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

[badtux]

bonjour desole pour mon anglais qui est traduit par google.
Je viens de tester la version 1.35 et j,ai un probléme que je n'avais pas avec la version 1.33 que j'utilisé .
Voici le message que j'ai dans encode3d.cmd
"error: ERROR: Cannot initialize Intel Media SDK session.

(__ENCODE_3D_MOVIE.avs, line 50)
x265 [error]: unable to open input file <->
Encoding finished 13/01/2025 20:57:14,70 "

pourriez vous m'indiquez la marche a suivre pour contenir ce probléme ?

Merci .

Hello sorry for my English which is translated by Google. I just tested version 1.35 and I have a problem that I didn't have with the version 1.33 that I used. Here is the message I have in encode3d.cmd
"error: ERROR: Cannot initialize Intel Media SDK session.

(__ENCODE_3D_MOVIE.avs, line 50)
x265 [error]: unable to open input file <->
Encoding finished 13/01/2025 20:57:14,70 "

Could you tell me how to contain this problem? Thank you.

Le français, ça me va (mais pas trop, le forun doit être en anglais ! )
English translation below

C'est curieux car rien n'a changé dans BD3D2MK3D avec le SDK d'Intel. Mais peut-être que la librairie d'Intel a été mise à jour sur ton PC et qu'elle déconne ? Essayes d'utiliser la librairie software, fournie avec BD3D2MK3D: Settings -> MVC Decoder -> Hardware Acceleration -> Disabled

Tu peux aussi modifier le projet sans le régénérer. Voir ici, dernier paragraphe (en anglais)

Curious, as nothing has changed in BD3D2MK3D with the Intel SDK. But perhaps the Intel library has been updated in your PC, and it doesn't work correctly. Try to use the software library, provided with BD3D2MK3D: Settings -> MVC Decoder -> Hardware Acceleration -> Disabled

You can also modify the project without regenerating it. See here, last paragraph.

Hello
I had to delete the archive and download it again. The archive must have had a bug. It works properly again. I thank you for this great software which for me who has a PC not powerful enough to use anything else, works perfectly.

[r0lZ]

Thanks for your positive appréciation and the confirmation.
For the archive, I suppose that the problem was caused by a glitch during the download, as I have not re-uploaded it recently. Anyway, if it works now, it's perfect.
Bon plaisir avec BD3D2MK3D !

Hi there r0lZ

My question is, how can I rip a 3DBD turned into ISO preserving the 3D subs depth to mkv? I've tried using Subtitles types: 3D only. and Blu-ray SUP format. The resulting subs are ripped like typical IDX 2D subs with no depth whatsoever (they render at screen depth). Also I can see in the Generating project Window that the subs are converted with the .2D suffix. I'd appreciate a bit of knowledge on the matter. Thanks again!

[r0lZ]

Hum, strange. If you have converted the subtitles to 3D, you should obtain 3D subs! The 3D subs are doubled, with 2 times the same subtitle side by side (for half-SBS).

Of course, the depth is correct only if the original BD has correct 3D subs, with good "3D planes". It is also necessary to watch the movie with a player that can display the 3D subs correctly.

Also, unfortunately, due to a limitation of the size of the subtitles, it is not possible to create 3D subs for Full-SBS or Full-TAB.

To avoid all possible problems, I suggest to "hardcode" the subtitles on the image (See the last tab). You will have the guarantee that the subtitles are properly displayed, including in Full-SBS/TAB. The price to pay is that you will not be able to disable the subtitles, or to keep several subtitles streams for the same movie.

Also, unfortunately, due to a limitation of the size of the subtitles, it is not possible to create 3D subs for Full-SBS or Full-TAB.

I see! So that's why they're converting with the .2D suffix since I'm turning into Full-SBS... I guess there's no way to extract the subs (and only the subs) in 3D from the resulting ISO and muxing them afterwards in a Full-SBS/TaB file?

[r0lZ]

The subtitles in a 3D BD are always in 2D. But the BD contains the so called "3D planes" or "offset sequences" that instruct the player of the offset (horizontal displacement) to apply to the left and right subtitles to display then with the correct depth.

Since, when the BD is converted to SBS MKV, the offset sequences are lost, BD3D2MK3D converts the subtitles to 3D. It copies each subtitle image twice, taking into account the offset sequence, so that it obtains something like a SBS subtitle. The player must then display it over the SBS video BEFORE it splits the two images to send them to the left and right eyes (hence the problem with many players only able to display 2D subtitles AFTER the split).

The problem with Full-SBS is that the SBS subtitle must be larger than a full-HD picture, and that's prohibited and currently not possible (even for UHD/4K video, where the subtitles are only in full-HD resolution and must be resized in real time by the player).

It's why I suggest to hardcode the 3D subtitles in Full-SBS. In that case, the two subtitles are processed separately and encoded on the left and right images respectively before the two images are sticked together to form the final SBS view. The player has therefore to process only a Full-SBS image, without ever knowing that there are subtitles. Currently, it's the only good solution for Full-SBS.

Currently, it's the only good solution for Full-SBS.

Understood, thanks for your time r0lZ.

Hello,
Can someone please tell me the settings for using CUDA/NVenc for x256?
Or can I use an external converter like ffmpeg? I would know the parameters there.

[r0lZ]

It is not possible to use CUDA with x265 (and with x264).

But you can use an external encoder. Enable Settings -> AVC/HEVC Encoder -> Use your own custom command for encoding. The last tab will change to allow you to type your own command. Don't forget to save your settings if you don't want to type it again next time. Use the 3 Help buttons to learn how to use the predefined variables.

As an example, here is a NVenc command that works fine to encode in AVC format:

"path\\to\\nvencc64.exe" ^\n --codec avc --cqp 26 --profile high --level 4.1 --preset quality --sar ${sar} ^\n --colorprim bt709 --colorrange limited --chapter chapters_3D_delay.ogm.txt --key-on-chapter ^\n --input "__ENCODE_3D_MOVIE.avs" --output "video3D_nvenc.avc"
With that command, you have to specify video3D_nvenc.avc within the Filename of video stream field.

Note that encoding with a CUDA powered encoder gives always a less good quality than with x264 or x265.

[DjEKI]

Thanks for the settings. So far, I'm very happy with the settings. In "video3D_nvenc.mp4," I have an aspect ratio of 0.889. That's exactly what I need. But in the MKV, it's suddenly 16:9. How can I change that to 0.889? The video absolutely has to be a full 1920x1080. Because of the full top/down video, it's a total of 1920x2160, which is what I need. Including the black bars. However, everything is wrong again in the MKV file.

"E:\\3D Filme\\BD3D2MK3D\\NVEnc\\NVEncC64.exe" ^\n --codec hevc --vbr 7500 ^\n --chapter chapters_3D_delay.ogm.txt --key-on-chapter ^\n --input "__ENCODE_3D_MOVIE.avs" --output "video3D_nvenc.mp4"

[r0lZ]

See the long discussion about the aspect ratio in full-SBS or full-TAB here.

Or, in short, look at the Settings menu.

Hello!

I have a weird issue where output Full SBS 3D movies don't display correctly without having to change the aspect ratio in the player, unless transcoded or re-encoded through handbrake first.

Seems like something BD3D2MK3D should be able to handle, without requiring an extra steps, considering it encodes the 3D movie in h264 just like handbrake.

I leave everything as default except for unchecking the "Half" checkbox.

What setting am I missing?

[r0lZ]

Look at my last post, just above yours.

[alexbgames]

Look at my last post, just above yours.

Unfortunately, that's not the solution. Using "Use respectively 32:9 or 16:18...", just creates a problem on the other end.

It displays correctly when direct playing but doesn't when transcoded.

I need it to display correctly in both cases, direct play and transcoded, like it does when I take the output of BD3D2MK3D with the aspect ratio set to "Use 16:9 AR...." and run it through handbrake.

I'd like to eliminate having to run it through handbrake if possible.

[r0lZ]

Have you also tried changing the SAR?

Anyway, with these two settings, you have everything related to the aspect ratio. I can't do more.

It displays correctly when direct playing but doesn't when transcoded.

IMO, that means that it's the transcoding operation that is the culprit. BD3D2MK3D is not responsible for what other softwares do.
