OK, thanks. I will try to reproduce the bug. I have an idea, but I'm not sure...

I was right, and that bug was easy to reproduce.
The problem was due to the generation of the scripts necessary to encode the 2D version of the movie. (This feature is not widely used, but has been requested by some users, and it was relatively easy to implement, so I did it.) For technical reasons, it is not possible to encode the 2D version with x265. Therefore, to generate the script, the program uses the settings of the x264 encoder, set in the last tab when the selected encoder is x264. You can, for example, set it to encode in 2-pass. Then, you change your mind, and you select the x265 HEVC encoder. The settings in the last tab change, and can be, for example, CRF 28. Then you launch the generation of the project. It is correctly generated for the 3D version, but the bitrate variable, not necessary when encoding in CRF mode, is not properly initialized. Since the x264 encoding in 2-pass mode requires the bitrate variable, the program crashes when it generates the _ENCODE_2D.cmd script. Luckily, that bug had no impact on the 3D versions, and did not occur when the two encoding modes (for x264 and x265) were identical (CRF for example). Anyway, that bug is now fixed. I will release a new version soon...

I would also recommend introducing QSVEnc, VCEEnc and NVEnc, so that there are more choices.

The big work of BD3D2MK3D is prepare all files (avs, subs, etc.) to do the encode with __ENCODE_3D.cmd
If a user want try with other encoder is easy replace the x264/x265 line in that file with the equivalent for other encoder. I don't know QSVEnc or VCEEnc, with NVEnc I can make a equivalent command line encode except for --frame-packing 3 (basic for 3D output) but maybe any NVEnc expert can do it.

If I add a new encoder, it will certainly be NVEnc, as I suppose it is much faster than x264 or x265, for a slightly worse quality. But indeed, the lack of the equivalent of the --frame-packing argument is a problem.

Hi,
I converted my first movie yesterday successfully (BD3D2MK32 version 1.9 + AviSynth 2.6.0) Q1) I am just worried about these errors : Quote:
Q2 : if I understand correctly, "forced subtitles" are not very frequent. If I just care about the usual subtitles, what if the best choice to avoid complications? Radio button of my language + "default" radio button? Suggestion : why BD3D2MK32 is not able to keep my preferences on the output folders when it is restarted? |

Welcome to the Doom9 forums, thxoptimizer !
Quote:
As far as I know, the second error occurs only when there are severe errors in one or both video streams. That confirms probably that the ISO image is bad. The symptom is that the two views will be out of sync after a certain point. That can be a real torture for the brain ! But if you are extremely lucky, it's simply some frames missing in at the very end of one of the two video streams, and in that case (but in that case only), you don't have to worry. To verify, just play the very end of the movie in 3D, and see if both views are in sync. (It's easy to verify with the end credits sequence, when the text is moving up. Watch it without your 3D glasses. The text of the two views must appear "merged" at the same vertical position.) If the problem is confirmed, try to re-rip the BD, perhaps with another method. If the problem persists, that means that your BD is damaged, and there is probably nothing to do. Quote:
If there are two or more streams in your language, try to determine what is what with the preview (use a good player like PotPlayer). The first stream is usually the main stream, but the second can be either the forced stream, or a special stream like directors comments or for hearing impaired. If you are interested only in one subpic stream, it is sufficient to just select it. But if you select several streams, the Default radio-button can be used to force the subtitle to be the first available, and it sets also the "default" flag in the MKV header. That flag is supposed to instruct the player that it should enable that stream by default, but only a few players respect it. Anyway, it doesn't hurt to enable it. Also, to "avoid complications", it might be a good idea to encode the subtitles on the video, with the "Hardcode subtitles" option in the last tab. The advantage is that you will see the subtitles with the correct depth, regardless of the player you use. The drawback is, of course, that you need to choose only one stream, and that it will be impossible to turn it off during playback. So, use that option preferably when you want to watch the movie in its original language and with the subtitles anyway. Quote:
Note that the settings from the Settings menu (used less frequently) are saved immediately anyway.

Thanks for de new version.
Unfortunately I get the error message can't read "x264bitrate" with the version. Quote:

Reasons for Full-TAB over Full-SBS for 3D MKV encoding
Hi,
I did tests lately on my LG OLED E6 in order to check the differences or similarities between Full-SBS and Full-TAB. I have always encoded in FTAB, as I had the same logic ("it seems logical"), so just never tried FSBS until now. As I always encode in at least placebo/CRF15 quality with x264/8bit/BR compatible, I am quite confident the result is humanly indiscernable from the original BR (typically the resulting MKV file is nearly the same size as the original BR), and that my comparison tests are reliable. As a note, I do use "motion interpolation" option when watching in 3D in order to achieve the full immersive experience, but I don't think this messes up with the tests (high frame rate for 3D content really gives a much more dramatic improvement than for 2D content). Results: - image in FULL-TAB result is excellent, the 3D is crisp, with 100% certainty the 4K TV displays both full frames perfectly (e.g. alternate the 2x1080 lines over full 2160 height) - image in FULL-SBS is ok but NOT as good: it feels blurry, less defined, much more like "H-TAB" than "F-SBS". I tried to see if there was anything related to filters etc. but after many trials and settings tweaking, I couldn't achieve the same quality as FTAB. Altough it would require capturing the TV output and analyze it line by line to understand exactly what is happening, I'm quite confident that what is displayed is in fact H-TAB and that the TV does not make use of all the original video data. My 2 cents is that FTAB certainly allows for "simpler decoding" as you hinted, because the image being already encoded vertically, all the TV has to do is decode/split/interlace the lines "as is". In FSBS, there is much more work needed as lines have also to be moved around to arrange them vertically, and it is possible they just didn't care doing it for FSBS. Anyway, it might be a flaw with my particular TV model, but all in all, SBS seems a more complicated and risky option. In conclusion: choosing FTAB as a standard for encoding 3D MKVs seems the best option for maximum quality output on all equipments (as long as there are no problems related to FTAB on other TVs, but I have not seen any reports about such problems).

Also, I must admit that I don't understand why your TV shows the Full-SBS movies with less quality than Full-TAB. IMO, the two views must be cut BEFORE they are processed for the 3D display, and therefore, there is no reason to prefer one method over the other. But I trust your test. Your TV (and perhaps most or all LG TVs) has a problem with Full-TAB. That doesn't mean that the TVs made by other brands have the same problem. If would be nice to compare the two methods with, say, a Samsung UHD TV. I bet that both methods will give equivalent results. Anyway, BD3D2MK3D offers all possibilities, so you are free to use what gives the best result with your equipment.

Can you tell me exactly how you encode: x264 or x265 and with what mode (CRF, CQ, 2-pass or ABR) ? And if you encode with x265, please change the encoder and see what mode is selected for x264. I will have a look anyway...

@r0lZ : thank you for you very complete explanation.
1st movie (before your answer) : I have checked on my TV (LG 55C6V) and...I haven't found how to active the subtiles... I forgot to check the end of the movie as you said, nevermind it was just a 1st test. 2nd movie (after your answer) : I have followed all your recommendations and the subtitles ar directly visible. Unfortunately, I think my TV doesn't like Full SBS because what I see is a 3D movie with very large horizontal black bars For your information, usually I always watch my movies on physical support (Blu-Ray 3D), but I am just preparing when I will watch my movies on a headset because my next TV won't have 3D capability |

For a good result, you may have to change the AR settings with the menu Settings -> Full SBS/T&B aspect ratio. Note that there are two AR: the DAR set in the MKV header and the SAR in the video stream, so there is a total of 4 combinations. I suggest to encode a little clip several times just to verify what setting works for your TV. You can already exclude the default settings. :-( Note also that there is no problem in Half-SBS/TAB.
