madVR - high quality video renderer (GPU assisted)

[shimaflarex]

Smooth motion mode with present several frames in advance doesn't seems to work consistently for me. Sometimes it keeps flickering between the current and past frames, it happens even when video is paused. The OSD also flickers.

Maybe it's the same problem reported when seeking, but for me it also happens when starting playback on fullscreen exclusive mode or switching from overlay to full screen. It seems to get better after a while, but I still get some random flickering.

But yeah, it looks very good when it is working. Thanks madshi!

Edit: Disabling "Use separated device for presentation" seems to fix it.
Edit2: But it does seem to cause random framedrops =/

[Heuer]

Works superbly here - at last I can watch 'House of Cards' without it jumping massively. I also do not have a problem with settings not being saved.

All in all I am delighted. Thanks Madshi.

[madshi]

For those of you who can't change settings:

Please do *not* change the madVR folder permissions. Well, of course you can do that, and it will "fix" the problem, but it's not really the intended solution. I've not had the time yet to check whether I can reproduce the problem, but just in case: Please check "HKEY_CURRENT_USER\Software\madshi\madVR\Settings". The settings should be saved there even if madVR can't save "settings.bin" into the madVR folder. So I'm really confused why changing the settings doesn't work. Writing to the registry to HKEY_CURRENT_USER should always work, even with limited access right accounts! So please check if that registry key and value exists.

Just as an explanation: Win7 and Win8 have a "VirtualStore" folder where they automatically store files if applications try to create a file in a folder they don't have write access to. So basically the madVR "settings.bin" file was written to the VirtualStore by the OS whenever madVR tried to create it in the madVR folder. This was not intended by me, so v0.86.0 now checks whether it can write to its own folder before trying to create "settings.bin". As a result the file is never stored into the VirtualStore, anymore. If madVR can't write to its own folder, "settings.bin" is not written at all. I thought this shouldn't harm because the settings are always also written to the registry - and that should always work.

Thanks a lot for the detailed explanation, now it makes sense. I have checked that registry path and for me it only contains these entries:

(Standard)
LastSettingsKey
Settings (shouldn´t this be a subkey? it´s a binary value with "0 0 0 0")
ShowOsd
ShowOsd_

So it seems there is something definitely going wrong if madVR doesn´t correctly write the settings there. Just FYI, I have full access rights to that folder!

EDIT: It looks like madVR doesn´t create a Settings subkey but instead it creates a Settings binary value (see above) and thus madVR cannot store and read-back any values. Should be easy to fix for you!

To expand on the corrupted seeking (assuming someone hasn't done this already), with FRC on, after seeking, it seems to flash between the frame you seeked from to the frame you seeked to for a few milliseconds, but only when you have "use a separate device for presentation" enabled. So if I seeked from frame 5 to 1005, it would display 5,1005,5,1005,5,1005 for a few seconds before continuing on as normal (1006,1007...)

Disabling "use separate device for presentation," the previous scenario goes away, but introduces a new problem: tons of framedrops at seemingly random times. The queue that goes to 0 is the backbuffer.

This is all at 60hz (without reclock), and I am of course sticking with the non frame drop method, but these things should still be brought up. Again, not sure if someone has articulated it this clearly, so here I am.

win7 x64
gtx 680 - 314.07 driver

But, looks amazing while it works. I have definitely been looking forward to however you were going to deal with this problem and it exceeded my expectations. God speed on wringing out these little bugs people have :p

After more tinkering this isn't 100% accurate. With "use a separate devices for presentation" on, I still get dropped frames, but much less often than without. 1 every 10 or 30 seconds it seems, maybe even less or more depending on.. who knows. However, I did stumble on that using the AR filter was making these drops happen a lot more often. Turning the AR filter off (using jinc for both upscaling options) even further reduced the amount of frames dropped (can go many minutes without getting any drops). It seems the only thing all of this has in common is that it's always the backbuffer queue that goes to 0 whenever framedrops happen.

To summarize, it seems I must have the use a separate device for presentation enabled to stop the dropping of a vast amount of frames, and then turning the AR filter off even further reduces the amount of frames dropped to a very very little amount.

The Hobbit looked totally smooth to me at 48fps. So maybe it would be an option to let SVP only double the movie frame rate to 47.952fps and then let madVR FRC that to 60Hz? Just a thought, though. Your display probably can't sync to 48Hz?

