madVR - high quality video renderer (GPU assisted)

[Xello]

I posted up a couple of threads regarding the auto refresh rate in MadVr. I did some more testing and MadVR refresh rate does indeed work. Only on certain videos though. When playing Hancock the refresh rates stays at 60 instead switching to 24.

My chain is Nvidia Audio decoder
NVidia video decoder
MadVr

It may be that the decoder is the culprit, but not sure why the refresh works on some titles and not others. When I press control J the stats show 23.976 for all titles.

Might be a possible bug...

:thanks:

Not sure, I find the refresh rate changer is working fine, i'm just dying have an option where it changes only in fullscreen.

These are the modes I list in madVR:

1080p60, 1080p50, 1080p24, 1080p23, 1080i60, 1080i50, 1080i24, 1080i23

Also using Reclock 1.8.7.7.

Can you upload a sample of a file where it is not changing for you?

[racerxnet]

Xello,

What is your chain you are using? All my movies are DVD's ripped to the drive. No BlueRay at all. CCC does not list 23p as a output rate. 24 does show. If you have a DVD of Hancock give it a try and see what your results are. I just downloaded FFDshow and will try that. Using Reclock as well.

That's been there also IIRC about since the 5000 cards came out. AFAIK no one ever figured out what it does, or that it makes any difference in any configuration, at least in the couple extremely long ATI 5000 threads at AVS.
Thanks.

So do most people disable it just in case?

Hi and Happy New Year,

I have a LG 42LD450 television and have been trying to use the auto refresh rate of 23.976 to 24.00 and 29.970 to 60 in MadVr/ReClock. When I submit 1080p24 and 1080p60, MadVr will only use the first resolution submitted in the box. The EDID does not list 24p as a standard resolution, but when changing the refresh rate in CCC I am able to output this rate of 24hz.

Here is what I want to do:

23.976 to 24.00 @ 1920 x 1080p 24 exit back to 60p when done
29.970 to 60.00 @ 1920 x 1080p 60 exit back to 60p

My set up is Nvidia audio and video decoder, MadVR, MPC-HC with Media Portal as the front end. I tried Autofrequency with no luck. I followed the guide several times.

WinXP SP3
QX9650 2 gigs ram


Any help would be appreciated in getting this to work.

Hi,
I think the issue is outside of madVR and we can assign this to faulty drivers. I dont have a Nvidia card to test for 24Hz playback back to 23Hz original, but CCC AMD HD5670 has never showed 23Hz in the refresh rate field ( when entered ) and instead everytime showed wrong value 24Hz ( although being actually set on 23Hz ).

Scenarios:
1. If I have the restore function ON in madVR, 60Hz original rate and madVR changes to 23Hz ( 1080p23 ), it works fine out there and back.
2. If I manually change the rate to 23Hz before opening player with a movie ( value is being showed as 24 during the playback ), going back to 23 after exiting the player has zero effect, because the value 24 is due to the driver bug already there.

Hope this helps.

Hi Pluto,

Thanks for the info. I can get the refresh rate to change on some movies but not others. I am looking for any clues as to why. Control J reads the rate at 23.976 on movies that work or not with Nvidia decoder. Arcsoft decoder reads 25.00 FPS and it does not refresh on any known movie to work. MPC's internal decoder does not even output any FPS when viewed with control J. Hence no frame rate switching either.

Movies that change refresh rate are 100% repeatable.
Movies that don't work are 100% repeatable in that they won't change refresh rates. This is all SD content ripped to the drive. I tried the disk as well and the results are repeatable as above. It appears to be a bug in Madvr. I will try another driver to be sure.

Thanks for the help so far.

[racerxnet]

Upon further testing tonight I found that whenever there was no vsync correction in Reclock there would be no auto frequency change from MadVR. It did not matter if the disk was ripped or not, the same results happen. I tried the latest AMD driver and the results were the same. All the new driver did was bork the desktop scaling. Back to 11.3 for me. FFdshow still shows 25.00fps and no luck. I am having limited success with Nvidia Purevideo decoders.

