How can I watch 3D movies?

Hello everyone,

 

Pardon me for maybe asking a dumb questions...

 

So I have a dedicated Windows 7 machine running PMS, I stream mostly to my Roku devices and iOS.

 

I'd like to know, if I bought a 3D compatible TV, does Plex support streaming 3D media to the TV via the Roku?  I don't currently have a 3D tv and really don't want to purchase one unless I'm sure it'll work like this...  

 

Also:  If I downloaded a 3D movie, would it be able to play in 2D mode also, or are those completely separate file types?

 

 

Thanks for all the help!

If you have a 3D TV you can stream 3D movie files on that TV using Plex and ROKU. I do it on my 2011 Samsung Smart TV. The 3D movie files will have what looks like identical side by side or top and bottom images when viewed in 2D mode so you do need separate 3D and 2D files to watch both. I just have a separate 3D Section in Plex.

On my TV I activate 3D Mode then I am asked to choose side by side or top and bottom mode based on the file I am trying to play. It actually works really well and I am sure the technology has gotten better since I bought my TV.

Thanks!  That answered my questions perfectly.

Sooo, I actually came looking for a solution to my problem when I found this thread.

I can actually watch 3D movies via Plex & Chromecast, but not via Plex and Roku (Roku 2 XD model).  I have both Chromecast and a Roku hooked up to the same tv.  When I use Chromecast it allows me to select the correct 3D viewing mode (side by side), but for some reason the side by side viewing mode is greyed out in Roku.  Wwitching HDMI ports/cables makes no difference.  Any suggestions?  It's not really a Plex issue, and I assume I'd have to get a Roku 3 box for 3D movies to work, just throw that in here so see if somebody has found a different work solution?

I have a Roku 3 model and I can't play 3D with neither Plex Channel nor RARflix channel. If I play the same file with the Plex SmartHub App on my Samsung then everything works fine. Still looking for a solution ...

I can play 3D files no problem to my projector with a Roku 2 XS. I just play them like normal, and then on my projector

I select 3D mode as H-SBS. My projector doesn't detect the 3d files and automatically switch to 3D mode , but if your TV does,

from my understanding, you just have to properly name your files. ie. Smurfs2.avi would need to be Smurfs2.h-sbs.avi, and 

plex will pass that it is a 3D file.

So, there is no option in Plex to switch between 3D and 2D movies. Why not? It is not only the TV, projector or whatever you watch it on, but the streamed signal, left and right or top and bottom images should be adjusted from the player side and not the receiving side (monitor, tv etc.) I guess that this should be an option in next Plex server/client, don't you think so?

Not quite sure what you are asking or wanting. A 3D movie is nothing more than 2 videos placed on top of or next to each other. The TV is what takes this and makes it 3D.

If you want Plex to take the 3D videos and cut 1 off to make a 2D video, there is a feature request for that. Go show your support and like the post. https://forums.plex.tv/discussion/124183/feature-request-convert-3d-to-2d

When i do this, my projector 3D option is unavailable…any thoughts?

From the very last section of the Plex Support Portal at https://support.plex.tv/hc/en-us/articles/200381043-Multi-Version-Movies

“Note: This feature is not intended for situations where you might have, for instance, both a “theatrical” and “director’s cut” version of a movie. Likewise, it is not appropriate for 2D vs 3D versions. Those situations are best handled by Splitting the movie into separate library items.”

Has nothing to do with it. When I have the ROKU box connected to the projector the 3D projector menu item is greyed out.

I have a Sony Bravia 2016 3D capable TV. I have the Plex app on the TV itself, Roku Premiere +, Apple TV 4K, and a PS3. The manual switching of 3D mode on the TV only works for the ps3 of the 4 Plex apps, and of course none are auto detected 3d.

The ps3 is not a good experience, half my files won’t play, all can be played on the VLC player on my mac. I can’t ff more than 150%, doesn’t remember where I left off, it often crashes, etc. I’m looking for an alternative device that uses the full GUI Plex app experience, like everyone other than the ps3 has.

What other devices can handle the 3d files playback, a firestick? If Roku and Apple tv doesn’t work not sure what other streaming devices would. The only android device I have is an old color nook, Is that supported that I can chromecast to the tv to?.

I turned on the DLNA server for my Plex Server because of wanting my 3D movies to work better. My PS3 Plex won’t play Full Side by Side correctly, which I encoded, and doing them as Half SBS the picture won’t play, audio does, but using DLNA to play my Plex H-SBS it plays wonderfully. (This is connected to my Playstation 3D Display)

I have the newer Chromecast dongle connected to the display as well, and using Plex app on my phone or tablet or Chrome on PC to cast my 3d H-SBS movies it also works wonderfully.

In both cases though I have to turn on 3D Side by Side manually.


I have not done much testing with this on my Sony 2015 3D Android TV yet, a PS4 there as well as on the Home Screen, Plex Apps are big trouble for 3D.

I can use the native VIDEO app on the Sony Android TV to play from Plex DLNA server and 3D works out of there, from what I have tried. I’ll be testing more out in morning.

I wanted to do Full Side by Side for all my capable 3D movies, but it’s not working right on my Playstation Display, so Half SBS will have to work for both my 3D screens, and that is what I’ve not tested on my big 3D tv yet.

I tested the Android TV Plex App for 3D Movie Watching on my Sony Bravia a bit ago.

I had no control of the 3D but once the movie started it flickered and changed to 3D display automatically. B)

This was with Half Side by Side encoded 3D.

I’ll need details on how you encoded the file. Plex doesn’t discriminate between full or half. As long as it’s encoded properly, it should work.

This post is what I followed: download the tool, install avisynth, simple choices keep it at .264 and hard code 3D subtitles, change audio to AAC or AC3 …for easy compatibility, then force Direct Play of original file.

I had no luck with FULL SBS it looked squashed down and stretched wide, but yeah, was 3D.

I can’t get any video from those files on PS3 Plex though. Plex Android TV and Plex cast to Chromecast work great with Half SBS.


#17

There isn’t a “force Direct Play” option in the Plex apps anymore, so I’m not sure how you are playing this. You are making the file 3840x1080. Plex doesn’t do anything special with 3D so when it sees this file, it will treat it as a 4K video. If your TV doesn’t support 4K, PMS will transcode the file to 1920x540. Unless your TV has an option to select full-SBS, this will look just like you describe.
