Hi

I have various BD 3D.
I ripped them on my hard drive in full form.
The file structure is untouched.
With PowerDVD I can read them correctly, with full resolution 3D active.
With MPC the film is always seen in 2D.
The SBS mkvs instead are correctly viewed in 3D.

I tried everything, any decoder and any render.

The video card is an Nvidia 1080 and 3D Surround is active and working properly.

is there a way to watch movies in full 3D or do I have to create HSBS mkvs?

thank you

MPC-BE support only output row-interleaved output(for TV with passive 3D). If you need frame-packed - use madVR.

I don't require an official 3D4K video, simply a decoder that will decode mvc to a 2D 1920x2160 (or 3840x2160) frame comprised of the left and right eye 1920x1080 views interleaved that can be rendered to a 4k desktop in full screen mode. I don't see how this is so different to decoding any non-official irregular size video file and then scaling to fullscreen.

I understand LAV, or any other decoder that uses the Intel mvc code, decodes mvc to two 1920x1080 eye views (although not separate streams) which are then passed to MPC for rendering, so it does exist notionally as 1920x2160 (or perhaps 3840x1080) data at some point. All I need is for that data to be reconfigured to an interleaved frame and presented to the renderer. An option to reverse the eye views would be useful as there are some titles that don't follow the standard left first convention.

Neither Nevcariel or Madshi are interested in providing this feature, but it would be invaluable for those of us with passive 3D 4k displays as it means both 4k desktop and 3D video can be presented as standard 2D without the TV having to switch modes or mess with the video. It also potentially means that video can be further processed before presentation in an HTPC without relying on limited or substandard TV based processing: not something that can be done with the standard frame-packed output that most developers seem to be concentrating on.

I really hope you will consider implementing this feature for 4k TV/monitor in MPC-BE in future.

MPC-BE can output(using internal video decoder + EVR-CP) 3D video to full OverUnder(1920x2160) stereo pair. Check popup menu "Stereo 3D mode -> OverUnder"

Unfortunately this depends on putting the TV into a special 3D mode to process OU stereo pairs into the TV native interleaved arrangement, at which point the 2D desktop is unworkable and switching between the two a real pain: it's not the ideal approach for owners of passive 3D 4k TV/monitor.

I don't know if you have ever tried to watch a 2D desktop when the TV has been switched to 3D mode, but it's terrible: it's not possible to use the mouse because the location no longer matches the screen position. And every time you need to switch between 3D and desktop, the TV needs to be switched to a different mode. It's hell on the eyes and should really not be necessary in an age of programmability.

Since MPC-BE obviously can create OU 1920x2160 stereo pair, is it so difficult to create an option of an interleaved 1920x2160 stereo pair? It would really help us passive 3D 4k owners.

I think you already have an interleaved option, but it filters the vertical resolution to cater for 1080p passive displays. Perhaps you could add a special new 4k interleaved option that simply ignores the filtering of the current 1080p interleaved version? I would be prepared to accept a garbage 3D window if it meant fullscreen was unmolested 3840x2160 interleaved 3D.

I don't have a 4K 3D TV and can't test and watch a result. Maybe somebody sponsor to improve development

Test build - https://yadi.sk/d/yoHTeCw23SqsDw
Set "Stereo 3D mode -> Auto", it's output to 1920x2160 interleaved mode.

I'm more than happy to test any development code you might implement for this feature.

IIRC you already have an interleaved option, so the code should be virtually the same, minus any code to downscale the 1920x1080 eye views before interleaving.

Alternatively, you could take the output of OU and remap to interleaved (might be the better option as subtitles, etc are all taken care of already).

Thanks for that.

I found I needed to install the Intel Media SDK and tick the H.264 (3D MVC) decoder option in addition to using your test mpc-be.exe before it would decode MVC, but now, in Stereo 3D Mode = Auto, I am getting the full 1920x2160 interleaved 3D.

I also have to activate Video->Stretch To Window for fullscreen to scale 1920x2160 to 3840x2160 but it appears to be working as I had hoped.

Is there a way to force Stretch To Window every time, or is there another way to activate scaling permanently, as it only seems to remain active for the current instance of mpc-be.exe? I'm guessing it has something to do with not processing aspect ratio or something, but it's currently working quite well as it is. I'm impressed with the clarity compared to my 3D Bluray player.

In Auto mode it's only displaying a 2D 1920x1080 frame: there doesn't seem to be any 3D decoding happening.

Row Interleaved produces a weird interleaved version of an Over/Under presentation, whilst OU doesn't do anything.

Is your mpc-be.exe standalone or do I need to download or install any supplementary files like Intel's mvc decoder?
Yes - you need Intel's mvc decoder. Can download here - https://mpc-be.org/Intel_MSDK/

Options -> Video -> Framing -> Default mode - it's options remember.

As i understand - 1920x2160 row interleaved mode is working good ??

there is a bug about “save image” and “save thumbnails”

“including subtitles” is NG, image file always with subtitles

Don't confirm. Maybe subtitles embeded in video or use VSFilter.

Okay, except "Stretch To Window" is not the best for conventional videos where "Touch Window From Inside" is usually the best default.

Yes, it is performing exactly as I had hoped. Thank you again for making the code change.

Perhaps Auto is not the best tag for the 4k interleaved option and it might be better to have separate 1080p Interleaved and 4k Interleaved options. To me, Auto means automatically selecting the right option, but the software can't know if you want SBS, OU or Interleaved.