Not sure if Madshi can resolve this or not, but worth taking a look at. This is for SD DVD playback.

SD DVD @ 1920 x 1080p

I don't have that one. I don't actually have alot of SD content, almost all HD.

I'm also on an Nvidia card so probably different systems altogether here, but I'm using mpchc x32 with lav filter, lav audio decoder, lav video decoder and reclock. I'm not sure if my panel can switch to 23.x hz exactly or not but some things suggest setting this option so i just put in both 23 and 24, and reclock tends to be reporting 23.971hz as my refresh rate when watching stuff. Panel is Panasonic VT30.

I also have everything under the V-sync options in reclock config unticked, as per the guide on homecinema-hd.

[HitomiKun]

So after my little problem here:
http://forum.doom9.org/showthread.php?p=1544667#post1544667

I passed the information to ffdshow devs like you told me madshi. They told me that it's impossible to fix this and that the container was badly muxed/encoded. I recommend you to check my bugreport here so you may could find a fix for this problem:
https://sourceforge.net/tracker/?func=detail&atid=867360&aid=3461550&group_id=173941

Yamagata said that the problem could be fixed if madVR would get the fps rate after recieving the first 3 frames, thus allowing to switch to the right Hz rate. That would may be a good and secure way to get the right fps/hz rate. Just for future containers that muxed the same way.

I used to mux without extra typing the fps rate in MKVToolNix, since MKVToolNix did not complain about any errors and MediaInfo showed the right info. (I think that MKVToolNix did get the right fps, but it didn't store that information on its header) After I remuxed my video with additionally typing the fps rate in MKVToolNix, madVR chose the right Hz rate.

[e-t172]

I just noticed that my GeForce 9400 GPU is too slow to play 1080p30 content (on a 1080p display) using madVR with default options. So I need to lighten the load a little bit. The problem goes away if use 10-bit precision chroma *and* luma buffers, or if I disable dithering. Switching chroma upscaling algorithms doesn't seem to make much difference.

I have two questions:
- Is there anything else I can try to improve performance? Note that I'm using CUVID for decoding.
- If not, what's the best option between using 10-bit for chroma and luma, or disabling dithering?

The Windows MKVMerge GUI warns that inputting a value for FPS is mandatory with h264 streams otherwise it will assume 25FPS I believe. No such warning with the CLI?

There's something different in 0.80 that is completely messing up things for DVD playback. I start a DVD in Open Disc, it switches resolution, I get Macrovision Fail (monitor stays in 50hz), then I go Open Disc again and the DVD can play. I've also noticed very often menus can fail to navigate and MPC will utterly crash.

That is strange, because I feel that 0.80 has fixed mpc-hc freezes and I was able to navigate DVD-menus, which was a pain before:confused: But, I quess these "fixes" are not related to madVR, so make sure you are using the latest version of mpc-hc;)

[JarrettH]

I'm going back to 0.79 to double check...

Also, I noticed with Chrome or Aero Composition or something that I occasionally lose the min/max/windowed buttons for my Chrome session and the tabs will become unclickable and I have to right-click the quick launch icon to close window. The window will also It seems like madvr is doing a heck of a lot of work when switching resolutions in 0.80; it blanks out twice recomposing the screen and not very gracefully.

Edit: I just tried 3 DVDs that all previously crashed on menus with 0.80 and they work fine in 0.79. When it does happen the menu basically locks, the cursor does the spinning/timeout animation, MPC soon stops responding and I have to X it out.

Using 3931 of MPC and 3887 before that

@SamuelMaki yeah there were a lot of nice fixes I noticed myself too, I hope I can log something for madshi

I had this. I ended up doing a system restore and installing mpc+filters again and I haven't had the problem since.

Under rendering > general settings, I have the top 3 options unticked, and every other option ticked, so that it only disables aero when in fullscreen mode. I'd rather not have to disable aero at all but with 24fps AVC i was getting major judder in fullscreen mode with aero active. This is on 0.80.

e-t172,
are you forced to use CUVID? What's your CPU?
In the past I've noticed that using software decoding and leaving the GPU only to madVR gives me better results.
Sorry but I can't recommend which performance setting to enable in madVR.

