madVR - high quality video renderer (GPU assisted)

[SamuriHL]

I'm getting a 404.

[madshi]

Oopsi, please try again now.

[SamuriHL]

Excellent, thanks!

That's why I don't have the 7970 anymore (I even had three different ones and all were more or less defect by hardware too *wtf*. )

Yup, madVR definitely gives rock solid playback performance now in FSE.
With highered presented frames in advance, I can watch any kind of video without any dropped or delayed frame nor presentation glitch.

What make/models look good?.... I'm no GPU expert but these seems to be similar in processing to a 550ti but with way less power consumption/heat output. I'd prefer those silent(ish) fan designs that dumps the heat out the back of the card.

Guys, I was just following your comments regarding Nvidia vs. ATI. I have always used ATI and currently I run a 7770. Playback has always been pretty solid I usually get about 15 drops frames when I start a movie but then I can watch the entire movie without any noticeable glitches. The only issue I have from time to time is with music playback, I get small drop outs (some time). I use MC17, LAV and madVR in FSE. I watch 1080p/720p exclusively and mostly rip Blurays 1:1 (no compression).

So, I was just wondering why many of you favour Nvidia over ATI? I don't think PQ will be different, is there something I am missing?

[Mikey2]

EDIT: I apologize, I did not read far enough back, it looks like you definitely do know about this.

Has anyone else noticed that the new NVidia driver 306.23 contains the following? :

"Media Player Classic Home Cinema displays a black screen during playback when using the MadVR video renderer. [960463]"

Does anyone know what this means? (I obviously have not seen any issue so serious.)

LOL and congrats on Madvr being under the radar of NVidia itself.

EDIT: If the issue is involved with 0-255 colorspace/BTB/WTW issues, I have been pushing 0-255 to my Pioneer Kuro without any registry fixes with my NVidia graphics card. I thought I had the issues resolved a couple years ago or so and I was displaying the correct colorspace without any "black crush." Am I incorrect? For instance, do I need to run the new "tweaker" Madshi posted a few posts back?

All my problems with Amd were fixed lowering the gpu queues, I'm using 6 frames for that and for the presented frames in advance

This suggests that Mad might consider leaving size of the queues as a setting for users to change in the upcoming MadVR version.

When using a multi-monitor setup, just move the tweaker window to the target monitor (the tweak is per monitor) before applying the tweak. This utility is also able to undo the tweak. Furthermore it should work without needing a reboot. It does that by restarting the GPU driver. Doing that might eventually make your computer explode, or result in your socks catching fire. So USE AT YOUR OWN RISK. Of course it works fine on my PC. But then, my socks are fire-proof...

I tried this but it seemed to make my image to dark. I have tried to tjek the image using the same place in same movie madvr vs blurayplayer. the two images seem identical and correct without this tweak? i have set madvr to pc levels and i have a samsung tv from 2011 (d6530 i think)

can madvr compensate for nvidas defualt tv-leveles setting?

[nevcairiel]

If your TV expects the video in limited range, then you obviously don't need this tweak.
You can however still use it, and afterwards set madVR to TV levels.

GPU in Limited Range/TV Mode:
- Desktop still renders at full range, GPU compresses to limited range on output
- madVR set for PC levels outputs 0-255 -> GPU compresses to 16-235 on output.

GPU in Full Range/PC Mode:
- Desktop renders at full range, GPU outputs as-is
- madVR set to PC levels leaves the GPU as PC levels
- madVR set to TV Levels, leaves the GPU as TV levels (the signal is 0-255, but madVR makes all video only use 16-235)

In case your TV needs Limited Range/TV Levels, the second option may have slightly better accuracy in the colors, at the expense of your desktop being black and white crushed.

thx for the awnser.

i think i figured out my tv has a hdmi black levels setting. so i can adjust what my tv epectrs i think. the question then is whats best? set gpu fullrange with the tweak and tv to exspecy that or go with limited?

[madshi]

Go fullrange if your TV supports it. It results in less conversions being performed, so better image quality for all desktop, games and videos. Of course if your TVs HDMI black level setting is not implemented well, things could get screwed up again. So in the end you'll have to try both solutions and trust your eyes which looks better. Try the madTestPatternSource test patterns to check if you can see a difference.