The only question is if FRC is on or off. If it's on, with 59fps@59Hz it will blend every frame, resulting in some lost sharpness. If it's off, things will be just as they are with older madVR versions. Whether FRC is turned on/off depends on your settings and which framerate the upstream filter reports to madVR.

Yes I might try that, either doubling with SVP to ORIGINAL * 2 = 47.95~, or ORIGINAL * 5 / 2 = 59.94~ and then use madVR to help with the slight difference between that and my display. In this case can I clarify that

1) madVR listens to the upstream filter, ie ffdshow outputting 48hz for example?
AND
2) madVR smooth set to "only if there would be motion judder without it..." should help with the slight differences between refresh rate and output rate even if its tiny like 0.06~hz difference? Thanks again.

[6233638]

Are you using the old or new FSE path? Do you have the GPU and presentation queues set up high enough? (At least 8, the more the merrier)?

There should be no visible judder/ghosting with 24p@60Hz with FRC on. I'm very sensitive to motion related problems like this and for me with real life content FRC works great with 24p@60Hz. With computer type test patterns I can see some small degradations, but it's still much *MUCH* better than with FRC off. That said, 50fps@60Hz is not as good as 24p@60Hz, for whatever reason...

If this doesn't work well for you I can only imagine that something goes wrong on your PC. Or maybe you're testing with extreme content. Try a normal movie. And maybe try resetting to default settings, just as a test...I am using the new FSE path, and was set to 8 queues. Even at 16, I'm still seeing the same thing.

The image is somewhat smoother, but still judders, and has noticeable ghosting from the frame blending. It reminds me of the old NTSC > PAL transfers we used to get back in the 90s, but not quite as bad.

I was checking with the Casino Royale Blu-ray, as that is my go-to disc for testing anything, as it includes scenes for just about anything you need to evaluate on a display/video processing.

As I said though, maybe I am just really sensitive to it, or maybe it depends on how good the motion handling of your display is. If your display is already blurring everything with motion, maybe you won't notice the blended frames.

A quick example: Frame 1 (http://www.abload.de/img/frame-11xr5e.jpg) Frame 2 (http://www.abload.de/img/frame-234r5k.jpg) Smooth Motion (http://www.abload.de/img/blendr8qyf.jpg)

I think I prefer the judder to less judder plus ghosting.

[rahzel]

Yeah, I dont own Panasonic VT30 plasma anymore, but what I remember is:
1. VT30 did flicker A LOT when being set to 23Hz/24Hz. When setting the display to 60Hz, the flickering was not eliminated completely, but it helped a lot.
2. VT30 and also VT50 has also issues with digital false contouring ( panning scenes ) and they are very bad especially on european models when watching at 50hz ( so called 50Hz bug ), but the false contouring is observable also at 24Hz. Also here, setting the panel to 60Hz, reduced the false contouring issue to something more acceptable level.

Maybe someone with ST/GT/VT series of Panasonic plasmas can confirm this and do some testing. I think many owners would then benefit from the madvr smooth motion feature ( excluding the motion artifacts, Panasonic plasmas offered in 2012 the best PQ ).
I have followed the 2012 Panasonic plasma line closely (I'm a long time poster/member at AVS and HDJ). AFAIK, the VT50 fixed the false contouring issues that the VT30 had... 96Hz on the VT50 is virtually problem free. There is some very minor flickering, but most people don't notice it. FRC is nice for ST or GT owners, though, which only have a 48Hz option vs the the 96Hz option on the V series.

When my ST50 receives a 24p signal and my ST50 converts 24p to 60Hz, motion is smooth, but bright panning objects cause a flicker effect (easy way to see it is on scrolling end credits on a black background). Before the FRC option, this is what I used and I lived with the flickering artifacts. It was either that or output 60Hz and have my HTPC convert 24p to 60Hz, but this wasn't as smooth... until now. :)

[aufkrawall]

Sorry if this has been asked already, but why does smooth motion conversion not work if display is at 60Hz and video has 29.97 or 59.94fps?

But MANY thanks for that new feature, it's really kind of salvation. :D

Will test if I still experience my frame drop issue with 60fps videos and provide logs if true.

