3D 4K video

Question

Hi everyone... I recently got an LG 55UB850V which I'm really enjoying. I'm under the impression that as it's a 4K TV it's capable of 3D pictures in full HD like you get with an active 3D TV and have tried to encode a couple of my blu-rays as Full HD side-by-side h264 for streaming over DLNA. I'm not having much luck, though, as it doesn't seem to like my 3840x1080 MP4 files. I've searched around and can't find any answers anywhere but wondered if anyone knew what 3D encoding would work to get the full HD experience from the 3D without using a blu-ray source.

Hi Irwell,

i got 3D Full HD working on SmartShare in every container like MP4, MKV and MTS but not

over DLNA, i read in the specs that by design 4k is not available over DLNA. I have external HDD

connected to USB 3.0 port.

 

Anyway i got it working after many try between compatibility and image quality.

I can say that SmartShare is unable to play SBS 3840 x 1080 becouse 

the WIDTH (3840) is initial step to determinate if the resolution is 4K. And if it is

2160 height is expetced. I really don't know why. I tried Many othere video with

mixed resolution more close to 4k like 3840 x 2000 and fail to play.

 

So to get Full HD SBS i upscaled 3840x1080 to 3840x2160 in SBS to get 4K full resolution,

and with passive 3D i got full resolution per eye.

 

I success in some case to put two videos OU (Top Bottom) instead SBS

to get 1920x2160 instead 3840x1080 but nevere tried over DLNA.

 

Hope to be in help,

Stefano

I run Serviio DLNA on my PC and my UB8500 can stream 3D just fine.  The 3D files I have are mkv SBS format.

 

P.S. I only have 1080p files.  I don't have any UHD to try it yet.

Hi Stefano,

 

I am very interested in your result. I am trying to achieve the same thing than you I think: Play full resolution (full hd) 3D files on my Lg 4k tv. And from my NAS as a bonus!

So you said that 4k isn't supported at all by DLNA? Good to know. I thought that DLNA was just "serving" the file... Because yes I have some 4k videos that play well from a USB connected HD but not from my NAS. It is sad that WebOs cannot connect to a SMB shared folder.

 

As for the 3D. What is your process? What software(s) are you using?

Is your source a bluray 3D?

 

In my research on playing full resolution 3d, I also found some discussion about "3D Frame Sequential" format (http://forum.doom9.org/showthread.php?t=170863). The sample clip posted there play perfectly on my tv. Best of all, the tv detect that it is 3D content and switch automatically!

But this forum is really really technical and I didn't understand yet how to create that kind of mp4 from a bluray. I also read somewhere else that using 3D Frame Sequential format is bad because the video encoding is trying to compress between the right and left eye images and that cause a lots of compression artifacts.

If only WebOs could be able to play MVC MKV files...

I've live in italy.

i've buy a LG49Uf7767 , and i've a NAS Sinology.

 

I don't see my 4k video files streaming over DLNA.

 

It is a work-aorund ?

 

Hi Masssimiliano,

there are no workaround on WebOS 2.0, maybe on V3.0

----------------------------------------------------------------------------

 

Ciao Massimiliano,

anche io sono italiano, purtroppo sembra che non sia fattibile

fare stream 4K da DLNA su WebOS 2.0, così dicono le specifiche tecniche.

Forse nella versione 3.0 ci sono più focus sul 4k.

You are not able to stream 4K media, and in case of 1080p - with file sizes larger than 1GB - you probably won't be able to rewind/fast-forward (at least I can't). WebOS is soooo good - isn't it, isn't it?

I should have gone with some other brand, offering great picture quality (LG LED's are apparently far from this) and stupid OS, and then add some good streaming media player...

Hi,

by design WebOS is unable to process 4k resolution via NAS / DLNA, this is a limitation of SmartShare.

About to play full resolution 1920 x 1080 per eye in SBS i got it working with BDtoAVCHD (http://www.connecta2000.com/BDtoAVCHD/?lang=en)

Is free, works and can be scriptable with avisynth to get MKV SBS up to 4k resolution and you can also encode video with x265 !

SmartShare is able di recognise this SBS MKV 3D automatically and play immediatly with 3D on !

How and using which software did you prepare 1920x2160 OU from 3D Bluray iso?
