Does anyone know if besides xySubFilter there is another subtitle renderer that is able to properly parse and show 3D subtitles?

[huhn]

try the internal subtitle filter in MPC-BE.

ISR supports 3D subtitles for madVR for a long time in MPC-HC. Not sure if changes were backported to MPC-BE like huhn suggested.

An external 3DLUT is always hard coded to one specific peak brightness value, so it doesn't make sense to provide any metadata to a 3DLUT.

Why? 10bit output is an option you can choose yourself. You should know if you have it enabled or not, shouldn't you?

Madvr seems to trigger the windows switch is that correct?

Last time I checked with the NVidia drivers I was using both switches were "identical", so to say. Changing one switch also changed the other one. If that's no longer the case that would probably classify as a GPU driver bug, I suppose.

1. can you add keyboard shortcut for 3D swap l/r eye.

Why? This should be handled automatically, if the source file has the correct information stored.

is it possible to make an keyboard output for this? 16:9 -> Alt....+y; 4:3-> Alt...+x (just an Example)
so we could use it for automatic Ambilight switching.(with Ambibox for example)

Keyboard output? What do you mean with that?

Sounds like a GPU driver issue to me. Probably 2160p at 12bpc is not supported by "someone" (either the GPU or receiver or display), so somebody does some conversions somewhere which screw things up. This is most probably outside of my control and not my fault.

Resolution automatically switches to 1080 (from my 4k default), however 3D in the OS is not enabled, so video is shown 2D only. To fix, I have to manually go into nVidia settings and enable Stereoscopic 3D myself every time.

I keep saying, Windows 8.1 is the best media OS atm. I don't think this is my fault, probably a GPU driver issue.

Both computers are in the same network, LAN access is enabled for madr and firewall rules are set up. But i am still not able to use the pattern generator via network.

I have tried shutting down antivirus and firewall as well... still no luck.
Madvr is only installed on the HTPC and i am trying to access it via my notebook where madvr is not installed.. i have installed it for testing and enabled to show the icon only when there is another madvr instance on the network and it does not show up as well.

Is there any way to test if madvr is working correctly and is reachable in this regard?

Anything special i need to take a look at when using windows 10 ?

I'm not aware of any special needs. It usually works just fine for me. I'm not completely sure if dispcal/HCFR allow you to ender an IP address, or if they always rely on the automatic find routine? IIRC Calman allows to enter an IP address, in case the automatic find routine fails for some weird reason...

I'm basically looking for a way to encode HDR clips / movies to regular SDR files in the way madVr does the converting / compression. It looks awesome (to me) and that way I can take the movies with me on tablet or in the non-HDR tv in the bedroom.

I'm converting it now manually, and I tweak it manually with a final gamma adjustment and a levels/histogram adjustment to get it looking nice. But madVr's way is nicer, and my way probably works fine for shorter clips but for longer clips or full movies it will look nice in one part but horrible dark or bright in another part :S.

It's not possible atm. It's on my to do list to investigate, but it probably won't come too soon.

Fow now you could try using displayCAL to create HDR -> SDR conversion 3dluts and apply them using avisynth. I think there's some avisynth script from tritical available which can handle madVR 3dluts, IIRC? Quality should be identical to madVR, or even slightly better.

Do I just need to activate the stereoscopic mode in Windows and run a calibration through madVR/DispCAL?

I suppose so. Haven't really tried myself. I hope left and right eye will need the same calibration...

Please note that in order to measure shader passes I have to flush the GPU and wait for the rendering to succeed. This will actually slow overall rendering speed down. So I wouldn't bet on that each shader pass actually takes that much time when not forcing the GPU to flush after every render pass.

Annoying, but I'm glad they did this before I published NGU and not after, so I could add a little bit (not too much, though) of protection against reverse engineering.

I don't really like the look the Darbee produces, but I think you can achieve something similar by using the madVR "image enhancements" or "upscaling refinement" option. Furthermore, if you have a 4K display, the Darbee does its work in 1080p and the result is then upscaled somewhere to 4K, while with madVR you have the option to use a better quality upscaler and then sharpen in 4K, which should produce noticeably superior results.

Been testing same movies with Pioneer blu-ray player and the subtitle depth is correct with that.

A few questions:

1) Can you describe in more detail how the subtitle depth goes "wrong"? Are the subs too far in front or too far back or jumping around or something else?

2) Does the same problem always occur at the same play time with the same movie? Or does the problem sometimes not occur if you rewind back and play the same movie section again?

3) If you can perfectly reproduce the problem and if it always occurs at exactly the same movie runtime, maybe you can create a little sample for nevcairiel and me to look at?

MadVR reliable detects the actual aspect ratio and also sends this info optional to the media player (JRiverMC in my case). So it might be possible to adjust motorized screens to respective aspect ratio. I tried jriver http commands, but I don't think this info is available there. In madVR OSD the aspect ratio is shown, but I don't know how to get hands on this info. Maybe someone could give me a hint. It would be great if mediaplayer or better madVR could send UDP Broadcast with current movie aspect ratio. This might be a very cool additional feature for madVR.

One thing you could do is create profiles for different aspect ratios and setup rules to auto activate the matching profiles. Then in each profile you can define a command line which madVR shall execute if said profile gets activated.

Unfortunately the command line execution is currently not implemented yet <sigh>.

The latest drivers have a better API than the one you linked to, but I don't have the API documentation yet. I'm waiting for it to be released.

Quite everything I need is already there and right before my eyes. You can easily use profile scripts to detect AR and switch profiles accordingly. There is an option "command line to execute when this profile is activated". Unfortunately there seems to be an issue with this option. I couldn't get a simple command to be executed (e. g. curl command for http get). I also found an old bug ticket: http://bugs.madshi.net/view.php?id=210 which hasn't been resolved. If anyone has experienced the same, do you have a workaround?

