  1. Hi, everyone!

    I want to convert a 2D PGS subtitle to a 3D HalfSBS subtitle without OCR, keeping the original subs as they are.

    I have a movie (in this case, disney's "The Little Mermaid") in both 2D and 3D. A 3D Blu-Ray featuring my language does not exist, as we never got the 3D version, but we do have a nice 2D version that does. So I bought both versions, thinking I'd take the audio and subtitles in my language from our local 2D release and add them to the 3D version.

    I ripped both versions with DVDFab, and encoded the 3D one to HalfSBS. As expected, everything synced perfectly right away. But...

    I want to maintain the styling of the subtitles, meaning I don't want to OCR them and use 3DSubtitler after. I just want to convert a 2D PGS to a 3D HalfSBS PGS.

    First, I tried ripping the 3D version without selecting 3D options in DVDFab, muxing the PGS in the result, and encode it to HalfSBS. It worked, but the subs were turned into VobSub. The option to choose VobSub or PGS subs wasn't present in DVDFab during encoding from this "remux". 11 Hours wasted lol.

    Then I found out about a tool called "Suppe3D.exe". It supposedly does what I need, but I can't find a download anywhere anymore.

    Then I tried BD3D2MK3D with the remuxed file from my first attempt, but it smells my file does not come from MakeMKV. I started suspecting DVDFab ditches the MVS during copying at this point.

    Then, I tried ripping the 2D version with 3D settings in DVDFab, hoping to extract the subs from the result and adding them to my HalfSBS encode. It again took 11 hours (even with CRF 30 and all settings on "Fast"), but it actually worked! Yay! The subs do appear a little low, but using BDSup2Sub, this can easily be fixed.

    I do, however, find 11 hours a incredibly long time to spend on just getting your subs right. Isn't there a easier and faster way to do this? Maybe preventing the need to reposition the subs?

  2. Hi, I'm the author of BD3D2MK3D.

    Normally, you have everything you need with BD3D2MK3D. And, as far as I know, it's the only software able to convert a 3D movie to SBS or TAB and preserve the original depth of the subtitles. (All other converters put the subtitles on the surface of the screen, and it's a terrible experience for the brain!)

    BD3D2MK3D requires as input an unencrypted ISO or a MKV created by MakeMKV with the original AVC and MVC video streams untouched. For the ISO input, you have to rip the BD to an unencrypted ISO first (for example with DVDFab HD Decrypter) or use an on the fly decrypting tool like AnyDVD HD. For the MakeMKV input, you should use MakeMKV (free while in beta with the key available here) to create a MKV with all audio and subtitle streams you need, plus the MVC video stream (disabled by default). Any other way to create a MKV is not compatible with BD3D2MK3D, as you will lose the important information from the MVC stream.

    Normally, BD3D2MK3D creates the final MKV automatically. However, it is easy to import an additional audio or subtitle stream, with some knowledge.

    To import your subtitle stream in 3D, you should generate the project with the 3DBD, and include at least one subtitle streams available in the 3DBD (with the option to convert it to 3D ticked in tab 2). I call that stream the "source stream" or "guide". It will be used later to position your subtitles correctly. For best results, select a language that ressembles your language.

    When the project is ready, extract the subtitle stream you need from the 2D BD, and convert it to 3D with Subtitles Tools -> Convert Subtitle to 3D (with 3D-Plane/OFS). You have to select the 3D-plane associated with the source subtitle stream. (See the end of the 3D-Planes.log file to see what stream is associated with what OFS file.) You may also have to use the "temp_2D.xml" file generated by BD3D2MK3D in the folder of the source subtitle stream as a guide for the subtitle positions on screen, if some source subtitles are placed at different positions on screen (for example, at the top of the screen, or to the left or right, to avoid entering in the foremost objects.) If you carefully select the right options, you should obtain a perfect (or almost perfect) 3D subtitle stream, with the right depth for each subtitle.

    When the conversion is finished, edit the file "__MUX_3D_OPTIONS.json" to replace the original subtitle stream with yours. You should change the track name, the language code and of course the file name, at the end of the section. (You may also need to change the --sync option if you need to resync the subtitles, but usually it's not necessary.) Note that BD3D2MK3D can keep the 3D and 2D versions of the subtitle stream (depending of the options selected in tab 2). If you kept the 2D version, you should edit the 2D subtitle too.

    Finally, launch __ENCODE_3D_LAUNCHER.cmd to generate the final MKV file, and everything should be fine.

    Note that you need a player that can display the 3D subtitles correctly. It's rarely the case with the hardware players, like most 3D TVs. If you cannot display the 3D subtitles correctly, I suggest to use the option to hardcode the 3D subtitles in the final image (in the last tab of BD3D2MK3D). The procedure is similar, but instead of modifying the file __MUX_3D_OPTIONS.json, you should edit the file __ENCODE_3D_MOVIE.avs, and simply replace the file name of the subtitle stream in the line beginning with SupTitle(.

    Good luck, and feel free to ask more info if necessary...

  3. Thanks! Just using Subtitles Tools -> Convert Subtitle to 3D did the trick for me. I left the 3D plane field open. The subtitle placement was correct right away.

    Is it still necessary to follow the other steps? All Disney 3D BD's (including Marvel ones) I've encountered so far didn't have any depth, as far as I could see. Also, I think the number of subtitle lines might be different. Is this a problem?

  4. Well, if you did not use the 3D-plane, the subtitles cannot have the right depths. And I'm sure all Disney/Marvel releases have (good) 3D-Planes, with the correct depth for each subtitle. Only cheap and Asian movies (or the ISOs re-encoded for a BD25 usually found on the internet) have usually no depth or simply a fixed depth that is not suitable for all subtitles in the stream. Major US movies are always authored correctly.

    The placement of your stream can be correct in X and Y, but wrong in Z (the depth). So, if you want good results, you have to follow the instructions above. Or, if you can manage to extract the MVC video stream from your 3D-BD, you can simply extract the 3D-Planes from that stream with the command-line tool MVCPlanes2OFS.exe (available in the "toolset" folder of BD3D2MK3D) and use one of them to convert your subtitles.

    Of course, when the subtitle stream has been correctly converted to 3D, you do not need to encode the movie with BD3D2MK3D. You can just mux it with your video file already converted to SBS. The method I've explained above is more time consuming, but almost totally automatic, and IMO simpler. And as an additional benefit, you will encode your movie with x264, a MUCH better encoder than most commercial encoders.

    Of course, if you are happy with the subtitles entering in the foreground objects, it's up to you. Personally, I cannot support that !

  5. Maybe Holland gets bad releases? I saw some headache inducing stuff on Civil War, for instance. Subtitles don't even move out of the way when disturbing 3D, like moving to the top, or the side of the screen or something.

    Anyway, I will try re-encoding with your tool, then, following the steps. Truth be told, I didn't like encoding with DVDFab one bit anyway, but at the time, I didn't know of any other tool that could encode to (Half)SBS. I usually use ffmpeg (which is similar to x264, I think?) and that worked for me for years. I was especially frustrated about DVDFab lacking a option to set quality/speed options, which I prefer at veryslow. Fortunately, your tool has it. If this works out (and I assume it does), I have a new favourite HalfSBS encoding tool.

    After that I've found out how to encode to HalfSBS with ffmpeg, but it would require me to first figure out which eye is the standard one, then set the appropriate options. Your tool is probably a lot simpeler.

    Thanks for everything! You're my hero this week.

    But you forgot to answer one question: Is it a problem if the number of subtitle lines in the 2D and 3D subs are different? Or does it grab the depth from the video.

  6. Oh, and one other question, can your tool also open BD Folders? Haven't succeeded in that except by mounting the folder as an ISO using another tool and open that.

    No big problem, as it works, but maybe I'm just doing something wrong. Your tool does say "open ISO or Folder" so I thought I'd ask.

  7. I don't think that Disney produces badly authored 3D BDs anywhere in the world. I lives in Belgium, and most releases are made for the whole Benelux. As I wrote above, I have never seen a Disney 3DBD without 3D-Planes. And I love animation, so I did many Disney. Anyway, if you re-encode your movie with BD3D2MK3D, you will see a warning if a specific subtitle stream you have converted has no 3D-Plane, or if the 3D-Plane contains only undefined depth values. (There are more details in the 3D-Planes.log file.)

    The number of subtitles differ usually for different languages. The 3D-Plane contains the depth values for all frames in the movie, so it doesn't matter much if a stream has more or less subtitles than the guide. However, there are also frames with "undefined depth" in the 3D-Plane. Usually, they are only where there is no subtitle to display. If your stream has a subtitle in that frames, it will not have the correct depth, but luckily, it's relatively rare. However, when you have the choice, I suggest to not use the subtitles of the original language of the movie for the guide, as it doesn't translate the strings shown in the video (called "forced subtitles"). For example, the title of an English movie can be translated to your language, but since it is displayed on screen in English, there is of course no English subtitle to duplicate it, and there will probably be no depth values when the title appears. It's why it is preferable to use a language similar to yours for the guide, like Spanish for a French stream, where all forced subtitles are translated. The global number of characters in the translation may also be important, as it influences directly the width of the subtitles, and wider subtitles may not perfectly fit between the foreground objects. Choosing a more verbose language for the guide may therefore give better results.

    BD3D2MK3D can open BD folders, yes, but I strongly suggest to create only an ISO, as ripping to a folder will create two times all video files for all 3D content, and that will be long and consume much disc space. It's due to the specific 3D format, with a file for the 2D content, and one for the 3D. Both are merged together within a third file, virtual on the BD, but that will (probably) be created in the folder, hence doubling the file size. Also, ripping to an ISO is usually faster and safer.

    Or you can use the MakeMKV method. Since you need to process only the main movie (without the menus and bonus) and the audio and subtitle streams you really need, it's certainly the most rapid method, and it requires less disc space. Just don't forget to tick the MVC stream, or you will rip only the 2D version of the movie. It might also be a good idea to tick the JPEG picture at the end of the stream list if you want it as the icon for your 3D MKV file.

  8. I already knew about the foreign language for the "guide" subtitle as you call it thing, but thanks anyway. The standard subs tend to be subs for the hearing impaired with some movies, so I'm well aware. Not sure if it's possible in this case, but nevermind. The only forced subtitle in this case is the movie title anyway. And in this case, the background at that moment is far in the back, so there shouldn't be any problems there.

    I prefer ISO too, but I have some Folders ripped that won't convert to iso. Guess I'll have to re-rip them to ISO directly. Or use the mounting method and delete the folders after. It's mainly just so my daughters and sister can enjoy the movie in 3D, as they don't speak English (fully) yet. They probably don't care about the extras anyway. The ISO/folder is only for ripping/encoding.

    Oh, and one last question. On the rightmost tab on your tool where you select the SBS/OU/FS stuff, it says "left view always first". Does this just mean that the Left eye will become the left side of your SBS file, or does it mean that it always assume the left eye is standard view? Some BD's, like Jungle Book, for instance, have right eye as standard view.

    Thx for everything! Bedankt voor alles!

  9. The subs for the hearing impaired are usually good to use for the guide, because they are much numerous than the standard translation subs. The risk of undefined frames is therefore less important than with the standard stream (with perhaps the exception of some forced subs).

    The de-facto standard of the views order is left view to the left for SBS and on top for TAB. BD3D2MK3D is smart enough to extract the order of the view from the 3D BD (with, as far as I know, only one exception of a badly authored BD). It swaps the views automatically if it's necessary, to respect the de-facto standard. Therefore, the views of the final SBS video are normally always in the correct order. (The option Right View First in the dialog of the 3D conversion of the subtitles is useful only if you want to generate the 3D subs for a downloaded SBS/TAB with inverted views, like some shorts available on Youtube. It should never be used for a movie converted by BD3D2MK3D.)

  10. Thx again. Suspected as much. I still have one question, tho. Should really be the last one.

    There is an option to only use the core 5.1 audio of DTS-HD MA, TrueHD and E-AC3. Why is it HIGHLY RECOMMENDED to tick this box? I'd like to preserve the DTS-HD MA.
    Quote Quote  
  11. Oh, "highly" is perhaps too much! It is mainly there for historical reasons, as when I started to write BD3D2MK3D, most TVs were unable to play the HD tracks.

    The problem is that a DTS HD-MA track on the BD is in fact composed of two different tracks, merged together so that only one track is visible to the user. Many peoples think that their TV or audio equipment can play the HD-MA track, but in fact, only the 5.1 DTS track is really used. In a MKV container, it is not possible to keep the two merged tracks together, so you have to select only the DTS or the HD-MA sub-track. I recommend DTS for compatibility reasons, and also because it doesn't consume much disc size, but of course, if you know what you are doing, you can keep the HD-MA track. (Be sure to select the right track also in MakeMKV if you use that extraction method.)

    It's not the same thing with AC3/THD, where there is really a core and an extension, and things are usually better understood by the users. Again, you may prefer the quality over the file size. It's your choice.

  12. Not only does it say "highly", it's in caps even lol.

    I do prefer quality over file size. At least since I got my new hdd. I play my stuff usually through a Sony BD player or a modded PS3, both of which seem to accept DTS-HD MA just fine.

    But I'm pretty sure MKV can contain DTS-HDMA and only use what's necessary. I have created lots of MKV files that say "Master Audio / Core" and "8 / 6 channels" on mediainfo. They also work perfectly fine, even if 7.1 HDMA is played on a 5.1 set.

  13. Hum, strange. Perhaps things have changed. Thanks for the info. I will verify, and if necessary, modify BD3D2MK3D...
