BD3D2MK3D: Convert 3D BDs or MKV to 3D SBS, TAB or FS MKV - Support thread

[r0lZ]

What are people doing with these files then? Playing them on a media player?

Personally, I just need to connect a hard disc to my Samsung 3D TV, put my glasses on my nose, and launch the movie.

According to mk-will, you may have the same possibility, as your JVC can probably play the 3D directly. If you prefer to play it with your PC, you will have at least to select the right 3D mode on the TV when the movie starts, because as far as I know, the HDMI connection cannot inform the TV that the film is in 3D.

Hello, have dug these threads top to bottom and found no solution to my problem. Will be as detailed as possible below, appreciate any assistance offered.

So I have gotten as far as successfully ripping a 3D-MKV (had to run it through MKVToolNix because of some timecoding issues causing it to skip, but otherwise was completely fine). This MKV included both streams (AVC-H.264 and MVC), DTS-HD 5.1 sound, and Subtitles (not forced/not hardcoded). I've made it to the point of being able to create the project folder on my external hard drive, and encoding into a final SBS-MKV...

...HOWEVER, every single time I get to this point, the video becomes a green screen with no video after the 34 minute mark (there's still sound). I know it's not an issue with the original rip, as both streams are fine on the original MKV, the ToolNix fixed MKV, and the green screen is on BOTH streams after going through BD3D2MK3D (so it's not an issue with one track or the other, since it's happening to both of them).

I've tried every suggested troubleshooting solution. Turned off hardware acceleration, didn't work. Made it so neither my computer or harddrive can go to sleep during the process, didn't work. Tried with an ISO instead, didn't work. GPU/CPU is all up to date. Don't appear to have the option to turn off Hardware Decoding, though I'm not sure where that would be located within the software. No matter what I make my settings, it starts to encode normally during the second step... then when it's around 58% with an ETA of 49 minutes remaining, it speeds up and finishes in 10 minutes (and resulting green screen happens).

I have tried everything, and nothing has worked. I'm not a novice to disc ripping or more advanced file conversion, but absolutely nothing is making this work for me. I am willing to try anything at this point, and any proposed solution that I haven't tried is an appreciated suggestion.

Have you successfully done another BD, or do you have always that problem?
What is the movie?
Are you sure that your hard disk is not full?

This is the first Blu-Ray I've tried to do this for (The Day of the Doctor), and my disk space is far from full. There's still two Terabytes of available space, and this project/final file certainly can't be in that size range.

And yes, this problem is occurring every time. The original MKV doesn't have the green screen issue in either stream, it's only happening after converting through BD3D2MK3D. Like I said before, once 3D_Encode_Launcher is launched (usually click to automatically do this), it gets to 58% before suddenly speeding up and finishing in only 10 minutes.

EDIT: I should also mention the final file size ends up being 3 GB. Realize that's probably not normal for a film that is 1h19m, even at reduced size (with the MVC, its original MKV is 30GB). The part of the first half, where it extracts the MVC stream, only takes 2 minutes... not sure if that's strange. The weird ETA of 49 minutes suddenly changing to finishing in 10 minutes only ever happens in the second half (encoding the final MKV), so I'm thinking it has to be some kind of problem on that end.

I assume you've regenerated a complete project after disabling hardware acceleration. Correct?
This is important, because the GUI option only slightly modifies the avisynth script, which must be recreated (or manually modified) for it to have any effect.

Unfortunately, I can't think of any other reason for this bug. I'll think about it some more, but there's no guarantee.

Yes, I have created a new project each time.
Totally understand, this is probably some strange unique fluke /=

The only thing I haven't tried or considered... I normally take great care in handling my discs, but I recently let someone borrow this disc. Last night I noticed thumbprints on it (nothing I couldn't carefully clean off), and I'm wondering if that could have created some anomaly that got copied onto the MKV which is now creating this problem.

I somewhat doubt that's the issue, since apart from skipping (which MKVToolNix fixed) the original MKV played fine, and the typical "read failure" error that comes up in MakeMKV when there's smudges on the disc didn't come up during ripping either... but I'm going to rip a new MKV from scratch and see what that does, just for the heck of it/to see if that changes anything.

[r0lZ]

Good idea. Indeed, fingerprints on the disc could be responsible of the original problem. The fact that the BD plays fine is not a guarantee that it is clean, because the error correction might be sufficient to hide the problem, but not sufficient to allow to rip it successfully. However, I suppose that MakeMkv or Mkvtoolnix should have complained in case of a fatal error. Anyway, let us know if re-ripping the BD solves the problem.

BD3D2MK3D v1.34 released

V1.24 is here. It's not a major update, but it fixes a few little bugs, and it includes the newest versions of the third-party tools.

v1.34 (January 6, 2024)
- Fixed a few very little bugs
- Wraped with the latest version of freeWrap (v6.75)
- Updated tsMuxeR Open Source to the latest version (git-7f8667d 2024-06-06-02-00-53)

- Updated x265 to the latest version (v 4.1+54)
- Updated mkvtoolnix to the latest version (v89.0 'And the Melody Still Lingers On (Night in Tunisia)')

As usual, you can download it here: BD3D2MK3D.7z

Note that this version has been only slightly tested. If you encounter any problem, you can still download v1.33 here.

[La Samourai]

Right, so after cleaning the smudges my friend left on the disc and re-ripping, then trying again... the green screen is still happening, but now it's at a different place in the film. The overall majority of the film is totally fine, until the last 20 minutes when it becomes a green screen.

Really stumped on this one. Just for the heck of trying everything, when I ran it through MKVToolNix -- to fix the earlier timecode error on both rips causing tsMuxerGUI to fail -- I created both a multiplexed MKV with chapters and one without chapters. Just in case that somehow factoring into the earlier problem with tsMuxerGUI/timecode could have caused this whole problem.

I've tried it twice so far (green screen at the end both times unfortunately) but only with the one WITH chapters. Will try again tomorrow, see if the one without chapters is more successful. But yeah, only the VERY END of the movie being erased by green screen is definitely an improvement over 57% of the entire runtime being erased by green screen.

[r0lZ]

Honestly, I don't think that the chapters are concerned. They are only metadata in the little MPLS file, not related at all to the video stream.

The fact that cleaning the BD has an effect means that the problem is probably due to the disc. Maybe you should clean it again and retry one more time?

[La Samourai]

Yeah, unfortunately upon further inspection it appears my friend left a circular scratch right in the center of the disc (which is probably close to the end of the film/where this current rip keeps creating the green screen issue).

So yeah, not a problem with this app, unfortunately I just have a bad disc /=

Unable to afford getting a new one, sadly. Will try using FRIM and FFmpeg to manually extract both streams, then export those from AVISynth+ as SBS (since that now seems to be my only option).

[r0lZ]

Will try using FRIM and FFmpeg to manually extract both streams, then export those from AVISynth+ as SBS (since that now seems to be my only option).

That's almost exactly what BD3D2MK3D does, except that it doesn't use FFmpeg. Not sure you will obtain a better result.

BTW, have you seen my PM ?

[RickSterOH]

Apologies if this is not the correct area or if this has been posted before. I searched but could not find any issues that resemble what I'm seeing. I'm attempting to process a MKV file using version 1.34 and the resulting MKV does not have any audio. The log file contains this error:

Streams demuxed by tsMuxeR:
Error: Can't rename "Tangled3D_t02.track_2.dts" or "Tangled3D_t02.track_2.dts" to "MKV3D.track_2.Eng.dtsma": error renaming "Tangled3D_t02.track_2.dts": no such file or directory

The problem here is that the tracks could not be found because they were created as "Tangled3D_t02.track_2_eng.dts" ("eng" is added)

I've ran through this process so many times thinking I was doing something wrong because this is my first attempt at using this tool. Please let me know if this is a bug or if I'm making a newbie mistake.

Thanks

FYI, I downgraded to the v1.3.3 version and this was no longer an issue.

[r0lZ]

Oops, apparently, something has changed in tsMuxeR that BD3D2MK3D doesn't know! I will have a look. In the meantime, as you did, I recommend to use the previous version (v1.33) available here.
Thanks for the notification. As I wrote, I have not tested the latest version carefully.

[r0lZ]

Indeed, due to important changes in tsMuxeR, BD3D2MK3D v1.34 doesn't work correctly. I have removed it from the download server. I am currently fixing it, but that may take some time. In the meantime, use v1.33, that can still be downloaded here.

BD3D2MK3D v1.35 released

Hopefully, the bug related to tsMuxeR is fixed. Sorry for the inconvenience.

v1.35 (January 11, 2025)
- Fixed a big bug in v1.34 due to different output filenames in the latest tsMuxeR. Sorry!

[Ennio]

Hi r0lZ,

When starting latest version 1.35 I surprisingly get a message saying
"It seems that your pc is currently configured to go to sleep or hibernate after a certain delay..."

I checked my pc's power settings but I'm using "High performance" with "Put the computer to sleep" set to "Never".

Any advice?

[p.hennessey]

I have tried — and failed — to make an MKV 3d movie from a 3d blu-ray that actually has working audio.

I am not trying to do anything special or weird. This is my copy of Tron Legacy in 3d. I used MakeMKV to make the original video file, which I confirmed DOES have audio (played in VLC with audio) before bringing it into BD3D2MK3D for encoding. This is where it fails.

I have tried exporting with 5.1 and stereo, and just stereo. I have tried both AAC and AC3 encoding. I can even see the ac3 audio file in the project folder that BD3D generates.

Yet... the MKV file that BD3D generates has NO audio track. I have tried exporting 4 different ways now, and they all failed.

NO idea what I'm doing wrong, extremely frustrated why this is so difficult. Cannot find any thread or information on how to actually make this work. Am I missing a step?? Isn't this tool supposed to automatically add the audio tracks? Why would this be disabled by default? Who wants a movie with no audio??

(BTW...BD3D2MK3D would be a hell of a lot more useful if it had a "test" mode where it exports 2-3 mins of the movie so you can troubleshoot. As of this moment, I have to wait 30 mins between attempts.)

[r0lZ]

Are you sure you are using the latest version v1.35?
What you describe is exactly the bug of v1.34, reported just a few posts above, and fixed yesterday.

It is not possible to do a quick test, as demuxing and processing the streams must be done completely anyway by tsMuxeR and eac3to. But you can edit the __ENCODE3D.cmd file to modify the number of frames to encode. That way, you can test if the video quality is good and if the streams are correctly muxed.

[r0lZ]

When starting latest version 1.35 I surprisingly get a message saying
"It seems that your pc is currently configured to go to sleep or hibernate after a certain delay..."

Hi Ennio !
That message is often shown when the program is used for the first time. I know for sure that it's not your case, but perhaps the file containing miscellaneous flags used by BD3D2MK3D has been removed or damaged?

Also, if your PC has crashed during an encoding, it is possible that the sleep setting has been restored to a bad state.

I don't remember exactly what BD3D2MK3D does to check that setting, but I will verify here and let you know if there is a bug. I don't think so, as I have not modified that code since a very long time, but perhaps something has changed in Windows? Anyway, that message should be shown only once and don't worry, it is harmless.

[EDIT] I remember more or less what I did. Everything is explained in the Settings -> Power Plans menu. I suggest to verify your current Windows settings (you can open the Power Options control panel from the BD3D2MK3D menu) and set the main option to "Do not change the power plan when encoding". In your case, you can launch __ENCODE_3D_LAUNCHER.cmd or directly __ENCODE_3D.cmd, as if the Windows power plan is High performance, both methods are equal.

[p.hennessey]

@r0lZ — Thanks, I'll try the latest version. I was able to hack this to work by editing the _MUX_3D_OPTIONS.json, and forcing it to include the audio file information. That did the trick.

[p.hennessey]

Windows Defender says a virus was detected in the portable version.

[r0lZ]

Windows Defender is probably the worst antivirus. False positives are its speciality! Verify with VirusTotal.

I have also scanned BD3D2MK3D.exe and the whole preset folder with Windows Defender, and here, it detects nothing. Are you sure you don't have a virus on your PC that might have infected BD3D2MK3D ?

Oh, and there is only one version. Call it portable if you want. Have you dowloaded it from the official BD3D2MK3D home? (use the link below in my signature)

[p.hennessey]

Well, I can't figure out how to disable it. Using Google Chrome, and Windows Defender refuses to even allow me to download it.

Full disclosure: I'm not a Windows guy. I don't know the obvious tricks, and I may need some more hand-holding here. How do I force it to allow the download?

Edit: Just disabled the virus scanning. That allowed me to download it.

Your new version works! Audio settings are now appearing in the json file. Still encoding, but this bodes well. Thanks for the quick replies!

Thanks for the thanks.

[r0lZ]

Edit: Just disabled the virus scanning. That allowed me to download it.

And you can use it with Defender enabled? That would mean that there is no virus in the exe, and that only the 7Z archive is wrongly suspected. Or perhaps the problem is due to Chrome? (I don't use it as IMO Chrome IS a virus! I prefer Brave, based on the same code, but free of the Google spies.)