[Budtz]

kk thx.

yes the tv's blacklevel for fullrange is called normal. I guess sugetsting that the "lov" setting does some converting. anyway with the tweak enabled and black level set to normal the image looks the about the same as with no tweak and a setting of "low". the image was pretty darn good before but i guess i cant see much of a difference.

it so annoying that tv manufatcures insist on using settings names like "contrast+", "motion plus" and "black level" with a normal and low settings. such names say nothing of what the settings actually do. dint know i had the abillity to choose full or limeted untill just now becouse of this. ah well.

[Mikey2]

I just tried running the "Tweak" utility. I was on my 0-255 plasma and it went entirely blank. I had to do a hard-reset of my computer. It now displays properly; however, I notice no difference than before. (I have madVR set to 0-255 and my TV set to the same. Blacks are grey when madVR is set to 16-235.) Furthermore, when opening up the Tweaker, the "force PC levels" is still not checked.

Does this mean that the "tweak" did not take? As I mentioned before, I am not sure I needed it in the first place, but I guess it was a dumb question since no one responded. Well, I'll try again: am I ok as it stands right now?

Boy I hate colorspace issues; they have been dogging me since I first built my HTPC!

Thanks in advance for any help,
MikeY

EDIT: In conjunction with some research on this thread, is the "tweak" simply adding/setting the " SetDefaultFullRGBRangeOnHDMI " key (in My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{B0823740-41FA-45D1-8D11-E547D5CED249}\0001 ) to 1? If so, mine is there and set to 1.

EDIT2: My Mistake, that value is missing for my Plasma. (I know you said the Tweaker was based on the current monitor; I have three monitors and it was sensing the wrong set of registry keys. I do NOT have this value on my plasma, which is the only one I care about. Should I add it?

Once I had this pointing to the correct key, the tweak did in fact work and the checkbox is now on (i.e. I can undo it.) I am still curious on its necessity though...

Oh and I found this link: http://forums.guru3d.com/showthread....43#post4278943
I assume that the first post is the custom resolution that should not be necessary with this tweak? (And the linked post is what your tweaker tool does?

I apologize that this post is pretty scattered; it is getting late and I keep finding out more as I go along.

[THX-UltraII]

Why not just change the .inf file (adding lines HKR,,SetDefaultFullRGBRangeOnHDMI,%REG_DWORD%,1?).
This is a one time procedure and no worries after that anymore.

@Madshi: can we expect a totally new madVR version soon now that NVIDIA fixed the most important thing?
Zou wel zwaar relaxt zijn!

madshi, tested "Use a seperate device for presentation" CHECKED on my Optimus Ivy Bridge/Nvidia 640M-LE video card laptop with the new Nvidia 306.23 drivers and I still have the same problem as before I upgraded the video card drivers in that the playing video will pause by itself in FSE and then try to catch up when I go back to Window mode. This problem occurs when I use Zoom Player and/or Pot Player with my Nvidia card (Run with graphics processor ---> High performance Nvidia processor) instead of the default on-board Intel 4000 Graphics. (Note: that "Use a seperate device... " option checked works fine when I use Zoom Player/Pot Player with the default on-board Intel Graphics so it's definitely an Nvidia problem because it only happens when I use the media player with Nvidia graphics)

So before you decide to remove that option please don't as us Optimus users seem still need that "Use a seperate device for presentation" option....

Ok, 6 months worth of replies, part I:

You could mux to TS and then use TsSplitter. Or you could mux to MKV and then use mkvtoolnix. Not sure, maybe there are better alternatives than these...

For Intel user that would be much much more efficient i guess having not the massive GPU overhead from the Shader Scaling part Especially on the less powerful Intel HD Graphics GT1 and leaving the scaling to the Driver and Egurs Hardware Asic Lanczos4 (Luma/Chroma) implementation

It's on my to do list.

I don't think that's how things work. The processes are supposed to be totally separate from each other. If madVR is loading the dbghelp from directory A, ProcessExplorer can still load it from any other directory without any problems. Anyway, it should be no problem if you replace madVR's dbghelp.dll file with a newer one. Just make sure you really use a *newer* one.

