A MK3D file is already a 3D movie (more precisely, a MKV file with 3D content). Why do you want to convert it again ?
However, if your MKV file is a file containing the original AVC and MVC video streams, copied without re-encoding by MakeMKV, then you can use BD3D2MK3D (in MKV input mode) to create a SBS. But normally, that kind of 3D MKV has the regular .mkv file extension, not .mk3d. If you need more help, tell me exactly what is inside your mk3d file.

Thank you for your reply. I need to convert it because I don't know how else to play it on my older LG 3D TV. I tried BD3D2MK3D, it tells me that my file does not contain the streams it wants (no MVC). Here is what MediaInfo says:

I see in the MediaInfo log: MultiView_Layout : Both Eyes laced in one block (left eye first). It's probably the frame sequential 3D format (FS for short). Unfortunately, it's a format that can be created by BD3D2MK3D, but not opened. There is little sense in converting a 3D movie to FS, then again from FS to SBS. It's two time a lossy conversion.
Your FS version is big: 36.9 GB ! That means that the quality of the video is probably high, but it is difficult to convert it again, as FS is a final 3D format to be played with some specific players (mainly projectors), not a format intended to be converted. Anyway, BD3D2MK3D cannot help. I suggest to convert your movie from the original BD directly to SBS with BD3D2MK3D. You can use MakeMKV to create a AVC+MVC 3D MKV that you will probably be unable to play, but that can be opened by BD3D2MK3D. It is theoretically also possible to convert your MKV to SBS, but that require a good knowledge of the Avisynth scripting, and you will need also a few other programs. Honestly, I can't explain how to do it without your MKV file.

VideoHelp to the rescue: https://forum.videohelp.com/threads/...ide-by-side-3D
Except AviSynth thinks the video has half the frames, so the approach suggested there does not work, it just picks every other frame instead of the left/right frames. Last edited by ai4spam; 23rd October 2019 at 16:15. |

I don't understand. IMO, the script in the second post is correct (assuming your movie is really encoded in FS format). Here it is, with some comments:
Code:
WhateverSource() # I would use: FFMpegSource2("movie.mkv") left=SelectEven().BilinearResize(width/2,height) # This select only half the frames, normally the frames for the left eye, and resize them right=SelectOdd().BilinearResize(width/2,height) # This select only half the frames, normally the frames for the right eye, and resize them StackHorizontal(left,right) # Creates the SBS by concatenating the left and right frames, and returns the resulting movie And to create the x264 stream from it, you can use Simple x264 Launcher. And use mkvtoolnix for the MKV.

Well, the problem with that script is that AviSynth (and VirtualDub2, for example) don't actually show double the number of frames, so that choosing the even and odd frames would be getting the left and right views. Instead, it only gets the left view frames, and has no idea how to get the right view frames.
There seems to be talk about ssifSource2 and h264stereosource as AviSynth plugins, but no reputable sources to get them or instructions how to use them. |

The important part seems to be: Code:
Format profile : Stereo High@L4.1 / High@L4.1 MultiView_Count : 2 Code:

The count of 2 views is obviously always 2 for stereo and doesn't inform of the packing format. So, this tells us only that the two views have been encoded separately. That can be AVC+MVC or Frame Sequential. Quote:
I can only trust ai4spam: So, it must be FS, no ?

I don;t know (or remember) how h264stereosource works.

It say "Stereo High".

Either way MediaInfo notation does not always follow exact wording from the specs so discussion about that is moot. |

The problem is that, as far as I know, the stereoscopic MKV files with AVC+MVC can only be produced by MakeMKV. And that files can easily be opened bu BD3D2MK3D. Therefore, it MUST be something else. I don't know what, but I suspect some kind of frame sequential (aka frame-alternate) packing. And for that packing, the Avisynth script above should work. So, I don't understand why the two methods fail.
