The Nut Job 3D - Which Playlist or segment map?

I have the US Retail combo pack of BluRay 3D/BluRay/DVD/Digital HD (Ultraviolet) and I'm trying to figure out which playlist is correct for the 2D version of the film.

After ripping on Linux with makemkvcon (automated), I get basically two files that "might" be the movie:

00800.MPLS and 00801.MPLS

Each file is approximately 19.1GB after ripping.

When I look at the disc with MakeMKV (GUI) on my Mac, those two playlists show the exact same duration, but differ as follows:

00800.MPLS -> Segment Map 800 -> 20 Chapters -> 1:25:54 -> 18GB
00801.MPLS -> Segment Map 800/50357 -> 20 Chapters -> 1:25:54 -> 30GB

I used ffmpeg to transcode the two MKV files into a SINGLE mp4 with the movies side-by-side. I then scrubbed through the entire movie in a few minutes looking for visual differences and saw none. After reviewing the reported size and segment map differences, I'm theorizing that Segment 800 is the move and Segment 50357 maybe has the 3D effects? And that would mean that 00800.MPLS is the right playlist?

If anyone has any definitive information for this title, I would appreciate it.

Thanks!

Look at the titles and credits - those are where Disney-released movies differ. Everything is the same, except 800 will have English titles and credits, and 801/802 use French/Spanish titles and credits.

Why 801 indicates being so much bigger than 800 is strange; they should be about the same size, which is what you found after ripping.

It's not a Disney movie, and I did a complete side-by-side visual comparison - NOTHING appears different.

The size difference is extrem.

Things to check:
- Check what audio and subtitle tracks are included by expanding the title list in MakeMKV. Some titles (MPLS) have only limited audio and subtitles included (f.e. only Japan tracks)
- Check the segment map (the parts of the stream elements) shown in the lower right window of MakeMKV for the two MPLS if the title is selected. If they are identical, the video stream is the same, only the audio and subtitle tracks differs due to different MPLS selections.

I -INCLUDED- the segment map information.

After mixing the two ripped movies together for side-by-side viewing, there is NO DIFFERENCE in what you see or how long it plays. That flies in the face of the 00801.MPLS playlist having an additional segment AND being about 75% larger in estimated size. Still, the "before rip" info does show that they are the exact same length.

To find out what is behind the Segment "50357" (size and content) you must create a Decrypted backup and select the "50357.m2ts" file in the "Stream" folder.

Have you expanded the two titles and checked what is the difference (audio and subtitle track)?

"Backup Failed" is all I get for output whether I ask for decryption or not. And, it's pretty much right away - it doesn't try to do anything at all.

As far as differences when expanding the titles:

00800.MPLS and 00801.MPLS are identical except for one thing... 00801.MPLS has a "subfolder" under Video that is listed as "MPG4-MPC-3D" and 00800.MPLS has no subfolder under Video at all. It shows only the MPG4 Video folder itself.

The 3D info would explain the displayed file size difference, and the actual extracted files being virtually identical in size. By default, MakeMKV doesn't grab the 3D information.

I agree.

Why will it not back up the disc, though?

What error does it give when the backup fails? If you have debug logging turned on, there should be more information on WHY it failed.

As stated above... "Backup failed."

Debug as follows:

Code: Select all

DEBUG: Code 195 at K"bG+2THYoFa3gj|%MT:29405545
