Well, great! I was actually a bit concerned that I just didn't understand something and that I was asking a stupid question.
Is there any way for the GUI to remember settings like that? To set those checkboxes to the same setting as you chose last time? (The other one that would be handy is the "720p" option on page 5.) Thanks again for this fine program! I'm excited about the MKV option, because then I can move the ISO images to MKV files! Kevin |

The settings from the Settings menu are saved immediately, as you change them. The configuration of the pages 2 and 5 (or at least the settings that are not BD dependent), including the audio conversion and the 720p options, are saved with "Save Settings Now", at the bottom of the Settings menu. They are also automatically saved when BD3D2MK3D is closed if you have ticked the option "Save Settings on Exit".

First, sorry for my English, if something ist wrong...
I found your App and it it's really great. I have some 3D-MKV Files, made with makeMKV and i want your Tool to convert them into the right 3D-MKV-Format. Can you or someone else tell me or show me where i can find the Info what i should select "Left View in AVC Stream" or "Right View in AVC Stream" to convert the File correctly? Can i find the Info in tsmuxer GUI when i open die 3D-MKV File made with makeMKV? But where? Same question with the 3D-Plane Option. Thanks a lot.... Triple-M |

How to find the view order and 3D-Plane numbers for a 3D-MKV created with MakeMKV
Welcome to the Doom9 forums, Triple-M !
Unfortunately, currently, it is not possible to find the information about the views order and the 3D-planes in the 3D-MKV file. If that was possible, BD3D2MK3D would retrieve it for you. We have asked the authors of MakeMKV to add that information in the file, and we hope that the next version of MakeMKV will correctly set the stereoscopy mode in the MKV header and will implement tags for the 3D-planes. When that will be the case, BD3D2MK3D should be able to recognise the info, and you will not see the red warnings any more. In the meantime, the only way to retrieve the info is by examining the original BD3D, with BD3D2MK3D or with tsMuxeR. When you load a BD in BD3D2MK3D, you can see something like this: Code:
Video : Und AVC, 1080p, 23.976 fps, left-eye Video : Und MVC, 1080p, 23.976 fps, right-eye (32 3D-Planes) Audio : Eng TrueHD, Multi-channel, 48/96 Khz Audio : Fra TrueHD, Multi-channel, 48/96 Khz Subtitle: Eng PGS, 3D-plane: 1 Subtitle: Fra PGS, 3D-plane: 2 Subtitle: Esp PGS, 3D-plane: 3 Things are very different for the 3D-Planes. In many BDs, the order of the subtitle streams determine the 3D-Planes numbers, like in the example above. But note that the first 3D-Plane is 3D-Plane #0. Here, the plane #0 is not used, and the first subtitle stream is associated with the second 3D-Plane, #1. The rest is logical. Unfortunately, there is no well established rule for the assignment of the 3D-Planes. The 3D-Plane #0 may or may not be used, and the order of the 3D-Planes may or may not be sequential. It is therefore almost impossible to deduce the 3D-Plane to use without examining the BD. However, it is possible to use a good 3D-Plane without knowing the original assignment. Here is how. You should try to assign a number that *may* be correct, and let BD3D2MK3D create the project. When the project is finished, you will find the 3D-Planes in the project directory, and the subtitle streams you have converted in XML/PNG format in sub-directories with names similar to this: 00801.track_4610.Fra.3D_2D. Now, use Subtitle Tools -> Verify 3D-Planes Compatibility. In the dialog, select the temp_2D.xml file of the subtitle stream, and the project directory containing the 3D-Planes (such as "...\Movie title\00000"). The tool will create a log file similar to this: Quote:
In the other 3D-Planes, look at the numbers of subtitles with totally undefined depth, subtitles with partially undefined depth, and subtitle frames with undefined depths. The lower the best. Therefore, the 3D-Planes #4 and #7 seem to be the best for the subtitle stream that has been analysed. They are good bets. In fact, with this BD, the French subtitles use the 3D-Plane #4. It has good values. As you can see, there is no perfect way to determine the correct 3D-Plane, but the tool can help you in finding a good one. Now, if the "good" 3D-Plane is not the one you have selected when you have generated the project, you can simply convert the 2D XML/PNG stream to 3D again with Subtitle tools -> Convert Subtitles to 3D, and of course use the new 3D-Plane. You can overwrite the original 3D SUP (or SUB) file created by BD3D2MK3D, or save the new subtitle under a different name and modify the filename of the streams in the __MUX_3D_OPTIONS.txt file. Finally, launch the encoding of the final SBS or T&B file, and verify carefully the subtitles. It they look wrong, try with another stream. You don't need to re-encode the video (unless you hardcode the subtitles on the video). Just use the __MUX.3D.cmd to re-create the final MKV with the new 3D subtitles. Good luck!

