How to select specific segment map / M2TS to create MKV?

[mgutt]

If a disc contains multiple relevant titles but differ only regarding their intros, it would be nice to create MKVs only for this specific segment maps. Is that possible?

[Grauhaar]

Go to the titles without chapters (Titles with chapters are assembled from an MPLS Playlist). The titles without chapters are the m2ts segment files, normaly sorted ascending. Look at the "Soruce filename: xxxxx.m2ts" where xxxxx is the segment number. Don't forget to adjust the minimum title length.

Sadly there is no other title containing the single m2ts parts of the movie. I'm using a length of 120 seconds and the movie has three parts so at least one should be there, but isn't.

No idea how MakeMKV creates the title list. The above works for me on some Blu-rays.

Anway, the ultimate solution is to use the Backup function and view the elements in the STREAM folder. This works always.

Yes, but this takes a way to long for such small clips. I will post it as a feature request.

unless it has seamless branching

unless it has seamless branching

Seamless branching is only used on DVDs, the segments are inside the VOB files. But Blu-ray has the Playlist with the list of stream segments which are stored in the STREAM folder.

Yes, but the backup on HDD can be used to create the mkv file by open the index.bdmv file. The fast track to create the wanted mkv file.

Yes, but it's still much slower because it backups really everything.

It depends And as told, the title selection solution works for some disc, so the full backup option is only needed as an worst case scenario. And not many Blu-rays uses Multiangle.

With my new Libredrive enabled drives I can rip Blu-rays with 6x-10x speed. In most cases the rip completes in 10-20min.

i see i thought it was still called seamless branching when the movie is not in a single m2ts file.

MakeMKV still calls it "seamless branching" in the status window.

I don't know if there is any "term" for this technic used on Blu-rays. Best is like "Seamless Segment Selection"

Seamless branching was establised for the DVD VOB files, bcecause all data must be in the (up to 9) 1GB VOB files. So the segments are put all into the VOB files and the jump (branch) is done like a Chapter mark jump from one segment to the other segment (seamless) inside the VOB files. But for Blu-ray, the segments are no longer stored in one big file, each segment is a single stream element segment file (video and all audio and subtitle tracks), so the player read the stream element selection table from the playlist and simply select the stream element files until the end of the table has been reached.

Same process, but with an complete other implementation.