Edit: Issue still exists, here is the debug log:

Take a look at the smooth motion settings, it´s pretty self-explanatory. You can adjust it for 29.97/59.94fps content.

Because 29.97 videos should play smoothly without the smooth motion option... frames will just be doubled to play on a 60Hz display. The smooth motion option is mostly useful for when the frame rate isn't close to or is not an even multiple of the display's refresh rate.

[makakam]

I have vt30e and I've always used 23hz setting (radeon gpu) without getting any flickering or artifacts with madVR.

There's still judder with 59,94fps@60Hz, only the "always" option works.
"only if there would be motion judder without it" should cover it imho.

[n3w813]

If your display can do native 24p that might be the better option. But then, let your eyes be the final judge on what looks better to you. Have you disabled the first "trade quality for performance" option? Maybe it will reduce the sharpness/clarity loss even more. On my projector I'm hard pressed to see a difference in sharpness with FRC on/off, when playing 24p@60Hz. Since my projector can do 24p natively, though, I'm not planning to use FRC myself on this setup. I'll use it on my computer monitor, though, which can only do 60Hz.

By default, the top 2 options in the "trade quality for performance" are checked. Should I uncheck both?

I use my HTPC for both videos and live tv through WMC. By default, the video card is outputting 24Hz. When I switch to WMC or when I play 60p content, accordingly, the output changes to 60Hz but it causes a blackout for couple of seconds while my AVR and TV resyncs. Kinda annoying. If I can stay at 60Hz output and still get judderless playback of 24p content, then I'm very happy. :D

[cyberbeing]

Would it be possible to add an option to temporarily disable FRC during seek as well as window->fullscreen, and delay re-enabling by a couple seconds to allow the render queue and vsync readings to stabilize (preferably independent from the existing delay playback options). Something like this seems like it's needed to avoid the temporary FRC instability and severe blurring artifacts in these cases.

For those of you who can't change settings:

Please do *not* change the madVR folder permissions. Well, of course you can do that, and it will "fix" the problem, but it's not really the intended solution. I've not had the time yet to check whether I can reproduce the problem, but just in case: Please check "HKEY_CURRENT_USER\Software\madshi\madVR\Settings". The settings should be saved there even if madVR can't save "settings.bin" into the madVR folder. So I'm really confused why changing the settings doesn't work. Writing to the registry to HKEY_CURRENT_USER should always work, even with limited access right accounts! So please check if that registry key and value exists.

Just as an explanation: Win7 and Win8 have a "VirtualStore" folder where they automatically store files if applications try to create a file in a folder they don't have write access to. So basically the madVR "settings.bin" file was written to the VirtualStore by the OS whenever madVR tried to create it in the madVR folder. This was not intended by me, so v0.86.0 now checks whether it can write to its own folder before trying to create "settings.bin". As a result the file is never stored into the VirtualStore, anymore. If madVR can't write to its own folder, "settings.bin" is not written at all. I thought this shouldn't harm because the settings are always also written to the registry - and that should always work.

In the registry the Settings value exists but it has no value (regedit says zero-length binary value).
If I move the settings.bin file out of the madVR folder, the behaviour is the same (won't save settings in the registry, or in settings.bin)

[mark0077]

madshi, nothing new to 0.86.0 but for me, even with delay playback until render queue is full checked, I usually get 1-2 frame drops on playback start, or if I have mpc set to repeat a sequence, after the sequence restarts, I can see the queues drop to 0 and I again will get 1-2 drops. Just thought I would mention it as I had a clip on repeat this evening testing something, and noticed lots and lots of frame drops in the stats, all coming from the each start of the sequence. I'm not sure if madVR waits for all queues to fill up before starting playback or just some?

[Blight]

Madshi, FRC's overhead is enough to make it detrimental on low-end cards (nvidia gt520 for example), is it possible to make FRC smart enough to auto-disable itself (even when enabled in the settings) if it detects GPU loads of 99%?
As you are probably aware, with FRC enabled at 100% GPU load frames appear out of order.

Seeking might also trigger the out of order frame glitch, I'm not sure if it requires 100% GPU load to trigger.

I know you can disable FRC, but there are cases where it's beneficial when automatic, for example:
When you only play video, you GPU can handle the load, but if someone also uses a GPU accelerated browser on the second monitor at the same time, out of order frames appear constantly.

[Brotoles]

I guess this might not be a madVR issue, but let me describe my issue please

I use K-lite Codec Pack for my multimedia needs. I have the latest version installed (9.7.5), and it comes with MPC-HC v1.6.6.6517, LAV Filters v0.55.2-16-gd6e6c1f and madVR v0.85.8

I use the LAV decoder filter for almost all of my video streams, and madVR as the video renderer. I have an nVidia GTX 670 with the latest WHQL drivers (v314.07), and Win7 x64.

When I playbak a DVD using this decoder-renderer combination, no subtitles or subtitle overlays (menu highlights, etc) are displayed. But when I use MPC-HC internal MPEG2 decoder and keep using madVR as the renderer, the subtitles and overlays are displayed just fine.

Now here's my doubt - is this a LAV issue, such as: it doesn't feed the subtitle stream correctly to the madVR renderer; or is it a madVR issue, such as: madVR isn't compatible yet with the way LAV handles subtitle streams?

Thank you all for your attention, and have a great day,

Brotoles

[nevcairiel]

A quick example:

As madshi already commented on before, screenshots will always look rather bad with blending, you need to compare and judge from moving images, and not from individual screenshots, so these serve no real purpose, but spread FUD, imho.

[Thunderbolt8]

I tested the madvdtestpatterns with smooth motion on a samsung syncmaster 226 CW (22") with 1680x1050 resolution and to me theres still some difference visible between 60fps content on this 60Hz display, which runs smooth as butter, and the 23 & 24fps test patterns which are not presented as smooth as the former content. It definately looks a great deal better than without smooth motion, but the difference, at least with these test patterns, is still rather obvious.

are those test patterns especially sensitive or is this maybe due to the 1680 resolution?

[nevcairiel]

Its not meant to make 24p content as smooth as 60fps content, its just meant to remove motion judder. Its not a frame interpolator, it does not invent new frames to create more fluid motion, it just presents the existing frame in a way that avoids any motion judder.

madshi should make this clear in big red letters, judging from how many people misinterpret this ;)

[dansrfe]

I'm very interested to hear nevcairiel's, madshi's, and everyone else's opinions on frame interpolation (SVP) vs frame blending (FRC). I know this is a subjective question but I'm only looking for opinions.

[rahzel]

I'm obviously not nev or madshi, but I personally hate the effect of frame interpolation... it ruins the film 'look'. This option is available on many flat panel TVs now and most people leave it off, especially for film. I have a frame interpolation setting on both my LG LH90 LCD and Panasonic ST50 plasma and leave it off for all content. I just want film judder removed on my ST50, and that's the main purpose of FRC... not to make film look like 60fps with frame interpolation.

I'm sure if madshi wanted to, he could add a frame interpolation option... but I don't see why anyone would want it TBH. :scared:

[DragonQ]

You'd better get used to the loss of the "film look" if 48 fps filming catches on.

[dansrfe]

Personally I hate the blurring that happens when the camera pans. I haven't tried SVP before but as DragonQ has pointed out, films will be moving towards higher and higher fps as are refresh rates already. In the next decade we'll most likely start to see and get used to the new normal standards.

[rahzel]

I somehow doubt 48fps will catch on... reactions from people viewing clips of The Hobbit at 48fps seemed to be mixed... the negative reactions were the same negative reactions when people saw frame interpolation for the first time. It might benefit 3D, but for 2D, I'd rather it not be 48fps.
If film gets a new standard for framerate, I hope it's 30 rather than 48.

[DragonQ]

What would be the point of moving to 30 fps? :/

I prefer 50 fps to 25 fps for TV, so I have no issue with 48 fps rather than 24 fps for film (except of course that it's yet another standard that will mostly requires new TVs).

Frame interpolation is different though - I haven't seen it done well yet (MotionFlow increasing 24 fps to 600 fps was just eww) but admittedly I haven't seen many new TVs.

[Boltron]

Personally I am very sensitive to judder and do all that I can to eliminate it as much as possible. I do use SVP to convert movies (takes about 7 hours a movie) that bother me the most, the trick is to get a good balance between minimal artifacts and smoothness.

I am very, very happy madVR now has this feature.

[JarrettH]

This feature looks great on the Intel HD 2000 here. I changed my buffers from 3/4 to 4/6 by default too.

[Thunderbolt8]

Its not meant to make 24p content as smooth as 60fps content, its just meant to remove motion judder. Its not a frame interpolator, it does not invent new frames to create more fluid motion, it just presents the existing frame in a way that avoids any motion judder.

madshi should make this clear in big red letters, judging from how many people misinterpret this ;)so how is it supposed to look? bascially that way that the test pattern looks about half fine, but that any 24fps real movie content should look about as smooth on 60Hz now as it does on a native 24Hz TV?

[rahzel]

What would be the point of moving to 30 fps? :/
It's somewhat of a compromise. :) The difference between 24 and 30 is pretty noticeable. Plus it will avoid 3:2 pulldown on 60Hz displays. I'm just thinking for North American displays, but don't most PAL displays support 50Hz and 60Hz?

so how is it supposed to look? bascially that way that the test pattern looks about half fine, but that any 24fps real movie content should look about as smooth on 60Hz now as it does on a native 24Hz TV?
Didn't look at the test pattern, but it should look fairly similar to what it looks like without it, but with less jerky motion -- most noticeably on panning scenes or objects panning across the screen. It should look pretty much the same as 24p being displayed on a set that properly handles 24p (72Hz, 96Hz, 120Hz, 240Hz etc. displays) without frame interpolation enabled.

[dansrfe]

That's another thing. Hopefully in the next 10 years we'll have no NTSC or PAL. A small selection of audio formats and bitrates. A small selection of video formats, frame rates, and one primary and matrix. The graphics/video space definitely needs to become much more unified.

[leeperry]

I somehow doubt 48fps will catch on... reactions from people viewing clips of The Hobbit at 48fps seemed to be mixed... the negative reactions were the same negative reactions when people saw frame interpolation for the first time. It might benefit 3D, but for 2D, I'd rather it not be 48fps.

48p perception strongly depends on the shutter speed of the video camera, you can get 48fps that will look like a soap opera or 48fps that will look just as blurry as 24/30fps without the "smoothing" effect.....not everything is black or white in this world ya know: http://www.mediacollege.com/video/camera/shutter/shutter-vs-fps.html
http://www.mediacollege.com/video/camera/shutter/ ;)

You seriously expect me to say that based on your description? Sorry, not possible.
Sammy's TV certainly do a lot of things right IMO, too bad their DNIE engine isn't either finetunable or defeatable but their motionflow thingie in its lowest "crisp" mode looks über-smooth without artifacts or unnatural effect and their dynamic intra-picture contrast would be well worth your time to have a look at if you had a few mins to kill at your local supermarket.

Can't wait for them to stop milking the LCD cow and finally release the OLED screens I've been craving for way too long now....I've come to realize that LCD will never make happy and neither will DLP projectors due to their utterly noisy fans and RBE's, so I'm back on CRT FTW: dead silent, 20K:1 CR, 96Hz support, abysmal black level, how hard was it huh.

BTW, he's a worst case scenario 20 secs long 24p sample if you wanna hurt your eyes polishing your blending thingie: Death.and.Life.of.Bobby.Z.mkv (https://mega.co.nz/#!3hZXlAgD!GVsDVEl0YtYglmN3fXttul2B2nV4pHZyO9UAuAISJA4)

As long as there's no SOE, I don't really care what the frame rate is.

[Niyawa]

I have a question, madshi mentioned that ReClock would still be recommended to use even with the smooth notion enabled but I'm not sure if I should let ReClock adapt 23.976 > 24p or if I should just leave it at original speed. Sorry if this has been asked before - did a little lurking but it's still in my mind.

[kasper93]

@Niyawa: Reclock is recommended to provide stable audio clock and timestamps. No need to change speed, but it's your decision really ;p

[Niyawa]

@Niyawa: Reclock is recommended to provide stable audio clock and timestamps. No need to change speed, but it's your decision really ;p
I get that, just wanted to confirm, thanks. madshi, I promise I'll use the bugtracker next time! I honestly forgot about it when I mentioned the issue with settings.

[THX-UltraII]

Will there be noticable performance differences when using madVR and LAV video decoder between:

Geforce 560ti
Geforce 650
Geforce 650ti

And is a fast CPU required anyway when playing only 1080p Blu-Ray content on a 1080p display device?

And why does changing the settings Chroma Upscaling, Luma Upscaling and Luma Downscaling has influence on my CPU/GPU while I m playing 1080p Blu-Ray content on a 1080p display device?

[DragonQ]

Only Chroma Upscaling should affect 1080p playback on a 1080p screen (because the chroma resolution will be 960x540).

[THX-UltraII]

Only Chroma Upscaling should affect 1080p playback on a 1080p screen (because the chroma resolution will be 960x540).

Can you explain a little more about this? Don t understand what you mean exactly. Will I benefit a lot from a high quality chroma upscaling setting when playing 1080p blu-ray on a 1080p display device?

[iSunrise]

Will there be noticable performance differences when using madVR and LAV video decoder between:

Geforce 560ti

That depends on your scaling settings, your source files and your target resolution. There´s no real answer for such a question. A Geforce GTX 660/Ti should handle almost everything apart from some very extreme scaling settings (very high Jinc settings on both luma/chroma). If that is too expensive, you should go with the Geforce 650/Ti that is on your list. Stay away from GDDR3 models if you can and buy cards with GDDR5 and at least a 128bit (650/Ti) or 192bit (660/Ti) memory interface, because madVR likes bandwidth.

And is a fast CPU required anyway when playing only 1080p Blu-Ray content on a 1080p display device?
That is not an easy question to answer. Yes and no. madVR needs a fast (the faster, the better) GPU, mostly, like the ones you mentioned. If you mainly watch progressive content and you´re on a 1080p resolution, you should be fine. If you had written down a short list, we would have a better idea with what exactly you consider to be a "fast" CPU. Fast ist a very subjective word.

And why does changing the settings Chroma Upscaling, Luma Upscaling and Luma Downscaling has influence on my CPU/GPU while I m playing 1080p Blu-Ray content on a 1080p display device?
Chroma needs to be upscaled/upsampled to the target resolution, because it´s stored at only half the resolution of the luma resolution with almost any content out there (Blu-Ray, DVD, etc.).

Luma upscaling settings should not make a difference if your source resolution = target resolution. Luma downscaling only is active if you´re target resolution is lower than your source resolution, which is not the case very often (e.x. only if you still have a 1680x1050 screen and you have 1080p content).

[Dodgexander]

Doesn't seem to work very well with interlaced 1080i 25fps TV recordings I have, it introduces a lot of judder. 1080p@ 25fps works great though as does 576i 25fps material.

On a second computer, I can't get it to work without bad judder with a 24fps movie either, but I am not sure if thats because the video card is so low end (Radeon HD5570) or not. What kind of requirements are needed?

Oh settings are all default on both computers btw.

[THX-UltraII]

thxz for your reply iSunrise. Let me ask the question more simple:

Right now I have a GTX560ti. Would switching to a GTX650ti be an upgrade or downgrade when madVR is the only purpose of the card (and keeping in mind that I ONLY play 1080p on a 1080p display device)?

And with bandwidth you mean Bandwidth in GB/s? Because the GTX650ti has 86.4 and the 560ti has 128. But the GFLOPs and Transistors of the 650ti are higher than the GFLOPs and Transistors of the 560ti.

downgrade, for both game and madVR

The 650Ti is like a cheap version of the 660Ti and thus more of a downgrade. So there´s no benefit at all. The 560Ti is a quite capable card with high bandwidth. It´s good for gaming and madVR, so just stay with it.

Yes, exactly. The tiny bit higher throughput in GFLOPS is not that important if you only need to upscale chroma and not luma.

650Ti is a cheap version of the 660, not 660Ti. :p

I m having lipsync problems during movie playback. Could it be that I have a too high Chroma Upscaling setting that causes lip sync problems? (http://forum.doom9.org/showthread.php?t=167229)

What is you recommendation for the Chroma Upscaling setting when only playing 1080p on a 1080p display?

Yes, different ASIC. Typing mistake.

Not an easy answer for that. If you lower your chroma upscaling settings, does it go away? If you´re using EVR instead of madVR, is there a lip-sync problem? Take a look at your GPU usage (GPU-Z) and CPU usage (task manager), while you´re playing the files. If you´re CPU/GPU is not overloaded, it´s not a problem of your hardware performance, but more likely your settings/filters/playback chain or your source files.

There´s no real recommendation, because every algorithm comes with positives/negatives, you need to judge for yourself by testing them. The defaults should be fine.
