Er...OK...this time I didn't understand everything (Full-TAB, AR, DAR) but I keep in mind what you suggest about the Settings -> Full SBS/T&B aspect ratio.

PS : I can't send you a private message : each time I write something and I click on "submit message", it's like it's working...but I don't see anything in "Sent item" so...I assume everything I wrote is lost...

Make sure "Save a copy of this message in your Sent Items folder" is ticked when you write a PM. You can activate this option by default in the Options of your CP.

I have received them, and replied. Maybe you have also to untick the "Receive Private Messages only from Contacts and Moderators" option ?

Just a few words in reply

When they play a 3D movie, they have to handle two views at the same time, and therefore, they cannot do it in full resolution.
Yes, I should have mentionned my post did not apply to all TVs indeed.

Agreed, FTAB/FSBS is mainly intended to get the best out of UHD TVs.

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.
Yes this is a bit strange and I just noticed this lately, however I have had that TV for nearly 3 years...
BTW "Your TV (and perhaps most or all LG TVs) has a problem with Full-TAB" ==> I guess you wanted to write "with Full-SBS".

May I give my 2 cents about how I sort the things out of this SAR/DAR complexity when I encode in FTAB (for my LG UHD TV) ?

After the 3D encoding, I use MKVToolNix with the header editor, and edit the "Video display width/height" of the video stream with the target 1920/1080 values (usually they are set to same values as "Video pixel width/height" of 1920/2160).

Maybe I could set the parameters right in BD3D2MK3D that would do it for me without tweaking, but I don't remember ever succeeding with this, and this header tweaking gives me a 100% assurance that everything will play fine on the TV.

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.

Well, just tick "Settings -> Full SBS/T&B Aspect Ratio -> Use 16:9 AR For Both (Not recommended)". That should put directly the right values for your TV in the MKV header.

Unfortunately, some TVs prefer to trust the SAR in the video stream, and AFAIK, you cannot change it without re-encoding.

ffmpeg can change H.264 and HEVC SAR values without re-encoding.

As explained by tebasuna51, when you use the CRF encoding mode, the quality doesn't vary much, but the file size can vary, due to the difficulty to compress the images of the original movie. A CGI film like an animated Pixar movie can be compressed extremely well, because the image is very clean and without artifacts. In the other hand, old movies with much noise are very difficult to compress, because each frame is different from the previous one. So, differences in file size are not unusual, and you should not worry about them.

BTW, many peoples think that a specific bitrate is important to encode correctly, and prefer to encode in 2-pass mode for that reason, but it's totally wrong. Specifying the bitrate (in ABR or even 2-pass modes) imposes a constraint that the encoder must obey, and therefore, the quality is ALWAYS less good than the encoding in CRF mode (when it gives finally approximately the same file size, of course). The ONLY interest of 2-pass mode is therefore to control precisely the size of the final MKV file. That may be important if you need to copy it on a physical media like a DVD, but you should always avoid that mode if you don't care of the final file size.

See also my previous reply, just above this one.

Thank you very much for your helpful response (and tebasuna51).

Just one more query please. At some point during the majority of my 3D conversions there is a green flash and the 3D is thrown out of synch. It's is pretty random and can happen once or multiple times, and usually there will be another green flash and the 3D will return to normal.

Do you know why this happens? I wondered if it was something to do with checking the laptop during the conversion process?

Thank you!

Could be a decoding problem. Are you using hardware decoding? Try turning it off.

Under v1.9 no problems.
Tested on 2 PC with 2 images.
I too got this error, went back to 1.9. Also wondering if any testing done with AVISynth+ http://avs-plus.net/

That may be caused by the laptop going to sleep. x264 (and probably also x265) do not like being interrupted.

Are you sure you launch __ENCODE_3D_LAUNCHER.cmd and not directly __ENCODE_3D.cmd ? Also, be sure to not set your laptop to sleep mode manually during an encoding.

Anyway, normally, you can have a look at the title bar of the command prompt window when you want to see the progress of the encoding. As long as you don't launch another heavy task at the same time, everything should be fine.

Try also to turn the hardware decoding off, as suggested by sneaker_ger.

Personally, I have never has that kind of problem.

Sorry, I have not much time currently. I'll fix that bug as soon as possible...

No, I'm personally not really interested in the numerous forks of avisynth. I prefer to stick to the good old bug free version. But if anisynth+ has the same syntax, you can try it yourself, simply by modifying the file name in __ENCODE_3D.cmd.

There are nothing to modify, I'm running Avs+ (32 and 64 versions installed) without problems.

Of course the 32 version is used with 32 bits plugins used in BD3D2MK3D.

I can make a test loading FRIMSource64.dll and encoding directly with x264_x64.exe, instead use the intermediate avs2yuv.exe, to see the speed change.

Interesting. Thanks for your test ! Maybe I'll implement some support for Avisynth+ 64-bit, but I have to verify first that all plugins necessary for BD3D2MK3D are available.

BD3D2MK3D v1.11

OK, I think the bug with the bitrate variable is now really fixed. Please confirm !
Quote:
v1.11 (August 28, 2019)
- Fix: Hopefully definitively fixed the bug of the uninitialized bitrate variable
- Updated BDSup2Sub++.exe to the latest version (1.0.3) and modified the link to the BDSup2Sub++ home in the Help menu
- Updated the Mkvtoolnix exes to the latest version (37.0.0 'Leave It')
Download: BD3D2MK3D.7z

Thanks for the new version.

All plugins (I think LoadHelper.dll is not used now, it is not needed at all) have 64 bits versions (all supported for Avs+):

DGMVCDecode.dll, libmfxsw.dll
FRIMSource.dll, libmfxsw.dll
SupCore.dll, SupTitle.dll
VSFilter.dll with a modern VSFilter.dll

Maybe you need these little tool from Groucho2004 to know if AviSynth 64 version is instaled, with both Avs+ (pool):
Quote:
AVSVersion32.exe
32 Bit: AviSynth+ 0.1 (r2772, MT, i386) (0.1.0.0)

AVSVersion64.exe
64 Bit: AviSynth+ 0.1 (r2772, MT, x86_64) (0.1.0.0)

Fine, thanks ! Indeed, it seems that the 64-bit version of Avisynth+ is stable. At least, it is used by a lot of peoples. I will therefore probably implement it, but that will take some time...

OK, I did some tests with Avisynth+ 32-bit, and everything seems to work correctly, without any modification. So, I guess that using the 64-bit version will not be much more difficult.