[e-t172]

Well, I probably could use my CPU for decoding. Problem is, it would run near 100%, and given it's the stock Intel cooler, I would prefer to avoid the added noise.

So it happens with Chrome too, huh? I thought it was Firefox bug.
Anyway, it seems that's side effect of desktop composition disabling/re-enabling added to madVR. It happens quite often, but I haven't found a way to reproduce it anytime I want.

There's another thing that puzzles me. With the help of AutoHotkey and simple script found on their forums, i made two executables for turning Aero off and back on (http://www.mediafire.com/?ckp7465o0xnxhl3).
One disables composition and waits for closing the message in order to re-enable it:
DWM_EC_ENABLECOMPOSITION:=1, DWM_EC_DISABLECOMPOSITION:=0
DllCall("Dwmapi.dll\DwmEnableComposition", "UInt", DWM_EC_DISABLECOMPOSITION)
MsgBox, Aero should be off. It should turn back on when 'Ok' is clicked.

The other one disables Aero and immediately re-enables it:
DllCall("Dwmapi.dll\DwmEnableComposition", "UInt", DWM_EC_DISABLECOMPOSITION)
DllCall("Dwmapi.dll\DwmEnableComposition", "UInt", DWM_EC_ENABLECOMPOSITION)

Although the latter one prevents taskbar from auto-hiding (I must execute it twice to have taskbar hide), it never causes disappearing of Firefox's control buttons. Not to mention the first script have no negative side effects whatsoever. The switching is done more or less the way described on Microsoft's site (http://msdn.microsoft.com/en-us/library/windows/desktop/aa969510%28v=VS.85%29.aspx) - script is calling dwmapi.dll. MadVR on the other hand is calling dwmapi.dll only to check if Aero is running, and then is calling uxtheme.dll to disable/re-anable composition (or so it seems - I checked it with API Monitor).

I'll risk sounding extremely stupid :D, but could it possibly be the cause of disappearing buttons in Firefox and Chrome?

Cheers,
SB

The Windows MKVMerge GUI warns that inputting a value for FPS is mandatory with h264 streams otherwise it will assume 25FPS I believe. No such warning with the CLI?

Nope, because I encoded with x264 and output the final file in a mkv container. MKVMerge GUI just gets the fps rate from it. (I'm encoding video and audio separately so I have to remux the finished file from x264.)

By the way...
I just updated my NVIDIA graphic driver to the newest beta driver (I had to because I had some lags and displaybugs in Battlefield 3) and automatic Hz rate change seems to have stopped working entirely. I'll try to reinstall madVR in a sec and see if that fixes the new problem.

Edit: Nope. Reinstalling didn't solve that new problem. Does madVR always need to be adjusted to a new (main) graphic driver update from NVIDIA/AMD?
The NVIDIA driver I currently use is version 290.53

I just tried a few files with different fps rates, even my container that was muxed badly, it stopped switching completely.

Edit 2: Nevermind, I just went through some logfiles I made and then deleted and readded the 72Hz mode for my screen. That solved the issue. Now back to this: http://forum.doom9.org/showthread.php?p=1547868#post1547868

The NVIDIA driver I currently use is version 290.53I always seem to have issues getting presentation glitch free playback when running beta Nvidia drivers, which is very annoying because usually shortly after there is a WHQL release (every couple of months) there's a new big game release which then requires beta drivers to perform well.

That said, running the 290.53 drivers seems to have fixed an issue I've had for quite some time now, where MPC-HC would freeze up when switching to the next file in fullscreen exclusive mode. (never happened in windowed)

I'll have to check and see if MPC-HC intermittently freezing up when changing resolutions has been fixed too. (though the resolution switcher doesn't seem to work with DVD playback, so I still end up having to switch manually a lot of the time anyway)


It's annoying but I've just learnt to live with it, as I'm sure things will be fixed eventually.

