eac3to doesn't.

Oh interesting. Did they say what that could be?

Found it

Why eac3to and not something like MakeMKV? Yes, MakeMKV is really easy to use because it's basically a one-click program. However, it does have its shortcomings when it comes to detecting and correcting authoring errors on Bluray discs.

Take that for what you will I guess. They didn't elaborate at all.

If you're interested in using a command line tool to demux, you can get it here, at the original thread on doom9.

Thanks for following up! That’ll be good to know to have an alternative at the very least