Unfortunately the file got deleted in the meanwhile. I'm sorry, it's my fault for being absent for so long. If you still have the sample, could you re-upload?

I checked with mediainfo that tells me they are, as expected, 23.976fps movies.

Do you know what I could change to make madvr understand it is now a 23.976fps movie ? because when it misunderstands framerate, the info about "one frame drop every x minutes" is false, etc.

Do I need to retag my movies ? how ? Why media info tells me the good framerate and madvr is not ?

Thank you so much

That could have different causes. madVR shows what the decoder is reporting. So it could be a bug in the splitter or in the decoder. Which splitter/decoder are you using?

I'd like to report a few problems with madVR I had since yesterday when I installed my new projector (EPSON TW9000 / 6010 in the US) which supports 3D.
First let me say that I'm truly amazed by the looks of bright 3D. I hate my local cinemas which don't want to invest in new projectors/lamps and simply ruin the pleasure with such dim presentation. I also hate the "authorities" (SMPTE) that agreed that the minimum standard for 3D in theaters should be 4.5 ft-lamberts, while the minimum for 2D is 12 ft-lamberts (recommended 16 ft-lamberts). That's enough hate for the moment - I will simply enjoy my bright 3D home cinema from now on
Now let me share my problems.
Everything started with the stupid limitation of NVidia that I can't have 3D (frame packing) on my secondary monitor - it only works on the primary. I lost a few hours searching the internet why I can't make my new projector run in 3D mode until a friend of mine told me that for him it only works when the 3D HDMI 1.4 display is the primary monitor. Does anybody know if ATI/AMD has the same limitation? Since my PC serves me both as HTPC and a workstation I'd like to continue using my LCD monitor as primary device and have the projector as secondary. This lead to problem 1:
After I watched a 3D movie with TMT I decided to switch back to my default profile (the PJ as secondary) and watch a 2D movie. I did so using UltraMon (if I remember correctly - it was last night and I had guests so I left the report for today - only managed to make a log file) and fired up Zoom Player on the secondary monitor and started the playback. Strangely all I got was audio and a black screen. At the same time the primary monitor was blinking like crazy. I did restart the player but it didn't help. I also tried changing the refresh rate / mode of the secondary display but it didn't help. I then changed the renderer to EVR and it worked just fine, so I was pretty sure it was a problem in madVR. I made a log ("madVR - log - blinking primary and black secondary.txt" - in the archive bellow) and I hope you'll be able to see problem. The only think that helped was a full restart of the PC.

Today I watched more 3D and out of curiosity I decided to test how will madVR behave in this "HD 3D" mode as NVidia call it. So here comes problem 2:
madVR shows a black screen and hangs the player when I try to seek. I've made both a debug log ("madVR - log - black screen + freeze on seek.txt") and freeze report which are also in the archive below.
In this "HD3D" mode EVR is showing images only for the right eye, with the left I see only a black screen.
I've tested the playback both in Zoom Player and MPC-HC and they behave exactly the same.
The Windows' desktop and player UI are OK ... except the right click popup menu in Firefox which behaves the same as the video window - black with the left eye and OK with the right ... also the UI of the ArcSoft's TMT 5 is visible only with the right eye ... but only until I start the movie.
To avoid "problem 1" I decided to change the display mode manually using NVIDIA Control Panel but left the projector as primary - didn't want to go to the PC at that moment. I did change it to a normal 1080p50 mode and the projector changed to 2D mode accordingly. I confirmed the changed and closed the control panel. So far so good. I started Zoom Player again and selected a recording of the today's F1 Australian Grand Prix and all of sudden both the NVIDIA and the projector were back to 3D HD mode !?!?!? How is this possible? What did madVR do to trigger it ?!?!? I'm not sure it's madVR's fault but let's call this "problem 3" for now.
This behavior made me remember something that I read in the notes when I finished the 3D Stereoscopic setup I did yesterday in the NVIDIA Control Panel. I think I saw something similar saying that the next time a player requests 3D mode it will lauch automatically and I don't have to switch manually from the NVidia Control Panel. This sounded nice but the question is "how is madVR requesting this special 3D mode".

Does anybody else have similar issues/experience with NVIDIA, a 3D HDMI 1.4 display/projector and madVR?