Thank You.
When i load a BD with BD3D2MK3D i see a list of how you described. In my Case the AVC Stream is also left, now i unsterstand. But what you've written about the 3D-Planes sounds very complicated. Is all this also important if i only used forced subtitles? |

Yes, it's important too. The correct depths of the individual subtitles depend of the 3D-Plane, and if you select a wrong 3D-Plane, you may have some subtitles entering within the foreground objects. It's terrible for the brain! Of course, if there are only a few forced subtitles, the risk of bad depths is less important, but that doesn't mean that you can ignore it.
Don't worry. The method to determine a correct 3D-Plane looks complicated, but it is not. The Verify 3D-Planes Compatibility tool can be used to verify if the 3D-Plane you have selected in tab 2 was correct or totally wrong. In the second case, you can find a good one easily with the tool, and convert the 2D stream to 3D manually. That's really not difficult. Try to do it, and you'll see.

I'm working on the processing of the audio by BD3D2MK3D (to allow the user to convert the AC3, THD and EAC3 streams to AAC too), and I verify if it works correctly in MKV-3D input mode too. And I have a problem !
I use a short movie with an E-AC3 (DD+) track to do my tests. When I demux the E-AC3 track from the BD with tsMuxeR or eac3to (without the option to keep only the core), I get a file of 19,961 KB. When I retrieve only the core, the file size is 11,406 KB. MediaInfo recognises the files correctly as AC3+ or AC3. So far so good. But when I convert the movie to 3D-MKV with MakeMKV and I ask to keep the whole AC3+ file and the AC3 core, it creates two streams in the MKV container: the AC3+ and the AC3. That seems correct. But when the AC3+ stream is extracted with tsMuxeR (without the core option), its size is only 8,555 KB. (The size of the AC3 stream is correctly 11,406 KB.) And MediaInfo doesn't recognise the AC3+ stream it at all. It prints only its file size. Demuxing the same stream from the 3D-MKV with eac3to gives the same result, but it prints an error message: Code:
MKV, 1 video track, 5 audio tracks, 0:03:02, 24p /1.001 1: h264/MVC (right eye), English, 1080p24 /1.001 (16:9) 2: TrueHD, English, 7.1 channels, 48kHz "Surround 7.1" 3: AC3, English, 5.1 channels, 640kbps, 48kHz "Surround 5.1" 4: AC3 Surround, English, 2.0 channels, 320kbps, 48kHz "Stereo" 5: EAC3, French, 2/2 channels, 48kHz "Surround 4.0" 6: AC3, French, 5.1 channels, 512kbps, 48kHz "Surround 5.1" Bitstream parsing for track 5 failed. Demuxing this track may still produce correct results - or not. a05 Extracting audio track number 5... a05 Creating file "test.eac3"... Video track 1 contains 4375 frames. eac3to processing took 6 seconds. Done. I don't understand why it does that. Does it make sense to store the AC3+ stream without its core? AFAIK, the "+" extension cannot be decoded without the core. Correct? Is it a known bug of MakeMKV ? If it's the case, should BD3D2MK3D prohibit to use the AC3+ streams from a 3D-MKV container created by MakeMKV ? Or should we report that bug to the MakeMKV staff ? Thanks in advance if someone can help me understand that mess!