Hi im new here and decided to sign up to ask some questions about madVR.
I installed madvr about a week ago and i rly like the improvement in picture quality. But i have one big problem. Since i installed madVR i get rly short micro judder from time to time (always at same place in a video). I checked my hardware and i only got 20% GPU and 40-50% CPU load. Also i dont have any droped/delayed frames or presentation glitches. I use mpc-hc, LAV, haali combination with madVR. If i run the movie with wmp 12 for example i get no judder at all.

If someone could mb help me with some settings to fix the judder. I am at a point where it is rly freaking me out ^^

PC is a 8800GTS 512 and a C2D @ 3,4 ghz 4GB ram

I'm also having micro-stutters with madVR, as opposed to EVR, for instance. It happnes not only with v0.8, but also with v0.79. I have not tried with older versions.

This happens on any 23.976 video material, played on a 60Hz (actually 59.6Hz) display monitor. And it's most visible on panning shots, or white-on-black movie end scrolling credits. In the other cases it probably still happens, but it doesn't jump out to me like in those two cases.

The playback chain is exactly the same in both cases: MPC-HC + Haali for mkv splitting + LAV filters for video and audio decoding:
- when using EVR as renderer, the flow of the video is smooth, although a little blurry
- when using madVR, the image is crisp, the flow is smooth until it suddenly jitters a bit, then smooth again, then it jitters again

This is very easy to reproduce with any 23.976fps mkv, on the movie scrolling credits, I believe.

I'm surprised your i950 is at @4.5Ghz still 100%.
Can you turn on hyperthreading to test ?
Using my i970 (6+6 cores) I have < 10% load on decoding h264 1080p60 with software lav decoder.
The benchmark says 360 fps average on same h264 1080p60..
This is all with hyperthreading on and put the number of threads on 12 in LAV-video.

It should be easy to handle 24fps on 60Hz monitor

suppose 2 frames from the 24fps movie : 1 2
for displaying on 60 Hz we need 5 frames for the 2 frames above. (60/24 *2 = 5)

going like this :
1 1 2 2 is for 48 Hz monitor
1 1 X 2 2 where X is blending frame 1 en 2, for 60 Hz monitor.

This should give fluent playback from 24 fps movie content on a 60 Hz monitor.
I hope Madshi will find some time to implement this in MadVR.

PS: for 23.976 and similar content one could use Reclock to speed up to 24 fps

MPC hard crashes on DVD menus...the cursor will show the spinning time-out animation, menu music stops and the program will crash shortly after. I don't know if this is an MPC or madvr problem or how I can help solve it. I'm using ffdshow as the mpeg2 decoder, a GT240 with 275.33 drivers and Windows 7 32-bit

This is so frustrating, I can't even tell you the unimaginable amount of times it happens...8 out of 10?

I think I've had this problem for a while now, but it seemed intermittent and I didn't really care that much. Just recently I decided to check it out, and narrowed it down to it happening the first skip after a refresh rate change. After it freezes and you close, it doesn't happen until after you play the next file with a different refresh rate. Using D3D11 fixes it completely, but it has its own problems.

A simple test using EVR, shows that this renderer seems to manage smooth playback even in these conditions.

Therefore, there must be something that Microsoft's renderer does, which gives that smooth flow of the video, without micro-stutters.

Therefore, there must be something that Microsoft's renderer does, which gives that smooth flow of the video, without micro-stutters.The only way without using any kind of motion interpolation, would be to use frame blending as mentioned above. This is at opposition with the goal of madVR, which is the highest quality video playback.

[agustin9]

But i think madshi said that playing 24p in 60hz using madvr isn't as smooth as evr, that it's on his todo list

so the problem should be with no matching refresh rates

Adjustable shortcuts for deinterlacing and IVTC mode would be very nice, especially until telecined material can be auto-detected.

I was also thinking it would be nice to automatically switch deinterlacing on when switching to film mode (CTRL+ALT+SHIFT+T), fwiw.

use lav video in cuvid mode, but force it to output rgb32 and use evr cp.
that is what i suggest to anyone who can't use madvr for some reason.

