I have ripped my entire film collection to MKVs and am now turning my attention to my 3D films. I cannot find the answer to this question at all, on here or anywhere. I am ripping using a combination of pavtubeByteCopy and DVDFab. The former mainly for TV shows and the latter for everything else. My problem is how do I identify which title(s) on the disc are the 3D ones? I have MKVToolNix, which I am planning on using to identify subtitles to force, but that won’t (I think) help before the rip. I have tried VLC but that seems to work on DVDs only. MovieScanner is similarly unhelpful. Does anyone have a suggestion for some code or string in each title’s info or ANYTHING I can use to identify which titles play in 3D???
Once I can do that I can then research how best to rip these films.
There is no automatic method for analyzing a video stream without a lot of CPU processing time, to determine if there are multiple complete images in the video stream.
Certain Plex clients are sensitive to -ou and -sbs tagging of the file name (Samsung is one). When these names are spotted by the client player, it will automatically put the TV into '3D mode".
VLC is able to read the raw media and see the media’s 3D tagging. If ripping software (universally) were to identify such flags, I have no doubt PMS would have support for it but at present it doesn’t. Does this make sense?

In the interim, what I have done is create a PMS Library that contains only 3D content.
This is what I have done for my 3D content as well. I am using TAB/SBS for 3D as Plex can’t play frame-sequential 3D, but I still can’t get my TV to automatically switch into 3D mode.
When you sue DVDFab are you ripping to TAB/SBS or some other 3D format?
Thanks for the quick replies. Only ChuckPa (I think) gets anywhere close to the answer! I think he says “No”. To be clear, I am not asking about ripping settings (although see below), filing systems or auto-3D sensing. I am asking if, when I put the disc in my Mac, is there any way I can tell which of the possible titles are the 3D ones? To my mind there must be something in tags/metadata/info that indicates if it will be played in 3D. The reason is that I cannot tell which title is being played off the disc by my 3D player so I can’t tell which to rip. Some discs offer a selection of titles and picking the right one is a complete guess.
By the way, thank you jjrjr1 for the thumbs up for DVDFab’s 3D ripping. What I need to do is to experiment with the various settings as I guess that everyone’s TV and Plex client settings will be different. If that’s not so, do you know what works best for a Sony Bravia TV and Samsung client???
In case it helps, further clarification: this is for those instance when the 2D and 3D versions are on the same BD. When two discs are provided which is which is blistering obvious! I’ve attached the Resident Evil listing in DVDFab. It contains both 2D and 3D films but I have eight titles from which to choose. Using things like number of subtitles or audio tracks doesn’t give any likely candidates as they’re all the same.
It’s almost certainly one of the ones which says “left”, as 3D Titles contain a “left eye” video track and a “right eye” differential video track building that image from. Multiple titles like that are often a case of either different versions of a movie (e.g. Theatrical vs. Director’s Cut) or multiple languages where the visuals are changed for each version (this is especially common for Pixar films as they re-do all the language-specific visuals so the movie looks native in most languages). Lastly, some movies will have some sort of picture-in-picture thing like a visually-active commentary, and these will be separate titles.
In all cases these are built as the sum of m2ts files, and the listing of what m2ts files are used can be pulled with some tools; you can then open/analyze individual m2ts files which are unique to each title to suss out what’s going on.
Thank you univbee - that would narrow down my choices quite considerably. However, the first “left” title in my screen shot is the one I have ripped as 2D and it seems happy as that in my player! Any idea what m2ts tools I could use?