I tried my luck and opened a 3D-BD in BD3D2MK3D to see which Stream i must select. The encoding is completed without an error after 3 hours but the merged MKV File is only 5GB large. This can't be right or?
The MKV File from makeMKV is 30GB large. Where ist the mistake? Last edited by Triple-M; 10th April 2016 at 15:10. |

MakeMKV only copies the streams from the BluRay. BD3D2MK3D re-compresses the MVC stream to a different format so the file size can change dramatically. You cannot convert from MVC to Side by Side or Top & Bottom without re-encoding. If you think the resulting quality is too low for your taste you can decrease the CRF value. Then the files will come out bigger and with better quality.

Ok, i thought thats the encoder option which ist not right but what kind of attitude ist right for the best video quality? CRF 0? Or CQ, 2-pass or ABR?
Like I said I want the best possible quality, equal to the Bitrate of the BD or the 3D-MKV File from makeMKV. Last edited by Triple-M; 10th April 2016 at 15:32. |

CRF is usually recommended. The lower the CRF value the better the quality and the bigger the file. But at some point there are diminishing returns. The file could become even bigger than the original BluRay! Most people on here seem to use a value between 16 and 20.

Yep. I use CRF 18 for the movies where the video quality is very important (like Sin City 2), and CRF 22 when I just want to keep a movie but I want the smallest file size. The default, CRF 23, gives already very good results.
Note also that the CRF mode gives very different file sizes for movies of the same length. For example, CRF 20 may produce a very small file of only 2 or 3 GB if the movie is very easy to compress, like a CGI (Pixar) movie. In the other hand, an old movie with much noise may require 10 GB for the same movie duration. It's absolutely normal, and it's one of the major advantages of the CRF mode over 1 and 2-pass. The quality is maintained in all cases, regardless of the difficulty to compress the movie. (It's different if you use 1 or 2-pass encoding, where the bitrate is specified. And anyway, 2-pass gives always a slightly lower quality than CRF for the same file size.) The CRF value is not all. You can compress even better without quality loss if you select a slower preset. I use normally the slow or slower preset, to keep a very good quality with a small file size. And don't forget that in the original BD, two full-size video streams are encoded. In Half-SBS or Half-T&B, the resolution is divided by 2 and therefore the resulting movie requires much less disc space anyway. Finally, don't be scared by the final size. It may appear too small, but x264 is an excellent encoder, and IMO, the large bitrates used for the commercial BDs are mainly to impress the consumer, and justify the high price for a double-layer BD 50. IMO, it's usually not necessary. Trust your eyes, and watch the small movies encoded with a relatively high CRF without prejudice. I bet that you will not see the difference with the original BD.

Thanks both of you.
I finished my first File and compared it with the original BD. In my opinion the 3D-Effect of the new encoded MKV-File ist much better as directly from the BD! This is great! Is there an option in the Settings or so that my TV recognized automatically the 3D-Signal and switch on 3D-Mode? My MediaPlayer is AppleTV 4.... |

If nothing works, consult the Apple TV manual, and if there is a special file extension not already implemented in BD3D2MK3D, I'll add it. Otherwise, ask Apple to do a better job!

Yep. It's also what I've noticed. Pity. And thanks for the info.

BD3D2MK3D v0.88
As promised, it is now possible to convert any audio stream to AAC.
I have also verified the conversion when using a 3D-MKV file created by MakeMKV as input, and unfortunately I have had to prohibit to use the E-AC3/DD+ streams with 4 channels only. They are bad conversion by MakeMKV, totally unusable. Luckily, the E-AC3 format is rarely used on the commercial BDs, but if you have a movie with DD+ streams, you will have to select the AC3 core in the MakeMKV GUI. When that huge bug will be fixed in MakeMKV, BD3D2MK3D should accept the E-AC3 tracks (with 7.1 channels) without problem. Please note that when using a 3D MKV as input, it is not possible to convert or extract the core of the TrueHD audio tracks, because the THD stream is stored "alone", without a 5.1 pseudo-core in the MKV. (It's a Matroska requirement.) Therefore, there is nothing to extract. It is not possible either to convert the THD track to AC3, simply because it doesn't make much sense to convert the THD track when the AC3 track is available without conversion in the original BD. If you want to keep the AC3 track, you have to select it in the MakeMKV GUI. (Of course, you can also convert the THD track manually with the Tool menu or with eac3to, but that's another story.) There are also two important bugs fixed in the tool to convert a SRT subtitle file to ASS 3D. Quote:
