[Feature request] convert 3D to 2D

Hello,

 

It would be very useful if plex server (reencoding) or client would be able to display 3D movie (top/bottom or side by side) even on 2D screen (displaying only half of the source.

It is very important as tablet can not display 3D content but i have 3D movies as sources for my TV.

It would be also useful for the people who connect to my server but don't have 3D tv

Not even sure if this is technically possible. But hypothetically if it were possible, it would probably be quite resource intensive. That begs the question of whether your Plex server will be capable of handling such a task. Remember, not everyone has a dedicated Plex server running a Core i7 CPU and 16GB of RAM. The QNAP NAS units and other similar devices would probably struggle to convert the video and perform whatever transcoding is required. These days hard drive space is affordable enough to have the same movie in standard and 3D.

This would probably not be much more CPU intensive than any other transcoding since it could be done just by using a crop filter and changing aspect ratio. Both are features supported by the Plex transcoder.

The difficult part is most probably writing the code and integrating the feature, especially considering how many Plex clients are available.

I believe this request should be supported

I had a low cost tablet able to do that. In fact it is not ressource consuming as you only have to crop half the picture and not make any difficult calculation.

You can force the user to select the 3D type but it could be even very easy very much CPU usage to automatically detect the format.

EDIT: already answered before :) Next time i will read all the post before sending answer... especially when there are only 2 posts  

there is an other thread that gives an example how to do it with the current transcoder. it should be quite easy from the backend side. but something hast to be done in the gui to enable this.

Do you have the link for this thread?

thank you

+1 for this feature the sooner the better imho, im currently wasting neat many tb's of hdd sapce becuase i have to have two files for films i have in both 3d and 2d

Just to give my support for this request.  Would really love to have this feature enabled.

Right but Plex should support two version of movies in the first place. Currently Plex does not care about the movie "versions". Only thing it cares between multiple files is bitrate for optimize transcoding.
Actually which is very annoying. Because if you sync the move with 2 versions it prefers to sync HSBS 3D version over 30mbit BD Rip. just because it has lower bitrates and easy to transcode and you ended up with HSBS movie on your iPad!

By the way XBMC supports 2D playback on the fly it is not a CPU intensive task for player. This could be supported at least on PHT.

I can confirm that this works also together with Plex Media Server if you use XBMC with PLEXbmc as client.

For SBS movies to be recognized you would have to add something like 3d.sbs to the filename. F. ex. "Captain America The Winter Soldier (2014).3d.sbs.mp4"

So for now, if you need this feature there is a working alternative.

but i don't like XBMC and i did not succeed accessing a remote shared library using PlexBMC

An extremely good side of Plex is semplicity in setting things up - workarounds instead can be complicated.

Nobody is going to tell you if and when 3D to 2D conversion will come. At least for now you know that it's doable.

+1 vote: XBMC handles this well. Please ad some awareness of HSBS and other formats and present a Monoscopic option on non 3d devices, like Android, etc. 

+1 for this feature as well. My Samsung TV is able to do this and it would be awesome if Plex for iOS would support it. Then, you could have 1 version of 3D movie that ends up being 2D when playing on an iPad, but stays 3D on the TV.

Another +1 for this feature.
XBMC/KODI have had 3D recognition of the major formats (OU, HOU, SBS, HSBS etc) for some time and does an excellent job of converting 3D to 2D. Given Plex has similar heritage as far as code, I am sure it could be done. It would certainly give me another reason to consider using Plex on all devices rather than the mix of XBMC and Plex.
The PVR functionality is another feature I use in XBMC, but that is for an entirely different feature request.

I thought I’d give this a bump, with the new pre conversion feature being out.
It would be nice to store a 2D version of a movie for play back on non 3D devises.

Cropping doesn’t even cost 1% CPU resources on a Core2Quad. Cropping is extremely simple.
I don’t know anymore for Top-vs-Bottom but for Side-By-Side the format is

[952 pixels wide | LEFT eye] [15 pixel wide | BORDER] [952 pixel wide | RIGHT eye]

The right eye is the same as native 2D. All you have to do is cropping 967 pixels off the left side and resize to 1920.

Giving this a bump. I dont understand why you cant just change the resolution so that it cuts off the screen. still the whole video will be being sent to your device but only make it so that have is viewable and the other half is just off the screen. seems like it could be done client side easier that trying to do it server side before the file is sent. 3d tvs do the same thing by just showing one of the frames and stretching them out.

+1 from me as well. Request a H-SBS and TAB compatible UI in PMP, and the ability for the backend server to transcode same into 2D via simple cropping of the double frame.
