I've been researching for quite a while and I'm still a bit confused...

"Full HD 3D" Bluray is 3840x1080 resolution (ie. full 1080p for each eye). If you use a Bluray HDMI 1.4 player (or PowerDVD with nVidia GT430, etc) you can play these movies on your TV and get full quality.

You can also rip the 3D Bluray to Half-SBS or Full-SBS. Half-SBS is just 1920x1080 and can play with any player.

Full-SBS is 3840x1080 (the same as the Bluray Full HD 3D).

Can XBMC play these Full-SBS files?

I would think that XBMC only needs to switch to that resolution and output the video to the TV, but HDMI 1.4 might do something differently that would cause this not to work...

I am pretty sure that full 3d bluray uses "frame packed" format which strictly in resolution sense is the same as a full SBS movie, but from a 3d bluray something enables the firmware on the video card to send the movie at full resolution.


Point being is that even if your computer could output the resolution that you're talking about I doubt the tv would accept it. I am pretty sure the only way you can get the movie to play in full resolution is to watch it from the original disk or an iso with all devices being hdmi 1.4 compliant.

What is it about HDMI 1.4 (frame packed format) that is different that sending a 3840x1080 resolution signal to the TV?

Right now I'm using PowerDVD with Bluray 3D ISOs but PowerDVD is clunky when switching between XBMC. I was hoping to have XBMC play _everything_ instead of having to switch applications. (ie. I could rip the Bluray 3D video a Full-SBS MKV but playing through XBMC [or any media player] is where I'm not sure how it would work...)

I think you need to use TMT or PDVD. Stereoscopic player may work but I don't think it can bitstrem.

Great question.
I've tried converting some of my 3D blurays to full resolution side by side files using DVDFab 3d ripper. The only player that I found to play them is VLC. I changed the aspect ratio from default to 16/9 and files play fine at full screen. I don't know if I'm seeing all available resolution though.

If your screen resolution is 1920x1080 you certainly see only half resolution for each eye. It is as good as watching Half-SBS file.
Frame Packed resolution is not Side-by-Side, it is 1920x2205 - Top-over-Bottom with 45 empty pixels.
http://www.best-3dtvs.com/what-is-frame-packing-3d/

In order TV to see it in full your video card has to support this resolution. I doubt any card supports desktop resolution like that. AMD HDMI 1.4 cards probably send such frames internally, with desktop being at 1920x1080 as a result of some interaction between player software, video card and TV.

I don't have 3DTV yet but I did some experiments with my HD6850 out of curiosity.
http://www.avsforum.com/avs-vb/showt...2#post19797622

Stereoscopic Player 1.6.6 could not play 1920x2160 file, WMP could. But again, with desktop being at 1920x1080 it doesn't make sense.
Same with XBMC. Can it tell video card to switch to 1920x2205 during playback? If not, it won't work in full 3D resolution.

PowerDVD 10 probably could switch display to 3D mode (if I had 3D display) but it stuttered during 1920x2160 file playback on my 3GHz E8400.

according to a user at mtbs3D
Code:
www.mtbs3d.com/phpBB/viewtopic.php?p=56762&sid=20fd05ed73c4d3b82c74e8a9ce51da31#p56762
, all you need is:
PowerDVD 10 UM3D, AMD 5450 video card w/ Catalyst 10.10 (maybe higher would be ok, too), the DalForce registry hack, Win7 32bit, and a 120Hz display (like the Acer H5360)

This combination allows the AMD card to do quadbuffer hardware acceleration and reportedly plays back silky smooth with very little CPU usage.

With the exception of the AMD card, I have the same setup.

I ordered a $39 5450 card last night from newegg, so soon I will know for myself if this works as they said.

If I use a 3dtv (active like Panny or Samsung, or passive like LG) instead of a pc monitor, it would be possible to play sbs mkv files via hdmi out?

Do other requirements remain the same (registry hack, win7, amd card etc)?