Although, before you do that, you have tried bilinear chroma in madvr?
Also, you can try overclocking the gpu a little.

facing a very unique problem.some time ago i posted this
i am having an unusual problem.some 1080p videos run fine on my laptop c2d 2ghz mobilty radeon 4570 with screen resolution 1366*768(60hz) but when i try to run the same video from laptop through hdmi on a 1080p(60hz) LG LCD TV there video lags with frames dropping continuously.backbuffer & render queue are almost always 1-3/8 while decoder & other queue are full.as i understand playing 1080p video on a 1080p screen should be the easiest case scenario or am i missing something.

@namaiki,card ram is 256mb & yes there is a difference when i make video window smaller.gpu-z shows card load at ~70% when window is resized to ~480*360.how can i see the gpu-z window in full screen video playing?

madshi's reply
The bigger the output resolution, the more GPU RAM madVR needs. It might be possible that 256MB is not enough for 1080p playback, I'm not sure. I plan to make the queue sizes adjustable soon, so you can save GPU RAM. That might make it work for you.

now i am facing the exact same problem on same 2 videos on an asus laptop having core i5 2.4GHz,4gb ram,windows 7 x64 sp1 & nvidia GT540m 2gb card.madvr 0.80 windowed mode with all default settings & use separate device for presentation off.these 2 videos play fine full screen on laptop 1366*768 screen.however when connected to LG 32" 1080p TV these 2 videos show massive no. of delayed frames & continuous increase in dropped frames with render queue dropping sometimes to 5-6/16 & back buffer queue 0-3/3 while decoder queue & upload queue are full.this problem only happens on 32" 1080p LG TV watching in full screen but these same videos run fine on laptop screen in full screen mode & in a smaller video window on 32" TV.i am using only lav filters & pot player but also tried mpc-hc with its own filters with same result.

16 is a rather big queue, try to manually decrease the size.
Its also possible that the performance just isn't enough if it uses the iGPU instead of the dGPU (i assume its one of those hybrid things). Maybe try forcing the dGPU?
Also try choosing faster algorithms, like bilinear, just to check if thats a cause.

Does this GT540m card really has 2gb dedicated ram (on the card) or is this a typo ? What is the speed of this RAM ? Is it DDR2 , DDR3 or DDR5 ? Can you post the values reported by GPU-Z? (just memory size and Bandwidth should be enough)

[whitestar999]

@nevcairiel,i used gpu-z & even enabled logging option while video was playing in full screen just to make sure.gpu load never went above 45% & memory usage was ~330mb.i added pot player in nvidia control panel application settings to use nvidia max performance mode & confirmed it again by monitoring gpu usage in gpu-z.

@Pat357,the 2gb ram is dedicated along with 4gb system ram.it is ddr3 with 128bit bus width & 28.8GB/s bandwidth.

edt:tried bilinear too with same result.even turned subtitle animation off but still no change.

Disable the Auto settings and lower the queue settings (12 should be fine in most set ups). Also increase the back buffer value in fullscreen mode (experiment values between 6-10, 8 also worked on alot of systems). hopefully it works for you.

Feature Request: CPU/GPU usage percentage in OSD instead of having to juggle between video and GPU-Z. Thank you!

EDIT: I just tested both those files. Working flawlessly here even on low end system using the values mentioned. Hope it helps!

[whitestar999]

will try your suggestion paladin77 later as i don't have access to TV now.btw your msi notebook resolution is not full HD.i can run these videos fine on my laptop 1366*768 screen.i only face problem running these 2 particular videos on a 32" full HD TV in full screen mode & even there i can run these videos fine in a small video window.

[Paladin77]

hehe. I know I connect the GPU to a syncmaster for testing. Besides its not the only system I test on. You need to raise the back buffer values and experiment between values mentioned. IF all fails there are extra last resort settings you might need to try. But personally I don't think it will come down to that.

Hello!

What do you think about the idea of ​​adding «Luma range» setting, by analogy with HaaliVR? It would be very useful, because on some reason madVR uses the full Range 0-255, where a need limited 16-235. :(

There already is such an option.
Its under Devices -> <your device> -> Properties, a RGB level dropdown.