Here is the link for the log/freeze report files
http://www.mediafire.com/download.php?2u2niae9xzqgdub

The key problem is the reading VSync scanline information doesn't work properly, anymore. This is clearly a bug in the NVidia drivers. Nothing I can do about it.

Nothing. If it looks better to you, you can use it. If your display is not perfectly calibrated, trying different gamma curves/values could help improving the image. If your display is perfectly calibrated, then using the power curves might be the more mathematically correct option. But it's still a matter of taste. The BT.709/601 curve simply has a different look to it.

I'm using mpc-hc 4164, madVR v0.82.5, LAV from here http://files.1f0.de/lavf/LAVFilters-...1-gd935c59.zip

Apologies if it has nothing to with madVR.

From a quick check I can see nothing wrong. It doesn't seem like a typical freeze, more like a state of not-working. In such cases a debug log helps more than a freeze report. I'm aware of that it's difficult to know for you which is needed in which situation. So if you have the chance, having both is always a good idea, just to be safe. Of course with non-reproduceable freeze, there's no chance for you to provide a debug log. In that case creating a freeze report can still be very helpful. Just not in this case, unfortunately.

I'm not sure. I always have to consider whether adding a new option is worth it. I understand why you want to have that option. But on the negative side, every new option makes the settings dialog more complicated and more difficult to understand for new users. So I'm not really sure I should add this option or not. I think I'll not add it for now. Maybe later. When madVR has reached v1.0, I might have to reorganize all the settings to make everything nicely sorted etc. Maybe then I'll find a way to add options like this without confusing new users...

Thanks

madVR currently does not support DXVA decoding. However, using the latest LAV Video Decoder version, you can still use DXVA decoding with madVR, because LAV finds a way around the madVR limitation. It comes at a certain performance cost, though. So you'll have to try if it runs fast enough on your PC or not.

I've also read that you have vague plans to make the hotkeys configurable sometime. I'd ask you to add an option to at least disable them completely. I don't use them -- at all! Don't have to, maybe never will.However, I'm programming in Emacs at the same time, and Ctrl-R and Ctrl-J are both often used keys that I simply cannot use while madVR is running.

The problem is I don't have any place in the settings dialog where I could place such an option. I'd have to create a new section. And once I do that I can also go ahead and implement the customized keyboard shortcuts. So let me just up the priority on customizing keyboard shortcuts. Shouldn't take too long now...

Nev is regularly updating to the latest ffmpeg/libav version. I'm slower with that. So there's a chance LAV might be slightly faster than the madVR built in decoders. I don't expect there to be a big difference, though. And if there is, it should go away once I update to the latest ffmpeg/libav version myself.

IQ should be the same.

Using NVIDIA CUVID or DXVA moves decoding from CPU to GPU. Whether that makes sense depends on which of those 2 is the bottleneck on your PC. Personally, I prefer software decoding, because it's been more stable and reliable in my experience. But then, if your CPU is a bit slow, or if you want to do e.g. AviSynth processing, moving the decoding to the GPU might make sense. I'd say just try both and use what works better for you. If both your CPU and GPU are equally fast, you'll probably not notice a difference either way.

Chroma always needs to be upscaled, and there madVR should have an advantage. Also, madVR's color conversion (YCbCr -> RGB) should be more exact than what EVR is doing. Furthermore, madVR also applies dithering, not sure if EVR is doing that. Finally, madVR also has a different presentation logic compared to EVR, resulting in smoother motion in certain situations. I'd say, just try them out yourself and check if you can see a difference. Don't just compare screenshots, though, also check for motion smoothness (over the runtime of a full movie) and check for seeking behaviour etc.

Yes, madVR currently does not support vertical orientation. I'll put this on my to do list, but it doesn't have the highest priority right now.

Well, first impression yesterday was not very good. It was smooth (which it was already with my previous one) but like it lacked a lot of punch to the image. I thought it was a matter of PC vs tv settings but did not look like it.
Then I started to think the problem was my contrast and brightness settings were somehow incorrect for this card...no idea why.
So I tweaked those and it started to look better..and details looks more refined (maybe I am using the sharpening in the nvidia settings)
Although in reality, changed to video playback section did nothing only the ones for desktop (the color vibration thing) worked.
So any settings I might be missing? I tried the ones in madvr changing from 0-255 to 16-235 and I can see the change there.

NVidia drivers default to outputting 16-235 when outputting via HDMI. You can fix that by either creating custom resolutions or by using the madNvNVidiaLevelsTweaker (link see a couple posts above).

However, MadVR just treats the whole file as progressive and plays it all at 1080p/25, therefore the interlaced parts show combing.

Thanks, I'll have a look at this.

Is there any reason why it would behave this way if it were only looking at the center of the frame? Also, for those of you who use madvr to watch DVDs as well, do you have IVTC forced on even when the DVD is progressive? Would there theoretically be any adverse affects doing so?

Can I have a sample, please?

The problem can occur if there's a cadence break and there's not enough motion in the middle of the screen for madVR to find the new cadence. When watching the full screen, of course there's more information to look at.

Texas Instruments DLP sets use a wobulation mirror to turn their half-res DLP chip's image into a full 1920x1080 image. This, in effect, is sort of a modified interlacing, where every other pixel (in a checkerboard pattern) is displayed every 120th of a second. What I'm thinking, is that this would allow for perfectly smooth 24Hz playback, without changing video mode from 1920x1080p60, if properly rendered into this checkerboard pattern. It would make sense to be done at the GPU level (simple for a pixel shader to handle). Expand the video up to 120Hz, then merge every frame pair down with a checkerboard mask (top left pixel is displayed first).

Interesting idea. But since I don't have such a DLP, I have no way to test if it would actually work ok. Developing such a solution without being able to test it doesn't sound very attractive to me, and since those DLPs are really very much outdated today, I don't think it's worth the time for me, I'm sorry. There are so many important things I still need to do for displays/projectors which are up-to-date.

You say you have calibrated it. How? Did you use the display controls to do the calibration? Or did you use yCMS? If you calibrated the display by using the display controls then in the madVR settings you should set it to "this display is already calibrated".

Depends on whether you watch in the same lighting conditions all the time or not. If you watch in sunlight or with room lights on, using e.g. a pure power curve of 2.20 might make sense. And that's probably what you calibrated your display to? However, if you watch at night with all lights turned off, going to a gamma curve of maybe 2.35 might make sense. So if you want to switch between different gamma values to adjust for different lighting situations, turn gamma processing on. Otherwise turn it off.

Not sure what's happening there. DVD playback is not officially supported by madVR yet. Could be caused by the splitter or decoder or by bad "team-work" between all filters. Or it could very well be a madVR bug. Maybe I can see more if you create a madVR debug log. Alternatively you could also try different splitters and/or decoders. Also make sure you update to the latest LAV version, just to be safe.

Since then I've been tinkering with settings but nothing seems to work. Switched between driver versions also. (for gts450 BTW) Its the same with both PotPlayer and MPC-HC.
I tried resetting the settings with botha "restore default settings.bat" and manually by searching for madvr in the registry but even that didn't work. The settings didn't get reset to default.

Do you still have these problems? If so, can you sum them up again for me? Your reports are so spread over this thread that I lost overview.

MadVR does the same (chroma upsampling in horizontal direction), but using better (selected) algorithm, but it can't fix what decoder have done.

So, you just need to make decoder to output video without chroma upsampling (in YV12/NV12 format).

Very good analyzation of the problem!

Not at the moment. It's on my to do list.

Looks really good!

Oh well, I'm afraid of making things too complicated. Yeah, it would be nice if the cubic parameters could be manually edited. But already right now this thread is flooded with questions like "which scaling algorithm should I use"? Can you imagine the questions if I allow to separate numeric options which cover everything from SoftCubic to Mitchell to Catmull to Bicubic etc? I'm open to the general idea, but I'm not sure how to do it in the best way for all users (noobs and experts).

I hope you can patch that up in your next cycle.

Please let's look at this later.

Probably at some time in the future, but not soon.

Good idea, will look into it. Thanks!

Makes sense. Maybe I should use the setting to the devices section, so you can set it per monitor? But then, probably nobody is going to look for that setting there! Hmmmm... Difficult...