I'll increase priority in my to do list.

Yes, it does. But it's also about a 100x slower than NGU.

I haven't heard from tritical in years. NGU is not based on NNEDI3 in any way. E.g. NNEDI3 needs OpenCL (or D3D11 shaders) to run with decent performance. NGU runs in simple PS3.0 pixel shaders.

Nobody has had a hand in NGU other than me. Well, of course I must have read several dozen scientific papers about image processing and upscaling, and I've certainly taken many good ideas from several such papers, and added a couple of my own ideas.

Doesn't look all that great to me, to be honest.

Catmull-Rom in gamma light is pretty realistic. You could argue that a box filter in linear light is closer to how cameras work, but I'd be surprised if it resulted in a huge difference in the relative quality of the scaling algorithms.

Agreed.

I have an "ultrawide" 21:9 aspect ratio monitor, and I use madVR's settings under Processing -> Zoom Control to zoom/crop past the hardcoded top & bottom "black bars" of most movies.

The problem is that subtitles are still rendered as if those black bars are visible.

Does madVR correctly detect the movie aspect ratio? Check the OSD (Ctrl+J) for that.

Which subtitle renderer are you using?

Actually, madVR is supposed to be able to move PGS subtitles, unless they're encoding in "fullscreen". But most PGS subtitles I've seen are encoded in small rectangles.

I have a 21:9 setup myself and moving all subtitles (including PGS) into the active image area works just fine for me.

madVR v0.91.0 released

http://madshi.net/madVR.zip

* added new NGU (Next Generation Upscaling) algorithm
* added "soften edges" + "add grain" upscaling refinements (atm only for NGU)
* display properties can now also be profiled

A few comments about NGU:

1) Obviously, I've decided to change the name from "NG1" to "NGU". The reason is that "NG1" didn't have any mention of "upscaling" or "super resolution" in the name. So I added the "U" for "upscaling".

2) In this initial version only 2 quality levels (high and medium) are available. A future version will add at least one more level which is faster than medium, maybe there will be even more levels, I don't know yet.

3) NGU is currently available for both doubling and chroma upscaling. The chroma upscaling algo does currently not make use of the luma channel. I plan to try adding that to a future NGU version, but that will take serious development time, so don't expect it too soon.

4) NGU doesn't need OpenCL, DirectCompute or D3D11. It runs fine with D3D9, so it should run fine in XP.

5) A word about "ideal upscaling": When trying to upscale a low-res image, it's possible to get the edges very sharp and very near to the "groundtruth" (the original high-res image the low-res image was created from). However, texture detail which is lost during downscaling cannot properly be restored. This can lead to "cartoon" type images when upscaling by large factors with full sharpness, because the edges will be very sharp, but there's no texture detail. In order to soften this problem, I've added options to "soften edges" and "add grain". Here's a little comparison to show the effect of these options:

low-res image -- | -- straight NGU -- | -- NGU + "Soften Edges" + "Add Grain" -- | -- Jinc AR

I hope these extra options will make NGU acceptable for all of you, including those who preferred Jinc so far.

Now I'd like your feedback:

1) Do we still need NNEDI3 image doubling? Or can NGU completely replace it?
2) Do we still need SuperRes (image doubling)? Or can NGU completely replace it?
3) Do we still need NEDI image doubling?

I'll not ask about super-xbr image doubling yet because I've not scaled NGU down to that performance level yet.

[Dreamland]

Excuse me for my very bad english
Thx for new great release !
I can't install new release MadVr on win 10 Anniversary Update ( 1607 ) 64 Bit

[madshi]

Did you have an older version installed? In that case you can just copy the files over, no need to uninstall again. Otherwise try right click -> run as admin. If that also doesn't help, you may have to run "regsvr32 madVR.ax" manually in an admin command line window.

Thanks Madshi! Very good job

Where do I can find soften edges and add grain?

I'm waiting for a more scaled down version , too hungry for me (GTX 730)

I have older version inside MPC HC folder and works very well ..
this release doesnt work (click -> run as admin as always )

edit

copy the files over an older last version and works

Does the old version still work? If yes, just copy the new files over the old files and you should be good to go.

[Dreamland]

I copy the files over MadVr 0.90.24 ( no unistall )

and now i have new release

I used the manual method you just described. But I can also confirm that the .bat file does not work on Windows 10 anniversary update (all other updates installed). Previously it worked fine. It just shows a black screen now. This is with running it as Admin, too.

[madshi]

Does the 90.24 batch file still work? Just wondering if something unexpected changed in 91.0 or if the anniversary update is causing the issue.

Yes that batch file still works. i just rolled back to 90.24 using the old .zip. couldn't get the new version to work even when manually registering it. copy over method was the only one that eventually let me use 91.0

[madshi]

Interesting, must be my mistake then.

[sneaker_ger]

madVR v 0.91.0 doesn't react to any keyboard shortcuts for me. Old version fine. Resetting settings doesn't help. 32 bit and 64 bit affected. MPC-HC + MPC-BE affected. Windows 7 x64 SP1.

https://www.sendspace.com/file/bcop6k (log, start video in player, press ctrl+j, close player)

[imhh11]

thanks for the new version. But i cant install it too. Admin or not.
Keyboard shortcuts are not working too.

[huhn]

FHD to UHD 23p
nnedi3 64 luma only cost about 17 ms
NGU high quality luma only takes about 71 ms
nnedi3 256 luma only cost about 67ms

this is not working as intended or?

edit: installer is broken for me too.

Strange. madVR must be thinking your running it inside of a debugger or something. Do you have any debugger type of stuff running?