First, I apologize for my English.

My problem is that some videos do not look right. But I do not fully understand why. Example:
1) madVR PC levels - incorrect - http://2.firepic.org/2/images/2012-01/02/g0hwophrb0uq.jpg
2) madVR TV levels - incorrect - http://2.firepic.org/2/images/2012-01/02/f4e7g7ia8l2n.jpg
3) HaaliVR TV Luma Range - correctly - http://2.firepic.org/2/images/2012-01/02/e6gqnl043knj.jpg
4) HaaliVR PC Luma Range - incorrect - http://2.firepic.org/2/images/2012-01/02/k0c8jwoml5nk.jpg

edit: The problem appears only with some files. Ctrl+J says Full range. I think the reason is this. If so, I would like manually change this value in madVR settings.

The only way without using any kind of motion interpolation, would be to use frame blending as mentioned above. This is at opposition with the goal of madVR, which is the highest quality video playback.

I'm going to make a wild guess, but I think the reason why it doesn't work in madVR, but it works in EVR, is the different algos used to compute the frame presentation timestamps, and not the use of blending/interpolation.

What follows is pure speculation on my part, but it could be that this is how madVR does things:

madVR may take all the consecutive frames, and split them in batches, and for the frames in one batch, it pre-computes equidistant presentation intervals, like:
0.1/0.3/0.5 for the first batch of frames
0.7/0.9/1.1 for the next batch of frames, and so on

But when doing 23.976 fps, and displaying on a 60 Hz display, something happens sometimes (maybe just floating point errors accumulating) that two consecutive batches end up with overlapping timestamps:
0.1/0.3/0.5 for the first batch of frames
0.4/0.6/0.8 for the next batch of frames

And when it's time to show them on screen, they're still displayed in the order of their timestamps 0.3 -> 0.4 -> 0.5. And that's the cause of the odd-looking micro-stutter, where the video seems to be making a sudden back-step in motion (the first frame from the second batch, ends up being displayed before the last frame of the first batch), just to resume immediately after.

Like I said, it's a wild speculation.

Anyway, "perfect playback" is an ideal, which in the case of presentation at the "ideal time-stamp" is not achievable (since the system clock, as well as any other clock, in a computer, is not accurate, and compensation for its jitter can not be done accurately because it's not quite deterministic, for a start), so playing a bit with the display presentation timestamps in order to get a smooth flow of the video should not be a "sin". ;)

i'm guessing splitter or decoder problem. what are you using?

This should explain my problem a bit more clearly.

As you can see, the actual frame rate is 23.976 and I do NOT want to do 3/2 pulldown. I want to run the tv refresh rate at 24fps and let Reclock do its job. The difference in frame rate is due to the way DVD authors stitch the video together. The very beginning part with the studio logo(s) is probably in 29.97 since it is designed to be put on DVDs. The movie is usually 23.976 progressive which is then flagged with repeated frames (pulldown) to make it comply with the DVD requirement of 29.97. MediaInfo is smart enough to ignore the repeated frames and report the true FPS on the film parts. However, MediaInfo is designed for files that are consistent for the entire file, which DVDs are not.

Madshi, is there a way for MadVR to detect this from the .vob file while playing. Right now the solution is to enter 1080p24 for auto refresh rate. Some of my rips are at 29.970, so 24fps will not work.

i'm guessing splitter or decoder problem. what are you using?I use the LAV Video Decoder (YV12 output, i.e. same as in source) and LAV Splitter.
For the test, I switched on the built-in MPC-HC/PP filters. The results are the same.

[Andy o]

Please list all the relevant hardware and software (including filters) you're using. If possible post a sample of the video, or at least some information about it. Like, is it interlaced?

[zmaster]

Please list all the relevant hardware and software (including filters) you're using.Hmm... GPU? NVIDIA GF 9800GT.

Win 7, MPC-HC or/and PotPlayer, LAV Filters. In this case, I do not use video processing filters.If possible post a sample of the video, or at least some information about it. Like, is it interlaced?I can give links to the video itself (I hope the links work...). Two examples where there is a named problem:
