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

[Ennio]

BD3D2MK3D v1.32 released

v1.32 (February 27, 2023)
- Fix: Wrong filenames when a multi-angle/multi-story MPLS is made of only 2 parts (for example Blade Runner 2049 French version)
- Added the menu Help -> MkvToolnix for Windows 7 to download easily a MkvToolnix version compatible with Windows 7 (Thanks Ennio!)
- Added a link to the mini-guide on how to convert an external SRT or SUB to 3D in the Subtitle Tools menu.
- Added a link to the Bernard's Wiki page about BD3D2MK3D in the Help menu. (Thanks Bernard!)

r0lZ, after putting proper win7 mkv.exe tools in the tools folder, there's still the popup with the win10 warning. It's of course no trouble to ignore, but maybe a popup is possible that will only alert when win7 tools aren't there or updates are available?

Why is the processing on the gpu less good? I would like to speed up the process. I have rtx40-series. The gpu's starting from 3000 series have powerful encoders/dencoders.

The authors of x264 and x265 do not want to add GPU support, because the quality is less good. I don't know exactly why, but I trust them. It's related to the parallel nature of the GPU processing. Anyway, there is no way to enable GPU encoding with these encoders.

However, if you really want to use a GPU powered encoder, you can use any command line encoder. You must install it and know how to use it. In BD3D2MK3D, select Settings -> AVC/HEVC Encoder -> Use your own custom command for encoding. The content of the last tab will change, and you will have to type the command you wish to use. For example, here is a command that use nvEnc with CUDA. I use it sometimes to do quick tests, but I am usually somewhat disappointed by the quality and the (relatively) slow speed.

"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"

Note that you can use variables (such as the ${sar} in the command above) so that your command will be automatically adapted to other conditions (such as HSBS vs FSBS). Note also the required double \\ in the paths.

Also, when your custom command works as expected, don't forget to use Settings -> Save Tabs Settings Now to force BD3D2MK3D to remember your custom command for the next time.

I have tried to do exactly that, but unfortunately, the special Win7 builds of mkvtoolnix have exactly the same version string than the official, Win10+ release. So, I have no way to know what version is installed. Hence the warning.
