Ocean is correct. BDedit v0.58b12 is the latest version.

Hi everyone,
I've been working with Blu-ray discs of TV series and trying to get MakeMKV to recognize each episode as a separate title, rather than bundling them into one large MKV file. I've had some success using BDEdit to modify the playlist (.mpls) files and wanted to share my process and ask a few questions.

Specifically, I'm referring to the column labeled 'c' in BDEdit's “Playlist” tab.

Typically, when I open a BDMV structure of a series disc in MakeMKV, all episodes from a particular playlist are grouped into a single, long title.
Through some experiments of mine, I have managed to get MakeMKV to show all episodes as individual files through the following:

1. Opening the .mpls file in BDEdit.
2. Changing all the '5' values in the 'c' column for the relevant PlayItems to '1'. So, the sequence becomes 1, 1, 1, 1.
3. I then temporarily remove one of the episode stream files (e.g., 00001.m2ts) from the BDMV/STREAM folder.
4. When I then open the (modified) BDMV in MakeMKV, it lists the episodes as separate titles.

MY Questions:

Is this a "bad" or risky practice? Modifying the connection condition like this is significantly faster for me than ripping a single large MKV and then manually splitting the episodes later. (Using MKVToolNix for example). Could this result in any audio issues or similar problems?

Why the 1, 5, 5, 5… pattern?
I come across this often, where the first episode on a Blu-ray is 1, and the rest 5.
My understanding is that '5' signifies a “seamless” connection, causing subsequent PlayItems to be treated as part of the same continuous block by players (and MakeMKV). '1' seems to signify a “not seamless” or standard forward connection.
Why would a disc be authored with the first PlayItem in a sequence having a connection condition of '1' to the next, while subsequent PlayItems within that same logical block use '5' to connect to each other? What is the technical or authoring rationale behind this 1, 5, 5, 5 pattern for a series of episodes intended to be playable as a “Play All” block?

I'm trying to better understand the underlying Blu-ray playlist mechanics. Any insights, corrections to my understanding, or answers would be greatly appreciated!

If a PlayItem is the first PlayItem in a PlayList or a PlayItem in a PlayList whose PlayList_playback_type is not set to 1 (Sequential playback of PlayItems), the connection_condition has no meaning and shall be set to 1.
In other cases, the meanings of the connection_condition are defined in the following.
connection_condition=1 – This connection is not meant for seamless connection.
connection_condition=5 – This connection is meant for seamless connection.

Sorry for the late reply, but thank you for the explanation!

I'm having a problem with a cut. Specifically, with Criterion's cut of "Dead Man."

I'm using TsMuxer to add/replace audio tracks and subtitles.

The whole process runs smoothly except that it adds HDR10 metadata to the original SDR, completely ruining the image.

I've tried to fix it with BDedit (*mpls and clpi*) but it doesn't work.

I've run the authoring process a couple more times, and it always gets the same result.

Can anyone help me figure out what the problem is?

Thanks.

taurusus · 24th December 2025, 14:23

Hi palestina.
Which version of the movie do you have, UHD or Blu-ray?
Which version of tsMuxeR are you using?

palestina · 24th December 2025, 17:49

Hello.

I'm using the US edition (CRITERION).

The version of TsMuxer I'm using is the latest (2.7.0).

Thank you very much for your interest.

taurusus · 24th December 2025, 19:18

If the original has HDR 10, why should it be missing from the edited copy?
Metadata can be deleted in BDedit in the ExtensionData tab.

palestina · 24th December 2025, 20:17

The original is SDR. Authoring with TsMuxer produces a copy with HDR10.

If I remove the HDR metadata with Bdedit, the image quality is poor.

What I don't understand is why it creates the HDR layer if the original is SDR.

Screenshots attached.

HDR ===== AUTHORSHIP

SDR ===== ORIGINAL

taurusus · 24th December 2025, 20:32

Did you set the SDR in the STN tab as in the original?

palestina · 25th December 2025, 02:38

Yes. I've switched from HDR to SDR in BDedit's STN, but the result isn't good. Black screen and the player freezes.

What I'd really like to know is why this is happening (I don't think it's the first time).

I've even tried authoring without adding/replacing any audio tracks and/or subtitles, and the same thing happens. The m2ts file is HDR instead of SDR.

taurusus · 25th December 2025, 04:43

Did you create only an m2ts file in tsMuxeR and replace it, or did you create a complete Blu-ray structure with mpls and clpi files and replace them all?

ocean · 25th December 2025, 05:56

Hi, happy holidays to everyone.

@palestina

Try reading the original 00001.m2ts with Mediainfo.

palestina · 25th December 2025, 11:31

I've created a Blu-ray structure using m2ts, mpls, and clpi.

I've attached a screenshot of the BDInfo.

P.S. I hope you all have a good day.

ocean · 25th December 2025, 13:57

HDR Format is SMPTE ST 2086 static metadata: HDR10, color space BT.709

palestina · 25th December 2025, 16:51

So, if it has HDR metadata, why does BDedit recognize SDR?

I can't understand it. Nor can I understand why my LG recognizes SDR when the original is played, but recognizes HDR when the edited version is played.

Thanks for your interest, @ocean.

Best regards.

I checked how tsmuxer puts together the movie "Dead man".
If you check in BDedit, then indeed in the STN table the data of the original video in SDR has been changed to HDR,
but the data in mediainfo has not changed and the video itself does not visually differ from the original.

Hi taurusus.

The problem is that the OLED outputs it as HDR, and the playback isn't correct. I suppose it's something that can be fixed by changing the panel settings.

Ocean told me that this issue doesn't occur when using Scenarist, so I'll try it that way.

It's a bit complicated for me because I've never used it before... but it'll be good practice.

Regards, and thanks for the help.

palestina · 28th December 2025, 15:09

Edited with Scenarist and now it respects the original SDR format.

Thanks again for your interest.

Best regards.

I have made a blu-ray with TMPGEnc Authoring Works 7. The blu-ray has six tracks. The topmenu points to the 6 track menus. But I would like it when two of them would bypass the track menu and start playing the video without first going to the track menu. I see no option to do this within TMPGEnc Authoring Works 7. How would I go about it to change the blu-ray menu with BDedit to make this happen?