Thanks so much, and sorry for the late "up", but I'm looking for a new monitor (or tv) and I would make the better choice.

I use my desktop mostly for playing multimedia files, so maybe a larger 3dtv would be better than a monitor. Am I wrong about that?

Now with PowerDVD 12 (Released this week) you can play MK3D (MKV 3D FULL SBS Files).

I can play this files using my Intel HD3000 graphics notebooks and a Samsung LED with HDMI 1.4.



The problem right now...is that the playback it's very slow, i think DXVA 2.0 is not working under MK30.

I can play 50Gb 3D Blurays with NO PROBLEMS and 99%-100% smooth, but all the Full SBS 3D MKVs are slow...


Hardware (MBA 2011):
Intel i5 1.7Ghz Dual Core (2nd generation).

Full HD SBS cannot be hardware accelerated, because that kind of resolution is not supported by the hardware decoder, which is why it'll be slow on a low-power CPU like your i5 1.7Ghz

But Why can i play with no problems Full Blurays of 50gb's like Tron 3D and Alice in Wonderland 3D ?

50gb's 3D Blurays are not Full SBS then?

I can play retail 3D Bluray discs Movies with no problems. But can't play 3D ripped (Mkv) movies.

-----

In the other hand...
Will you be able to play Hardware accelerated Full SBS with my current Hardware?

Real Blu-rays use a different encoding for 3D, its not encoded as SBS, the two frames are encoded separately and the hardware can handle that (called H.264 MVC), however "normal" H.264 with a resolution of 3840x1080 is beyond its capability. The frame for the second eye will only store the difference from the first eye and not be a complete independent image, which makes decoding easier and compresses better.

Anyhow, the point is, SBS 3D MKV cannot be compared with 3D Blu-ray discs, they use different encodings. Hardware can accelerate the 3D Blu-ray format, but i cannot handle the SBS MKV format (yet). The next generations of hardware will probably manage some day.

Nice thanks for the information!

I have some questions.

1) So what's is the recommended software for Full SBS Playback? I'm going to build an HTPC soon....A mid-end good Nvidia (like 550 ti) won't improve performance in this situation right? (With the 1.7 i5 DualCore).
"Nor AMD 6990 or GTX590 will help playing 3840x1080 videos right?"

3) Quad-core/Six-Core processors are supported (Used) in Full SBS MKV playback?

Also....
4) Software won't change and support this in a future? For instance "cut full_sbs movies into 2 1080p movies", and use Hardware acceleration with each half? (Or something similar like Bluray disc 3D encoding).

5) It's possible to encode Full SBS MKV 3D back to the original Bluray 3D Format? (3D Bluray authoring or something like that).


Sorry about the huge amount of questions.

Sorry about the huge amount of questions.

so guy with my pc spec below and powerdvd 12 when play full sbs mkv movie is slow and pc usage is almost always 100% so does this mean i need to upgrade my spec to something like i5 3.1 quad core to solved the issue?

My current pc spec
intel core2duo 2.4GHZ
Memory 4gb
Ati 7750 1gb
Window 7 Ultimate
PowerDVD12

Thanks

I was trying to make a 3D HTPC. Then i saw that all new Nvidia cards have a maximum "2560x1600" resolution (even the GTX 690 Hi-end card).

Except for 1 model: GT 640 (low/mid end card) with a maximum "3840x2160".

Maybe i can use Hardware acceleration playing FULL SBS videos with this card.

What do you think?

You should be able to playback full HD SBS clips with Geforce 600 series card (real ones not the rebadged 500 series which litter the low end). DXVA checker reports that 3840x2160 (quad full HD, 2x1920x2x1080) can be played back via DXVA for most codecs (with VP5).

Watch out with the lower end 600 series cards though, they're actually rebadged 500 series cards.

Radeon 7000 series is also allegedly capable of quad full HD though I think Anandtech was unable to test it 3-4 months ago. The Geforce 640 was actually capable of playing it back.

Thanks for the answer!

As far as i saw, the GT 640 is the ONLY nvidia "GEFORCE" card that supports 4K HD resolution. I read that Anandtech review today, it was nice.

The main problem of the card is the DDR3 memory, but for Games.....

I think i will pick up this model for my HTPC...

I prefer nvidia because i really like the Control Panel and cos I'm familiarized with it, (custom resolutions, 3DTV Play, , etc).

The GTX680, 670, 660 Ti, 660 and 650 also support 4k decoding as they all have VP5.

I think they all support HDMI 1.4a through the built in HDMI port as well for 4k/QFHD output.

Anandtech doesn't review the higher end cards for HTPC uses as they're too expensive/loud/hot.

Why so complicated?

You can play FullSBS Files easily with Stereoscopic Player with no Probs.

i think currently only stereoscopic player can play full sbs smooth only with intel icore series processor which i did try on iCore 7 processor and my core2duo processor E6400 cannot play smoothly the full sbs on stereoscopic player.

Thanks

PowerDVD can play SBS (Full) too, with full hardware decode acceleration (4K x 1K AVC decode, that's easy for any modern hardware decoder) and Frame packing output.

For example, I see only ~5% CPU usage with Core i3-3220 (non-K) + Intel HD Graphics 2500.

Is it safe to assume that since I have a passive 3DTV (Vizio 65" which I *LOVE*), whether I'm playing a movie directly off the Blu-Ray or ripped into a Half SBS or TB, the viewing experience will be identical because both frames need to be displayed at the same time?

I could be totally wrong here... smile.gif

Half SBS or TB means the resolution is reduced by half so that you may or may not notice PQ degradation.

That part I get.... but what I *think* is happening when I play a Blu-Ray over HDMI 1.4a, I'm *still*, technically, only seeing 1920x540 per eye because passive 3DTV displays both left and right eye images simultaneously. Thus, I don't really lose anything ripping my Blu-Rays to TB.

Is that correct?

No, you won't lose the resolution with a passive 3D TV. The 3D TV images have only horizontal parallax from the horizontally offset cameras, so the vertical image content for the right and left eyes are in fact identical – but with purely horizontal parallax offsets from their different right and left camera viewpoints. So there isn’t any 3D imaging information that is missing because all of the necessary vertical resolution and parallax information is available when the brain combines the right and left images into the 3D image we actually see. More on this topic.

What about on a non 3D TV. How would you play back a full or half SBS mkv file ?

Ha! You don't unless you like blurry movies. biggrin.gif

Well, I guess you could use an nVidia card to do the red/blue anaglyph to a non-3D TV. I actualy tried this once... it was kind of horrible. tongue.gif

on a regular tv a sbs mkv will look like just that - two very similar looking images on the screen at once next to one and other. if your cable provider sends any 3D channels to you they come in sbs as well. a 3d tv is able to chop the image in half and send each to the appropriate eye.

So I have some full SBS (3840x1080) 3D blu-ray rips (ripped by DVDFab) that I'd like to play in true full SBS, and I'm wondering if I have the hardware and software to do it. Ok, so my laptop is a 3D laptop (120hz refresh rate screen) with an NVIDIA Geforce GT 650M graphics card and an i7-3610QM processor. I believe my graphics card can handle full SBS due to its support of resolutions of up to 3840x2160. I also have powerDVD 12. I've played some of my full-SBS files in PowerDVD and Stereoscopic player with both hardware and software encoding, but they kinda look like they're still in half-sbs like the computer is still not putting the movie out in full 1920x1080 per eye because, if I look closely, the pixels look split into columns of 2 pixels, every pixel looks like it has a duplicate next to it, etc. I've A/B'd it to regular 2D of the same file, which looks like true 1080p, but the 3D does not. Is this how full SBS is supposed to look like? Or am I doing something wrong? Is there a setting that I'm missing or have the wrong hardware?
